Title: Improvements in or relating to navigational instruments
IPC: G01C21/14
Filed: 1945-06-19
Abstract: 596,609. Course-recording apparatus. BARNES, J. W. June 19, 1945, No. 15649. [Class 97 (ii)] A stationary light-beam is projected on to a reflector which is moved in accordance with the co-ordinates defining the position to be indicated. The apparatus shown is intended to be mounted in an aircraft above the navigator's table 48 carrying a map on which the ground position of the aircraft is to be shown. Shafts 20 and 26 are driven by amounts proportional to ground distance travelled in a N-S and an E-W direction respectively, that due to shaft 20 being transmitted to a mirror tube 33 by lead-screw 23, nut 24 and arm 35. The nut 28 on the shaft 26 rotates the mirror 31 about pivots 31x carried in the tube 33 by a spring-urged bracket mounted in the instrument frame and contacting an arm extending from the mirror. A zero-adjusting mechanism for the mirror operated by an arm 56 is interposed between the bracket and the mirror arm. To eliminate distortion arising on rotation of the tube 33 when the mirror is at angles other than 45 degrees, the transmission mechanism is adapted to apply a small correcting movement to the mirror. The image projected on to the map is that of an arrow-shaped graticule 37 mounted on a sleeve 43 adjustable on the end of a tube 36, coaxial with, but separate from the mirror tube 33. In order to maintain the arrow-head in the direction in which the aircraft is heading, the graticule tube is driven by a worm 39 and worm-wheel 38 from a compass repeater motor 42. The tube may be initially synchronized with the compass controlling the repeater motor by rotating the worm-shaft by the slotted spindle 47 until the appropriate setting on the attached scale 44 is opposite the pointer 45 fixed to the tube 33. Rotation of the sleeve 43 enables the graticule image to be synchronized with the initial aircraft heading and axial movement focuses the graticule in the optical system consisting of the lamp 46 and lens 32. To cancel out rotation of the graticule image caused by rotation of the tube 33, the latter is connected by linkage 51-53 to a lever 50 which slides the worm along its shaft, thus effecting a compensating rotation of the tube 36. The ground position co-ordinates are transmitted from differential gears 3, 4 to the shafts 20, 26 via clutches 18, 19 which enable zero adjustments to be made from knobs 29, 30 and variable gears 15, 16, which may be adjusted by a lever 17 in accordance with map scale. The differential gears 3, 4 are driven according to N-S and E-W air mileages respectively by repeater motors 1, 2, in conjunction with an air position indicator, and according to N-S and E-W wind speed by shafts 5 and 6 respectively, which are driven by a constant speed motor 7 via continuouslyvariable friction gears 8 and 9 respectively, the effective ratios of which are determined by a resolving mechanism indicated generally at 10 into which estimated or known wind speed and direction may be set by knobs 11 and 12 respectively.

Cutting slices in succession. - Apparatus for making sandwiches comprises a conveyer, means for cutting bread slices and depositing them on the conveyer, means for cutting and delivering meat slices on to the bread slices, and means for cutting further bread slices and depositing them on the meat covered bread slices. As shown in Fig. 1, a conveyer 20 running over rollers 18 in a longitudinal gap in a table 15, is trained over end rollers 21, 22 and is tensioned by a jockey roller 24. Bread slices are cut in a machine 58 having a disc knife which moves in a planetary path, the machine being carried by a table 25, and delivering its slices over a shoot 55 to the conveyer 20. The slices are buttered by a device 76 which may be constructed as described in Specification 292,160, [Class 28 (i), Bread-making &c.]. The buttered slices pass to a meat slicer 63 of the disc knife reciprocating carriage type, the meat slice being deposited on the bread slice by a delivery rack or stacker 66. The sandwich is then completed by a second bread slice which is cut by a planetary disc knife machine 90 and deposited on to the meat slice by a swinging fly 91 resting, whilst it receives the slice, in the shoot 90<a>. The fly is operated, through bevels, from a shaft 94 having a crank 95 at its end, the crank having a pin which engages between two collars 96 on a vertically movable rod 97. The rod is depressed, at intervals, by a pawl 99 on the shaft 100, and is returned by a spring 98. The shaft 100 is driven by sprockets from the main shaft 40 of the apparatus. A motor 30 drives the conveyer and the slicing machines through reduction gearing in synchronism. The completed sandwiches are passed to a plate 112 covered with paper in which they are wrapped.

Title: Electrolytic plating
Inventor: MANSON WALTER J
IPC: C25D7/06
Filed: 1958-05-19
Abstract: 857,351. Electroplating. KENMORE, H. May 19, 1958, No. 16060/58. Class 41 In a device for continuously electroplating wire, tube or strip material, which is continuously formed into the shape of a horizontal helix and rotated so as to move.lengthwise along at least two horizontal rollers positioned above a bath structure and supporting a multiplicity of consecutive individual coils of the helix, the lower portions of the coils dipping into an electroplating bath, at least one of the supporting rollers comprises a length of an electrically conducting surface, on which a plurality of the coils is supported, electrical contact means being provided to feed an electroplating current to the roller whereby to supply the current to each of the said coils of the helix, and means are provided to spray the electrically conducting surface of the said roller or rollers with the solution of the electroplating bath. As shown the material 10 to be plated is formed into a helix and supported on rollers 20 and 21 over the electrolytic bath 28. These rollers may be sufficiently conductive of themselves, or may have a conducting tape wound around them. Electric current is supplied to the rollers through collars 57 on the rollers, and carbon brushes mounted on the assembly 60 which is supported by the frame 36. The rollers 20 and 21, where they support the helix, but not the collars 57 are sprayed with the bath solution from perforated tubes 39 and 40. The helix may be oscillated backwards and forwards along the rollers by means of a slowly oscillating guide-rod (not shown) running parallel with the rollers, and carrying guide pins that fit in between the coils of the helix. Alternatively, the rollers 20 and 21 may be slowly oscillated to produce the same effect. One or more pretreatment or water-wash baths may be provided under the rollers 20 and 21, so that the helix passes through them before it reaches the plating bath. In this case the rollers where they contact this part of the helix are sprayed with water, which is caught in drip pans (not shown) which empty into the wash baths, to avoid diluting the liquid in the pretreatment baths. The apparatus may be used to plate copper on to steel wire. Specification 775,769 is referred to.

Title: Improvements relating to the manufacture of acetic acid, acetaldehyde or acetone or mixtures containing the same
IPC: C07C51/10
Filed: 1923-06-22
Abstract: Acetic acid, acetaldehyde or acetone or mixtures thereof are produced by passing methane together with carbon monoxide and/or carbon dioxide under pressure and at temperatures below about 500 DEG  C. over a catalytic material.  Said material comprises either a hydrogenation catalyst such as copper, iron, nickel, cobalt, palladium, platinum, palladium black or platinum black, or nickel carbonate or other metallic carbonate which dissociates at temperatures below 500 DEG  C., or mixtures thereof.  The catalytic material may form the tubes or apparatus in which the reaction is effected, or it may be mounted on porous substances or employed as wire, gauze, &c., whilst when carbonates are employed, other carbonates such as sodium carbonate may also be present.  The oxides of carbon are preferably employed in excess.  Moreover, the reaction gases may be continuously circulated through the apparatus.  Examples are given of the preparation of acetaldehyde from methane and carbon monoxide and of acetic acid from methane and carbon dioxide, employing pressures of 12-50 atmospheres, temperatures of 120-300 DEG C. and catalysts consisting of finely-divided iron or nickel carbonate, the latter preferably mixed with finely-divided nickel or iron.  The Provisional Specification is not restricted to the use of pressure.
Patent GB-806931-A (GB)
Title: Improvements in or relating to the production of 5-(4-hydroxybutyl) hydantoin and intermediates therefor
IPC: C07D233/76
Filed: 1956-05-25
Abstract: The invention comprises (1) an aqueous solution of a -amino-e -hydroxy-capronitrile, and its preparation by reacting g -hydroxyvaleraldehyde, hydrogen cyanide and ammonia in aqueous medium without allowing the aldehyde and HCN to come into contact in a non-acid medium unless the ammonia is present; and (2) the preparation of 5-(4-hydroxy-butyl)-hydantoin from the said capronitrile by reaction with carbon dioxide.  The first step may be carried out by adding the components simultaneously to an aqueous medium, or by rapidly adding the ammonia to a non-alkaline mixture of the other two reactants, e.g. one of pH 1-6.  The quantities are preferably around stoichiometric, e.g. aldehyde / cyanide / ammonia as 1 : 1 : 1.2.  The temperature may be 10-40 DEG  C., and the ammonia may be aqueous or anhydrous.  The hydroxyvaleraldehyde can be used as the acid hydrolysis product of dihydropyran.  An example is given of the process, the product being detected by paper chromatography and by acid hydrolysis to a -amino-e -hydroxycaproic acid.  The formation of the hydantoin may be carried out by direct carbonation of the reaction product of the first step, preferably at elevated pressure and temperature, e.g. 60-120 DEG  C.; this step is also exemplified. The product is an intermediate in the synthesis of lysine.

Title: A Linear Motion Device
IPC: G21C7/14
Filed: 1968-04-05
Abstract: 1,188,084. Electric motor driving arrangement. BORG-WARNER CORP. 5 April, 1968 [22 May, 1967], No. 16589/68. Heading H2A. [Also in Divisions F2 and G6] Relates to a linear actuator, e.g. for raising and lowering control rods of a nuclear reactor, comprising a disengageable screw-and-nut mechanism driven by an electric motor 12 having a stator 27 coaxially surrounding a reluctance type rotor formed of two rotor arms 34 pivoted at 37 to the inner race 39 of a bearing 41 to allow radial movement of the arms between an activated position (Fig. 2) in which the upper portions 74 of the arms are close to the stator and rollers 47 on the lower ends of the arms engage an axially movable, non-rotatable lead screw 11 and a deactivated position in which the portions 74 move inwardly from the stator and the rollers 47 disengage from the lead screw 11. A bearing 92 mounted in the upper part 19 of the motor frame 14 has its freely rotatable outer race 91 axially extended at 88 to form a stop limiting outward movement of the rotor portions 74 when activated, and bores 97 in the race 91 receive pins 94 on the ends of the rotor portions 74 to synchronize radial movement of the latter. Lugs 79 on the ends of the rotor portions 74 engage the race extension 88 in the activated position and a flange 84 of a fixed sleeve 63 in the deactivated position. Springs 57 between the lower portions 44 of the rotor arms 34 urge the latter towards their deactivated positions. The inner faces of the rotor arms are shaped to permit the lead screw 11 to extend between them. A ring (68) (Fig. 3, not shown) retains the pivot pins 37 in the bearing race 39. The stator 27 is surrounded by a cooling coil 26. The motor frame 14 forms a pressure vessel isolating the stator from any fluid around the lead screw. The stator is a four-pole assembly which may be energized by a multi-phase A.C. or a D.C. supply, in the latter case the poles being cyclically energized to form a D.C. step motor. While the stator is energized the rollers 47 engage the lead screw. On de-energization, e.g. for emergency shut-down of a reactor, the rollers release the lead screw, which is moved by springs and/or gravity to a " safe " position.

Abstract: 694,611. Counting-apparatus. GIOVENCO, O. July 12, 1951 [July 15, 1950], No. 16598/51. Class 106 (i). Apparatus for ascertaining percentage contents of an aggregate comprises a plurality of counters each associated with a foot-operated actuating element and a total-counter which is operable by each actuating element simultaneously with the corresponding counter. Foot switches 11, operated in accordance with the components observed when analyzing a mixture by means of a microscope, are each associated with a counter, e.g. 5, which is operated by an electromagnet 14 in circuit with the switch. A further electromagnet 15 in the same circuit operates a total counter 6. When the total counter registers, say, 100, a switch connected to leads 20 is opened to prevent further operation of the counters 5, 6. The percentages of the various components are thus readily observed. A sound or light signal may be actuated when the total counter reaches the predetermined count.
Patent GB-123118-A (GB)
Title: Improvements in Shuttleless Looms for Weaving.
Inventor: SMITH EDWARD
IPC: D03D47/24
Filed: 1917-11-13
Abstract: 123,118. Smith, E. Nov. 13, 1917. Shuttleless looms.-In a loom in which a weft carrier picked like an ordinary shuttle takes loops of weft from an outside supply through the eheds from opposite sides alternately, the carrier is temporarily arrested at each pick with the weft loop at the desired position within or beyond the selvedge, and after the weft loop is cut the movement of the carrier into the box is completed. The carrier is shaped like a shuttle, and each tip 5, Fig. 4, has a tongue 4 separated from the body of the tip by a groove 7, in which the weft loop is engaged. The weft 10, Fig. 5, from the source of supply passes through slotted eyes at d, f in a guide-plate 9 at each end of the reed, so that a part of the weft extends across a groove 6 in the carrier 2 in position to be engaged by the tongue 4 at the rear end of the carrier as it is picked, the tongue 4 lying in the groove 6 so that the carrier walls prevent the tongue from catching the warps. The carrier is arrested in the desired position by the usual check straps &c., and as the lay F, Fig. 2, moves forwards the end g of a lever 12 pivoted at h to the breast beam E enters a slot in the box front 13 and a groove in the front of the carrier, continued movement of the lay causing the front 13 to. act on a bowl m on the lever and move the lever against the action of a spring n, so that the end g comes against the protected end of the groove in the carrier and moves the carrier fullv into the box. At the same time, a spring-pressed buffer 16, or a spring- pressed lever similar to the lever 12, acts on a lever 15, Fig. 6, pivoted at t in the carrier, and moves it so that a knife 14 is moved against the action of a spring across the groove 7 to sever the weft loop. The levers 12 and the spring buffers 16, or their equivalent levers, are adjustable to regulate the times when the movement of the carrier is completed and the weft is 'cut. The weft-carrier is of sufficient length to extend from the selvedge far enough into the box to operate the swell lever and stop-rod mechanism, and if a narrower fabric is woven a longer carrier is used. A shuttle-relief motion may be used in a fast. reed loom, and the selvedge shedding-mechanism may be arranged to form any desired kind of selvedge.

Abstract: 402,352. Making razor blades. BASSAT, H., Ohligs, Solingen, Germany. June 12, 1933, No. 16717. [Classes 83 (ii) and 83 (iv).] Breaking; shearing.-A machine for use in the manufacture of razor blades is adapted to give a step by step feed to a continuous strip of steel previously perforated, hardened, tempered, ground and nicked, and to break off first the extremity of waste material and then the whole blade as the strip is fed through the machine. The strip 1, fed intermittently between guides 4, 5 by the belt-coupled wheels 8, 9, one of which is rotated by cam, lever and ratchet mechanism from the main driving shaft 17, passes below a cam and lever-operated fixing pin 19 to an oscillatable breaking-off device 41, the latter partially rotates about the axis of the shaft 22 deriving its movement from the cam 40 on the shaft 17, lever 24 and arm 23. The movement of the device 41 is timed first to break off the waste end of material at the leading edge of the ribbon, this falling down a chute 27, and then a reverse movement of the device severs a complete blade and places it over a vertical pin 30 which latter is then moved outwardly, Fig. 1, under control of cam 37 and rod and lever gear 36, 35, to free the blade from the guide and allow it to drop to the base of the collecting pin, the strip is then fed along the length of a blade and the operation repeated. When the pin 30 is completely stacked with blades it is replaced by an empty pin by loosening the screw 32.
