Title: Improvements in or relating to tracer controlled profiling machines
IPC: B23Q35/18
Filed: 1954-06-29
Abstract: 761,407. Copy-milling. CINCINNATI MILLING MACHINE CO. June 29, 1954 [Oct. 12, 1953], No. 19011/54. Class 83 (3). A tracer-controlled profiling machine comprises a hydraulic feed-circuit for effecting a movement at a predetermined feed-rate and including a return-line 59, a tracer-valve 13 operatively connected to said circuit for controlling and changing the direction of feed effected by said circuit, and pressure-operated means 49 responsive to opening of the tracervalve to restrict flow in the return-line. The tracer operates a lever 11 pivoted on a fixed pin 12 to move the valve 13, supplied with pressure by a pump 45 through passages 48, 52. The valve directs fluid to rotate a hydraulic motor M in one or other direction by a hand-set " manual " or " automatic " control-valve 27 which is automatically moved to " automatic " position when the pump 45 is running. Rotation of the motor M rotates an eccentric 28<SP>1</SP> to move valves 34, 35 to control the supply of fluid from a pump 71 to pistons 36, 40, which move slides in perpendicular directions to move the tool and work relatively to each other. When a sudden change in the pattern occurs which, with the high-feed rate, would otherwise cause the cutter to overshoot, the sudden increase in flow through the passage 48 causes the valve 49 to move to the right and cut-off the exhaust-line 59 connected to both pistons 36, 40: The feed-rate is thus reduced until the circuit has adjusted itself to the new direction. In a modification, the tracer-valve controls the movements of the slides without the use of a motor M and eccentric 28<SP>1</SP>.

Title: Improvements in or relating to the treatment of rubber
Inventor: CUNNEEN JOHN IVAN
IPC: C08C19/20
Filed: 1958-06-17
Abstract: Polybutadiene hydrocarbons, e.g. guttapercha, guayule, smoked sheet and pale crepe rubber, and synthetic polyisoprenes and polybutadienes, are treated with sulphur dioxide at a temperature of from 100 DEG C. to 250 DEG C.  The sulphur dioxide may be in solution or absorbed, e.g. in carbon black, or liberated from a compound decomposable at the treatment temperature, e.g. an unsaturated sulphone (of butadiene or isoprene for example), clathrate compounds of sulphur dioxide with phenols such as quinol, paraamino phenol and p-methylamino phenol.  The rubber, in solution or sheet form, vulcanized or unvulcanized, is preferably heated to 130 DEG  to 200 DEG C. for the treatment which may be effected during its mastication, compounding or vulcanization, the reaction being accelerated by incorporating a free-radical catalyst, e.g. benzoyl peroxide, t-butyl hydroperoxide, bis-cyclohexyl-azocarbonitrile, in amount 0,1 to 5,0% by weight of the rubber.  Sulphur dioxide liberating compounds, if used, may be pre-mixed with 1 to 5%, based on the weight of rubber, of inert fillers, e.g. silica, carbon black. Master batch techniques may be used.
Patent GB-1604531-A (GB)
Title: Interference suppression inductor for phase-controlled semi-conductor circuits
IPC: H01F17/06
Filed: 1978-05-12
Abstract: The radio suppression inductor consists of an annular core and of a winding (4), the annular core being assembled from two soft-magnetic metal-powder blanks (core elements 1, 2). One of the two core elements contains no insulating binding agent, while the other core element consists of a soft-magnetic metal powder and an insulating binding agent. The advantage of such a suppression inductor is, on the one hand, that the two core elements can be produced using the conventional pressing process for moulded cores and, on the other hand, that suppression circuits can be constructed using it, in the case of which fast switching-on processes do not exceed the required interference level. <IMAGE>

Abstract: 1,038,101. Cartons. BEMROSE & SONS Ltd., and D. A. MORETON. May 14, 1963 [May 21, 1962; May 30, 1962], Nos. 19521/62 and 20912/62. Heading B8P. To eliminate pin-holes at at least six corners of a carton formed from a single blank, the blank is provided at each side with three triangular gussets 19, 20 and 21 joined to one another and to the back wall 18 and the side walls 7 and 13 respectively, and also with a pair of gussets 15 and 16 between the lid panel side wall 13 and front wall 14. The tray front wall 10 is bevelled at its side edges for insertion on erection of the box between the lid front wall 14 and the pleat formed by gussets 15 and 16 (see Fig. 2, not shown). The three triangular gussets may be formed by cutting out a notch 34 (Fig. 8, not shown) and bulging, friction and binding on folding can be avoided by making the angle of the notch less than ninety degrees or by flaring the notch. The side walls overlap and the lid may be made to interlock in a slit in the tray front wall, or the carton may be secured shut along one or more sides. To enable the lid to clear the front top corners of the side walls 7, the gussets may be modified (Fig. 9, not shown) by giving the crease between the gussets 8 and the side walls 7 a fall back angle p. A thermoplastics coating may be applied to part or all of the blank and the closure made by application of heat and pressure.

Title: Improvements in electrical apparatus for signalling information relating to trains or the like
IPC: B61L25/04
Filed: 1928-10-08
Abstract: 327,944. White, A. E., (Godfree, E. G.). Oct. 8, 1928. Selective, signalling-apparatus.-In a signalling system for indicating the progress of a number of trains or the like over a section of track, signals relating to successive trains on the section are successively indicated on a plurality of stepby-step indicators and a lamp associated with the indicator recording the first train on the section is illuminated. ' As shown in Fig. 1, impulse senders, each adapted to transmit a code charac.- teristic of a train and comprising contacts 7, 8, 9, are connected over three line wires (an earth return may be employed if desired) to a relay 22 and the stepping magnet of a selector switch 28. Upon operation of an impulse sender, closure of contacts 7, 8 advances the selector 28 one step to switch into circuit an indicator in the group 12 - - 12<c> and impulses generated by contacts 8, 9 operate relay 22 to cause impulses of alternate polarity to operate the selected indicator. A further signal relating to the next train on the section -operates the next indicator in the group and so on. In this manner, successive signals are recorded on the indicators in cyclic order. Upon the transmission of each signal, selector 28 operates an audible alarm 31. Associated with the indicators is a plurality of lamps 32 - - 32<c> operated through corresponding relays 13 - - 13<c> by plugs and jacks 14 - - 14c. The trains are disposed of in the sequence in which they are indicated so that assuming the indicator 12<a> signals the " first " train on the section, and the indicators 12<b> 12<c>, 12 in the order named indicate further trains, cancellation of the " first " indication is effected by inserting a plug 33 in jack 14a to complete a circuit through coil 21 and the cancelling key 15 and simultaneously illuminate lamp 32<b> corresponding to the next indication which then relates to the first train on the section. Operation of the key 15 effects restoration to normal of the indicator 12a. Construction of indicator. Each indicator comprises a pointer mounted on a shaft 17 which is driven against spring control by a pawl and ratchet mechanism 19, 18. The pawl 19, is carried by a pivoted lever 19<a> which is operated by a lever 20<a> on the armature 20 of the electromagnets 21. The lever 20<a> carries two pins 20<b>, 20<c> which function to produce operation of the pawl 19 irrespective of the polarity of the operating impulse. The shaft 17 also carries a member 18b provided with pins 18<a> adapted to co-operate with a retaining pawl 16<b> the arrangement being such that the indication is displayed only by transmitting a predetermined number of impulses. An incorrect number of impulses would result in the restoration to normal of the indicator. Impulse senders. Each impulse sender comprises a code disc driven through gearing by a spring which is tensioned when the sender is operated.

Abstract: 359,965. Discharge lamps. WHITE, A. E., 5, Quality Court, Chancery Lane, London.-(Flexlume Corporation; 1100. Military Road, Tonamanda, New York, U.S.A.) June 30, 1930, No. 19822. ,Class 39 (i).] In alternating- current, positivecolumn, discharge tubes with an electrode at each end of a long tube 1, Fig.1, a hollow electrode 4, such as a cylinder open at both ends, is surrounded by, and contacts with, a hollow insulating body 5 defining a restricted or obstructed discharge path between the interior of the electrode 4 and the tube 1, this path being of less cross-sectional area than the main illuminating part of the tube 1, The obstruction is preferably an end 9 of internal diameter less than that of the electrode 4 but may alternatively be a cap 10, Fig. 3, with apertures 11 for the discharge. Disintegration of the electrode on to the tube 1 and absorption of gas thereby is thus avoided. The body 5 may be of glass and the electrode of foraminous material partially embedded in the glass to increase the flow of heat from the electrode. The body 5 may be supported by a flanged glass cylinder 7 or a glass sleeve 12, discharges to the lead 3a at the back of the body 5 being avoided in both constructions. Dischares to the lead inside the are avoided by offsetting the lead as shown into a position not in the axial centre of the discharge. Dimensions of the electrode structure, when the tube 1 is filled with neon at 8-10 mm., are given.

Title: Improvements in the manufacture of ketene, acetic anhydride or a homologue thereof
IPC: C07C51/56
Filed: 1936-07-17
Abstract: Acetic anhydride, ketene, and their homologues are produced by the thermal dehydration of an aliphatic acid in the presence of a phosphine, a tetraphosphonium base or a salt thereof, or a triphosphine oxide.  The phosphine derivatives may contain as substituents methyl, ethyl, phenyl, p-tolyl, benzyl &c.  These catalysts may be used together with nitrogenous bases such as those mentioned in Specification 317,907, [Class 2 (iii)].  They may be dissolved in the main bulk of the acid to be treated or may be injected into the reaction chamber separately, or separately from the main bulk of acid; the catalyst may be dissolved in a portion of the acid to be treated, or in another solvent, which may be one that will facilitate the separation of the products for instance by forming an azeotropic mixture with water.  The anhydride or ketene may be separated in any suitable manner; for example the reaction vapours may be condensed to liquefy water, acid, and anhydride and allow the ketene to pass on, or it may be fractionally condensed to separate the anhydride from water and ketene; in the latter case it is preferred to employ liquids such as benzene, toluene, xylene, chlorbenzene, chloroform &c. which form azeotropic mixtures with water.  Other acids the treatment of which is mentioned are propionic and butyric acids.  Specification 280,972, [Class 2 (iii)], also is referred to.

Abstract: 882,160. Magnetic tests. COMPAGNIE DE SAINT-GOBAIN. June 7, 1960 [June 6, 1959] No. 20016/60. Class 37. [Also in Group XXIII, Glass sheets are marked where required to be cut and the marks sensed automatically to operate a device which scores the glass. The marks may be opaque and sensed photo-electrically, or electrically conducting or permanently magnetized and sensed accordingly, or may project from the surface and be sensed by a feeler. The marks, which may be in the form of adhesive strips, are applied as the glass is passed, in a vertical position, in front of an operator. The sheet is then placed on a table formed by rotating rollers 5 which move it past the photo-electric or other appropriate sensing device 8 which detects transverse marks and causes a device 10 moving on a transverse guide 7 to score the glass when marked. The guide 7 is angled and the speed of the device 10 related to that of the rollers 5 so that a transverse mark is made. A roller on a pivoted arm 18 then bears on the sheet 1 as it passes from the rollers 5 to a conveyer 20 at a slightly lower lever and severs it where scored. The severed portions 1a are then picked up in turn by suction pads on a conveyer 22 moving on rails 21 and placed on a table formed of rotating rollers 24 and having a sensing device and a device 25 for scoring the marks in the longitudinal direction of the original sheet. The glass may be scored to a shape determined by a template instead of in straight lines.

Filed: 1974-05-07
Abstract: 1469956 Determining particle sizes in suspensions BAYER AG 7 May 1974 [15 May 1973] 20025/74 Heading G1S A suspension in a supply vessel 2 is injected into one or both rotating vessels 8, 9 via nozzles 3, 4 and is centrifuged by a rotating shaft 1 and telescopic shafts 21, 22. Floats 18, 19 which immerse deeper as the test proceeds, partly compensate by their buoyancy forces for the centrifugal force of the suspension particles depositing on settling plates 14, 15 and the floats move radially of the shaft 1 on the telescopic shafts 21, 22 sliding in magnetic or air bearings 23, 24 the time for settlement on the plates being representative of the range of sizes of the particles. In the inoperative position, the plates are pulled inwardly by a spring 20 to abut against the bottoms of cylinders 8, 9 and are held thus by a pin 26 passing through two slots 27, 28. This occurs whilst the rotor is running and prevents the liquid when injected from penetrating below the settling plates. The plates are released for testing by withdrawing the pin 26 after injection. During operation, settlement on the plates 14, 15 causes the shafts 21, 22 to slide relatively to one another and operate a capacitive, resistive or pneumatic displacement measuring system 29. The displacement of the pins 29 is brought about by injecting more liquid for example into one side than the other, so that more particles are deposited on that one side and an unbalance of the shafts 21, 22 introduced which causes them to move axially and move the pins 29 relatively to one another to give a reading. The displacement amounts to about 200um and is a measure of the mass of sediment deposited, the rate of deposition being related to the particle size. The rotational speed may be constant or variable and one of the vessels 8, 9 may be filled with pure liquid.
