Title: Improvements in or relating to recording apparatus
IPC: H04M1/56
Filed: 1961-09-20
Abstract: 938,499. Impulse transmitters. HASLAR A.G. Sept. 20, 1961 [Sept. 21, 1960], No. 33684/61. Class 40 (4). In apparatus for indicating the digit last dialled, the indicating mechanism is returned to zero on commencement of the following dialling movement by a heart-shaped cam and spring loaded follower arrangement so that the indicator returns to zero by the shortest route. In the described embodiment the dial finger plate is coupled via gears 12 and 14 to a gear 15 carrying an actuating arm 16. At the start of a dialling operation, arm 16 moves in the slot in member 20, which is frictionally mounted on stationary shaft 27, and depresses end 25 of pawl 22 to release plate 30 which together with indicator disc 32 is returned to zero by the action of spring loaded arm 41 on heart shaped cam 31. Further movement of the dialling mechanism rotates, via the gear train and actuating arm 16, the member 20 and the pawl relative to disc 30, until the selected number hole on dial plate 10 is adjacent finger stop 11. Return motion of the dial initially causes arm 16 to move in the slot in member 20 to the position shown, thus engaging pawl 22 with a slot in disc 30, further motion of the dial back to its rest position results in disc 30 and indicator 32 rotating until the appropriate number shows in aperture 44.

Title: Improvements relating to electric relays
IPC: H01H47/22
Filed: 1933-12-02
Abstract: 419,564. Electromagnetic switches. BRUSH ELECTRICAL ENGINEERING CO., Ltd., and MESSENT, J. S., Falcon Works, Loughborough, Leicestershire. Dec. 2, 1933, No. 33935. [Class 38 (v).] In order to ensure that a relay shall be operated correctly with small changes in the applied voltage a baretter is connected in series with a capacity or reactance across the circuit carrying the actuating voltage to fluctuation of which the relay is intended to respond, the relay magnet coil being connected in parallel with the baretter. As shown the baretter 4, which may consist of an iron wire resistance in a hydrogen atmosphere, is placed in series with a condenser 5 across the supply, the energizing winding 2 of the relay being shunted across the baretter terminals. The automatic variation of the resistance of the baretter thus causes relatively large changes in the voltage across the relay 2 with relatively small changes in voltage in the supply circuit thus making the relay extremely sensitive to variations of voltage in the supply. A resistance 3<a> is included in the shunt circuit containing the relay winding to compensate for the inductance in the winding itself or alternatively this may be effected by feeding the relay coil in the shunt circuit through a copperoxide rectifier bridge (Fig. 4, not shown). Instead of a condenser a reactance may be employed in series with the baretter so that the voltages across the baretter and across the series impedance are approximately in quadrature.

Title: Bottle Capping Device
Inventor: EDWARDS JOHN HENRY
IPC: B67B5/00
Filed: 1966-07-28
Abstract: 1,172,081. Capping bottles. VISCOSE DEVELOPMENT CO. Ltd. 28 July, 1967 [28 July, 1966], No. 33964/66. Heading B8T. An elastic capsule 7 is applied to the neck of a bottle 8 by means of springs 5 mounted on a ring 4, the capsule being supported by fingers 5b of the springs 5 and stretched when the springs 5 move down over the neck and meet the shoulder of the bottle, further downward movement causing the fingers to disengage from the capsule and move radially outwards. The springs 5 are reciprocated vertically by means of a ram 1 operated by mechanical or fluid pressure. A hollow section 2 has an open side 3 through which capsules are fed, e.g. by automatic means, when the springs 5 are raised above the bottle neck, Fig. 1 (not shown). A fixed ring 6 constrains the springs to bring the fingers 5b below the capsule. The ram then lowers the capsule into position on the bottle neck. The springs 5 may be steel and be modified to co-operate with bottle necks of different shape, Fig. 7 (not shown); or they may be pivoted on the ring 4, their upper part being formed in a vertical plane normal to that of their respective fingers (5b), Fig. 8 (not shown), and outwardly sprung by means of a pad (9). Alternatively, Fig. 9 (not shown), a hollow plunger (11) slidable coaxially with the hollow section (2) has an abutment (11a) which forces the springs 5 outwards, as the ram 1 descends, against the restraining action of a rubber band (10) encircling the lower ends of the springs.

Abstract: 871,641. Radar. GENERAL MOTORS CORPORATION. Oct. 8, 1959 [Oct. 29, 1958], No. 34120/59. Class 40(7) Means for indicating to the driver of a first vehicle when it is safe to pull out into the path of an approaching vehicle in order to overtake slower vehicles ahead comprises means on the first vehicle for computing the time to collision with the approaching vehicle and the time to pass the vehicles ahead, a visual indication being given when the time to pass is less than the time to collision by a predetermined margin. As shown the narrow beam of a radar 16 on the first vehicle 12 is directed at the approaching vehicle 14 and the reflected signal is mixed with the transmitted signal to give a beat frequency signal whose frequency is proportional to the closing rate of the two vehicles and whose amplitude rate of increase as determined by a circuit 26 is a function of the distance between the two vehicles, the time to collision being derived therefrom in a computer 30. In order to eliminate signals due to stationary objects and vehicles travelling in the same direction the beat frequency signal is passed through a high-pass filter 22 whose cut-off frequency is controlled by the speedometer 24. The time to pass the vehicle ahead is evaluated in a computer 38 as a function of the number of vehicles ahead as set in by a manual control 42 and the available acceleration at the present speed which is evaluated in a computer 34 controlled by the speedometer 24. When the time to pass is less than the time to collision by a predetermined margin as determined by a comparator 44 a red light 46 is extinguished and a yellow light 48 is switched on.

Title: Improvements in or relating to the separation of the constituents of organic-inorganic addition compounds
IPC: C07C51/487
Filed: 1936-12-11
Abstract: An organic compound is separated from its addition compound with an inorganic compound by reacting with an anhydrous organic addition agent which forms an addition compound with the inorganic compound or reacts exothermically therewith.  The organic compound can be recovered, for example, by distillation, absorption or extraction. Addition compounds of aliphatic acids, e.g. acetic, propionic, and butyric, ethers, esters, ketones, amines, and amides with inorganic halides, e.g. halides of Al, B, Sn, Be, Ti, Si, Zr, Hf, Th, Cb, P, Cr, W, S, Ca, Ba, Sr, and Ta, are referred to.  Dimethyl ether can be recovered from its addition compound with boron fluoride by adding methyl acetate and distilling off the ether.  Alternatively, since the methyl acetate addition compound has the lower boiling point, by regulating the reflux methyl acetate can be recovered therefrom by distilling during continuous addition of methyl ether.  In examples: (1) methyl acetate is added to (CH3)2O.BF3 and the ether distilled over at 38-40 DEG  C.; (2) propionic acid is added to CH3COOH.BF3 and the mixture distilled at about 27 mm. and 32-35,5 DEG  C., pure acetic acid coming over.  The Specification as open to inspection under Sect. 91 gives equations for reaction of the addition compound with water to recover the organic compound which may be an alcohol, and for reacting a BF3-water complex with acetic acid which displaces the water.  An additional example describes the treatment of BF3.H2O with ethylene at elevated temperature and pressure.  A CO pressure of 600-900 atm. is imposed and the mixture heated to 175-180 DEG  C. The reaction product gives off some BF3 on heating and on injecting steam gives an aqueous propionic acid condensate leaving a residue of BF3. 2.3-2.5 H2O.  A further example describes the formation of a complex by heating CH3OH, BF3, and H2O at 230 DEG  C. and 850 atm. CO pressure.  The product is distilled while adding water, acetic acid coming over.  This subject-matter does not appear in the Specification as accepted.

Title: Knitting machine
IPC: D04B15/00
Filed: 1956-11-08
Abstract: 803,181. Knitting. SOCIETE DE L'USINE DE LA MARQUE. Nov. 8, 1956 [Nov. 8, 1955; Nov. 2, 1956], No. 34167/56. Class 74 (2). A grid of a material having characteristics which, especially as regards hardness and coefficient of friction, are substantially the same as those of the material of which the needle butts are made, guides the butts by reason of apertures aligned with the tricks of the needle bed, which bed is of a material such characteristics of which are substantially different from those of the butts. In the form of Figs. 2 and 4, the grid 13, made of a material (e.g. steel or bronze) having a hardness and a coefficient of friction of the same order as those of the needles, is secured to the needle bed by, at one end, a bar 9 recessed in a transverse slot in the bed, a clamp 11 and a screw 12 and, at the other end, a wedge 15 and a slot 14 in the bed. The needle bed itself may be of, say, a polyvinyl resin, polythene, a superpolyamide, an aluminium alloy or light metal, a copper alloy or wood; it is made up of elements 1, each provided with two rabbets, so that when the elements are bolted or cemented together each pair of contiguous rabbets forms a needle trick. Such trick emerges on one longitudinal face 3 of the needle bed, but stops short of the opposite face thereof, where each element has a projection 5 within which a unit of the slot 14 is formed. The needles slide with slight play in the tricks and bear against a cord 8 of felt or similar material, against which they are held by the bar 9. A rod 18 normally engages with a bend 19 in each of the needles, to hold them retracted. The cam carriage slides against the external face of the grid. In the modification of Fig. 5, the grid 13a is bent over along a line so positioned that, when the grid is secured to the face of the needle bed, the ends 22 of the apertures in the grid stand slightly proud of the bottoms of the tricks 2 of the bed. This bent-over end of the grid engages in a groove 25 in the bed and is secured in position by clamping jaws 26. Facing the cord 8 of felt or the like are two needleretaining strips 28 of steel, or the like arranged end to end in a dovetail recess in the bed such strip may be provided with a knob 29 serving as a handle and as a positioning abutment; and after sliding the appropriate strip out of the way, any needle may be removed without removing the grid. There are also provided a cam carriage guide 30, needlepositioning rod 18 and the coacting bends 19 in the needle stems. The needle bed may be in one unit or formed of juxtaposed elements, in which latter case the elements are aligned by a strip 27 of, say, steel, dovetailed into the rear end 24 of the bed.

Abstract: 901,904. Photo-cell arrangements. BALDWIN PIANO CO. Oct. 5, 1960, No. 34175/60. Class 40 (3). [Also in Group XXXVI] A photo-sensitive device comprising a pair of spaced electrodes interconnected by photoconductive semi-conductor material is provided with an element connected across the electrodes to limit the potential that can occur across the device. This is particularly necessary where the electrode spacing is very small. In one embodiment, using a plurality of devices in an arrangement that could form part of an optical encoder, all the devices are constructed on a common insulating base 14 which may be glass. Two groups of confronting electrodes 16 and 18 formed of electrically conducting films are disposed on opposite sides of a common axis. The spacing between pairs of electrodes may be of the order of four microns and electrodes 18 are interconnected by bar 20. A ribbon of photo-conductive material 22 covers the gaps between the pairs of electrodes. In use such a construction is used with a sequential pulse generator 24 applying pulses to electrodes 16 in sequence through resistors 28. Each electrode 16 is also connected to earth through a resistor 30 and the joined electrodes 18 and earthed through a resistor 34. Illumination of one or more of the devices results in a pulse or pulses being passed at corresponding times in the pulse generator cycle to amplifier 32 and thence to utilization means. According to the invention, an element 36 is provided to limit the potential across the devices. This may either be a pair of spaced electrodes arranged to break down prior to ribbon 22 or a Zener diode. Specification 875,953 is referred to.

Headings G1M and G1N. In apparatus for examining the surfaces of the curved tracks of the race rings of a ball-bearing, the outer ring 12 is suspended on a knife-edge support 3 having a curvature complementary to that of the track 13, and is rocked in the plane of the support 3, surface roughness being detected by a feeler 8 connected to an electrical transducer 7; the inner race ring (not shown) is similarly examined on a lower support 4. To rock the ring 12 across the support 3, a knife-edged bar 5 is pushed against the ring by a descending weight 16 acting through a plunger 11 and a spring-loaded piston 19 in a cylinder 20; a wedge 21 is moved by the piston 19 to displace a roller 22 and thus move a slide 6 carrying a pillar 5a on which bar 5 is mounted. The speed of descent of weight 16 is controlled by a hydraulic damper 18, and stop members 5b on bar 5 prevent ring 12 from swing- ing in a direction normal to the support 3. Transducer 7, which comprises a ferrite plunger cooperating with an inductance coil, is used to vary the frequency of an oscillator, indication being by means of oscilloscope or graphic recorder. Two annular ferrite magnets in the transducer serve to damp the vibrations of the feeler 8.

Abstract: 1279101 Variable pitch propellers DOWTY TECHNICAL DEVELOPMENTS Ltd 1 July 1970 [8 July 1969] 34258/69 Heading B7V [Also in Division F1] In an aircraft propeller the blades 27 mounted in a hub of a rotor are angularly adjustable for pitch, twist or camber about their longitudinal axes 35 by a fluid-pressure-operable motor having an element or plate 44 movable linearly and angularly with respect to the hub and being coupled to each blade by a respective link 67 having a pivotal connection at one end portion and a universal connection at the other end portion. The plate 44 has a cylindrical member 46 extending forwardly through an aperture, including a fluid seal 37, into a domed cylindrical casing 40, and a rearwardly extending cylindrical member 48 sealingly connected to a tube 50. Fluid under pressure is delivered under the control of a manually operated valve (not shown) through the tube 50 to cause displacement of the plate 44 to the right so that the links 67 pivotally connected thereto angularly adjust the blades 27 about their longitudinal axes 35. The movement of the plate 44 towards the right, i.e. the pitch-fining direction, is performed against a spring 56 and also against the effort of balancing weights 65 which bias the blades in the pitch-coarsening direction. The spring 56 bears at the other end against an annular flange member 52 which is free to move angularly with respect to the hub by means of a roller bearing 53. An auxiliary spring 59, stronger than the spring 56 also seats against the member 52 and encounters the plate 44 when the blades 27 move into a reverse pitch position and a sleeve 62 limits the extent of rearward movement of the member 44. The fluid motor may alternatively be double acting and may also be of the movable cylinder type.
