Title: Improvements in or relating to apparatus adapted for heating the bottom of a lasted shoe
IPC: A43D25/20
Filed: 1950-05-17
Abstract: 700,678. Electric heating. BRITISH UNITED SHOE MACHINERY CO., Ltd., MOORE, A. E., and SMITH, F. R. May 15, 1951 [May 17, 1950 ; Dec. 14, 1950], Nos. 12281/50 and 30491/50. Class 39 (3) [Also in Group VII] An apparatus for heating the bottoms of lasted shoes comprises two assemblies A, A<SP>1</SP> pivoted together so that their inclination can be manually adjusted to the angular relationship between the waist and forepart portions of different shoe bottoms. The assemblies comprise heating sections P, Q, Fig. 9, and worksupporting sections R, S respectively, pivoted together at 19, 21. The heating sections comprise electrically heated thermostat controlled metal plates 23, 25, 27 and 45, 47, 49 secured to frames 29, 51 respectively and the work-supports comprise wires 41, 57 secured to frames 37, 53. The assembly A is fixed to a base 11. Bolts 71 secured to the frame 51 frictionally engage slots 73, 75 in side walls 13, 15 to allow the position of the assembly A' to be adjusted by movement of a bar 91 acting through bars 85, 86 and links 97, 99, 105, 107 connected respectively to frames 29, 51, 37, 53. The distance between the work-support and the heating sections can be varied since the pivots 21 are movable in slots 87 of the bars 85, 86. This is effected at any angular position of the assemblies by a handle 135 acting through a bar 129 and arm 127 and toggle links 117, 119 and 109, 111, the pivots 113, 121 of which are connected by a link 125. A shoe 147 is placed with its waist on the wires 41 and the assembly A<SP>1</SP> is adjusted so that the wires 57 engage the forepart. If it is desired to leave the shoes in position, damage can be prevented by raising the supports 41, 57 by the handle 135. In a modification, the distance between the worksupport and heating sections is fixed. Specifications 408,953 and 543,263, [both in Group VII], are referred to.

Title: Improvements in or relating to labelling machines
IPC: B65C3/16
Filed: 1951-05-25
Abstract: 687,452. Labelling machines. WEISS, J. May 25, 1951. [May 27, 1950] No. 12329/51. Class 73. [Also in Group XXX] Labels are applied to cylindrical articles which are conveyed through a machine into contact with a label transfer drum at which point they are rotated to apply the label. A suction transfer drum 4 removes a label from container 5, passes it over a gumming roller 7 into contact with the articles on the conveyer 2. A counter-bearing drum 8 is adjustably mounted on an arm 11 and resiliently held by a spring 12 against articles 3 on the conveyer. A star wheel 28 releases the articles in timed relation and the cylinder 8 is adjusted so that articles are held between adjacent rollers 9 which are freely rotatable on the cylinder 8. Hence by adjusting the speeds of the transfer drum 4, counter-bearing cylinders 8, and conveyer 2 the article is held in contact with the drum and caused to rotate about its own axis to strip a label from the drum. If the drum 4 is rotated in the opposite direction to that shown, the period of contact is longer and larger labels can be applied, and, to apply a label completely round an article, the cylinder 8 is rotated intermittently. A device 32 to prevent operation when no label is present can be provided.

Title: Improvements in devices for indicating or measuring the deviation of a movable surface from a reference plane position
IPC: G01P3/48
Filed: 1952-05-16
Abstract: 743,062. Photo-electric measuring systems. GIRERD, R. May 16, 1952 [May 18, 1951; Nov. 21, 1951], No. 12462/52. Class 40 (3) [Also in Group XXXVIII] The magnitude of a small movement produced by a thermal mechanical pressure &c. change on a surface is determined by its effect on the charge of a condenser whose one plate is linked to the moving surface, and the other plate is fixed, the charging rate being measured during the periodic closure of a switch for a time which is very short compared with the time to charge the condenser, causing the condenser to charge through a resistor whose potential drop is measured on a peak voltmeter. If the movement is an oscillatory one about a normal position the condenser will be continuously cha rged and discharged, so that the voltage across the resistor will continuously indicate the magnitude of the movement at the moments of closing switch. In one embodiment (Fig. 4) a capacitor 14 is connected in series with the varying condenser 1-2 through a half-wave rectifier 15, or as shown, a full-wave rectifier 15, 16, and the switching device is a photo-cell 12 periodically switched by an intermittent light beam 13, or by an intermittent spot on the screen of a cathoderay tube. The accumulated charge across capacitor 14 developed during the charging halfcycles of the movement of surface 9 and electrode 2 is proportional to the magnitude of the oscillation of the surface 9, and the number of complete cycles of oscillation of the surface 9 between the conductive instants of photo-cell 12, and is measured at 8 during the periodic discharge through resistor 7. The photo-cell and the rectifier may be amalgamated with the condenser 1-2 by coating the fixed electrode 1 with a layer 5 (Fig. 6) of selenium on iron, or copper oxide on copper. Alternatively, the layer of photo-electric material 5 may be placed on the surface of the moving electrode 2, and the fixed electrode 1 may consist of a semi-transparent film of metal on a transparent base 17 (Fig. 8). If the surface 9 is not itself conductive, a semi-transparent film of metal 18 may also be formed on the photo-electric layer 5. In a further embodiment (Fig. 9) the condenser electrodes 1, 28 are semi-transparent, semi-reflecting, conductive layers, so that if the light beam is monochromatic and not normal to the surfaces, internal interference occurs to amplify the light variation reaching the photo-conductive layer 5.

Patent GB-125165-A (GB)
IPC: G06G7/26
Abstract: 125,165. Wright, H. R. June 26, 1016. Calculating-apparatus; plane-trigonometry calculators.-For converting movements in accordance with a variable quantity into movements which are functions thereof, a potentiometer resistance is employed, the resistance of which varies per unit of length in the required manner. The resistance may take the form of a strip a of variable width through which passes a steady current from a battery b; a contact d moves in accordance with the variable quantity and is connected by wires l<1> with a galvanometer c, the readings of which give the required functions. Two such resistances may be employed to convert two quantities into functions and to combine these results. For indicating heights of bodies viewed through a range-finder e, Fig. 3, two resistance strips of circular form are employed. The movable contact of one is connected to the handle h for taking the range; the corresponding strip is so shaped as to transmit to the pointer s of a galvanometer r a movement representing the logarithm of the range. The movable contact of the other is connected to the handle g and moves in accordance with the angle of elevation, the strip being so shaped that the pointer o of a co-axial galvanometer n moves proportionately to the log sin of the angle of elevation. The height is found by turning the galvanometer r by worm gear from a handle q<1> until the pointer s registers with an index u carried by a fixed ring t, the result being read from the pointer o and scale v.
Patent GB-242223-A (GB)
Filed: 1925-05-14
Abstract: 242,223. Wolf, H. Nov. 3, 1924, [Convention date]. Hydrocarbons, cracking. - The products obtained in cracking hydrocarbon oils by heating under pressure, for example, by passage through a heated coil or a metal bath, are suddenly cooled immediately on their discharge from the cracking-apparatus to a temperature below 300‹ C. in order to prevent after reactions. The sudden cooling mav be effected either by direct admixture with a cooler oil or by spreading the products over a wide area of cooling surface. The pump P<1> Fig. 1, forces oil through a preheating coil 3 in an oil bath B and through a cracking coil 5 in a furnace F. The cracked products pass through a pressure-release valve 7 and are discharged through nozzle 8 into the oil contained in the bath B which may contain Rasohig rings. The mixture circulates up a pipe 10 against a baffle 11. Liquid drops back into the bath and vapours pass through a dephlegmator C and pipe 13 to a final condenser. The cracked products may be mixed with oil from the bath B passing through openings 9 or through a cock 15. Crude oil is supplied by a pump P<2> to the tank D receiving the condensate from the dephlegmator C and the mixture is passed into the bath B through a cock 16. The oil heated by admixture with the cracked products flows away through a pipe 14 to an oil-distillation apparatus. The cracked products may be suddenly cooled by being discharged through an expansion valve 26, Fig. 2, and a nozzle 27 below a plate 28 which distributes them over a cooler H, through which brine or oil cooled to a low temperature is passed. Specification 215,336 is referred to.

Title: Improvements in or relating to apparatus for transmitting signals to a vehicle driver
IPC: G08B1/08
Filed: 1945-05-18
Abstract: 594,336. Float-actuated, thermal, electromagnetic, and differential switches. GAGNAIRE, F. May 18, 1945, No. 12609. Convention date, April 4, 1944. [Class 38(v)] [Also in Groups XXXVIII and XL] Apparatus for transmitting to a vehicle driver signals received from a following vehicle comprises integrating apparatus subjected to a zeroing action and an indicating device set in operation when a sufficiently large number of signal impulses are received in a sufficiently short time. In the embodiment of Fig. 1, audible signals received by a microphone 1 and amplified and detected at 2, energise a relay 3 to close the circuit of a solenoid 5, whose core 6 is attracted and raises a ball 8 and an associated ball 9. During the time when a valve 10 is closed by neither ball a predetermined quantity of liquid is delivered to a tank 14 which has an adjustable outlet 16. When a sufficient number of signals is received by the microphone 1 in a sufficiently short time, the liquid delivered to the tank 14 exceeds the liquid escaping at the outlet 16 by an amount sufficient to raise a float 18 and close the associated contacts 19 to operate an indicator 20. The relay 3 may be made insensitive to signals of high frequency e.g. the vehicle's exhaust note by giving its armature a high moment of inertia, or by shunting a condenser 21 across the coils of the relay 3 so that for rapid signals the condenser 21 does not completely discharge and so provides a continuous current to keep relay 3 operated, or by providing a relay 3 of high reactance. The relay may be an alternating current type operated directly by microphonic currents. The receiver 1 may alternatively or additionally comprise a photoelectric cell sensitive to the headlights of a following car. Figs. 2, 5 (not shown) show integrating switch devices in which a pawl and ratchet in response to incoming signals stops a member against the suitablydamped return action of a spring. In a further embodiment, Fig. 6, the armature of the receiving relay 3<1> closes only momentarily contacts 3a which energise a solenoid 5 to raise a float 6 in oil or other liquid 42. The washer 43 allows unrestricted ascent but damped descent of the float 6. The hydraulic integrating device of this embodiment may be replaced by an electric condenser, Fig. 8 (not shown), or a hotwire switch, Fig. 9 (not shown). The indicator 20 may be provided with a locking circuit and with manual release means, the operation of which may also give a signal to the following vehicle.
