Title: Improvements in or relating to devices for digital measurement of the displacement of an object
IPC: G01D5/38
Filed: 1961-06-22
Abstract: 940,167. Selective signalling systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 22, 1961 [June 25, 1960], No. 22658/61. Heading G4H. In a displacement-measuring system, an interference pattern is derived from a movable grating, an image of a grating on a continuously rotated drum is superimposed on the interference pattern, and the resulting light fluctuations are compared in phase with an alternating signal derived from the drum grating. In a first embodiment, Fig. 2, movable grating 13 co-operates with a fixed grating 14 having a different line-spacing or being slightly inclined relative to grating 13, to produce the interference pattern. The axes of lens systems 5, 6, 15 are inclined to gratings 13, 14 so as to utilize the first order diffraction maxima. The fringe spacing of the interference pattern is equal to the line spacing of the drum grating 4. The alternating signal is derived from grating 4 by means of a fixed grating 9, and the phase relationship between the signals from photo-cells 3, 11 represents the direction and extent of movement of grating 13. Three other methods of producing the interference pattern are described. In one method, Fig. 3 (not shown) grating 14 comprises two vertically separated portions respectively having q lines per inch more than and less than grating 13 so that two sets of MoirÚ fringes are produced, these fringes moving in opposite directions as grating 13 moves. Drum grating 4 is imaged on both sets of fringes and the signals derived from two associated photo-cells contain the desired phase information. This system is twice as accurate as that shown in Fig. 2. In another method, grating 14 is again replaced by two vertically separated gratings, but the lines of these gratings have equal spacing and are oppositely inclined to the lines on grating 13. In the system of Fig. 5 the interference pattern is produced by reflecting the image of grating 13 on to itself, the zero order diffraction maximum being suppressed. A parallel-sided plate of glass 19 is placed in front of the lower half of grating 13 to suitably refract the light rays so that two sets of oppositely movable fringes are produced, photo-cells 3<SP>1</SP>, 3<SP>11</SP> deriving the corresponding signals. This system is shown to be eight times as accurate as that of Fig. 2.

Patent GB-1283353-A (GB)
Title: Article vending machine
Inventor: JENNINGS HENRY GEORGE FREDERIC
IPC: G07F11/72
Filed: 1968-05-14
Abstract: 1283353 Article dispensing apparatus HGF JENNINGS 14 Aug 1969 [14 May 1968] 22833/68 Heading A4T [Also in Division G4] A coin-freed vending machine for confectionary delivers one article 13 at each operation, and randomly delivers one or more additional articles depending on the positions of rotatable wheels 30. After coin insertion at 47, a handle 44 is rotated to move a plunger 45 to the right, an attached pin 54 serving to rotate a first arm 53 and its supporting shaft 52 clockwise. A roller 56 rigidly attached by a second arm 55 to the shaft 52, pushes to the right an arm 26 depending from an article delivery slide 21. An aperture 71 in the depending arm 26 passes over a roller 66 on a rocker arm 65, which then rotates so that roller 66 holds the slide 21 in its right most position, where it receives an article 13, from a hopper 12, see Fig. 4 (not reproduced). Simultaneously, shaft 52 rotates a third arm 57 to raise a piston 58 in a cylinder 59. Additionally, a rack 48 supported by the plunger 45 rotates clockwise a ratchet 38, while a pawl 36 rides freely. When the handle 44 is released, the plunger 45 returns to the left under spring action, and the attached rack 48 rotates the ratchet 38 anticlockwise, the pawl 36 serving to rotate simultaneously a cam disc 32 and attached wheel 30. The wheel 30 and cam disc 32 continue to rotate by inertia after the plunger 45 has reached the limit of its travel. Meanwhile, the piston 58 descends slowly, simultaneously rotating the shaft 52 and the attached three arms 57, 53, 55, until the second arm 55 rotates the rocker arm 65 so that the roller 66 again passes through the aperture 71, to free the depending arm 26 and slide 21 for spring-urged movement to the left. Eventually, a roller 29 mounted on the slide 21 enters between two pins 42 abutting from the wheel 30, to stop the rotation of the wheel 30 and cam disc 32. If the roller 29 co-operates with a notch 43 in the cam disc 32, the slide 21 moves to the left a distance to drop the entrained article 13 into a delivery channel 16. If the co-operation does not occur, see Fig.1, the slide 21 is stopped short by the cam disc 32, and the entrained article 13 is retained by a block 20. Shaft 31 supports a plurality of axially spaced wheels 30 each co-operating with a delivery slide 21, a plunger 65 and a second arm 55. At least one of the wheels 30 does not support a cam disc 32, so that the associated delivery slide 21 delivers an article 13 at each machine operation. The slides 21 for delivery additional articles may be replaced by a simple slide carrying a plurality of rollers 29, extra articles being delivered only when all rollers 29 co-operate with respective cam disc notches 43. Hopper 12 may be divided into separate hoppers for each slide 21. The wheels 30 carry numerals, see Fig. 2 (not reproduced), visible to a machine operator.

Title: Improvements in digital-to-analogue converters
Inventor: MYNALL DENNIS JAMES
IPC: H03M1/00
Filed: 1957-07-19
Abstract: 821,187. Digital to analogue converters. BRITISH THOMSON-HOUSTON CO. Ltd. July 19, 1957, No. 22967/57. Class 40 (1). A digital to analogue converter has a number of switches to which the digital values are applied, the switches governing the interconnection in a network of admittance elements all having the same electrical phase angle and a circuit connected to the network presenting to it a predetermined " negative admittance " (as defined below) such that the current in the circuit is closely proportional to sin (a + #) or cos (a + #), where α is proportional to the value of the digital input and # is a constant. A negative admittance is an element of fixed value having an electrical phase angle differing by 180 electrical degrees from that of the other admittance elements. The admittances may be resistances and the negative admittance may be provided by a high gain amplifier 10, Fig. 6, which has a positive feedback to terminal B. The switches controlled by the digital input separate the admittances in the network into two groups of parallel connected resistors A and B connected in series at a central point C. The circuit is supplied with a voltage source E and the current flowing depends upon the distribution of the admittances between groups A and B. This current is the analogue required. The input also controls a reversing switch 12 for inverting the sign of the output. Resistors 14, 15 and 16 govern the operation of the feed-back. The amplifier supplies an output to the load 11 which is the utilization device, the current in which is proportional to the digital input value as set out above. In Fig. 7 the outputs from a circuit 17 connected to produce a sine value and a circuit 18 producing a cosine value are applied to the windings 19, 20 of a resultant field apparatus to control a rotary or linear motion. In the circuit a source of A.C. 21 supplies both circuits. Circuit 17 has a switching network 22 dividing the available admittances into two groups, an amplifier 10 with feedback and control resistors 23, 24, 25. The output passes through the sign inverting switch 26 to quadrature winding 19. The circuit 18 is similarly arranged. Capacitors 27, 27<SP>1</SP> connected to a supply in antiphase to the circuit voltage compensate for capacitative effects in the switches of the networks. Capacitors 28, 28<SP>1</SP> compensate for capacity effects at the inputs to the amplifiers. The mathematical basis of the invention is developed in the Specification.

Filed: 1955-08-10
Abstract: 787,484. Compression-moulding of ceramic material. BUHLER, GEB. Aug. 10, 1955 [Aug. 11, 1954], No. 23074/55. Class 87(2). In a process for electrically loosening ceramic pressed articles from a plurality of co-operating deformation tools the loosening of a pressed article from at least the deformation tool which is loosened lastly from it takes place in a period during which no more deformation occurs and during which at least two deformation tools are still in close contact with the pressed article. The loosening is accomplished from a deformation tool or half-form by applying a negative voltage thereto, a positive voltage being applied to the co-operating tool or half-form. The ceramic material is pressed between a deformation tool or half-form 7 and one of a series of half-forms 9-13. The vertically movable head 1 on which the half-form 7 is mounted, insulated from it, is forced downwards by a cam 3 engaging a roller 5 on the head 1 and is returned upwards by a mechanism not shown. The camshaft 4 drives a shaft 14 through a Geneva wheel, whereby a drum 8 is driven step by step and brings the half-forms 9-13 in succession beneath the half-form 7. As the cam 3 revolves in the direction indicated the material is pressed and deformed between the half-forms 7 and 9 until the point 18 on the cam periphery reaches the roller 5 ; from 18 to 19, pressure is relieved to allow de-aeration ; from 19, pressure rises to a maximum at 20; and the periphery 20-21 is circular, resulting in a period of constant pressure. After 21 the cam periphery is such as to allow the return mechanism to raise the die 7. A negative voltage to release the pressed article from one of the half-forms may be applied thereto while the pressure is increasing or during the period of constant pressure (as illustrated in diagrammatic examples), but negative voltage is only applied to the other half-form during the constant pressure period, i.e., when no further deformation of the material is occurring and while the half-forms are still in contact with the pressed article. The voltage is applied and removed at the required instance by a switch actuated by a cam on the shaft 4.
