Title: Improvements relating to electrical function generators
Inventor: PERCIVAL WILLIAM SPENCER
IPC: G06G7/28
Filed: 1963-11-15
Abstract: 1,105,312. Function generators. ELECTRIC & MUSICAL INDUSTRIES Ltd. 16 Nov., 1964 [15 Nov., 1963], No. 45136/63. Heading G4G. In an electric analogue function generator (Fig. 1), three inputs 1, 2, 3, are respectively connected to columns of six resistors 5A, 6A, 7A, 8A, 9A, 10A; 5B, 6B, 7B, 8B, 9B, 10B, 5C, 6C, 7C, 8C, 9C, 10C; of which the A, B, C, rows are returned respectively to conductors 5, 6, 7, 8, 9, 10. Conductors 5, 6 are connected through cathode-anode paths of diodes 11, 12 to a positive source of current 2i from source 19, which together with conductors 7, 8 is connected through anode-cathode paths of diodes 13, 14, 15 to a negative source of current 2i from source 20. The latter connection is taken together with conductors 9, 10 through cathode-anode paths of diodes 16, 17, 18 to a positive source of current i from source 21 and to output terminal 4. Low impedance voltages are applied to terminals 1, 2, 3, and resultant voltages in conductors 5, 6. . . 10 represent linear functions of the input voltages determined by the values of the several resistors and approximating to sections of a required non- linear function. E.g. if resistors 5A, 5B, 5C have values R A , R B,  K C  respectively and voltages V 1 , V 2 , V 3  are applied to terminals 1, 2, 3 the composite voltage on line 5 will be The potential at 19 then rises until one of diodes 11, 12 conducts, and holds the lower potential of lines 5, 6. Similarly, the potential at 20 falls until one of the diodes 13, 14, 15 conducts, and holds the highest potential of lines 19, 7, 8. The output 21 also holds the potential of the least potential of lines 20, 9, 10. If inputs V 1  are applied to terminal 1, constant k to the terminal 2, and zero to terminal 3, the potentials of conductors 5 to 10 represent linear functions p5 to p10 against V as abscissa (Fig. 2) intersecting at points A to E, and it is shown that V 0  as ordinate is represented by solid lines comprising a piecewise-linear synthesis of a required function. In a modified diode arrangement (Fig. 4, not shown) lines 5, 8; 6, 7: 9, 10 are connected in respective pairs over the anode-cathode paths of corresponding diodes to distinct negative current sources - 2i, and through the cathode-anode paths of other corresponding diodes to the output terminal and a positive current source i. The resultant output voltage to input voltage graph (Fig. 3, not shown) represents a piecewise-linear synthesis of a required function, as in Figs. 1, 2 above. A first-function generator h, = # may be connected in tandem with a second function generator of h = h<SP>2</SP>/C to produce the function h = ab/C.

Title: A conveying device
Inventor: DAVIDSON MATS INGE
IPC: B65G19/02
Filed: 1968-09-24
Abstract: 1,249,995. Conveyer systems. M. I. DAVIDSON. 24 Sept., 1968 [27 March, 1968], No. 45365/68. Headings B7L and B7N. In a conveying system, carriers 34 are conveyed by dogs 3 which extend upwards from a belt 1 which runs on edge in a slotted member 2 having a rounded upper surface which forms the running surface for the inner flanges 61 of the carrier roller assembly 60. The belt 1 is driven by sprocket wheels engaging holes 5 and the carriers are formed with depending fork-shaped legs 50, 51 with clamping means 55 for holding, e.g. a garment or the like. The carrier hub 63 carries an address member 65 including a number of elements which can be raised or depressed to define a work position address on a side track 32 off the main track 2. When a carrier held at a work station at stop 36 has to be sent to the next work position it is driven past addressing device 35, Figs. 15 and 16 (not shown), which sets up the required address as defined by buttons (87). At each of the subsidiary tube-shaped side tracks 32, forming part of a working station, carriers are removed from the main track by an unloading arm 33 and run under gravity to a stop 36. From the stop the carriers can be driven up to the main line entry position by a subsidiary reciprocating conveyer operated by hydraulic plunger means and including dogs 44, Figs. 6 and 7 (not shown, which are raised in the up stroke and lowered in the return stroke. Where one stroke is insufficient to move the carriers to the entry position, catch means 49 is provided for preventing carrier run back. When the carrier reaches the entry portion 38 it is held until detector means, Figs. 17, 18, 28, 29 (not shown) produces a release signal indicating the presence on the main line of a drive dog which is not preceded by a carrier. When a carrier addressed, e.g. by two raised address elements reaches the sensing device in advance of the loop to which it is addressed, the raised elements engage two similarly positioned sensing elements and thereby allow a member 140 to rotate clockwise moving an arm 141 into a detent on member 151. The roller elements on the carrier then engage member 142 moving arm 141 and hence member 151 and assembly 145, 146 to the left until rod 153 of the unloading arm swings down off the end of member 146 to pick up the carrier from the main line. The following main line dog engages a part of the arm, lifting it so that it resumes its position with its rod 153 supported on member 146. The following abridgments are included in this series since the Specifications were, through an error, not allotted to this Group. References to them will be found in the indexes to this volume.

Abstract: 1,127,893. Vitreous coating composition. BECKMAN INSTRUMENTS Inc. 27 Oct., 1965 [4 Nov., 1964], No. 45445/65. Addition to 1,002,791. Heading C1M. [Also in Division H1] A glass-metal electrical resistance material contains at least 50% and less than 84% of glass and from above 16% to 50% of an alloy of iridium with one or more of the metals platinum, rhodium and ruthenium. It is fired on to a non-conductive base, suitably of steatite, forsterite, sintered or fused alumina or zircon porcelain, at a temperature chosen so that the glass melts and the metal does not. Several examples of preferred combinations of glass and metals and compositions of suitable glasses are given. The glass binder, in the form of fine particles, is mixed with a resinate or organic compound solution of the metal or metals and heated to decompose the compounds. It is then ground, calcined for a short period and ground again to a fine powder, producing a dry material consisting of very small glass powder mixed with extremely small particles of metal. This may be stored. In use it is mixed with a suitable liquid carrier, applied to the base and fired to fuse the glass. Conductive electrodes may be added by applying a metal paste and firing to convert it to metal. Apparently the iridium in the metal phase prevents it from agglomerating, even when large amounts are present, so that the electrical resistance of the material is high in spite of its content of metal.

Abstract: 948,295. Fluid-pressure servomotor systems. BURNETT & ROLFE Ltd. Dec. 6, 1962 [Dec. 29, 1961], No.46665/61. Heading G3P. [Also in Division F2] A valve, for controlling the flow of beer in a pasteurizing apparatus, is opened by an electric motor and closed in response to a temperature or pressure signal from the beer in the apparatus. The valve closure 16 controlling flow from an inlet 7 to an outlet 2 is connected to a stem 23 having a rack 31 for co-operation with a pinion 30. The pinion 30 is fixed on a shaft 26 which is fixed axially with respect to a piston member 28 but is rotatable relatively to the piston. The stem 23 is also connected to a piston 34 working in a cylinder 33. In operation, the valve is opened by an electric motor 24 driving the shaft 26 through a clutch 25. If the temperature of the beer falls below a predetermined value, or the pressure rises above a predetermined value, a solenoid valve is operated to feed fluid to a chamber 41 thus moving the piston 28 to the left to disengage the clutch 25 and fluid is then fed through conduit 44, valve 45 and conduit 46 to cylinder 33 and the fluid acting on piston 34 causes closure of the valve. When the temperature or pressure reverts to the predetermined value, the cylinders 41 and 33 are exhausted and the clutch engages to open the valve through the motor. The valve 45 is such that it prevents flow to the cylinder 33 until the piston 28 has disengaged the clutch, but allows free flow in the reverse direction. Two such valves are preferably provided, one at each end of the apparatus in which one is responsive to temperature and one to pressure.
