Filed: 1954-07-23
Abstract: 767,329. Date and time printing-apparatus. WALKER, J. V. July 22, 1955 [July 23, 1954], No. 21554/54. Class 100(2) In a date and time printing device, the impression hammer 5 is pivotally mounted beneath the type wheels 2 and is actuated by the closing of an electric switch when the paper to be printed is inserted in the device. The type wheels 2 driven by a mechanism 3 are mounted on the frame 4. The printing hammer 5 is pivoted on a bracket 6, carries a rubber impression pad 8, and is weighted at 7 and by an arm 9. On inserting paper or other similar material to be printed against a trigger lever 12, the latter through a trip lever 14 acts on a strip 21 to close a micro-switch 15, whereupon a solenoid 10 swings the hammer upwardly to print the date and time. An arm 20 on the solenoid acts on the lever 14 to release the strip 21 and open the switch. On removal of the paper, the levers 12, 14 return to their initial positions. The movement of the hammer 5 actuates by means of a link 23 spools 24 carrying an ink-ribbon passing across the type wheels.

Title: Electronic binary checking circuit injectable preparations
IPC: G01R31/28
Filed: 1973-05-07
Abstract: 1420787 Checking input codes INTERNATIONAL BUSINESS MACHINES CORP 7 May 1973 [20 June 1972] 21627/73 Heading G4H A binary code for checking that at least k out of n binary input variables are 1 comprises a circuit which is representable by the equation (c k,n ,d k,n ) = (a n e k,n-1 (a 1 ,a 2 , ... a n-1 ),a n e k-1,n-1 (a 1 , a 2  ... a n-1 )), where a 1  ... a n  are the input variables, e k,n  is an OR circuit receiving outputs from AND circuits, each of the AND circuits receiving k of the input variables, and wherein (c k,n , d k,n ) = (0, 1) or (1, 0) when at least k of the n inputs are 1, and (0, 0) otherwise. The terms c k,n  and d k,n  may be represented further as c k,n  = a n Àa 1 Àa 2 Àa 3  ... a k va n Àa 1 Àa 2  ... a k-1 Àa k+1  v ... va n Àa n-k  ... a n-1  and, d k,n  = a n Àa 1 Àa 2  ... a k-1 va n Àa 1 Àa 2  ... a k-2 Àa k v ... va n Àa n-k+1  ...a n-1  where "v" represents an OR function. As shown in Fig. 1, the arrangement when n = 4; k = 2 comprises AND gates 101-105 each receiving 2 of the inputs together with a 4  and supplying outputs to OR gate 113, the output 114 of which is c k,n . Similarly, the inputs are taken to AND gates 107-111, a 4  to each gate and the other inputs singly to respective gates. The output 116 of OR gate 115 is d k,n . A further circuit, Fig. 4, is adapted to provide a similar 2-bit output indicative that less than or equal to i of n binary inputs is equal to 1, in this event where n = 4, i = 3. As shown 3 OR gates 119- 123 receive a respective one of 3 of the inputs and the inverted 4th input. Their outputs are coupled to an AND gate 127 and the 2-bit word 13 composed of the 4th input non-inverted, and the output 126 of gate 127. The equations of this circuit for the general case are provided in the Specification. These two types of circuit may be combined, Fig. 8 (not shown) to provide a 2-bit word indicative of whether the number of l's in an input set is greater than or equal to k and less than or equal to i.

Patent GB-574074-A (GB)
Title: Improvements in or relating to mountings for vibratory bodies
IPC: B64D27/04
Filed: 1943-12-30
Abstract: 574,074. Resilient mountings. BRISTOL AEROPLANE CO., Ltd., and BERRY, P. E. Dec. 30, 1943, No. 21863. [Class 108 (iii)] [Also in Group XXXIII] A vibration-damping mounting for an aeroengine or other apparatus comprises two sets of elastic devices; torsiona and angular vibration are each separately controlled by the two devices, whilst linear vibra tion is controlled jointly by both. One of the devices functions in two directions with differing resilience, and th three modes of vibration can thus be decoupled, i.e. suitabl resonant frequencies can be in dividually selected for each mode. In Figs. 1 and 3, radial aero-engine 12 is mounted on a frame ring 11 by fou groups of links. Each group comprises an integral outer pair 18 pivotally connected at 19 to the engme, and a single inner link 22 connected with the engine by a universal joint 23. The frame ends of the links are fitted with rubber bushes 24a, 24b and are carried between brackets 14 on frame 11 by a hinge pin 16. Bushes 24a of the outer links 18 deflect axially as well as radially, and have snubbing discs 27 ; bush 24b of the centre link 22 deflects radially only. The directions of the outer links 18 converge at the centre of gravity Z of the engine, whilst the inner links converge at a point O on the engine axis in front of the centre of gravity. Torsional vibration is absorbed by axial deflection only of the rubber bushes 24a of the outer links 18, the universal joints 23 preventing torsional vibration reaching the inner links 22. The stiffness of bushes 24a under axial deflection is therefore given a value for a suitable resonant torsional frequency. Angular vibration occurs about the centre of gravity Z, and is not transmitted to links 18 since they converge at that point, but is received by the inner links 22 and absorbed by radial deflection of bushes 24b. The stiffness of these bushes under radial deflection is likewise given a value for a suitable resonant angular frequency. Linear vibration in a plane normal to the engine axis is transmitted to all the links and is absorbed by radial deflection of all the bushes as well as by axial deflection of the outer bushes 24a. A suitable resonant linear frequency is obtained by selecting a value for the one remaining stiffness : that of the outer bushes 24a under radial deflection. In the modification of Fig. 2 (not shown), the outer links 18 converge at a point on the engine axis behind the centre of gravity. The arrangement functions in substantially the same manner as that of Fig. 1. Equations relating to the three values of stiffness with other dimensions in order to obtain decoupling are given.
