Title: Improvements in or relating to laminated springs and their manufacture
Inventor: FIELDING RONALD
IPC: B21D53/88
Filed: 1961-10-03
Abstract: 949,337. Making springs. ENGLISH STEEL CORPORATION Ltd. Sept. 18, 1962 [Oct. 3, 19611, No. 35682/61. Heading B3A. In a method of pre-stressing individually the leaves for a laminated spring, each leaf after hardening and tempering is pressed or rolled to impart a specified deflection to stress it past its yield point. A plate 1 is subjected to a bending moment Mb sufficient to cause plastic deformation of the fibres in the vicinity of the faces 2 and 3. Within an inner zone 6 there is elastic deformation only and the stress rises to a value f a , in the outer zone 8A on what will be the tension side there has been plastic deformation and the stress rises to a value f b . When the moment M b  is removed there are residual stresses distributed as shown in Fig. 5, there being a residual compressive stress f r  in the outer fibres, which changes to a tensile stress near the surface, and drops to zero at the neutral axis. There is a similar residual tensile stress at the compression face of the spring. Under working conditions the stress in the fibres near the surface of the plate is reduced by the amount of the residual stress, and the material nearer the neutral axis plays a greater part in taking up the total stress because of the additive effect of the residual stresses. The prestressing is effected by pressing between form tools, or by passing between rolls which reverse the curvature. An example gives details of the stress and strain produced.

Title: Improvements in or relating to locking devices for turntable structures
IPC: E02F3/352
Filed: 1968-07-26
Abstract: 1,211,939. Shovelling machines; remotely controlled fastenings. ENVIROTECH CORP. 26 July, 1968 [1 Sept., 1967], ,No. 35722/68. Headings E1F and E2A. A locking device for permitting of the locking together of the relatively movable decks of a turntable when the decks have one particular relationship with one another comprises two spaced apart pawls 21, a stud 40, and an actuator S. The pawls are slidably mounted in a housing C to extend, when the housing is secured to one deck, through a hole in the deck for engagement with the stud, which is mounted on the other deck, preferably in a resilient bush housed in a recess in the deck. The actuator S is a piston cylinder unit having a fixed piston P and a cylinder 30 freely floating about the piston. The construction of the pawls and the relationship between the pawls and the actuator is such as to provide for a lost motion connection therebetween so that when the chamfer 24 on one or other of the pawls is engaged by the stud, as the desks approach said particular relationship with each other, the pawl rules over the stud. The pawl then becomes locked between the studs until the pawls are moved clear of the stud by movement of the cylinder 30 on pressurised fluid being admitted into the cylinder. The turntable can be incorporated in an overthrow type shovelling machine.

Abstract: 1521479 Semi-conductor bi-stable PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Aug 1975 [2 Sept 1974] 35731/75 Heading H3T A bi-stable circuit has two sets of transistors 33, 34 and 35, 36 with the emitters and collectors in each set respectively connected together, one transistor 34, 35 in each set is cross coupled to form the bi-stable, with load resistors 39, 40 and a common emitter resistor 38, a base of a transistor in each set not involved in the cross-coupling is connected to an output of a combinatory logic circuit which has built-in redundancy, this can be tested because co-existent signals on these outputs 24, 25 can make both sets of transistors conduct at the same time with the result that if the load resistors 39, 40 have a resistance small with respect to the common emitter resistor 38 they carry substantially equal currents so that an output signal of the bi-stable circuit has a state intermediate between the two states of the bi-stable. The outputs of the bi-stable at the respective collectors can be connected to the bases of transistors 44, 45 forming a long tail pair, an output being taken from a collector of the pair. Further transistors 32, 37 can be connected with inputs C, D applied to their bases which are additional to the inputs A, B of the combinational logic circuit. The symbols 13 used for the combinational logic denote AND gates with a negated (NAND) output available at the output 24 marked with a lateral slash.

Title: Improvements in or relating to electric circuits incorporating grid-controlled gas-filled electric discharge devices
Inventor: COOK KENNETH GEORGE
IPC: H01J17/44
Filed: 1968-07-30
Abstract: 1,212,100. Gas-filled thermionic valves. M-O VALVE CO. Ltd. 1 July, 1969 [30 July, 1968], No. 36415/68. Heading H1D. In the firing of a gas- or vapour-filled electric discharge device, e.g. a hydrogen thyratron, having an anode at a positive potential, a cathode and two further apertured electrodes disposed between the anode and cathode, a positive triggering pulse exceeding the ionization potential of the gas filling is applied between the cathode and the further electrode nearer the cathode to initiate a discharge between the anode and cathode and the other further electrode is maintained at a negative potential with respect to the cathode at least for the period during the application of the triggering voltage. This arrangement facilitates a rapid rise in the anode-to-cathode current to a maximum value since the presence of the negatively biased further electrode allows the density of the plasma produced by the application of the triggering pulse to reach a high value before conduction to the anode starts. The two further electrodes may be generally planar, metal members having aligned apertures of the same size and shape. The said other further electrode may be maintained at a constant potential negative with respect to the cathode throughout operation of the device.

Abstract: 1,131,748. Glass filaments. OWENS-CORNING FIBERGLAS CORP. 15 Aug., 1966, No. 36445/66. Heading C1M. [Also in Division D1] Streams of glass fibres 20, Fig. 1, issuing from orifices are gathered into a strand 22 whilst they are being attenuated by means of a driven wheel 30, the strand 22 contacting not more than 90 degrees of the peripheral surface of the wheel 30. The wheel 30 delivers the strand at a constant rate to the winding means 20 that winds the strand at a predetermined tension substantially less than the tension imposed on the strand by the attenuating wheel 30. The glass fibres 20 initially pass over a felt pad 25 impregnated with coating, lubricating or sizing liquid. The fibres 20 are then gathered into a strand 22 and passed over a traversing mechanism 27 before being attenuated by the driven wheel 30. The winding means may be driven by an electric motor having a small but constant torque sufficient to provide the necessary tension to take up the strand supplied by the wheel 30. Additional liquid may be supplied by a nozzle 31.

Title: Method and apparatus for automatic fault diagnosis of electrical  circuits employing on-line simulation of faults in such circuits  during diagnosis
IPC: G06F11/22
Filed: 1974-08-20
Abstract: 1428944 Testing logic circuits GENERAL RADIO CO 20 Aug 1974 [19 Feb 1974] 36558/74 Heading G1U A method of testing a logic circuit comprises the steps of:- (a) applying a sequence of test words to the circuit under test and comparing its outputs with the expected outputs, (b) upon detection of a disagreement between the actual output and the expected output stopping the sequence of test words and extracting from a partial fault dictionary a list of potential faults any one of which could have resulted in the observed disagreement, (c) for each potential fault, simulating a circuit of the type under test that includes the fault, and comparing its output in response to further words of the test sequence with those produced by the circuit under test in response to further words of the test sequence. Thus, the inventive method is a combination of the two known methods, namely (1) using a complete fault dictionary - which requires an enormous store - and (2) simulating for each circuit under test all possible faults - which is time consuming - and according to the Specification by a judicious mixture of these two methods significant savings in time and equipment can be achieved whilst still identifying about 90% of the faults in circuits found to be faulty.  The Specification includes high level block diagrams showing how the method may be implemented, and a general discussion of the problems of testing large scale integrated logic circuits.

Abstract: 918,109. Pneumatic article-conveying apparatus. AMERICAN MACHINE & FOUNDRY CO. Oct. 27, 1960 [Oct. 30, 1959], No. 36983/60. Class 78 (1). Cigarette packages P are fed by a reciprocating plunger 18 to a station I. They are then drawn by suction along a tube 10 to a shoot C. Suction is provided by a compressor (not shown) connected to a tube 20. The shoot C comprises endless belts 36, 38 which feed the packages P to an outlet tube section 63 leading to a station II. Packages already in the section 63 are prevented from being subject to the vacuum by the action of a gravity-biased gate 94 pivotally mounted at 96. Should the packages P in the outlet section tube 63 accumulate a switch 111 is deflected, thereby energizing a solenoid 116 so as to project an arm 120 to block the entry to the tube 10. Since a minimum number of packages is necessary in the tube 63 to feed to a cartoning machine, a switch 126 is connected to the control system of the cartoning machine or a conveyer D leading thereto and is actuated when the height of the packages P falls below a predetermined amount in the tube 63. The belts 36 and 38 bear on respective plates 54 and 56 which are slotted at 58 to permit the vacuum to be transmitted from the tube 20 through holes 40 in the belts to the tube 10. The spacing of the plates 54, 56, is adjusted by means of screws 76, 76 so as to accommodate packages P of different thicknesses. The tension of the belts 36, 38 may be adjusted by means of screws 88, 88. A guide plate 102 in the shoot C is adjustable by a screw 104. The degree of vacuum may be adjusted by sliding a panel 100 formed with slots 106 relative to screws 108 so as to suitably adjust the uncovered portion of an opening 29. The front 30 of the casing of the shoot C may be of transparent material. The reduction of negative pressure in the tube 63 may be further reduced by forming this with perforations.
