Title: Over current protection circuits
IPC: H03K17/08
Filed: 1975-08-26
Abstract: 1513920 Protecting transistor driver circuits INTERNATIONAL BUSINESS MACHINES CORP 26 Aug 1975 [18 Sept 1974] 35148/75 Heading H2K A driver circuit supplying current to a load CLOAD and having a pair of complementary transistors Q 7 , Q 8  in its output stage is provided with an overcurrent protection arrangement which produces a signal when the output current of one of the transistors is too high and disables the driver circuit if the integral of this signal reaches a threshold level. The driver circuit may be one of a plurality of similar driver circuits, connected to the same load, in which only one driver circuit should be enabled at any time. Should two of the driver circuits inadvertently be enabled simultaneously the respective protection arrangements in both of them will respond to the resulting overcurrent. The protection arrangement for a given driver circuit includes a separate current detector/integrator for each output transistor Q 7 , Q 8  responding either to the drain potential of the transistor or to the potential across a resistor in series with the transistor. If the integrator capacitor C 1 , C 2  in either detector/integrator attains its predetermined threshold voltage a latch circuit T 7 -T 14  changes state to provide a LOW signal to transistors X 4 , X 6 . This over-rides the ENABLE signal and disables the driver. The latch is reset when the ENABLE signal is removed. An indication that the latch has operated is given via T 15 .

Title: Method and apparatus for making bends in tubes
IPC: B21D9/08
Filed: 1958-11-03
Abstract: 898,795. Making waveguides; angular bending. WESTERN ELECTRIC CO. Inc. Nov. 3, 1958 [Nov. 12, 1957], No. 35158/58. Classes 83 (2) and 83 (4). Apparatus for bending a tube or waveguide comprises a base having a forming die pivotally mounted thereon, a wiper die secured to the base and having one extremity thereof adjacent to one extremity of the forming die, means for guiding a portion of the tube adjacent the wiper die, means for supporting the interior of tube during bending, means for pivoting the forming die, and means for clamping the tube pivotally with the forming die and slidably with respect thereto along the longitudinal axis of the tune. Waveguide tubing 30 is placed around one section 124 of a mandrel 130 with one wall of the tube in engagement with a wiper die 86 and a former die 56, then axially aligned. The mandrel section 124 is formed at one end with interconnected links 131 and at the other end is connected by a pin 115 with a link 111 in turn pivoted to a booster block 117. One end of the waveguide 30 is engaged by this booster block 117 and the other end is clamped adjacent the former die by a serrated clamp 171. A pressure die 277 is then moved in to prevent lateral movement of the waveguide 30 away from the wiper die 86. Another section 127 of the mandrel is then inserted into the waveguide so as to lie alongside the section 124, the section 127 being provided with interconnected links 132. The clamp 171 is slidable against a spring 204 on a bending head 34 which carries the former die 56. The head 34 is pivoted and swung to bend the waveguide 30 about the abutting comers of the wiper die 86 and former die 56 to form a sharp angle bend. The booster block 117 and clamp 171 are interconnected by arms 162 pivoted together at 168 spaced from the axis of rotation of the bending head 34, so that during bending the block 117 and the clamp 171 are caused to move longitudinally of the tube towards each other. The displaced material in the wall of the waveguide 30 flows outwardly into conical shape indentations 42, Fig. 5, and 72 formed in the flanged ends of pins 41 and 73 coaxial with the axis of the bending head 34, and in an indentation formed between curved surfaces 58 and 89 on the forming die 56 and the wiper die 86 respectively, as described in Specification 765,173 to which reference is made. The waveguide is slightly overbent to allow for spring back. After bending, an outer section of the bent waveguide may be removed and a flange secured thereto as shown in Fig. 19. To form a second bend in a previously bent section of the waveguide 30 the previously bent section is clamped in a clamp formed with suitably shaped corrugated jaws 213, Fig. 22, and 219 (not shown), and used in conjunction with the remainder of the bending apparatus described previously. Specification 771,087 also is referred to.

Title: Improvements in and relating to fifth wheel couplings
Inventor: SLAVEN JOHN GREENWOOD
IPC: B62D53/12
Filed: 1960-10-14
Abstract: 983,568. Fifth-wheel couplings. YORK TRAILER CO. Ltd. March 2, 1961 [Oct. 14, 19601, No. 35390/60. Heading B7T. As a trailer king-pin enters the slot 10 of a fifth wheel coupling it presses back slightly from the Fig. 2 position a wedge member 14 carried by a spring-urged lever 16 pivoted about its rearward end as shown in Fig. 1 and releases a pivoted hook 12 from a lock set position shown in Fig. 2 where it is jammed by the wedge. In the coupled up position, Fig. 1, a latch 20 pivoted at 24 is urged in an anti-clockwise direction by a spring 22 to block the path of travel of the lever 16. When the lever 16 is to be moved manually against its spring 18 to the unlocked position shown in Fig. 2 the latch 20 must first be manually pivoted clockwise by lifting a pin 26 to allow the lever 16 to pass over the top of the latch and bear hard against the other end of the latch to hold the coupling in the unlocked position. The wedge 14 is thereby removed from the locking position whereby movement of the king-pin out of the slot to uncouple swings the hook 12 and pushes back the slightly intruding wedge 14 and the lever 16. This action releases the latch 20 which pivots back to its Fig. 1 position and allows the lever 16 to move the wedge 14 to a lock-set position abutting the end 27 of the hook. The king-pin during coupling up pushes on the wedge tip of the member 14 and moves the lever 16 which releases the latch 20 so that it returns to the Fig. 1 position, and further movement of the king-pin into the slot swings the hook 12 into a position where it embraces the pin. The lever 16 under its spring action may now ride over the top of the latch 20 and insert the wedge between the hook and stops 30, 34. To take up wear on the parts the hook is provided with a slot 36 and the stop 34 is adjustable.

According to one construction, in which two girders of H section meet at right-angles, two clamping devices of similar construction are employed. Each clamping device comprises two metal plates C, Figs 1, 2, and 3, each carrying two jaws D which embrace and grip the flanges A<1>, B<1>, of the girders A, B respectively. The plates C are drilled to receive bolts E by means of which the brackets of each device are rigidly secured together. Packing pieces F, preferably wedgeshaped, may be employed between the jaws D and the flanges to ensure a firm grip. For girders of channel or angle section the clamping device comprises one such bracket used in conjunction with a flat plate engaging with the back surfaces of the girders.
