Abstract: 492,106. School-desks. KINGFISHER, Ltd., and CHATWIN, A. March 15, 1937, No. 7469. [Class 52 (iii)] In school-desks provided with lockers, the lid j is mounted at its rear edge on hinges provided on carrier members e adapted to slide on bars c fixed to the desk sides d so that the lid may slide either when raised or lowered, the carriers providing the means whereby the lid may be supported in an inclined position, in which the underside serves as a support or easel, and also providing means whereby it is maintained in any position along the bars. The bars c are spaced away from the side walls d of the desk by distance pieces at each end and the semicircular carrier plates e have side flanges with holes through which the bars c pass. Angle strips i pivoted to the plates e are fixed to the side edges of the lid j and have tail pieces abutting against the front flange f of the carrier plates when the lid is raised. A further stop projection n may be provided. In the raised position, the weight of the lid causes the carrier plates to be clamped on the bars c.

Fig. 10 shows a modification in which the semicircular carrier plate s has its curved edge directed downwardly and flanged inwardly at t, the bar v passing through holes in this flange. At the front edge of the flange is a lug w adapted to contact with the tail piece of the angle strip i to form a final stop, and holes y in the tail piece may be engaged by a spring-pressed peg z on the carrier plate to give several inclined positions for the lid.

Title: Electronic data processing apparatus
IPC: G06F9/28
Filed: 1961-03-06
Abstract: 966,189. Digital electric calculators. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 6, 1961 [June 6, 1960], No. 8002/61. Heading G4A. A distinction is made between the performance of non-arithmetic and arithmetic instructions which latter require the use of the arithmetic unit of a computor. The two kinds of instruction are performed under the control of separate sets of command generators, 50 and 52 for non-arithmetic instructions and 42 to 48 for arithmetic instructions. An instruction is decoded to set a single core in a decoder (Fig. 2). The core is then reset to set a row of the first level command generator 50 or 42 by a signal on winding 112 (Fig. 8). A timing signal generator then issues pulses TP0 to TP9 which successively reset the cores of the row. Each core has permanent windings 122, 126 which can be patched to command wires. Thus in the first row the third core will generate command A, the fifth and sixth cores command B and the third core command C. One of the cores of a row is used to set a row of a second level command generator 52 or 44 and this issues command signals simultaneously with the first level generator 42 or 50 set as a result of the next instruction. The system is designed to operate on alternate arithmetic and non-arithmetic instructions and flip-flops 64, 66 supply voltages to the decoder to ensure that the selected core is reset only if the instruction is of the appropriate kind. Under the most favourable conditions it is possible that command generators 42, 52 and 46 or 50, 44 and 48 will generate signals relating to the performance of three successive instructions.

Title: Improvements in or relating to the tyres of tramway and railway wheels
IPC: B60B17/00
Filed: 1921-03-14
Abstract: 181,481. Vickers, Ltd., and Sumpter, C. L. March 14, 1921. Hardening.-Relates to the hardening of the tyres of tramway and railway wheels and consists in hardening the sides of the flanges of such tyres by the process set forth in Specification 5588/10. The treatment may be applied in the manufacture of the tyre or it may be applied to a tyre in the working position when re-hardening is rendered necessary by wear. In carrying out the process, the wheels or a pair of wheels on their axle are slowly rotated whilst a blow-pipe flame is applied with a wavy motion to the side of the flange requiring treatment, cooling being effected by rotating the wheel through water or by applying a jet of water immediately behind the flame. When both sides of a flange are to be treated, a jet of water is provided on each side so as to prevent the drawing of the temper of the first-hardened side during treatment of the reverse side.
