Patent GB-1172845-A (GB)
Title: Improvements in or relating to Calculating Machines
Inventor: DRAGE JAMES JOHN
IPC: G06F7/498
Filed: 1966-01-03
Abstract: 1,172,845. Electronic keyboard calculators; multiplication. BELL PUNCH CO. Ltd. 3 Jan., 1967 [3 Jan., 1966; 31 March, 1966], Nos 386/67 and 387/67. Divided out of 1,172,842 and 1,172,843. Addition to 1,042,785. Heading G4A. A calculating machine having a keyboard with a single order of digit keys and at least two registers each comprising a plurality of electric pulse-operated counting devices into which numbers entered from the keyboard may perform multiplication calculations involving numbers in two of said registers, the product being developed in one of said two registers. As described, numbers are entered from a keyboard 11 into a visual register 20 associated with number display tubes (Fig. 1, not shown) and may be transferred from there into one or other of two store registers 22, 23, the register comprising decade pulse counters. For multiplication, the multiplicand is in store register 22 or 23 and the multiplier in visual register 20. The tens complement of the digit in stage R3 of the visual register 20 is first fed into a buffer counter 35 and stages R1-R3 cleared. Pulses corresponding to the digits in stages r12 and r11 of the store register are then fed into stages R2 and R1 of the visual register a number of times equal to the original digit in R3 (as determined by buffer counter 35 which is stepped on each time until it reaches zero state); any overflow being stored in the stage R3. The complement of the contents of stage R4 is then fed into buffer counter 35 and pulses corresponding to stages r12-r10 are fed into stages R3-R1 with R4 storing any overflow. This process is repeated for all of the stages R3-R12. Gates and timing circuits for controlling these operations are shown and are described in the Specification. Control of the stages to which the various pulses are fed at each phase of the multiplication is achieved by the slipping of one timing circuit 18 with respect to another 15, each timing circuit comprising a multi-cathode counting circuit (Fig. 2, not shown).

Title: Improvements in or relating to wooden doors, shutters and the like
IPC: E06B3/70
Filed: 1935-01-07
Abstract: 441,800. Doors and shutters. CHAPMAN, LOWRY, & PUTTICK, Ltd., Station Road, and CHEESEMAN, H. A. A., 17, Derby. Road, both in Haslemere, Surrey. Jan. 7, 1935, No. 481. [Class 20 (iii)] A door, shutter, or the like comprises a rectangular frame, the members of which are spanned by a series of horizontal, vertical, and inclined slats. In the construction shown, each frame member is made in two parts A, B, secured together by a tongue-and-groove joint, the inner part A being stepped to provide bearing surfaces for the ends of the slats. The outer bearing surfaces A<1>, A<3> form seatings for two sets of vertical slats D, E, which are nailed thereto ; the horizontal slats F are similarly secured to the stepped surface A<2>. The ends of the inclined slats G are nailed to the slats E or F, between which they are mounted. The end slats of the vertical and horizontal rows are nailed throughout their entire length to the corresponding stepped surface on the frame. The frame part B is slightly thicker than the frame part A and thus provides two further bearing surfaces for two panels C. The gaps between the slats may be filled in at H to form a solid portion for the mounting of a mortice lock, or, alternatively, the seating for the lock is provided by a block of wood which is secured to the frame and is suitably stepped for receiving the ends of some of the slats. A window frame, of hexagonal form for instance, may be let into the door, the outer circumferential face thereof being stepped to receive the ends of the slats which meet it.

Abstract: 668,109. Rail bonds. AVERSTEN, K. J. Jan. 9, 1950 [Jan. 10, 1949], No. 516/50. Class 38 (i). [Also in Group XXII] A method of electrically bonding a pair of rails by means of a pair of contact shoes connected by a conductor comprises inserting a contact shoe into a holder connected with a source of electrical energy, pressing the shoe against one of the rails and welding it thereto, the conductor being joined to the contact shoe prior to or subsequent to the welding operation. Each contact shoe 1 has a notch 2 in which a copper tube 3 soldered to the end of the conductor wire 4, is attached by soldering. The outermost ends of the tubes 3 have grooves 5 which grip and prevent movement of the strands of the conductor wire 4 which may be made of copper, steel or aluminium. One end of the shoe 1 may have a recess 6 covered by a conical lid 7 attached by an annular rim 8 on the shoe, the chamber so formed being filled with flux, or the end may have a solid conical tip. The tubes 3 may be dispensed with and the wires soldered directly to the shoes 1 in bores extending transversely or in part longitudinally through the shoe.

Title: Method of and apparatus for die casting under vacuum
IPC: B22D17/14
Filed: 1955-01-07
Abstract: 780,126. Casting - machines. MORGENSTERN, D. M. Jan. 7, 1955, No. 517/55. Class 83 (1). In a method of die-casting, the dies are moved into closely-spaced relation to each other or enclosed in an airtight enclosure which is then evacuated, the dies are closed while the enclosure is in evacuated condition, and the molten metal delivered to the die-cavity, chilled, the enclosure opened, and the dies opened for removal of the casting. The die-plates 1, 2 carry enclosure-members 6, 7, which together form a hood 5, the member 6 carrying a flexible sealing- gasket 10. The die-members 24, 25 define a mould-cavity 26, runner 27 and spine 28, into which molten material is injected from a container 52 by a fluid-pressure-actuated plunger 58. Flow of molten material to the container from the crucible 50 is through a port 53 controlled by a valve 65 on an arm 66 connected to a fluid-pressure-actuated piston 69. Coolant passages 103 in the die-member 25 are fed from a manifold 105, Fig. 6, having ports controlled by valves 113 which are connected, as appropriate, to the coolant passages through tubing 116, thus permitting the interchange of diemembers having different arrangements of cooling passages. Ejector mechanism comprises pins 36 on a head 35 carried by plungers 40 passing through lubricating-oil seals 43 in the dieplate 2, and engaging a stop 41 when the die is opened. In operation, closing the main switch 137, Fig. 10, places a vacuum tank 85 and suction pump 96 in communication through a valve 98, to establish a high vacuum in the tank. A start button 146 is then actuated to initiate the automatic cycle of actions. The die member 25 is moved towards die member 24 and stopped with the die members slightly apart, Figs. 1 and 10. The sections of the hood 5 are brought into a similar relationship, and the gasket 10 seals the joint between them. Valve 65 closes to shut off the charging cylinder 52 from the crucible 50, and the valve 99 is opened to subject the interior of the hood 5 and the die to the highvacuum in the tank 85. Thereafter the valve 98 is closed by the operation of a timer 182, and the hood subjected to the action of the pump only. The die and hood members are closed and the plunger 58 is actuated to force molten material into the die cavity. The cooling period is controlled by a timer 198, and just prior to the termination of this period, valve 99 closes, the valve 98 re-opens to connect the tank 85 to the suction pump, and valve 90 opens to connect the hood to atmosphere. The operation of the timer 198 opens the die and hood, the ejection of the casting being thereby achieved.

When pulses simultaneously occur on all the rectifier-containing leads B2, W the pulse on the resistance-containing lead B1, if it then occurs, is effective at the point PC. In all other circumstances at least one of the rectifiers is conductive and the voltage drop in the resistance Rh reduces the potential at the point PC below the pulse potential. Tube Va will not fire to less than the pulse potential. Specifications 636,700 and 701,739 are referred to.
