The wall 210 and the dividing wall 45 are carried on a pivoted frame 214 held by a latch 216 in the loading position shown, which latch is released to allow spring 65 to move the walls into operative position. The separating means for the hopper 200 is the same as that for the hopper 41. The separating and feed rollers for the hoppers 41, 200 are rotated only when the motor 87 is rotating clockwise or counterclockwise respectively, and when a respective solenoid (106) or (366) is energized. For stacking, the motor rotates counterclockwise but neither solenoid is energized, while a diverter 204 directs a ledger to the main or auxiliary compartment 43, 202 under the control of a solenoid 205. A stacking ram 206 pivoted at 206d is moved clockwise by stacker roller 149 to compress the ledgers in the compartment 43 when the motor rotates clockwise, and is retracted during a stacking operation. For a parking or hold operation, the motor rotates counterclockwise a limited amount to hold a ledger with its leading edge on line X-X and its trailing edge on line Y-Y, in which position its trailing portion acts on a diverter 208 to swing the latter into a position wherein a ledger in the accounting machine is ejected along a path P3 for manual removal, and wherein a ledger can be manually fed into the machine along the path P3. The motor is later reversed to return the parked ledger to the machine.

Abstract: 1,002,193. Filters. DAVEY, PAXMAN & CO. Ltd. Dec 23, 1963 [Dec 24, 1962], No. 48546/62. Heading BID. [Also in Division F4] To release liquid in a filter cake 5 retained on a compartmented filter cloth in a rotary vacuum filter after liquid has been filtered through the cloth, a press platen with a flexible and impervious pad 3 is lowered on to the face of the cake 5 and forms a seal with the sides of a compartment 4, vacuum under the filter cloth then increases due to closation of air flow through the cake and the difference in pressure below and above the platen squeezes moisture from the cake. After the required pressing the vacuum is broken by pulling the corners of the pad away from the sides of the compartment. This is effected by a lost motion mechanism 8, 9 operated by a shaft 2 which causes cords 7 to shorten, so breaking the seal before the platen is lifted off. The filter cloth is carried on a frame 15 rotated by a motor 17 driving a variable speed unit 18 and gears 19 and 20. Vacuum is applied via pipe 21 and passage 22 to the underside of the compartments 4. The structure carrying the platens is independently rotatable but when lowered to engage the compartments rotates therewith. Such platens may also be used with horizontal band and tray type filters.

Title: Hot Chamber Die-Casting Machines.
Inventor: SMITH STANLEY
IPC: B22D17/04
Filed: 1966-10-31
Abstract: 1,185,467. Casting-machines. E.M.B. CO. Ltd. 30 Oct., 1967 [31 Oct., 1966], No. 48683/66. Heading B3F. [Also in Division F1] In a hot-chamber die-casting machine, for a slow movement of the injection plunger (not shown) to charge the gooseneck with molten metal before injection and a slow return movement after injection (for slow recharging of the injection cylinder), the injection plunger is connected by a stem 2 to an operating piston 1, air-driven in a cylinder 4 and slidable on a fixed tubular spigot 8. Air from a supply pipe (not visible) passes through a permanently open connection 14 to a space 6 (around the piston 1 and below a flange 3) to bias the piston constantly upwards, while air can be passed from the supply pipe through a valve 12 to a passage 11 through an end plate 7 of the cylinder 4 to the interior of the piston. With these air connections, the areas of air pressure on the piston 1 are such that there is a net upward force on it, but a restricted flow of air past a non-return and restricting ball-valve 20 to a top margin of the piston causes a slow descent of the piston and attached injection plunger to charge the gooseneck slowly. There is rapid injection of the metal into the die cavity when ports 9 in the spigot 8 are uncovered by the piston descent, but when the valve 12 is then operated to exhaust the air above the piston through a pipe 13, the pressure in the space 6 causes the piston and plunger to rise. This rising return movement is slowed when the ports 9 are again covered by the piston, the speed being then determined by the air flow to the passage 11 past another non- return and restricting ball-valve 17, so that the injection cylinder (not shown) is slowly recharged. Movement of the ball valves 17, 20 is limited by adjustable stops 19, 22.

An ohmic contact is made to a silicon body by treating its surface to remove any oxides and/or silicates, then heating in nickel carbonyl to deposit a thin layer of nickel, which acts as a wetting agent in the subsequent soldering of the body to a metal contact. In a typical case the silicon body initially of N or P type, is provided with a PN junction and low resistivity surfaces by diffusion into opposed surfaces from boron trioxide and phosphorous pentoxide. The diffusion is carried out at 1300‹ C. in oxygen, and the resulting glassy residues removed by soaking in hydrofluoric acid, rinsing, and then sandblasting or etching in hot aqueous alkali hydroxide or a specified mixture of nitric, acetic and hydrofluoric acids. Several of the bodies 10 are then nickel plated first on one face and then on the other, in the apparatus shown in Fig. 3 as they are conveyed from the heated end 17 to meet a flow of helium, argon, or carbon dioxide and nickel carbonyl. The deposited nickel may include traces of carbon which assist in the wetting process. After subdivision by scribing and breaking, ultrasonic cutting, or etching through a mask, the plated bodies are assembled with discs of solder between molybdenum or copper plates with a further solder disc between one plate and a lead wire, and heated to 430-490‹ C. in inert or reducing gas to form an integral assembly. Typical solders are alloys of lead and tin in the weight proportions 60: 40 and 95: 5.

Abstract: 1359693 Frequency detectors INTERNATIONAL BUSINESS MACHINES CORP 27 Oct 1971 [18 Dec 1970] 49816/71 Heading G4H [Also in Division H4] A detector for detecting which of a plurality of predetermined frequencies exists in an input signal includes a comparator for comparing the input signal with test signals at the predetermined frequencies to determine the best match. As described for input tone signals at terminal 1, Fig. 2A, comprising two frequencies each selected from one of four frequencies A1-A4, B1-B4, the A component is derived by feeding the input signals via low pass filters 17 and saturating amplifier 19, which clips it, to sixteen AND gates 221-236, Fig. 2B. From oscillators 100, 101, 102, 103 feeding signals 4A1, 4A2, 4A3, 4A4, to squarers 190-193 and dividers 120-123; 140-143, four square wave signals, phase displaced from each other by 90 degrees, are derived for each signal frequency and fed as a second input to one of the AND gates 221-236. Each gate is connected via a filter 25 to one of four analogue OR gates 28-31, each associated with one of the frequencies A1-A4. The frequency present in the input signal is detected by determining which gate has the largest output signal in a maximum selection circuit 54, Fig. 2C, comprising transistors 37, 41, 146, 50. A bias voltage for a buffer transistor 45 (receiving at its base the filtered output from AND gate 46 receiving at its inputs the squared output of a high frequency oscillator 47 and saturating amplifier 19) is applied to the emitters of the transistors 37, 41, 146, 50 to the bases of which are applied the outputs of the OR gates. When one of the transistors is rendered conductive, an associated transistor 38, 42, 47, 51 also conducts to deliver an output of one of four leads. The input tone signal is similarly applied via a high pass filter 18 to similar circuitry (Figs. 2D-2S, not shown) to detect the B component of the input.
