Title: Electronic Multichannel Device for Sorting Coded Intelligence
Inventor: HAVEL JAN
IPC: G06F7/24
Filed: 1966-05-23
Abstract: 1,151,377. Random number generators. CESKOSLOVENSKA AKADEMIE VED. 23 May, 1966 [21 May, 1965], No. 22885/66. Heading G4D. Trains of randomly-occurring pulses are produced at output terminals 1-10 from an input train of evenly-spaced but randomly occurring " 1 " and " 0 " pulses on terminals 111, 112, the probability of pulses at the terminals 1-10 being different and the sum of the probabilities being 1. The arrangement is effectively reset after every ten " 1 "and " 0 " input pulses so that every ten consecutive input " 1's " and " 0's " may be regarded as a tenbit binary number N which is applied to logic comparison circuits 31-39. The other input to each comparison circuit is a repetitive, different sequence of " 1's " and " 0's " on terminals 211, 212-291, 292, each sequence being regarded as a further ten-bit binary number Vi. Circuits 31-39 each provide an output indicating whether N#Vi or N<Vi to set a corresponding bi-stable circuit 51-59 in one state or the other. An indication of the interval Vi to Vi + 1 in which the number N lies is obtained from logic circuits 602 in response to an interrogating pulse 14 and a gating pulse 15. If the range of 2<SP>10</SP> possible values of N is divided into unequal intervals by Vi, then the probability of N lying in an interval Vi to Vi + 1 is different for each interval and the probability of an output pulse at terminal 1-10 corresponds. The various probabilities are selected by choice of Vi. Transistor circuits for each functional unit of the arrangement are described.

Title: An extensible table
IPC: A47B1/02
Filed: 1937-08-21
Abstract: 490,629. Extensible tables. BARLOW, E. W. Aug. 21, 1937, No. 22973. [Class 52 (iii)] In extensible tables of the type comprising drawout end leaves 15, 15a normally overlying one or more centre leaves 14, the end leaves are provided on the underside with a cavity in which, when the table is contracted, the centre leaves are substantially wholly concealed, the contours of the longitudinal edges of the centre leaf, formed upon immovable parts of said leaf, matching those of the end leaves so that, when the table is extended, the upper surfaces of the marginal parts are flush with one another. The end leaves are interconnected for simultaneous operation by two pulley and cable systems 22, 24 and the centre leaf 14 is urged upwards by compression springs 27 in telescopic housings 26, 28 the upward movement being limited by fingers 29 engaging the undersides of the end leaves. To collapse the table one end leaf is pulled out slightly, releasing tongue and slot connections 30 between the abutting edges, and the centre leaf forced downwards against the action of the springs 27 until a pawl 31 engages a catch 32 to hold the leaf down. The end leaves are then moved inwards, ramps 35 on their runners 16a releasing the pawls 31 from the catches 32 at the end of the movement. The downwardly directed marginal parts 33 of the end leaves overlap and conceal the longitudinal edges of the centre leaf, which is slightly narrower than the end leaves. Baize pads 34 are attached to the interior of the marginal parts 33. To lock the end leaves in the extended and contracted positions a locking plunger 37 enters either of two holes in the runner 16a. The table may have a fixed centre leaf and one or more depressible centre leaves normally covered by the end leaves. Specifications 379.622, 434,777, and 461,925 are referred to.

Title: Frequency-sensitive circuits
IPC: H03H11/04
Filed: 1973-05-15
Abstract: 1411698 Active filter elements WESTERN ELECTRIC CO Inc 15 May 1973 [18 May 1972 24 July 1972 9 Aug 1972 22 Nov 1972] 22999/73 Heading H3U A frequency sensitive circuit element comprises a number of capacitors 10, 11, 12 interconnected between a set of more than two terminals 13, 14, 15 and means for sequentially connecting the terminals in different paired combinations between an input 18 and an output 19, each combination including at least two capacitors connected in series. In a three capacitor element the capacitors may be #-connected, as shown or Y-connected Fig. 1B (not shown). In Figs. 1A, 1B the connection between input and output is by means of a rotating switch having six positions in which the connections are 13, 14 (as shown) 13, 15; 14, 15; 14, 13; 15, 13; 15, 14. If the switch is rotated with a frequency f0 the element is equivalent to a parallel resonant circuit of capacitance 3C/2 and inductance 1/6#<2>f0<2>C. Instead of rotating switches the switching may be effected by electronic switching circuits Figs. 2, 3 (not shown). The element (CCU) may be used in an L-section network, either in the series arm to give a bandstop response Figs. 6A, 6B (not shown) or in the shunt arm to give a bandpass response Figs. 7A, 7B (not shown). The other arm in either case is a resistor. Sections may also be connected in cascade, Fig. 9 (not shown), the switching sequences of cascaded sections being phase displaced. An improved bandstop filter, Fig. 8, having a lower noise level, is obtained by connecting the filter input via the element CCU to one input of a differential operational amplifier 53 and also connecting it via a resistive L-section 57, 58 to the other input. A number of elements may be connected in parallel to a common amplifier, using phase displaced switching sequences Fig. 10 (not shown) and cascaded arrangements using amplifiers are also described Figs. 12, 13 (not shown).

Title: Fluid-Actuated Code Translator
IPC: G05B19/44
Filed: 1968-05-15
Abstract: 1,162,940. Interpreter. INTERNATIONAL BUSINESS MACHINES CORP. 15 May, 1968 [8 June, 1967], No. 23031/68. Heading G4M. A record card interpreter includes a plurality of combinations of pneumatic sensing means, each combination 16, 17, Fig. 1, being associated (a) with gating means 18, 19, so arranged that a high pressure output 32 is only produced when a particular character ("Y" as shown) is sensed, (b) with a bi-stable circuit 35, and (c) with a print hammer 37 controlled by a piston and cylinder 36, 48, and the arrangement is such that when the particular character is sensed, the resulting high pressure output 32 turns "on" the bi-stable circuit 35 causing pressure 66 to be applied to the piston 36 which moves the print hammer 37 and at the termination of its stroke issues a pulse 70 to reset the bi-stable circuit 35. The circuit employs diaphragm valves as described in U.K. Specification 1,055,045, which is referred to, each being drawn in its open position. Recognition of a particular character requires that certain holes be present and certain holes be not present (e.g. "Y" is 0, 8, but "," is 0, 3, 8 and "%" is 0, 4, 8, so that recognition of Y requires the presence of holes 0 and 8, but the absence of holes 3 and 4). Holes that should be present are arranged to block vents 29, 30, so that if all the holes that should be present are present, pressure builds-up in the tube 27, because of a restriction 28, arid holes which are present but which should not be present are arranged to close one or more valves 19 to isolate the lower end of tube 27 preventing a pressure build-up. In the bi-stable circuit 35, all valves except valves 46 and 60 are normally open, as shown, but valves 46 and 60 are normally closed. In this condition-the reset condition-pressure is applied to the top of a diaphragm unit 52 and 47 to the left-hand side of the piston 36, thereby maintaining the print hammer in its retracted position. A pressure 32 pulse from the lower end of tube 27 closes a valve 51, removing pressure from the top of diaphragm unit 52. The diaphragm 53 then flips over resulting in the opening of valve 46 and the removal of the reset pressure on the left-hand side of piston 36, and in the opening of valve 60 and the application of operating pressure 66 to the right-hand side of piston 36. At the end of its stroke, operating pressure is applied to a pipe 70, which momentarily closes a valve 58 and the circuit restores to its reset condition. In a modification (Fig. 3, not shown), the sensing arrangement and the bi-stable circuit have separate sources of pressurized air.

Filed: 1952-09-15
Abstract: 728,304. Semi-conductor rectifiers. GENERAL ELECTRIC CO. Sept. 15, 1952 [Sept. 15, 1951], No. 23109/52. Class 37. A rectifier element comprises two plate members providing a sealed cavity which encloses a semi-conductor element comprising a rectifying barrier, the element being secured to one plate member and connected to the other, and the plate members having a first insulating washer between their edge portions and a second insulating washer which overlies one edge portion and is engaged by the other. In Fig. 1, the metal plate members 1 and 2 are sealed together by a rubber washer 7 and a cambric washer 6. A semi-conductor element 8 comprising a P-N junction is conductively secured to plate 1 and a spring 15 connects the opposite surface of the semi-conductor to plate 2. Portions 11, 12 of impurity deposits, which may be utilized for the production of the P-N junction as described in Specification 727,900 may be provided between the semi-conductor and the connections. The plate members have a projection 14 and depression 16 respectively, which provide engagement means so that a pile of similar elements may be stacked together. The engagement means may be provided by other shapes, such as one having a snap fastener action. The depression 16 may also be shaped to contact the semi-conductor element directly instead of having spring 15. The metal portions in contact with the semi-conductor conduct heat to provide cooling during operation. Germanium may be used for the semi-conductor element, and fernico for plate 1, so that these elements have the same thermal expansion characteristics. Fig. 4 shows a mounting arrangement in which a number of rectifying elements 2, of the type described, are stacked between bars 24 of insulating material. The elements are connected in series between end plates 27 and 28, contact being ensured by resilient tab 32. In Fig. 6, the elements are mounted on a sheet 35 of insulating material, and held in position by resilient conducting strips 36 which connect the elements in series.

In Fig. 2, member 5 can be moved sideways or backwards and forwards, in each of which four positions a plunger 14a is moved outwards against spring pressure to bridge contacts 19, 21b, the contact 19 being common to all four switches. Two further switches may be selectively operated when the member 5 is in its central position by rotation of the member 5. The part 9 of member 5 is of rectangular section and bears in a slot in a disc 12 carrying contacts 27, 28, Fig. 5, which selectively bridge a common contact 29 and one of contacts 30a, 30b. In a modification, Fig. 8, the member 5 carries an oval plate 35 which on rotation closes either spring contacts 36a, 36b or 36c, 36d. Four further sets of contacts 37a-37d, at a higher level, are selectively closed by tilting the member 5 which is urged to its central position by a spring (not shown). In a further modification, Fig. 9, the plungers 14a actuate self-contained tumbler switches (not shown) and rotation of plate 12 actuates either of two further switches 42a. The member 5 may be guided in a cruciform slot and may have a knob bearing the replica of an aircraft.

Title: Improvements in the production of animal feeding stuffs and of additives therefor
Inventor: PRESTON WILLIAM
IPC: A23K1/00
Filed: 1955-08-11
Abstract: Animal feeds and feed supplements, suitable for bagging and for ready mixing with other feed ingredients, are made from masses of unstoned agglomerated dates, e.g., the palm-leaf packages thereof, by breaking up the masses and, at the same time, mixing in sufficient ground cereal, e.g., barley meal passing a 1/8 in. screen, to coat the date pieces, and then drying the mixture without decomposing it.  The drying may be effected in a tunnel drier at not above 300 DEG F. by hot air or furnace gas until the product is hard and friable.  The breaking up and mixing may be continued until the mixture is a paste, and the paste extruded into the drier, the stones being removed before or during the extrusion.  Stones may be removed after the drying.  The dried product may be ground; dried stones may be ground separately and mixed with the ground date product.  Dried products may be made into a stiff dough with water, the dough moulded to blocks or extruded to rods or threads, and the blocks, rods or threads again dried.  Tendency of the products to bind on absorbing moisture from the air may be offset by coating with kieselguhr or the like.
