Title: Improvements in and relating to selection arrangements for electrical pulse systems
IPC: H04N5/213
Filed: 1946-03-14
Abstract: 620,585. Radio-receiving circuits; pulse amplifying circuits. PHILCO PRODUCTS, Inc. March 14, 1946, No. 7981. Convention date, March 14, 1945. [Classes 40 (v) and 40 (vi)] [Also in Group XL (b)] In a television receiver the separated synchronizing pulses are applied to a circuit resonant at the pulse frequency, by means of which the synchronizing pulse separator valve is gated in synchronism in order to prevent interference by transient electrical disturbances. Negatively modulated signals are applied to the grid 13 of the separator valve 10, which is self-biassed by means of a resistance 18 and condenser 17. Synchronizing pulses are taken off from the anode circuit, comprising the resistance 19 and an L.C. circuit 20, 22 resonant at the synchronizing frequency. The inductance 20 is centre-tapped, the sinusoidal wave appearing at the terminal 24 being applied over a condenser 25 and resistance 26 to an inner grid 16 of the valve 10 so as to render it non-conductive for the duration of the interval between successive synchronizing impulses. In an alternative arrangement (Fig. 3, not shown), the gating wave is applied instead to the grid of a separate valve connected in series with the cathode lead of the valve 10.

Title: Improvements in malting and apparatus therefor
IPC: C12C1/15
Filed: 1961-03-06
Abstract: In malting by the procedure in which the grain during germination is deposited in a row of batches of degrees of germination increasing successively from the charging end to the discharging end and the batches are moved along the row successively to the discharge end, a part of a particular batch next to the adjacent batch nearer the charging end is temporarily collected while movement of the succeeding batch is begun and the collected portion is then deposited in the ditch between the other part of the first batch and the transported part of the succeeding batch, the amount of the collected part being substantially the volume of the ditch.

Filed: 1947-03-25
Abstract: 624,392. Dust mop. JAYE, H. V., and SIGSWORTH, F. B. March 25, 1947, No. 8144. [Class 19] A dust mop 5 is attached to the lower end of an uncovered screwed shaft 12 of coarse pitch, the upper end of the screwed shaft being provided with a smooth extension 13 having an annular groove 14 for receiving two semi-circulai half-sections of a split thrust collar 15 which is rigidly secured to the lower end of a tubular element 16 forming an extension of a cylindrical tubular handle coupling 17  for the mop handle 20. Mounted upon the screwthreaded shaft 12 is an elongated internally screw-threaded nut 19 adapted for being held against rotation and to be moved longitudinally of the shaft 12 for causing the latter to rotate. When it is desired to free the mop from dust after use, the handle 20 is grasped by one hand and the nut 19 is held against rotation by the other hand and simultaneously reciprocated over the shaft 12, thus causing the shaft to rotate and the mop to whirl so as to free it from dust. The mop is preferably pivotally mounted on the screwed shaft, (as shown), by means of interfitting elements screwed on the mop element and shaft respectively and held together by a tightening nut.

Title: Improvements in and relating to methods of grid control of gridcontrolled vapour or gas discharge devices operating as inverters
IPC: H02M7/51
Filed: 1934-03-15
Abstract: 412,528. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. March 15, 1934, No. 8198. Convention date, March 15, 1933. [Class 38 (ii).] In a parallel-type inverter comprising gridcontrolled gaseous discharge devices 2, 3 associated with an output transformer 4 and commutating condenser 6, the grid potentials are derived from the D.C. side 1 of the inverter through an oscillation generator comprising a glow discharge tube 13, a condenser 11, and a grid-controlled auxiliary discharge device 15. The condenser 11 is charged through a resistance 12 to the breakdown voltage of the tube 13, whereupon flow of current through a resistance 14 causes the grid of the device 15 to assume such a potential that the latter becomes conductive, whereupon the condenser 11 discharges, and the sequence is repeated. The periodic variations in potential across the device 15 are applied through a condenser 17 to the grid transformer 8 whereby steep fronted potential waves are applied to the grid of the valve 3. In order that waves of similar characteristic may be applied to the grid of the valve 2, a voltage derived from the choking coil 7 on the input side of the inverter is superimposed on the voltage of the grid transformer.

Title: Automatic plotter
IPC: G06F3/13
Filed: 1973-02-20
Abstract: 1429522 Automatic plotter COMPAGNIE HONEYWELL BULL 20 Feb 1973 [25 Feb 1972] 8334/73 Heading G4H An automatic plotter provides a stepwise approximation (a) to the boundary (b) of the operating zone A of a system dependent on parameters (X, Y). In the embodiment of Fig. 2 the parameters undergo increments Px, Py in an area bounded by the lines X = Xm, Y = Ym and D1 which is divided into zones A, B by (b). Scanning is performed by means of "vectors" #, ## parallel to D1 and directed into and out of the operating zone, using the control circuit of Fig. 5. Starting from B (near D1), X, Y are incremented and decremented respectively by Px, Py (vector #) until a point in A is reached: this point is transmitted to the plotter and Y is decremented by Py. Vector ## is then scanned until a point in B is reached: the last point in A on is is transmitted to the plotter and Y is again decremented by Py. This procedure is repeated until Y reaches its minimum value Ym, whereafter #, ## are scanned as before but the zone B decrement Py becomes an increment Px, the final result being plotted as graph (a). In the circuit of Fig. 5 [with Px=Py=1], 30 (flip-flop) and 7 indicate the zone of the first and last point on the vector currently being scanned, 31 defines the vector (# or ##) to increment and decrement X, Y counters 33, 34 as appropriate, 10 compares the contents of 30 and 7 to determine when (b) is crossed, and 35 feeds the zone B decrement (Py) or increment (Px) to the counters via OR-gates. When the Y-count in 34  reaches Ym, output 36 therefrom signals 35 and causes a circuit 37 to interchange the outputs of 31 and the inputs to 33, 34. Circuit 16 stores the first scanned point in zone B (vector ##) and circuit 22 corrects this to obtain the last scanned point in zone A for the plotter. In the embodiment of Figs. 3 and 6 (not shown) zones A and B are bounded by the lines X=Xm, X=Xm (D2), Y=Ym and Y=Ym (D3), and the vectors #, ## extend alternately and in the appropriate directions along lines connecting (Xm, Ym) to points on D2, D3 spaced by Px, Py respectively.

Abstract: 823,300. Stacking machines. BERNER A. B., C. March 14, 1957 [March 21, 1956], No. 8442/57. Class 94(1). [Also in Group XXX] In an elevator, which can be used for stacking boxes or transferring them from one conveyer to another at a different level, the boxes are raised by pawls 8 pivoted on vertically reciprocating rods 7 on the upstroke and are retained by supports 13 mounted on the framework 1 on the downstroke. Each rod 7 is mounted on a vertical shaft 4 which is reciprocated by the double-acting piston of a compressed air cylinder 6. The pawls 8 tend to take the position shown in Fig. 1, but on the downstroke they are swung upwardly either by contacting the boxes 3 or by means of studs 9 on shafts 10 mounted on the rods 7 and reciprocated by compressed air cylinder mechanism 11. Resilient rollers 12 on the pawls 8 facilitate movement along the sides of the boxes. The pawls 13 are moved out of the path of the boxes by pins 14 on a vertically reciprocating shaft 15. When the boxes are to be transferred to an upper conveyer, the upper conveyer is provided with two carriages 20, 21, Fig. 3, provided with rollers 22 and having wheels 23 running on rails 24. The carriages are moved apart by piston-andcylinder mechanism 25 to allow the top box 3 to pass through the conveyer and are then brought together by the same mechanism to support the box as the stacking mechanism moves downward. All carriers 8 and supports 13 may be put out of action except the lowest ones. A stack fed into the machine may be broken down by providing pivoted members 28, Fig. 1, on the framework 1 which are adapted to engage the handles of the boxes. In use the stack is raised until the members 28 engage the box which is second from the bottom. The lowest box is then lowered until it rests on the conveyer 2 by which it is carried away.
