Filed: 1925-11-18
Abstract: 262,576. Kane, R. W. H., (Goldschmidt, R.). Nov. 18, 1925 Percussive hand tools. - In reciprocatory mechanisms or tools, such as the mechanical hammer shown, in which the motion is produced by unbalanced centrifugal forces arising from the rotation of weights C driven through bevel gearing D and a slidable shaft E from a motor or driving shaft G, the usual power storing spring transmitting rotation from the driving shaft G to the shaft E is replaced by a centrifugally acting yielding coupling J. and/or the spring producing an axial force to opposing the upward throw of the weights E is similarly replaced by centrifugally acting masses M producing an axial thrust varying with the speed of drive. The centrifugal coupling comprises weights J pivoted at K to lugs on a sleeve H slidably keyed to the shaft E and located in a casing Y secured to the driving shaft G, pins S on the sides of the weights engaging slots L in the walls of the casing so that a torque is produced by the outward movements of the weights when subjected to centrifugal force. The masses M pivoted to the casing Y transmit an axial thrust to the shaft E through arms N, the forced ends of which engage arms P on a loose sleeve W adapted to bear against a collar Q on the shaft. Resilient rods R prevent rotation of the hammer head about its axis. The arrangement of the weights and levers may be modified.

Title: Improvements relating to thermionic valve circuits
IPC: H03F1/36
Filed: 1945-11-02
Abstract: 630,728. Valve amplifying and generating circuits. SIEMENS BROS. & CO., Ltd., BARTLETT, C. J. C., and MOSS, S. H. Nov. 2, 1945, No. 29156. [Class 40 (vi)] A resistance-coupled valve amplifier or generator comprises a multi-electrode valve with a load resistance in the cathode and anode circuits, the resistance values and the electrode potentials being chosen to produce a negative mutual conductance between the control grid and the anode. Fig. 1 shows a cathode coupled amplifier producing an output voltage in phase with the input voltage el. The critical value of cathode resistor Rc is derived in terms of the inter-electrode mutual conductances and electrode impedances from a mathematical expression quoted for the mutual conductance between the anode and control grid. A circuit, Fig. 3 (not shown), with a negative resistance between earth and the control grid or anode, may be obtained by employing cathode and screen coupling resistors according to the invention, and coupling the anode to the control grid by means of a capacitor with negligible impedance at the input frequency. In Fig. 3, a similar circuit without the screen coupling resistor maintains continuous oscillations in a parallel-tuned circuit LC, subject to the condition that the magnitude of the negative resistance is less than the dynamic resistance of the tuned circuit.

Title: Process for the separation of sludge from petroleum residues
IPC: C10G31/06
Filed: 1929-09-26
Abstract: Petroleum distillation residues, especially those obtained by cracking, are freed from dispersed and dissolved impurities causing sludging on standing or addition of other liquids, by diluting with pressure distillates or pressure distillate bottoms or liquids of analogous composition, and separating the sludge produced. Preferably a raised temperature up to 150 DEG  C., and 50-300 per cent by volume of the diluent, are used.  In examples, 1 litre of Dubbs residue is mixed with 1,0 or 2,5 or 3,0 litres of pressure distillate bottoms and heated in the water bath for 24 hours.  The Specification as open to inspection under Sect. 91 (3) (a) describes the separation of sludge from petroleum residues by liquids which dissolve the oil but not the sludge matters. Further diluents specified are petroleum fractions containing few aromatics, such as benzine, kerosene, and gas oil.  This subject-matter does not appear in the Specification as accepted.

Title: Hydro-pneumatic motor
IPC: A62B7/00
Filed: 1928-10-11
Abstract: 298,612. Compagnie Internationale des Freins Automatiques. Oct. 12, 1927, [Convention date]. Cam-actuated pumps; crank-actuated pumps; regulating delivery by opening suction valves; by stop valves.-In a hydro-pneumatic motor particularly for operating vehicle brakes, a pump forces liquid from a. discharge into a charge reservoir, the pump being rendered ineffective when the level or pressure in the charge or discharge reservoir reaches a predetermined value. As shown in Fig. 1, a pump 5 the delivery and suction strokes of which are respectively effected by a cam 11 on the vehicle axle and by a spring 5b is adapted to force liquid from a discharge reservoir 3 through passages 6, 7 into a closed charge reservoir 8. The suction valve 4a may be controlled by a magnet 4b in series with a switch controlled by manometer 8<c>, or by a float such as 8<b>, so that when the pressure or level of the liquid in the reservoir 8 reaches a predetermined value, the magnet is energized and holds the valve open. Alternatively, the supply to the pump may be controlled by a valve 3<d> operated by a diaphragm, as shown, or by a float in the reservoir 3. The valves 8<a>, 3<a> of the reservoirs 8, 3 are controlled by a switch 13 which has the following positions :-Releases position D ; tha magnets of both valves are energized, whereby the valve 3<a> is opened to permit liquid in the brake cylinder 26 to be returned by the spring 25<k> to the discharge reservoir 3; normal position M, in which both valves are closed; normal application position SS in which the valve 8a is deenergized and opens to supply the brake cylinder 26; emergency application position SU; in addition to the opening of the valve 8<a>, the valve 3<d> is held open. A passage 9 with a. small valve 3<h> enables the pressure, in the charge reservoir 8 to return to its normal valve after an emergency application. By opening a valve 10<a> the braking pressure may be established directly by the pump. To prevent the charge reservoir 8 from being completely emptied as by a number of consecutive applications of the brakes, the magnet of the release valve may, as shown, be connected in series with a switch controlled by a float 8<b> in the reservoir or by a manometer, so that it cannot be opened when the liquid is below a certain level. In another construction, the spring 5b is dispensed with and the return stroke of the pump is effected by the pressure of the liquid in the reservoir 3, the suction valve being spring loaded so that it ceases to open when the pressure is below a predetermined value. In a further construction, the pump is actuated by a crank and connecting-rod from the axle, through an electromagnetically actuated clutch controlled by a float in, or a manometer connected to, the reservoir 8, the clutch also being engaged for effecting an emergency application of the brake.

[Class 87 (i)] [Also in Group V] Prefabricated building-slabs simulating brickwork are made by means of an open pattern 23, Fig. 1, the spaces 24 of which are filled with plastic material such as sand and concrete to form blocks 27, Fig. 5, the pattern is removed and the recesses 30 left by the pattern are filled with a different plastic material to simulate mortar. The recesses may be filled by surrounding blocks 27, Fig. 5, by planks 28, and a backing 29 is thus also formed. The pattern 23 is placed on a template 20, Fig. 1, formed with ribs 21 registering with the bars of the pattern, and adapted to form depressions in the simulated mortar. The connection between the blocks 27 and the backing 29 is secured by wire hooks. The materials used for the blocks 27, in the recesses 30 and for the backing may all differ in character. In a modification the pattern is formed of brick-shaped blocks 44, Fig. 11, and the recesses 47 are filled first. Bricks, slabs or hollow tiles may be used in the backing. The pattern may form inlaid signs, letters, numbers &c. Asphaltic and bituminous material may be used, such as bitumen emulsion mixed with sand, gravel, flint and whinstone. The ends of the slabs may be formed stepwise following the pointing so that they can be interfitted. Specification 573,233 and 598,683 are referred to.

Title: Terminal equipment for a synchronized communication system
IPC: H04B7/155
Filed: 1973-06-22
Abstract: 1435146 Radio signalling RCA CORPORATION 22 June 1973 [10 July 1972] 29666/73 Heading H4L A television station 27, Fig. 2, is arranged to receive programmes via a satellite 3 originating in a remote station 5 and to combine these programmes with locally originated programs, means being provided to correct for delay variations due to orbital variations of the satellite. At station 5 a camera chain 7 supplies video signals to terminal equipment 9 receiving sync. signals from a generator 11 controlled via an adjustable phase-shifter 15 by a frequency standard 13. The resulting signal consisting of picture, sync, pulses and colour subcarrier is modulated on a carrier at 19 and transmitted to the satellite where it is retransmitted on a different carrier frequency to station 27. At station 27 the composite TV signal received at 31 is supplied via video equipment 35 to a special effects mixing amplifier 39 where certain portions of the raster of the signal from camera chain 45 via video equipment 49 may be replaced by portions of the signal from the station 5 or either signal may be selected. A second output of equipment 35 supplies the received colour burst signal to a colour subcarrier phase monitor 43. Video equipment 49 is controlled by a sync. generator 51, which the alternative position of switch 55 is controlled by a frequency standard 53. The colour subcarrier derived from standard 53 modulates the carrier wave at transmitter 63 and is returned via the satellite to receiver 31 where a separate reception channel supplies the delayed subcarrier via switch 55 to control the sync. generator 51. The two earth stations are near enough for the path length 23 plus 25 to be substantially equal to the path length 65 plus 25<SP>1</SP> so that only a small residual time delay adjustment will be necessary. In a modified arrangement for transmitting the subcarrier from station 27, which is preferable when the earth stations are more widely spaced, the colour subcarrier fc derived at 71, Fig. 4, from the frequency standard 69 is modulated at 75 by a frequency f 1  from an oscillator 87 and a filter 77 selects the upper sideband which modulates the transmitted carrier at 63. The return signal with a relative phase shift is received at 31 and the upper sideband is heterodyned with signal f 1  at 81, the resulting signal controlling sync. generator 51. The lower sideband of modulator 75 would be chosen if the path length between the local station and satellite is shorter than that between the remote station and satellite.

Title: Improvements relating to knitting machines
IPC: D04B13/00
Filed: 1934-10-17
Abstract: 430,637. Knitting-machines. HADDAN, R., 31, Bedford Street, Strand, London.- (Scott & Williams, Inc. ; 366, Broadway, New York, U.S.A.) Oct. 17, 1934, No. 29739. [Class 74 (ii)] The invention comprises means for feeding a yarn, means for varying the rate of feed, and means for stopping the machine when the rate of feed varies beyond predetermined limits, and it is shown applied to a garment tapering attachment for feeding rubberized yarn in between the needles to make tubular knitted fabric, Fig. 2, of varying circumference. The yarn 5 passes around a rod 40, through an open slot 42 on a guide member 41 and through a guide 43, whereby it is directed around a roller 10 rotating in a bracket 11, and between this roller 10 and a co-operating conical member 67 on a driven shaft 80. The yarn passes to a guide 44 and between the needles. The guides &c. 40, 42, 43 are supported by a plate 38 on a block 23, which is moved by a link 26 and a slotted lever 25 to different positions on a square bar 20 to cause the yarn to contact with different parts of the member 67 and thus vary its speed. The lever 25 is rocked about a pivot 31 on the bracket 32 by a part 34 adjustably secured to a slotted plate 35. The shaft 80 is supported on an arm 81 secured to the bracket 11 and to the bracket 32, which are supported by a bracket 57 bolted to the revolving base 56. A notched wheel 83 on the shaft 80 engages teeth 84 on the stationary cylinder 1 holding the needles 2, whereby the shaft 80 is rotated. Moreover, spokes 53 projecting from a screw 50 engaging a threaded shelf 54 on the plate 35 move past lugs 64, 65 on levers 60, 61 connected by flexible parts 73 to levers 71 pivoted to a fixed part 63 and controlled by pattern chains 76, 77. Either lug 64 or 65 can thus be raised into the path of the spokes 53, whereby the screw is turned, the plate 35 and part 34 raised or lowered, and the rate of feed of the yarn varied. The rate of variation is adjusted to make the taper of the tubular fabric more or less abrupt by adjusting the part 34 in a slot 36. Stop motions.-If the screw and plate 35 are moved beyond certain limits, one or the other of two hooks 89, 90 on a rod 86 on the plate 35 engages one of two pins 91 and rocks a part 93 pivoted at 94. This part then rocks and disengages a latch 100 freeing a stop member 105, which falls so that its free end 107 engages one of several elevations 111 on a shifting ring 110, which it operates to stop the machine.
