Title: Improvements in rotary compressed air motors
IPC: F04C14/00
Filed: 1944-12-22
Abstract: 587,262. Rotary engines. HOLMAN BROS., Ltd., and ARTHUR, J. Dec. 22, 1944, No. 25717. [Class 110 (ii)] An outwardly-sliding vane type of engine, actuated by compressed air,or other gas, is reversed, started, stopped and its speed regulated by means of one handle 11 which operates a rotary valve 16 and has silencing means for the exhaust. Fig. 6 shows the fullyopen position, air passing from an inlet 18, through aligned ports 13, 19, passages 15, 24 into a, cylinder 9 where the air moves a piston 4 which is coupled by a pin 6 to a partiallyrotatable sleeve 2. Air passes from the passage 15 to a further passage 15a leading to inlet chambers 14 and one or other of the latter is connected to the working chamber by a port in the sleeve 2 being in alignment with a port in a liner 1. A slide valve 35 controls the air supply to the working-chamber and is acted on by a centrifugal governor 34. In Fig. 7, air may pass through the left-hand port 13 to a passage 20, port 21 and passage 22 leading to the passage 24 and so to the cylinder 5 of the piston valve 4 before the main inlet 13 is opened. This ensures that the required inlet port to the working chamber is open before the main air supply is admitted. Air exhausted from the cylinder 5 passes to a duct 26 to an expansion chamber 28 having perforated, sound-absorbing linings 29. A spring-pressed detent 33 holds the handle 11 in the position it is placed in.

Title: Improvements in hydraulic drop hammers
IPC: B21J7/36
Filed: 1952-10-15
Abstract: 729,941. Hydraulic drop hammers. LANGENSTEIN UND SCHEMANN AKT.-GES. Oct. 15, 1952 [Oct. 29, 1951], No. 25819/52. Class 83 (4). In a drop hammer whose hammer head 4 is raised by pressure liquid supplied to the underside of a piston 2 and is allowed to fall upon the opening of a return shut-off valve 20 which is closed when the hammer head has fallen, the closing of the valve is effected in dependence upon the striking of a work-piece by the hammer head. The valve may be closed by a device of the kind disclosed in Specification 721,335. The pressure liquid is supplied by a pump 8 which is running continuously, the liquid being by-passed through a pipe 12 by a valve 13 when the piston has been raised. The pump may be of the constant delivery or variable delivery type. A spring-loaded accumulator piston 18 in the supply pipe 7 acts as a shock-absorber. The return shut-off valve 20 is of large bore so as to allow the hammer head to drop freely; a release valve 22 of small bore allows the hammer to fall slowly. Air is compressed in the top of the cylinder to cushion the upstroke. A vacuum is prevented from occurring in each end of the working cylinder 1 by valves 6, 24. A spring may be compressed by the piston during its upstroke.

Directive signalling; thermionic relays. - In order to remove the 180‹ ambiguity, the directional apparatus of the kind described in the parent Specification is combined with a non- directional aerial 1 voltages from which are applied through amplifiers 2, 2<a> to a coil 3, which is coupled in turn through an amplifier 4 to a resistance 5 inserted in the anode circuit of a cathode-ray oscillograph 7 so as to modify the discharge stream. Or a resistance such as 5 may be inserted between the anode of the oscillograph and the leak resistances connected to the de flecting-plates of the oscillograph; or between the cathode of the oscillograph and a control electrode or grid inserted between the cathode and anode. Or, as shown in Fig. 4, the voltages from the unidirectional aerial may be applied to a coil 11 to create an axial magnetic field, which in turn controls the focal distance of the ionic beam passing through the deflector plates 9 of the oscillngraph. Or the non-directional voltages may be applied to the filament of the oscillograph so as to control the electron emission. In such arrangements the relative brightness of the indicating spot indicates the true direction of the received signals. Fig. 5 shows the complete installation. Directional voltages from the aerials NS, EW are applied to the corresponding deflection plates of the oscillograph 7 through tuning, amplifying, filtering, frequency-changing, and phase-adjusting means AN, AE of known type, whilst AV represents similar means for controlling the voltages received by the non-directional aerial and applied for example to the control-electrode 10 of the oscillograph.

Patent GB-263237-A (GB)
Abstract: 263,237. National Cash Register Co., Ltd., (National Cash Register Co.). Sept. 23,1925. Cash registers; item counters; voucher.issuing; multiplying-apparatus.-A cash register is provided with multiplying means whereby an item may be entered a number of times, with denomination selection, this number being counted and indicated. This item-counting mechanism serves also to count the number of items entered at any stage of an ordinary multiple-item transaction. The invention is described as applied to a key set and operated machine as set forth in Specification 142,436. In one arrangement (Fig. 2) the totalizer 70 is axially displaceable by means of a finger piece 170 so that it may be positioned with its units wheel or its tens wheel opposite the units actuator thus enabling an item to be entered with its nominal value or with ten times that value. An extension 171 of the totalizer frame co-operates with a pair of notches 172 in a fixed plate so as to justify the totalizer in either of its lateral positions. To count and indicate the number of times an item is entered, counting wheels 151. Figs. 6, 5, are adapted to be operated by pawls 154 connected with arms 166 secured respectively to a shaft 167 and a surrounding sleeve 182. When the totalizer frame 65 is rocked for receiving an item a pin 169 or 180, depending upon the lateral position of the totalizer, rocks the shaft 167 or sleeve 182 to disable one of the pawls, the other pawl being free to actuate its wheel when the pawl lever 155 is rocked from the key coupler. In the second form of the invention the totalizer is not capable of lateral movement but the key-rocked actuators are connected by cross-shafts 202 (Figs. 15, 16) with pinions 203 axially slidable to mesh with three of the five actuators 204 adapted to engage the totalizer. Thus by positioning a frame 210 enclosing the pinions 203 the actuation derived from the keys is transmitted to any three successive denominations of the totalizer from the units upwards. The frame 210 is notched to permit movement of the three selected actuators only and is shifted by means of a finger piece 214 displaceable along a numbered slot. The counting wheels 151 are selectively operated by a single pawl 216 connected with the frame 210 and operated from the couple by a long pin 220. When the invention is applied to a machine fitted with a grand totalizer it is necessary to disable this latter during multiplying operations. For this purpose a push key may be employed and may be connected with a type-wheel so as to cause a symbol to be printed against all items of multiplication.
