Title: Control of valve mechanism of internal-combustion engines
IPC: F01L1/348
Filed: 1938-02-24
Abstract: 511,853. Valve,gear; regulating. READ, B. Feb. 24, 1938, No. 5835. [Class 7 (vi)] In an engine having two camshafts driven (1) each through a pair of intermediate gears, or (2) by chain gearing with three intermediate sprockets, the angular relationship of both cam shafts is adjusted so as to vary the overall inlet or exhaust period, or both, by (1) moving both intermediate gears about the axes of their driving and driven shafts, or (2) arranging the intermediate sprockets so that two of them can be positively moved, while the third is moved automatically by a spring. Fig. 1 shows two cam shafts 11, 12, the former driven from the crankshaft 13 by gear wheels 14-17, and the latter by gear wheels, 14, 18, 19, 20. The wheels 15, 18 are carried by arms 21, 22 pivoting about the crank shaft 13, and the wheels 16, 19 by arms 23, 24 pivoting about their respective cam shafts, the pairs of intermediate wheels being also connected together by links 25, 26. The arms 21, 22 are adjusted by links 27, 28 so as to bring the centres of the wheels 15, 18 to other positions by adjustment about the crank shaft, for example, to positions 15<1>, 181, thereby advancing and retarding the two cam shafts 11, 12, respectively. The links 27, 28 may be connected to a piston 64 acted on by the pressure of the lubricating-oil, so as to adjust the cam shafts automatically. In the chain gearing drive, the chain passes round sprockets on the crank shaft and on the two cam shafts, two idle pulleys, one at each side of the crank shaft sprocket being simultaneously adjusted, for example, by the piston 64. Fig. 5 shows a valve 56 actuated from both cam shafts through push rods 60, 61 and rockers 57, 58 which engage at opposite sides of a third rocker 59, the centre of which rests on a spherical member 62 mounted to slide across the end of the valve stem. Specifications 511,903 and 511,904 are referred to.

Abstract: 514,234. Telescopic props. WIGLEY, A. F. Feb. 23, 1939, No. 6035. [Classes 20 (i) and 20 (ii)] A telescopic prop of the kind comprising an inner tubular member 2 provided with a plurality of holes to receive a cross pin 4 which is supported on a screw threaded sleeve 3, adapted to coact with a screw thread cut on a thickened portion at the upper end of the outer tubular member 1, which is a slotted extension to receive the cross pin of the inner sliding member, has the slot provided in an upper extension of the outer tubular member to prevent weakening of the prop. The length of the thread in the sleeve exceeds the threaded portion of the tube 1 by an extent which is at least equal to the length of the slot, thus preventing exposure of the thread during adjustment. A bifurcated end fitting with a pintle may be fitted in either end of the prop which is normally provided with a flat plate

Abstract: 894,022. Cutting by fusion. UNITED STATES STEEL CORPORATION. Feb. 23, 1960 [March 12, 1959], No. 6369/60. Class 83 (4). [Also in Group XXIII] A rolled section beam 12 is positioned on a roller conveyer 10 by photo-electric cell means 23 which, on arrival of the beam at a predetermined position, stop the conveyer motor 11 and the beam is then cut to length by a torch 13. A light source 18 and four photo-cells 19, 20, 21, 22 control relays 25, 27, 28, 29 and are adjustably mounted so that the length cut can be varied. The first relay 25 is de-energized when the light falling on cell 19 is interrupted by the end of the beam 12 and it shunts a resistor 17a in the motor field circuit to slow down the motor. The beam continues to advance until it interrupts the light to the cell 20 and the de-energized relay 27 causes contaets 14a, 14b to open and stop the motor. Through a slow-acting relay, the torch is advanced to cut the work and is automatically returned. If the beam overshoots, relay 28 or 29 is operated and the motor 11 returns the beam at fast or slow speed until it is stopped when relay 28 is again energized. Switches are provided for operation of the conveyer at maximum forward or reverse speeds, by-passing the photo-cell control, and a take-off section 10a is constantly driven at a faster speed than the main conveyer by a motor 39.

Abstract: 823,231. Electronic counting apparatus. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. March 1, 1956, No. 6469/56. Class 106 (1). [Also in Group XL (b)] A ring counter comprises transistors T1-T5, which are normally " on " (large current flow) but switched " off " one at a time sequentially and which may control gates G1-G5 so as to form a distributer, each transistor having a connection between its collector and the base electrodes of each of the other transistors so that when it is "off" it holds the others " on " and a coupling C9-C9 between its collector and the base of the next transistor so that when it goes " on," the next one is switched off ". If, say, the transistor T1 is " off," the consequent low potential of its collector applied over a resistance connected to the base of the transistor T2 and, via the point 1 and the resistance shown as connected to that point, to the base electrodes of the transistors T3- T5, maintains all of the other transistors " on ". However, a clamping voltage B1-applied over a rectifier D6 maintains the collector potential of the "off " transistor T1 at such a value that when this transistor is switched " on " by an advancing pulse (negative) from a common source, applied over a condenser C1 and a rectifier D1, to the base of the transistor, the resulting pulse passed by the condenser C6 due to the rise in the collector potential will be sufficient to switch the next transistor T2 " off ". Further advancing pulses step the counter on in a similar manner. The gates G1-G5 may pass serial signals read from a store into parallel channels.

Abstract: 945,433. Tubular heat exchangers. BABCOCK & WILCOX Ltd. Feb. 22, 1961 [Feb. 25, A tubulous heat exchanger comprises a pressure vessel containing a tube-bank comprising two or more mutually interposed groups of tubes which extend to and from tube plates or internal headers, the latter providing for fluid flow through each group such that each group has its own inlet and its own outlet chamber. Fig. 2 shows such a pressure vessel 2 having headers 1 each divided into two chambers 1A and 1B. Fluid flows from the inlet chamber 1A to the outlet chamber 1B via the horizontal layers of U-shaped tubes 7, adjacent tube layers extending from different headers. The axial pitching of the holes in the headers which receive the tubes is greater than the circumferential pitching. In the heat exchanger shown in Fig. 4 tube plates 13 are formed across each end of the pressure vessel, the space between the plates and the walls of the vessel being divided by a partition 3 into inlet and outlet chambers in flow connection with each other via the tubes 7. In each case, the second heat exchange fluid flows through the vessel between branches 15, and supports 11 are provided to space the tubes 7 from each other and from the walls of the vessel.
