Title: Improvements in the construction of bumper devices for vehicles
IPC: B60R19/04
Filed: 1954-04-23
Abstract: 750,382. Bumpers for vehicles. DAIMLERBENZ AKT.-GES. April 23, 1954 [April 24, 1953], No. 11828/54. Class 103 (2).

Title: Production of gases of high and low calorific value
IPC: C10B49/18
Filed: 1954-04-23
Abstract: 747,061. Distilling and gasifying coal and like fuels. UNION RHEINISCHE BRAUNKOHLEN KRAFTSTOFF AKT.-GES. April 23, 1954 [April 25, 1953], No. 11844/54. Class 55(1). In a process for obtaining both distillation gas and producer gas from coal and like fuels, the coal is destructively distilled with a solid heat carrier maintained in a cyclic current and the coke formed by the distillation is gasified to yield producer gas at a temperature such that the sensible heat of the producer gas is sufficient to heat the solid heat carrier and supply the heat required in the distillation. The heat carrier may be pellets of clay or metal or the coke formed in the destructive distillation may be used. In Fig. 1 particulate coal to be distilled is blown by a carrier gas onto the base of a distillation zone 2 through which a heated coarse-grained solid heat carrier is moving slowly from the top towards the bottom. The coal is distilled in passing upwardly through the heat carrier and coke and gas pass by line 3 to a separator 4. Distillation gas is withdrawn by line 5 and the separated coke is blown by cold air into a gasifier 8. Preheated air is admitted to gasifier 8 by line 7. The gasifier may be of the type described in Specification 666,119. Ash is withdrawn at 9 and hot producer gas flows by line 10 to a zone 11 in which it reheats the heat carrier. After leaving the zone 11 the producer gas is used to prevent air for the gasifier 8 in heat exchanger 13. Heat carrier is withdrawn from the distillation zone and conveyed by a bucket elevator 16 to the reheating zone 11. When the coke produced is used as the solid heat carrier a portion for example about 5 per cent of the coke withdrawn from the distillation zone is gasified and the resulting highly heated producer gas at about 1650‹C. is used to reheat the remainder of the coke withdrawn to a temperature of 1000‹C. In reheating the coke may be pneumatically conveyed by or fluidised by the producer gas and separated therefrom in a separator. From this separator the producer gas is used to preheat air for the gasifier and is again treated to remove entrained particles of coke. The latter may form the portion of the coke gasified in the gasifier. Fresh coal or a liquid fuel may also be gasified in the gasifier and a proportion of the producer gas may be led directly to the air preheater.

Title: Improvements in internal combustion engines
IPC: F02B19/02
Filed: 1925-05-07
Abstract: 234,088. Standard Development Co., (Assignees of Zaikowsky, W. M.). May 19, 1924, [Convention date]. Cylinders, clearance spaces of; charge, cooling; two- and fourstroke-cycle engines.- In an engine having a large compression ratio, charges are drawn in through the admission valve 13 for the whole of the suction strokes and part of each charge is forced into a supplementary chamber 16 during the compression strokes; by this means the charge in the chamber will eventually and during normal running be at a pressure which is above atmospheric pressure. The chamber is cooled by pipes 17 traversing the cooling jacket. The opening of the valve 12 is variable. Normally the valve is opened at the commencement and closed midway of the compression stroke; the volume of the chamber is equal to the piston displacement, so that when the valve 12 opens the cooled charge from the chamber enters the combustion space in sufficient quantity to prevent premature ignition and detonation. Two-stroke-cycle engines may work in a similar manner; for a multi-cylinder engine there may be only one, supplementary chamber connected by valved pipes to all the cylinders. For engines using heavy fuels the chamber is mounted directly over the cylinder to allow any unvaporized particles to flow from the chamber into the cylinder.

Title: Drive systems
IPC: H02P29/00
Filed: 1975-03-26
Abstract: 1499373 Control of D.C. motors LINDE AG 26 March 1975 [4 April 1974] 12587/75 Addition to 1380015 Heading H2J [Also in Division B7] A drive system particularly for a fork-lift truck comprises: a shunt-wound electric motor 22, 23 arranged to drive an output shaft 7<SP>1</SP> through an infinitely-variable transmission; current-varying means for varying the current flowing through the field winding 23 of the electric motor; and control means which controls the current-varying means in dependence on the power transmitted by the transmission in such manner that when the power transmitted reduces, the current flowing through the field winding 23 is increased and the speed of the electric motor consequently decreases. As illustrated, the infinitely-variable transmission comprises a variable-displacement hydraulic motor 7 connected by fluid lines 3, 4 with a variable-displacement hydraulic pump 2 driven through a shaft 24 by the electric motor. The current-varying means comprises a variable resistor 30 disposed in the electric line 29 leading to the field winding 23. The control means comprises control fluid lines 8, 9 connected to respective fluid lines 3, 4 and leading to a control valve 10 which connects that one of the two fluid lines 8, 9 which carries the higher pressure to a control line 14 leading to a servo-cylinder 15. A piston 32 of the servo-cylinder 15 is connected by a rod 16 to the variable resistor 30. When the pressure in fluid line 3 or 4 reduces, piston 32 is moved by biasing spring 31 so that the rod 16 reduces the resistance of the variable resistor 30. The increased electric current in the field winding 23 consequent upon the reduction in the resistance of the variable resistor 30 causes a reduction in the speed of the electric motor. A control lever 33 is operative to adjust the electric motor speed to a maximum irrespective of the load on hydraulic motor 7, for example when the motor 22 drives other powerconsuming devices, whereby operation of members 33, 34 overrides the control effect of members 15, 16, 31, 32. Members 33, 34 are also used to set the maximum desired speed of motors 7, 22, after which the motor 22 automatically controls the speed of the pump 2 whilst the transmission is adjusted to obtain a desired speed of the motor 7, whereby members 2, 7 always operate in the best efficiency range. In a further embodiment (not shown), the infinitely-variable transmission takes the form of an infinitely-variable V-belt transmission.
