Title: Turbocharged diesel engine with stepped gearing to compressor - allows variation in speed of crankshaft-driven displacement compressor adjusted automatically in accordance with engine temp.
Inventor: MAILAENDER UDO DIPL ING
IPC: F02M31/07
Filed: 1991-08-29
Abstract: The engine (10) is doubly supercharged by an exhaust-driven turbocompressor (22, 20) and a displacement-type compressor (19) which is coupled to the crankshaft (24) by gearing (29) stepped automatically (35) in response to measurement of combustion chamber wall temp. (36). The first gear (25) affording the greatest speed ratio is used for engine starting, and the last gear (28) for fuel economy. At low air pressure the heat required for compression-ignition is abstracted by a heat exchanger (17) from the exhaust gas flow (21) to the silencer (23). ADVANTAGE - Engine power is increased with reductions in fuel consumption and pollutant emission.

Title: Antilocking brake control circuit for motor vehicle -  uses wheel-spin detector and signals from non-driven wheels exclusively if wheel-spin occurs
Inventor: SAKANE SHINSUKE
IPC: B60T8/58
Filed: 1991-09-09
Abstract: Wheel-speed sensors (5) are used on the driven and undriven wheels. The signals from all the sensors and integrated and compared with reference values.

Title: Sliver can position lock - has holding locks moving up through can plate to hold plate and can rollers
Inventor: KOEPPLER HORST
IPC: B65H54/80
Filed: 1991-09-16
Abstract: To hold a sliver can in place, where the can has rollers for movement, the can plate (2) is at the same height as the adjacent frame level with no vertical can plate movement. The holding locks move upwards from below the can plate (2) to engage through it. On a can change, the locks pref. are retracted below the level of the can plate (2). The locking units are spaced from each other by the layout of the can rollers, to cover the swing radius of the separate rollers, to engage the can rollers when they are projected through the can plate (2) and above it. Where the sliver cans have no running rollers, sliding rails (3) are fitted to the can plate (2) in a star layout, radiating from the centre to the outer edge, with at least three holding locks between the sliding rails (3) round the circumference of the can plate (2), to be lowered below the level of the sliding rails (3) on a can change. ADVANTAGE - The mechanism keeps the sliver can firmly in place while it is being rotated for filling with sliver, such as at a drawing unit to prepare the sliver for spinning, without using energy to lift a can plate and the weight of a full sliver can.

Filed: 1992-05-26
Abstract: A virtual machine system having a plurality of virtual machines, in which each virtual machine can be relocated to a now storage area of main storage without interfering with any other virtual machine. The relocation is carried out by move instructions issued by a service processor 5 upon receipt of a relocate command. These instructions pass control to a controlling section 6 which instructs a logical instruction processor (LIP) controlling section 7 to temporarily stop the LIP of the particular virtual machine. Next a check is made by the resource managing section 8 to determine whether the virtual machine can be moved. Once that has been checked, the virtual machine is relocated on the main storage area in accordance with a designated address by the relocate command and the controlling section 7 restores operation of the virtual machine. <IMAGE>

Patent DE-4220490-A1 (DE)
Inventor: DREYER HANS DIPL ING
IPC: B29D30/14
Filed: 1992-06-23
Abstract: In the building of a tyre blank in a tyre building machine, the individual components of the tyre blank are applied by corresponding feed devices, such as ply feeders or the like, onto a building drum and in the process are subjected to treatment by suitable treatment devices, such as ply rolling-down devices, attachment rollers and splicing rollers. If these treatment devices are specially designed for the respective treatment steps, they require a relatively high outlay. A universally applicable pressing roller is therefore to be used, which is provided with a multiplicity of disks which are displaceable with respect to one another and, on a shaft, radially with respect to the building drum. The shaft is located in a mount by means of which it is adjustable radially with respect to the building drum. The disks are identical to one another. Each disk comprises an inner part and an outer ring surrounding said inner part via a ball bearing. A rectangular recess is made in the inner part, with the lateral surfaces of which it slides on the lateral surfaces of the shaft, which is rectangular in cross-section. In the top and bottom displacement volume formed between the top and bottom surface of the recess on the one hand and the corresponding surfaces of the shaft on the other hand, there is disposed a displacement tube into which a pressure medium can be admitted. <IMAGE>

Title: Long chain methyl alkyl ether cpds. prodn. by hydrogenating formal - using palladium@ catalyst with phosphoric acid catalyst to increase yield
Inventor: HEES UDO
IPC: C07C41/28
Filed: 1992-06-26
Abstract: Prodn. of methyl alkyl ethers of the formula R1-0-CH3 (I); R1 = 6-22C aliphatic hydrocarbyl with 0-3 double bonds; comprises hydrogenation of formals of the formula R1-O-CH2-R1 (II) in the presence of Pd catalysts (III) and H3PO4. Specifically R1 = 12-18C alkyl. Pref. hydrogenation is carried out at 150-250 deg.C and 10-100 bar, using 0.1-5 (wt.)% (III) and 0.1-5% H3PO4 w.r.t. (II) and a Pd:H3PO4 ratio of 1:10 to 10:1. USE/ADVANTAGE - Dialkyl ethers are raw materials e.g. for lubricants and cosmetic formulations. Satisfactory yields are obtd. by using H3PO4 as cocatalyst, whereas yields from (II) with long alkyl chains are unsatisfactory with (III) alone. The process also avoids the formation of large quantities of salt, as in the Williamson method, and poor selectivity and the formation of olefins in the etherification of alcohols in the presence of strong acids.
