Title: Road vehicle hydraulic brake - has valve in main piston allowing actuation of auxiliary one under low pressure
Inventor: STOKA ROBERTO
IPC: F16D65/18
Filed: 1980-04-30
Abstract: The hydraulic brake is used in a road vehicle. It comprises a piston working in a cylinder and actuating a shoe, the piston being divided into a main one (12,12') containing an auxiliary one (13) sliding in a cylinder (11) parallel to it. The main piston contains a valve (14) in the path (18,19,20) of the hydraulic fluid under pressure, and which remains open where pressure is insufficient to move the main one, the auxiliary one being actuated instead. Above a predetermined threshold value, occurring shortly before the main piston starts to move, this valve shuts, confining the fluid in the auxiliary cylinder (11).

Title: Stiff door lock handle - can be withdrawn for multi finger grip without affecting closing mechanism
Inventor: LEGER FRIEDRICH DIPL ING
IPC: E05B5/04
Filed: 1980-09-26
Abstract: The handle, turned from outside, protrudes only slightly from the door front face in its basic position and/or is partially sunk in this. The handle supports a spindle on the side facing the inside of the door for transmission of its rotary motion to a closing mechanism, in a lock on a door. When mounted, the handle (11) is withdrawable from its basic position, axially from the lock, far enough to be gripped and operated with more than two fingers, without affecting the position and effectiveness of the closing mechanism. The spindle (18) may deviate from the circular in cross-sectional shape, and be guided so as to be axially displaceable in a fitting recess (38) on the closing mechanism. This makes it easier to open a door which may be jammed or is difficult to open for any other reason.
Patent DE-3037156-A1 (DE)
Inventor: ELTZ HANS-ULRICH VON DER DIPL
IPC: D06B23/26
Filed: 1980-10-01
Abstract: In order to maintain at a constant value the quantity of liquor applied in the wet-on-wet application of two liquors of differing composition, it is necessary that the fabric web which is wet from the preceding wet treatment is first uniformly partially dewatered and the second liquor is then applied uniformly. By using high-moisture measuring instruments after the dewatering and also controlling the same with the aid of measured values, and by proceeding similarly after the repeated application of liquor, it is possible to stay within the tolerances which are necessary to ensure the uniformity of the two processes.

Title: Heterogeneous ligand-contg. carrier and complex catalyst prepn. - by pretreating carrier with silane or oligomeric silicate before bonding ligand
Inventor: HAHN KARL DR
IPC: B01J31/24
Filed: 1980-11-11
Abstract: Heterogeneous ligand-contg. carriers and complex catalysts contain inorganic carriers, ligand-bearing cpds. fixed to carrier surface and opt. form complex with transition metals. The carriers and catalysts are prepd. by (1) reacting a carrier, contg. OH gps. on surface, with an Si cpd. having formula -SiXQ- (I) (where X is a functional gp. capable of reacting the carrier OH gp. to form siloxane gps. and Q is a ligand-bearing gp.) and (2) opt. reacting the modified carrier with a transition metal cpd. Alternatively, (3), the carrier contg. OH gps. on surface is reacted with an Si cpd. having formula -SiXW- (II) (where W is a ligand-bearing gp. bonded to form a complex with a transition metal). Improvement comprises using a non-porous or macroporous carrier having average pore size 10-500nm. Before treatment with (I) or (II), the carrier is treated with 0.5-50 wt.%, w.r.t. carrier, of an Si cpd. having formula SiX4, (III), or RSiX3 (IV) (where R is alkyl, cycloalkyl or aryl) or an ester of oligomeric silicic acids with lower alkanols, at 0-100 deg.C. The ligand-contg. carriers can be used to separate transition metal ions or cpds. from solns. The catalysts can be used for hydrogenation, carbonylation, carboxylation, hydrosilylation, metathesis, oligomerisation and polymerisation.
Patent DE-3044154-A1 (DE)
Title: Motor regulating system using microcomputer - uses phase angle and pulse width signals for fine and coarse control in computing system
Inventor: STAERK JAKOB DIPL ING
IPC: H02P23/22
Filed: 1980-11-24
Abstract: The method of regulating the operating voltage of electric motors uses control signals obtained by superimposing two signals of different frequences, and one of the signals at least is varied. One signal which controls the phase cut off angle of the operation voltage is the phase angle signal. The other signal, which is the pulse width signal, controls the pulse width of the operating voltage. This gives coarse control, and the phase angle signal gives fine control. The actual value of the motor speed is compared with a nominal value and the difference gives the variation of the control signal. The nominal value is stored in a microcomputer connected by a data collection line with a tachometer counter with its contents corresponding to the actual motor speed. The two control signals are connected by respective registers with the computer and an equalising circuit is connected between the register and a frequency divider chain receiving clock pulse signals.

Title: Pneumatic drive unit for producing a reciprocating movement of a drive shaft
IPC: F01L25/06
Filed: 1981-07-10
Abstract: A pneumatic drive unit for producing a reciprocating movement of a drive shaft, especially for the actuation of windscreen wipers in buses and heavy trucks, is characterised by a segment shaped, compression-resistant housing, which is divided into two chambers by a swivel piston fixed on a drive shaft. Each of the two chambers is connected by way of a ventilation and venting duct and a control duct to a valve unit. The control ducts are each closed by a spring-operated valve, which is opened by the swivel piston in that limit position in which the assigned chamber has the maximum volume. In addition the valve unit has a double acting piston capable of sliding to and fro in a housing, which piston can be locked in either limit position by a locking device. The control ducts each lead to chambers of the valve unit separated by the piston and when pressure is admitted lead to reversal of the piston into its other limit position in which the ventilation and venting duct of the chamber just then having the maximum volume is connected to the surroundings and the ventilation and venting duct of the other chamber, which just then has the minimum volume is connected to a compressed air source.
