Title: Piston seals for master brake cylinder - with L profile circular segments pressing on seals to take up piston clearance
Inventor: VALPREDA LUIGI
IPC: B60T11/20
Filed: 1976-07-22
Abstract: The master brake cylinder has two pistons (10, 70) held apart by a first spring (58) to form a first pressure chamber. The second piston (70) is spaced from the end of the cylinder by a second spring (258) to form a second pressure chamber. To provide a simple design of piston each piston has the pressure end with a stepped profile, and with a loose fit in the cylinder bore. Special L-profile curved segments (45) are located over the wider steps and serve to support the rearside of the elastic piston seals (46). This compensates for the loose fit of piston. The system enables a simple process to be used for the mass production of the pistons and bores.

Title: Precise repeatable photographic exposure operations - using scale representing base format and enlargement which is independent of focal length
Inventor: SIEGEL HANS
IPC: G03B27/72
Filed: 1976-08-05
Abstract: Method for performing precise repeatable exposure operations, for close-range photography for reproduction, enlargement and reduction, is carried out by producing a scale independent of focal length for the compulsory base of a format, and measuring factor V steps (distance lengthening and shortening) directly from the size of working masters. For the compulsory base of a negative transparency format, a scale is produced by which factor V steps can be measured directly from the degree of image adjustments according to the base, at the optical image. In this way, factor V steps can be read directly without time-consuming scarcely accessible measurement and calculation, to allow precise repetition of exposure operations of the same category without the need for photoelectric cell measurement.

Title: High-speed hydrodynamic hammer with built-in container - having elastic diaphragm which cooperates with vertically adjustable and horizontally movable die block
Inventor: BRONIN GEORGY KONSTANTINOVITSC
IPC: B21D26/06
Filed: 1977-01-04
Abstract: The hammer includes a working chamber with a container having a bottom portion of elastic material, a die block which is reciprocable horizontally into and out of the chamber and a hydraulic cylinder for displacing the die block toward the bottom of the container. An impact head comprises a hollow separating bushing rigidly and coaxially affixed within a housing which define an annular space there between. A sleeve is mounted for reciprocation within the bushing and a plunger is mounted for vertical reciprocation within the sleeve. Impact of the plunger on a deforming medium within the container deforms the elastic bottom of the container to shape the blank mounted on the die block in conformance with the latter. Used for pressing and forging equipment for stamping or forging metal sheets. The hammer develops a deforming effort as high as 2,000 to 2,500 kg/cm2 and is equivalent to a static press with a 7,000 ton effort while the wt. of the hammer is only 1/8th to 1/10th of the static press. The efficiency factor of the impact of the hammer is 4 - 6 times as great as that of electro-hydraulic stamping and explosion stamping.

Title: Zero correction system for analogue-stochastic converter - uses integrator connected to converter output during correction periods
Inventor: SEIBT ARTUR DR ING
IPC: H03M1/00
Filed: 1977-06-20
Abstract: The converter has a multiplexing device as an input switch delivering a zero signal to the converter at sufficiently frequent time intervals. All circuit parts connected to the converter output are disconnected during the zeroing period. The output signal of the converter is applied to an integrator (VR) whose output signals are transmitted to the highest binary counter stages of an adder (AD) for combination of the address word for the noise generator (RG) digital-analogue converter (DAW) with the correction signals. As a result the digital-analogue converter (DAW) delivers to the analogue-stochastic converter (ASU) an additional current compensating the zero error.

Title: Hydraulic control system for waste collecting vehicles - moves push-out wall with motion indirectly controlled by pressure element
Inventor: LEISSE NORBERT
IPC: B65F3/28
Filed: 1977-08-13
Abstract: A hydraulic control system is for a bulk goods container such as waste collecting vehicles. There is a push-out wall hydraulically movable inside the container and with a pressure element which pushes the material filled in between the wall and the pressure element against the push out wall.
