Patent DE-2547490-A1 (DE)
Title: Rolling mill with hydraulic prevention of roll flexure - using row of hydraulic cylinders to support each work roll
Inventor: THEOBALD WALTER
IPC: B21B13/14
Filed: 1975-10-23
Abstract: The work rolls are prevented from flexure by hydraulic pressure. In one pref. rolling mill, the work rolls are mounted in stands fitted with traverses, each traverse contg. a row of hydraulic cylinders with pistons pressing on balls or small rollers. The balls or rollers are pressed against the roll barrel over the entire length of the roll and thus prevent its flexure. Alternatively, the work rolls are supported by back-up rolls, and the hydraulic pressure is applied along the back-up rolls. The dia. of the work rolls can be reduced, because the hydraulic pressure prevents bending or flexure of the rolls.

Title: Pressure control valve for vaporizer - situated in vehicle air conditioning system component working with valve seat
Inventor: JACYNO HENRY
IPC: F25B41/04
Filed: 1975-10-30
Abstract: The pressure control valve has the valve seat situated between the inlet and outlet parts of the housing, the control element being on the outlet side. The control element surface is exposed to the inlet pressure. It comprises a pressure capsule (46) on the valve seat (32) outlet side, with one end fixed and the other connected to the control element (34). The pressure inside the capsule keeps the control element on the seat until the inlet pressure exceeds the force generated by the capsule. The proper functioning is not adversely affected by dirt or dampness in the cooling agent. Should it cease to function no further disadvantages follow as a consequence.

The appts. consists of a vessel contg. pipes with electrodes between coolers and gas spaces through which the gas is transferred from the coolers to the pipes.
Patent DE-2551632-A1 (DE)
Inventor: FLANAGAN JAMES LOTON
IPC: G10L13/06
Filed: 1975-11-18
Abstract: Disclosed is a system for synthesizing emphasis-controlled speech from stored signals representative of words precoded by a phase vocoder having analysis bands which are wide relative to the voice harmonic frequency spacings. The stored signals comprise short-time Fourier transform parameters which describe the magnitude and the phase derivative of the short-time speech spectrum. Speech emphasis-controlled synthesis is achieved by extracting the stored signals of chosen words under control of a pitch-duration signal, by concatenating the extracted signals, by modifying the magnitude parameters of the extracted signals to effect a desired speech intensity, by interpolating the extracted parameters, and by decoding the resultant signals in accordance with phase vocoder techniques.

Title: Anti blocking control for pneumatic brakes - with pressure compensation for relay valve for rapid pressure rise
Inventor: REMBOLD HELMUT DIPL ING
IPC: B60T8/36
Filed: 1975-12-12
Abstract: The pneumatic brakes are fitted with a relay control valve which separates the brake supply valve from the wheel cylinders. A pressure reservoir (32) is supplied from the brake line via a non return valve so that a supply is available for cyclic braking. The brake control valve is a simple 3/2 valve which connects the reservoir to the input of the relay via a second non return valve (34). This enables the brake pressure to be raised at an enhanced rate after venting, so that rapid brake cycling is obtained.

Title: Counting arrangement for axle and wheel of rail vehicles - uses coil system with open field near identification point to generate magnetic field for passing metal detection
Inventor: BESZEDICS GEZA
IPC: B61L1/16
Filed: 1977-04-06
Abstract: The axle and/or wheel counting arrangement is applicable to railed vehicles. It evaluates the passing of metal objects by an identification point. A coil system (E) in a combination of a.c. circuits (EAK) generates an alternating electromagnetic field. It is near, but not in contact with the identification point. Change of the open circuit coil system (E) impedance caused by the object to be identified, is evaluated for selective pulse generation. In normal working the feed-back (R) maintains the frequency correction at the generator (G). This is ensured by a blocking element (S) making the feed-back (R) ineffective for the duration of the ANN'S (U) output signals.

Title: Manually operated flowable material dispenser - has outer housing surrounding readily deformable inner container holding material to be dispensed
Inventor: SZCZEPANSKI HARRY
IPC: B65D83/00
Filed: 1977-04-29
Abstract: The dispenser for flowable materials has an outer housing surrounding a readily deformable inner container holding the material to be dispensed. The housing is resiliently deformable under manually applied forces, and has an air inlet covered by the hand of the user, or controlled by a check-valve providing for inflow exclusively. Constriction or compression of the housing by hand increases the pressure of the air occupying the space between the housing and the inner container, compressing the inner container, and expelling some of the contents via an outlet. Release of gripping pressure permits the resiliency of the housing to restore its original configuration.
