Title: Monitored locking device for railway points - uses sliding bar for control arm locking and monitor switch operation
Inventor: JESKE HANS-GEORG
IPC: B61L5/10
Filed: 1975-06-10
Abstract: A device for locking controllable points and crossings on railways can be used with switching mechanisms having locating and control slides in systems for high speed trains or shunting. The locking elements hold each control arm in its end positions to prevent unwanted reversals of point locations. Locking failure results in an indication. The locking arm (R) fits into recesses (A) in the control arm (U) of the switch drive (WA), and is moved by a locking drive mechanism (G). The locking mechanism is mounted in a housing (WR) attached to the switch drive (WA). The position of the locking arm (R) controls the position of switch contacts (WK) which are for locing position monitoring. The operating and locking elements may be driven electrically pneumatically, or hydraulically.

Title: Automatic monitoring equipment for e.g. respiration heart rate - with automatically adjusting threshold value discriminator for preselected comparative value ratio
Inventor: HOFMANN GERHARD DIPL ING
IPC: A61B5/08
Filed: 1975-06-20
Abstract: The automatic monitoring equipment is for physiological functions such as respiration, blood pressure, temperature, peripheral pulse, heart rate etc. A transformer continuously transforms the values of the monitored functions into analogous electrical signal voltages, and having a threshold value discriminator triggering an alarm (6) when the threshold value is not reached. There is circuitry to automatically adjust the discriminator to a pre-selected physiological and critically gauged ratio between the threshold value and a comparative value of the signal voltage. This is proportional to the monitored function relative to a just previously determined normal value and is maintained for the desired monitoring period.

Title: Control switch for HV gas blast circuit breaker - has two diaphragms, one controlled by inner pressure, operating two contact sets
Inventor: EGGERT HORST ING GRAD
IPC: H01H35/34
Filed: 1975-07-01
Abstract: The control switch for the high voltage gas blast circuit breaker operates in dependence on the gas density. It has a contact assembly under the effect of a diaphragm, whose force acts against a spring force. A contact volume of gas enclosed in a container operates the diaphragm. A second diaphragm, operated by the pressure inside the container, actuates a second contact assembly, the two contact assemblies switching at different pressure values. The pressure in the container inside is preferably lower than the operating pressure of the gas whose density is to be monitored. The two diaphragms may be of identical designs and stressed by springs of different forces.

Title: Moulding and extrusion method - for fluidising crushed powdered material which does not flow easily under gravity
Inventor: ATTWELL RONALD LESLIE
IPC: B28B1/52
Filed: 1975-08-29
Abstract: A method of fluidising crushed, pulverised, comminuted powdered or other particulate solids, with or without added liquid, that will not flow readily under gravity has been developed to enable this material to flow through an aperture either as an extrusion or to cause it to conform precisely to the shape of a mould. The material is inserted into the top of a hopper having an aperture at its base through which the material is discharged under gravity to a surface or into a mould. The material is subjected while in the hopper to one or more vibrators arranged to effect vibration of the material in the intended direction of flow through the hopper. This causes the material to flow freely through the hopper, and effecting relative movement between the hopper and a surface or mould to effect the withdrawal of the material discharged from the hopper.

Title: Structure investigation by optical correlation - using monochromatic light passed through correlator system with two optical lenses, filter and measuring diaphragm
Inventor: GREINER EGON DR RER NAT
IPC: G01N21/956
Filed: 1975-11-21
Abstract: A method for testing structures uses the principle of optical filtering. Monochromatic light is passed through a micro lens and microdiaphragm and condenser to a partially transparent structure and thence to a photoelectric receiver through a correlator system with two optical lenses and measuring diaphragm. The photoelectric receiver measures by spatial integration. The surface to be measured is twice as great as the smallest detail of the structure to be inspected. The system permits high sensitivity and reproducibility using optical and photoelectric components of moderate quality.

Title: Regenerative heat exchange for two air streams - having rotating hood divided into several sections
Inventor: KRITZLER GERHARD DIPL ING
IPC: F28D17/02
Filed: 1975-11-27
Abstract: Regenerative heat exchanger for heating >=2 parallel air or gas streams consists of a rotating hood over a fixed chamber of solid material for heat retention. The hood is one of a pair above and below the chamber and is divided into >=2 sections either side of a central axis. The flow area of each pair of sections is the same. These radiate from the centre where there are several concentric ducts for the various parallel gas or air streams. The hood and the central ducts are sealed from the hot exhaust gas flowing outside the hood by flexible seals. These are held in position by springs the tension of which can be adjusted. Device is of use in recovering heat from an exhaust gas stream where two or more temp. controlled air streams are required e.g. for preheating prim. and sec. air.

Title: Diesel or Otto engine cooled by methanol - which is vaporised to drive turbine to increase output and recycled to engine cooling jacket
Inventor: BRAUS KARL DR
IPC: F01K25/08
Filed: 1976-08-31
Abstract: A conventional internal combustion engine has its cooling jacket filled with methanol instead of water. The methanol evaporates in the cooling jacket and the vapour passes to a heat exchanger in which it is superheaded by the engine exhaust gases. The superheated vapour is expanded in a turbine and the discharge from this which is at low temp. and pressure is condensed in a water cooled heat exchanger. The liquid methanol flows into a receiver tank from which it is pumped back to the engine cooling jacket. The output of the turbine increases the total power obtained from the fuel burnt in the engine and thus increases the overall efficiency.
