Title: Pneumatic spring biased vehicle brake cylinder - has piston sealed between spring and air chamber with limiting stop
Inventor: MUELLER WOLFGANG DIPL ING
IPC: B60T17/08
Filed: 1975-07-21
Abstract: The pneumatic braking cylinder for a vehicle is designed especially for spring-loaded and/or service brakes. It has a piston between a pressure chamber and a spring chamber, sealed from each other. The spring-loading and air pressure are in opposition, and brake release is caused by reduction in air pressure. The piston stroke is limited by ledge (7), which produces an upper bound to braking force. In the case of service brakes, there is an additional chamber to prevent total vacuum on braking. There is also a relief valve with a ball and spring, preventing excessive pressure in the spring chamber.

Title: Corona discharge foil surface treatment - has foil drawn between pair of charged electrodes of which one has quartz coating
Inventor: AHLBRANDT ANDREAS DIPL ING
IPC: H01T19/00
Filed: 1975-11-12
Abstract: To improve the bonding qualities of foils, sheets or plastic shaped parts, their surface is pre-treated by corona discharge. Instead of a set of stationary and rotating electrodes only a set of stationary electrodes are used with a permanent coating of quartz. The electrode itself is a metal body with the quartz coating fused-on. The electrode can be shaped to handle workpieces with poorly accessible corners. During the operation the temp. of the quartz coating may increase to a critical point, where the quartz loses its insulating capability and cooling by air stream has to be applied.

Title: Optical cell classification system - passes biological cells through split components of laser beam with different characteristics
Inventor: FULWYLER MACK J
IPC: G01N21/64
Filed: 1975-11-14
Abstract: The method is used for the classification of biological cells which respond to incident light by absorption, dispersion, or fluorescence. A laser beam containing wanted and unwanted wavelengths is split into separate beams having different characteristics, and the cells are passed through the different beams so that their response to the different beams is observed. The degree of response of the cells to each beam is recorded as a basis for classification. The system is especially applicable to the examination of vaginal smears, where cancerous cells have optical characteristics differing from those of normal cells.

Title: Regulated twenty four volt battery fed power supply - uses twelve or twenty four volt battery connected either way to produce stabilized output
Inventor: STUEDLI RUDOLF
IPC: H02M3/337
Filed: 1976-02-11
Abstract: A twenty four volt output voltage regulator is fed from a 12 or 24 volt battery supply, which can be connected to the regulator without regard to polarity. The regulator contains an input polarity correction unit comprising a diode and relay, which supply 12 volts to a transistor inverter with the correct polarity. The inverter output, taken from a transformer and diode rectifier pair, is fed to a transistor 12V regulator and out put stage which is in turn connected in series with the input polarity corrected 12V battery supply, to provide the 24V output required.

Title: Water heater with heat exchanger coupled to boiler - and located at bottom of cold water heating vessel beneath auxiliary electrical heater
Inventor: BIRNBREIER HERMANN DIPL PHYS
IPC: F24H1/20
Filed: 1976-06-05
Abstract: The water heater consists of a heating chamber (4) into which cold water is fed through an inlet pipe (6) at its top. A heat exchanger (7) is located at the bottom of the chamber and is connected to a boiler. Water circulates between boiler and exchanger and transfers its heat to the water in the chamber. An electrical heater (10) is mounted horizontally in the chamber above the heat exchanger and partially screened (18) from the latter. When the boiler or solar collector is not in use or too low the water in the chamber is heated by the electrical heater. Because this heater is above the heat exchanger no heat is transferred back to the water in the exchanger.

Patent DE-2634397-A1 (DE)
Inventor: SATO YUKIO
IPC: B23B7/06
Filed: 1976-07-30
Abstract: The automatic multi-tool lathe is constructed for selectively putting a selected number of tool holders (17) into operation in the radial direction with regard to the workpiece (13) in the form of a wire or a rod, which is carried by a headstock (14) in a rotatable manner and - relative to the tool holders - in an axially movable manner. Each of the tool holders is normally held in its rest position and is put into its maximum advanced position by pressurising of an allocated hydraulic cylinder unit (35). The speed and the degree of advance of the respective tool holder is profile-controlled by a cam plate (42) which can be rotated in angular motion about the axis of the workpiece and has a cam surface on which an arm (32) projecting from each of the tool holders acts. In such a lathe, the control of all tool holders can be carried out by a single cam. In this arrangement, the path length of the power transmission between the cam and the tool holders can also be minimised. <IMAGE>

Title: Refractory lined rotary kiln - with conical section rings inside shell taking up axial thrust from lining expansion (OE150277)
Inventor: LANDTHALER ANTON DIPL ING
IPC: F27B7/28
Filed: 1976-09-27
Abstract: The shell of a high temp. kiln or oven carries internal rings of conical section. In the region of these rings the refractory bricks of the lining are correspondingly conical faced on one side to bear against the support ring. Pref. at intervals along the inner surface of the kiln there are affixed metal rings of conical section, the angle of the cone w.r.t. the kiln wall being about 20 degrees. Radial distance pieces support the inner edge of the cone from the shell wall. In the region of these support rings the refractory bricks also have correspondingly angled faces which mate with the cone angle. Axial thrust from the adjacent bricks of the lining bears against the concial faces and is converted into radial pressures transmitted harmlessly through the radial supports into the shell wall. A simple and reliable way of absorbing the axial thrust which takes place on bringing the kiln to operating temp. without causing unwanted stresses in the material or fittings of the kiln.
