Title: Process control computer for simple applications - uses pocket calculator chip for arithmetic functions and separate cycle control unit
Inventor: JARES JOSEF
IPC: G06F19/00
Filed: 1975-10-17
Abstract: A process controller consists of a main cycle control unit operating together with a computer unit to perform any detailed arithmetic operation. A pocket calculator module is intended for this latter junction. Typically data is processed over a bus (6) and in particular data and instructions entered into a store (10). Decoded data (11) is supplied over an input (12) to the pocket calculator chip (13). Any output from the calculator is decobed (17) and entered into a buffer memory (15). The cycle control (16) co-ordinates the operation of the units and the processing of interrupts etc. By providing separate cycle control and computational facility, any arithmetic process may proceed at the relatively slow speed possible with calculator chips without disadvantage.

Title: Bending tool for circuit board wires - has series or coaxial tapering bores in sections having stepped outer walls of length of grid cells
Inventor: ROZEK SIGMAR
IPC: H05K13/02
Filed: 1976-01-21

Title: Packaging container with advertisements - encourages reuse by affixing printed advertisements on container to minimise wastage of natural resources
Inventor: WILCKE GERHARD
IPC: G09F23/00
Filed: 1976-02-20
Abstract: It is proposed that containers for consumable items should be used in a dual role; firstly as a container for transportation and secondly as a reusable container with advertisements on the outer surface. Since the container is no longer intended for single use, the contruction is more substantial with the higher production costs being offset by the advertising revenue. The intention is to reduce the amount of wastage of natural materials by re-cycling. A specific example is the return of container to data processing establishments using fast printers for tabulated output.
Patent DE-2608954-A1 (DE)
Title: Compensator of interference caused by external magnetic fields - uses two deflection systems inside electron microscope controlled by external sensors
Inventor: ANGER KLAUS DIPL ING
IPC: H01J37/09
Filed: 1976-03-01
Abstract: An electron microscope has a device for compensating interferences to the beam path, caused by outer magnetic field. The compensation device has two sensors, mutually orthogonal and aligned at right angles to the axis of the electron microscope. The sensors respond to magnetic fields. Two field generators are energised in dependence on the sensors. The generators are energised via amplifiers and additional frequency responsive elements. They are aligned in the direction of the sensors, and affect the desired compensation. Preferably beam (9) deflection systems (15) inside the electron microscope act as the field generators. The systems are controlled by sensors (11), outside the microscope, and additionally via frequency responsive, phase-shifting elements.

Title: Vibration damper and heat sink for reciprocating saw - has axially and radially movable carrier guide controlled by eccentric
Inventor: RITZ ALAN J
IPC: B23D49/16
Filed: 1976-03-26
Abstract: The vibration damping and heat sink mechanism for a reciprocating hand-held saw has a carrier guide with limited axial and radial movement positively controlled by an eccentric. The carrier guide serves both as a counterweight and a heat sink. A drive shaft for the eccentric also drives a wobble mechanism for reciprocating a saw blade carrier slidably mounted in the carrier guide. The relative movement of the carrier guide with respect to the saw blade carrier and their relative weights are such that a perfect balance may be obtained when aggressive orbital action of the saw blade and saw blade carrier is used as in the case of cutting wood.

Abstract: Fluid sewage is delivered to an underground reservoir positioned in a water-holding strate. A perforated conduit extends through the strate surrounding the reservoir and encloses a circulating-fluid line. The relatively warm fluid sewage passes out of the reservoir into the surrounding strata and thence into the conduit where it warms the circulating fluid. The circulating fluid operates a heat pump used in conjunction with a heating or cooling system.

Title: Electrolytic prodn. of aluminium - from a fused salt mixture of aluminium chloride and a metal halide
Inventor: ICHIKAWA HACHIRO
IPC: C25C3/08

Abstract: The fused salt mixt. is composed of 2-15 wt.% AlCl3, 15-70 wt.% CaCl2 and/or MgCl2 and 83-15 wt.% NaCl, the ratio of MgCl2/NaCl being >=1. The cell is lined with a refractory material and graphite electrodes are used. Cl gas is evolved during electrolysis at the anode surface while Al collects at the cathode surface.
