Patent DE-2334661-A1 (DE)
Title: Multi-spindle automatic lathe - employes angularly successive chisel type tools to improve high speed component stability
Inventor: ARUTJUNOWITSCH SCHAUMIAN GRIGO
IPC: B23B29/24
Filed: 1973-07-07
Abstract: The cutting tools in the form of chisels are fitted in chisel blocks which are fixed rigidly to the machine body at a constant angular distance from each other around the rotor. The angular distance between the chisel blocks differs from the angular distance between the spindles for the workpieces on the rotor by a value which is a multiple of the ratio of the angle of contact between chisel and workpiece to the number of chisel blocks. The workpieces come into contact with the chisels one after another during rotation of the rotor.
Patent DE-2340732-A1 (DE)
Title: Steel rod cutting shear - balance arm lowered with material weld in position by gas pressure spring
Inventor: PEDDINGHAUS CARL ULLRICH DR
IPC: B21D43/28
Filed: 1973-08-11
Abstract: Sheat for material which moves longitudinally and is to be cut transversely, especially for steel rods, has an exit roller track for the further transport of the cut material. The start of the roller track is in the form of a balance arm, which can be lowered with the material to be cut and then returned into its horizontal position after the cut. The balance arm is held in its position on the machine frame by a hydraulically damped gas pressure spring. The squeeze out pressure of the spring is sufficient to support the balance arm in the horizontal position. Its push in path relates to the lowering of the material through the top blade.
Patent DE-2341068-A1 (DE)
Title: Bicycles lighting circuit with generator and batteries - has plug connecting lights to generator and batteries, and shorting out protective resistor
Inventor: NEWMAN JAMES JOSEPH
IPC: B62J6/00
Filed: 1973-08-14
Abstract: The lighting circuit, for bicycles, has its generator (driven by one of the wheels) charging the Ni-Cd batteries via a rectifier, a first switch and a protective resistor. The resistor prevents the generator fom over-charging the batteries. One pole of the generator, the batteries and the front end rear lights is 'earthed'. When the lights are required 'on' a plug is inserted between two spring contacts so that the first switch is open-circuited -- thus cutting out the resistor -- and the lights are supplied both from the batteries and the generator. One of these spring contacts is connected to the rectifier output and the other directly to the 'unearthed' poles of the batteries.

Title: Stackable container without lid - has internal ribs on two walls, fitting in outside grooves when empty
Inventor: FREDRICK WILLIAM H
IPC: B65D21/04
Filed: 1973-09-13
Abstract: The square-section plastic container has vertical ribs on the inside of opposite walls, and is particularly for the transport of packed items of foodstuffs, e.g. boxes of eggs. The walls have locking devices at top and bottom, used when full containers are stacked on top of each other. The two other walls have grooves on the outside, accommodating the ribs when the empty containers are stacked, after rotation through 90 deg. in relation to each other. The containers can be made from relative hard, though still bendable, material since the dimensions and distances between the flat edges of the rib structure can be greater than usual. A smaller bending of the side walls can be reckoned with.

Title: Self loading container lorry - with guide rails for rollers under container and section of track lowered to secure load
Inventor: BERGER GERD
IPC: B60P1/64
Filed: 1973-09-28
Abstract: The rear surface of the container lorry is fitted with horizontal guide rails which engage the front edge of the container where there are fitted rollers. The rear edge of the container is supported on the ground by folding struts. The lorry backs under the container with the rollers rolling on the rails. When the container reaches the front of the rails a section of rail on each side drops on a hinge to secure the rollers and drop the container onto the rails. The ground struts are then retracted, and the weight on the rollers is relieved for travel. To drop the container the track section is raised hydraulically and the lorry driven away from the container, supported over the ground on the folding struts.

Title: Special projector for frontal projection of transparencies and films - uses lenses of fixed or variable focal point
Inventor: LEHMANN FRITZ
IPC: G03B21/20
Filed: 1974-04-25
Abstract: The projector is mounted to swivel on a point where a vertical and a horizontal axis intersect an optical axis.

Title: Beading or folding press for sheets of paper plastics film etc. - has mobile beading or folding rail operated by cam-controlled lever
Inventor: THIES FRIEDHELM
IPC: B65H45/18
Filed: 1974-07-26
Abstract: A beading or folding machine for sheets of paper, plastics film or the like, has a folding rail ('sword') that may be moved up and down in a jib and is operated by a cam-controlled lever supported in the jib. The cam-operated lever engages the folding rail and is spring-loaded (i.e., equipped with springs), near its swivel axis, against its support. The claimed arrangement enables the dimensions (and hence the weights) of the moving machine parts to be kept at a minimum. Thus, the folding machine can be of relatively lightweight construction.

Title: Folding bed or table fitting - has two fixing plates with inter linking type arms for folded or continuous surface
Inventor: KURZ RICHARD
IPC: E05D3/06
Filed: 1974-12-24

Title: Drilling mud specific gravity meter - with thermometer probe between two vertically spaced pressure sensors
Inventor: DOCKHORN WOLFGANG
IPC: G01N9/26
Filed: 1975-02-19
Abstract: The specific gravity of drilling mud in oil and gas drilling operations is measured by arranging above the blowout preventer a pipe with two pressure sensors at different levels to measure the drilling mud pressure. A thermometer probe between the sensors measures the temp. and the specific gravity is calculated from the pressure difference and the temp. This system is accurate enough for a rapid correction of even slight alterations in the specific gravity of the drilling mud which may endanger the well.
