Title: Adaptor for pipe section transformation - has gradual, steady change in perimeter segment size
Inventor: BURR KARL
IPC: F16L43/00
Filed: 1975-03-26
Abstract: The pipe adaptors are used in pipe lines, boiler installations etc., where it is necessary to change the through flow section from one shape to another. The adaptors can be either straight or curved to divert the flow direction if necessary. To make a square-to-circular adaptor, say, a square end template is placed on a baseplate, and the other end template of the adaptor, here a circle, is placed on a top plate. Both shapes are now divided into equal proportions and the dividing points of the two shapes are interconnected. The side pieces of the adaptor are now made to the shape enclosed by the connecting lines and the small sections of the end shapes.

Title: Thread rolling maachin for bolt mfr. - using rigid bed for the reciprocating slide carrying the moving thread-rolling die
Inventor: LEOPOLD WILHELM
IPC: B21H3/06
Filed: 1975-04-16
Abstract: Thread rolling machine has a slide bed with a surface inclined w.r.t. the horizontal, the bed being used for a reciprocating slide carrying the moving thread roll which works in conjunction with a stationary thread roll on a vertical rolling line, and with a bolt feeder. The novelty is that in order to absorb the horizontal thrust pressures the slide is mounted on two guide surfaces located at 90 degrees to each other and opening out towards the thread rolls, the two guide surfaces being inclined to match the slide. Greater support is provided for the slide so that the film of lubricant between the slide and its guide surfaces does not break down. The result is that the slide can be reciprocated at higher speeds than those possible with conventional machines.
Patent DE-2517097-A1 (DE)
Title: Time multiplex signal transmission network - has branches to which individual subscriber stations are connected
Inventor: PROEGLER MAX DIPL ING
IPC: H04M9/02
Filed: 1975-04-18
Abstract: A synchronisation word forming a time frame is delivered from a network point, and at extreme network points is transmitted through a delay line from reception to transmission line. The delay time is such that synchronisation words are simultaneously received in the next network junction point. Spacing between two synchronisation words is in each station divided in equal time slots, and the whole message transmitted over the transmission line is transferred to the reception line at a point. A subscriber station (B) which detects its message in a time slot on the transmission line, branches out the message for its evaluation. This time slot is erased, and a message is sent by the station (B) in the same slot to a different subscriber (A) which receives it exclusively on the reception line. The message is evaluated, and sent by subscriber (A) to (B) in the same time slot.

Title: Electrophotographic copier with HV development electrode - has two part photoconducting image region which controls development electrode loading
Inventor: MOCHIZUKI MANABU
IPC: G03G15/047
Filed: 1975-08-07
Abstract: An electro photographic photocopying device has a photoconducting member with an image region and an additional region. They are moved together with a development electrode and a potential is applied to the development electrode (14) when the image region (10a) of the photoconducting member (10) lies above it. The development electrode (14) is then earthed when the additional region (10b) of the photoconducting member (10) is moved to a position above the development electrode (14). Before earthing of the development electrode (14) the additional region (10b) is given a potential load which is equal to a second potential of the background region of the image section (10a) of the photoconducting member (10).
Patent DE-2536321-A1 (DE)
Title: Fibrous or flaky material fed into mould - by sudden compression in cylinder then expansion into mould
Inventor: RUPPIN DIETRICH PROF DR ING
IPC: B27N5/02
Filed: 1975-08-12
Abstract: A method of filling a hollow mould of any geometry with fibres, dust or chips, constituting a matl. having a low bulk density and capable of compaction. The matl. to be introduced into the mould is contained in a cylinder and is projected forwards by a violent impulse of the piston, which produces an adiabatic compacting impact in the matl.; continuing in its passage into the mould, the matl. passes through an expansion nozzle. Pref., the mould has an internal pressure other than atmospheric during the filling stage. The mould and/or cylinder and/or expansion nozzle may contain gases having an adiabatic exponent different from that of air. Advantages are: no additional air requiring removal from the mould; extremely short mould filling times; precompaction of the matl. in the mould takes place, thus reducing the stroke required in the press for precompaction and the overall height of the press; improved quality of the prod., since the contact time with the mould can be very short; matl. reaches all parts of the mould regardless of its geometry.

Title: Safety clip for pivotal chain link - is sheet metal strip bent in loops and hinged to retain hook over pivot pin
Inventor: MERKLE PAUL
IPC: F16B2/24
Filed: 1975-08-22
Abstract: The safety clip is for a pivotal link, e.g. a chain link with two side hooks, one fixed to, and the other removable from two pivot pins. It comprises a sheet metal strip having a first hook (m) bent (f) and hinged about the fixed pin (d) and a second part (l) bent (f') and hooked around the removable pin. The blank clip has a fold (e) at the inside of the fixed pin so that the clip remains on the fixed pin when the first hook is bent around the outside of the pin. This facilitates the subsequent bending of the second part of the clip around the removable pin.
Patent DE-2539562-A1 (DE)
Title: Reservoir for heated windscreen washers - has heat from reservoir conducted along water pipes to keep nozzles free of ice
Inventor: KORF OTTO
IPC: B60S1/50
Filed: 1975-09-05
Abstract: The reservoir for the windscreen washers is heated and insulated by a protective coating. The water lines between the washer jets and the reservoir are of heat conducting material so that heat is transferred to the jets to prevent freezing. The jets are mounted directly on the wiper blades so that water losses are kept to a minimum, especially heated water. The blades are thus warmed and do not collect ice layers. The system provides safe winter driving and eliminates the need for ice scrapers, which can also damage the glass.

Title: Gear wheel type hydraulic pump - has rotating outer annular wheel with split spacer piece between gears
Inventor: REICHERT FRIEDRICH ING GRAD
IPC: F04C2/10
Filed: 1976-04-01
Abstract: The pump has an outer wheel with gear teeth on the inside. This meshes with a pinion on the inside of the outer wheel whose centre is offset from that of the outer wheel. The outer wheel is driven by a chain or gear drive from outside. The twisting moment produced by this is taken up by radial and axial bearings on the pump flange. A spacer piece between the two gears on the side opposite to that on which they mesh is constructed in two halves (a, b) which spigot together and are forced apart by a spring to fill the gap and keep the gears in mesh. This provides automatic compensation for wear and improves the pump performance.

Title: Excitation controller for small synchronous motor - uses CMOS output amplifier to switch field current
Inventor: OGIHARA MASUO
IPC: H02P25/022
Filed: 1976-05-21
Abstract: A single CMOS amplifier (6) is emplyed which receives an input (Q) from an oscillator setting the motor speed. The field winding (11) is connected between the amplifier output and one pole of the d.c. power supply (9) with a series capacitor (12) included. For zero signal input to the amplifier the current flow (25) charges the capacitor from the supply thereby producing a current pulse in the field winding. With an amplifier input the supply is blocked and the capacitor discharges (26) giving a reverse pulse through the windings. Thus an alternating flux is set up.
