Patent DE-2721555-A1 (DE)
Title: Power assisted steering system - has main and auxiliary circuits controlled by plungers and sliding valve respectively
Inventor: JABLONSKY ERICH
IPC: B62D6/02
Filed: 1977-05-13
Abstract: The system has two separate hydraulic circuits. The first circuit is intended for normal driving conditions and the second circuit supplements the first circuit for heavy duty requirements. The first servo piston receives hydraulic pressure from a first pump in response to steering wheel movements to act on the steering box gear. The second servo piston acts on the steering rod and receives pressure from a second pump. The first circuit is controlled by two plungers arranged transversely to the steering shaft axis and responding to steering wheel movements. The second circuit is controlled by a sliding valve. The regulator slots in the first circuit control plungers are smaller than the corresponding sliding valve slots.

Title: Infinitely variable gearing for motor or turbine - has oscillating arm connected to one way coupling through spring accommodating output torque resistance
Inventor: LAAKKO MIKKO ANTERO
IPC: F16H29/08
Filed: 1977-11-26
Abstract: The infinitely variable gearing has a pivotal arm (9) which is oscillated by an eccentric (8) mounted on an input shaft (7). The free end of the arm is connected by a tension spring (10) to the free end of a lever (4) connected to an output shaft (1) through a one-way coupling (5). Oscillation of the arm is therefore converted into rotation of the output shaft. The transmission ratio is varied by the torque resistance of the output shaft, i.e. increasing resistance is accommodated by increasing extension of the spring.

Title: Pouring metal without turbulence into thin walled mould - gradually lowered into cooling bath during casting from horizontal into vertical position (SW 22.5.78)
Inventor: BERGGRUND RUNE
IPC: B22D23/00
Filed: 1978-02-18
Abstract: In the initial stage of pouring, the molten metal flows along a horizontal path into a mould which ismounted on a horizontal pivot just above the surface of the cooling bath, and as pouring proceeds, the mould is swivelled downwards through an angle of approx. 90 degrees so it is completely immersed in the bath and in a vertical position at the end of casting. The swivel motion of the mould is pref. achieved due to the increasing wt. of molten metal and using a controlled speed. In the pref. plant, the metal flows into a distributor mounted on a swivel and fitted with an outlet gutter of pipe which swivels together with the mould. The distributor pref. has two outlet runners used for the alternate filling of two moulds, each of the latter being mounted on a swivel. The cast metal is free of slag and oxide inclusions etc.

Title: Blank sheet enclosed inside sealed envelope - has visible writing produced by typewriter pressure (PT 21.6.78)
Inventor: ROBERT JACQUES
IPC: B41L1/32
Filed: 1978-02-23
Abstract: A sealed envelope encloses a blank sheet of paper (12). The front panel of the envelope is also provided with a transparent window (3). The two narrow sides (7) on the envelope edge are perforated (8) and they form guides when the continuous strip of envelopes is folded to a zig-zag stack. When a typewriter without ink ribbon is used to write a message onto the enclosed sheet (12) it produces visible print on the enclosed sheet due to the type pressure, without leaving any visible marks on the outside of the envelope. The address typed within the window space is visible due to its transparency.
Patent DE-2817395-A1 (DE)
Title: Composite, solid-rubber tyre - comprising two prestressed half-tyres fitted side by side whose running-surface crests are forced apart when under load
Inventor: HARTMANN KARL VON
IPC: B60C7/10
Filed: 1978-04-20
Abstract: Motor vehicle solid rubber tyre comprises two symmetric massive half-tyres which are pretensioned w.r.t. each other in the radial central plane of the tyre. They have flat inner walls with the outer walls parallel to them. Inner and outer walls of each half-tyre are connected via a half-tread which subtends an acute angle with the inner wall. The pretensioning of the massive half-tyres is effected in such a way that, having regard to a predetermined, expected, laden wt. of the vehicle, the half-tyres are spread apart in the central plane at least in the region between crest of tread and wheel felloe. Usage characteristics of the composite tyre, as claimed, approach those of conventional tubeless tyres, in addn. to those afforded by solid-rubber tyres.

Title: Anchor bolt with expansible sleeve - having projections which are annealed to spread when bolt is tightened
Inventor: HARRIS FREDERICK J
IPC: F16B13/06
Filed: 1978-06-16
Abstract: The anchor bolt comprises a bolt portion (4) with a conical end (3) and an intermediate smaller diameter portion which carries a two part expansible sleeve (2). The sleeve is formed with projections (5). The portion (3) and sleeve are entered into a hole in concrete or masonry and, on tightening, the portion (3) expands the sleeve to anchor the bolt in the hole. The sleeve is of material having a hardness in excess of 230 Brinell and in its manufacture the projections are annealed to have a hardness of between 100 and 230 Brinell. In consequence they flatten when the bolt is tightened and spread the load.

Title: Coke oven machinery de-centralised control - according to stored program from one master machine
Inventor: TESCHNER WOLFGANG DIPL ING
IPC: C10B41/00
Filed: 1978-08-02
Abstract: In the decentralised control of the coordinated function of all coke oven battery machines, the program control units of all machines are located on the machines themselves. The coke pushing machine is pref. regarded as the master unit and is equipped with sensors for the synchronizing marks for every over chamber. It transmits control signals to the other machines via radio or inductive loop and initiates all functions after the correct positioning has been confirmed. The data processing on the machines themselves reduces the data flow density and improves the response time. Lucid controls are present on all machines, and alterations or extensions are readily accommodated by the modular design.
Patent DE-2847932-A1 (DE)
Title: Chain drive sprocket for track-laying vehicle - has elastic layer between tooth surface and core to allow elastic movement of teeth to accommodate track deformation
Inventor: MARWITZ HARTMUT DR
IPC: F16H55/30
Filed: 1978-11-04
Abstract: The drive sprockets have teeth which are capable of elastic deformation, similar to the deformation which occurs at the chain link bolts due to the rubber fill material. The teeth pref. are built up of three layers, a core which is integral with the material of the sprocket itself, an elastic layer and a hard upper coating which defines the outer contour of the teeth. The teeth cores are distributed at the correct intervals around the sprocket corresponding to the average pitch of the chain links. Because of the elastic layer, the teeth are able to deform with the effect that a stretching of the chain will be accompanied by a corresponding increase of the pitch of the teeth.

Abstract: Free emergency phone calls are cleared by the called unit, in case the caller forgets to hang up. The caller may be on an electronic or an electromechanical exchange, which require different clearing signals. These are sent alternately, each for 150 ms with 150 ms pause between them. A clock (1) generates a square wave, 150 ms ON, 150 ms OFF, which drives two switches (i1,i2) and two bistable changeovers (f11,f12), i.e. the switches operate and the bistables change over every pulse. One bistable (f11) switches between -ve supply, -UB, and E and is connected to the a-wire by one switch (i1). The other bistable (f12) switches between (E) and (O/C)and is connected to the b-wire by the other switch (i2).
