Patent DE-2649685-A1 (DE)
Title: Chemical vapour deposition onto substrates such as tool sheet - using two vessels so substrate is kept below gas reaction temp.
Inventor: HOELLER ROLF
IPC: C23C16/08
Filed: 1976-10-29
Abstract: The substrate is located in a vessel (2) which is separated from the reaction vessel (1). The two vessels (1,2) are connected to each other, but the substrate is held at a temp lower than the reaction temp. of the gases in vessel (1). The reaction of the gases pref. occurs in a stream of carrier gas; and the pref. starting materials are metal acetyl-acetones; metal carbonyls; or metal halides. Tools made of high speed steel or a sec.-hardened, ledeburitic chromium steel can be surface hardened to over 60 HRc with TiC at 500 degrees C., i.e. below the normal tempering temp. for these steels.

Title: Centrally controlled telephone exchange - has automatic recall facility and uses call stacking registers with priority coding
Inventor: NICKEL HORST ING GRAD
IPC: H04Q3/54
Filed: 1976-12-24
Abstract: The centrally-controlled telephone exchange system with automatic recall facility for engaged subscribers consists of a space or time-multiplexed coupling field (KF) with associated connecting circuits and exchange line repeaters (AU 1) all controlled via a central controller (ZST). All lines are assigned a priority classification and given authorization identification codes which are held in a store in the central controller. The "free" or "busy" status of the connection is also held. A second store has positions accessible to the called party and functions as a call stacker. The priority status of each calling station is checked and addresses (called number) of each required connection are registered. The calling party receives either the "engaged" signal or a special signal to indicate that his call is being stacked.

Title: Multistage stepwise controlled automatic telephone system unit - is assigned to each first group selector, identifies caller and authorisation and sends dialling tone
Inventor: EWEN JOERG DIPL ING
IPC: H04Q3/00
Filed: 1977-02-09
Abstract: Additional units for multistage automatic telephone systems are allocated to each first group selector. A control switch in the additional device initiates at its first step identification of the caller when its allocated group selector is engaged, and controls the storage of the identified number in a working store (ASp) in the unit. In a second step the control switch reads out from a large store the entitlement of the identified subscriber, and stores it also in the working store. In a third step the control switch sends the dialling tone to the calling subscriber. The unit has a dialling receiver (WAe which receives and recognises the incoming dialling signals and transmits them through a dialling pulse generator (WS) to the group selector.

Title: Seismic method for investigating mineral structure - boring holes and forcing water into them so that mechanical, acoustic and electric pulses can be detected upon reflection
Inventor: MEININGHAUS FRITZ DR ING
IPC: G01V3/08
Filed: 1977-02-21
Abstract: In a seismic method for investigating the position and potential relationship of layers of mineral, holes are bored in the mineral bodies to be investigated. Water under pressure is forced into the boreholes and by this means mechanical, acoustic and electrical impulses are induced and detected after reflection. The hydraulic impulses may be varied from light to very strong pulse strength. Their rate may range from a single pulse per minute to several thousand. Both of these variants may be employed at pressures from one to several hundred atmospheres. Chemical additives, e.g. salt or detergent, may be dissolved in the hydraulic water.
Patent DE-2713208-A1 (DE)
Title: Resilient laminated wood batten for furniture - has required rigidity but extra elasticity in areas subject to deformation
Inventor: MUNK EDMUND
IPC: A47C23/06
Filed: 1977-03-25
Abstract: The resilient batten made of laminated wood and having increased rigidity, is used in the manufacture of beds, couches and similar furniture. It consists of several sheets of wood veneer which have been coated with glue and pressed together with the application of heat and pressure. The natural fibre runs longitudinally and the cross-section of the batten increases towards the centre from both ends. In this way, whilst retaining the required rigidity there is greater elasticity in the areas liable to permanent deformation so that the latter can be eliminated. The resilient batten can have a constant thickness although its width decreases from the centre to the ends. Alternatively it can have a constant width with its thickness decreasing from the centre to the ends.
Patent DE-2719666-A1 (DE)
Title: Digital lap speed display for model race track - is actuated by car striking switch at start and end of lap
Inventor: KILIAN HELMUT
IPC: A63H18/00
Filed: 1977-05-03
Abstract: A digital display unit (4) using light emitting diodes is used to display the time required for the model car (5) to cover one lap of the course. A chronometer (1) is connected to two switches (2) and (3) and to the digital display unit. Whilst the unit is operating, switch (3) is closed and switch (2) is open. As the toy car passes switch (2) it closes and starts the chronometer (1) with the time displayed on the digital display unit (4). At the end of a lap the car strikes the switch a second time but in this case opens the switch which stops the chronometer and displays the lap time.
Patent DE-2722947-A1 (DE)
Title: Electrostatic copier with integrated controls - has second switch, triggered by movement of original, opening starting circuit for exposure and charging stations
Inventor: JAHN GUENTHER ING GRAD
IPC: G03G15/28
Filed: 1977-05-20
Abstract: An electrophotographic copier has a reciprocating carriage for the original to be copied and an automatic feed system to carry the sensitive material through charging, exposure, and developing stations. A starting switch sends a pulse to start the movement of the carriage for the original and the motor for the transport and exposure of the sensitive material. A second switch, triggered by the movement of the original, opens the starting switch circuit and applies current to the exposure and charging stations. The return of the original to the starting position closes the starting switch circuit ready for a second cycle. The motor is switched off through a time delay element to ensure the completion of the copying cycle.

Title: Facia assembly for dimmer switch - covers box buried in plaster allowing for wallpaper thickness without control spindle alteration (NL 13.8.79)
Inventor: STUMPF HEINRICH
IPC: H02G3/18
Filed: 1978-02-09

Title: Road manhole cover adjustable in height - has two level serration on inner frame and single outer frame indentation
Inventor: HILD MANFRED
IPC: E02D29/14
Filed: 1978-02-11
Abstract: The shaft of manhole cover is readily adaptable to a different road level in the event of application of new layer of bitumen and has a fixed outer frame, and an inner frame carrying the lid. The inner frame has a complete vertically aligned serration profile, with teeth alternately terminating on two different parallel rising planes(1, A, B, C, D). The outer frame, with corresponding negative indentations, only completely bears the upper mounting plane(2, C, D). According to turning and height-setting of the inner frame, the outer one first accommodates this upper plane, and the lower one is gradually brought to bear. With load-bearing capacity maintained, the outer frame's width and weight are reduced.
