Title: Timepiece zero resetting mechanism for minutes hand - has manual pushbutton for resetting minutes hand on the hour
Inventor: HETTICH HUGO
IPC: G04B27/00
Filed: 1975-12-19
Abstract: The timepiece has a zero-resetting mechanism for the minutes hand, which allows the latter to be returned to zero when the hours band is positioned on the hour. The resulting mechanism employs a manual push-button having a pin (5) which can slide within the timepiece housing. The pin is biased outwards by a return spring (6). The push-button head (1) is attached to its outer end. The other end of the pin (5) is conical or divided and cooperates with a V-shaped peripheral notch (4) formed in a disc (3) attached to the shaft of the minutes hand, to bring the minutes hand to the 12 o'clock position. The disc (3) may have a second diametrically opposed notch (4') for bringing the minutes hand to the 6 o'clock position, for resetting the half-hour.

Title: Balanced organic-mineral fertiliser - contg. animal dung, rock flour and kieserite
Inventor: PETER MARTIN
IPC: C05F3/00
Filed: 1976-03-13
Abstract: Organic-mineral fertiliser, for all agricultural and horticultural crop plants (esp. difficult food plants), has a harmonic content of constituents with plant-physiological activity and consists of a mixt. of animal dung, rock flour and kieserite. The combination of rock flour and kieserite binds the water content of the animal dung (esp. poultry manure), bringing biological processes to a halt and eliminating adour and similar problems without actually killing the microbes contained in the dung. Since poultry manure is generally low in magnesium, addn. of the Mg-contg. kieserite converts it into a balance fertiliser.

Title: Fractional HP motor for pump drive - has aligned and assembled components bonded in correct position
Inventor: DOCHTERMAN RICHARD WAYNE
IPC: F04D29/62
Filed: 1976-04-01
Abstract: The application is principally to pumps for domestic equipment, for example washing machines. An accurate alignment of rotor (17) relative to stator (12) bore to give equal air gaps is maintained by a separate tool. The pump endplate (41) complete with shaft seal (51) and bearing (49) is assembled onto the rotor shaft and similarly held in correct alignment. The pump endplate is then fastened to the motor end bracket (54) and locked in position by bonding with a resin. A similar process can be followed at the non-drive end. This method of assembly ensures accurate coaxial alignment of the parts and assists in reducing wear on the seals thus extending the life of the equipment. Typically, seals of the lip type are employed.
Patent DE-2620735-A1 (DE)
Inventor: TERADE KIICHI
IPC: G04C13/11
Filed: 1976-05-11
Abstract: In an electronic timepiece motor, a one-piece stator of magnetic material having a hole therethrough bounded by a circumferential sidewall and defining a pair of stator portions connected by narrow bridges having small cross sections. The narrow bridges define a magnetic circuit of high magnetic resistance between the stator portions. A non-magnetic reinforcing ring is disposed within the hole through the one-piece stator and has an outer diameter effective to insure a snug fit of the reinforcing ring with the circumferential sidewall defining the hole through the stator. The reinforcing ring imparts stiffness to the one-piece stator to prevent deformation of the bridges and the hole. The reinforcing ring has a peripheral reinforcing flange extending outwardly and with the flange bearing against the one-piece stator adjacent the hole therethrough for imparting additional stiffness to the one-piece stator. A rotor is mounted for rotation within the hole through the one-piece stator and within the reinforcing ring.

Title: Level warning system for twin fluid reservoir - operates with flexible separating wall and single level indicator
Inventor: QUITMANN HORST
IPC: B60T11/26
Filed: 1976-09-16
Abstract: The two reservoir top up control has a flexible wall (2) separating the two sides, and with one side fitted with a level control gauge (7). The flexibility of the wall is such that when one side is empty then the wall extends into the empty part and causes the remaining fluid leve to settle to the minimum level, to operate the level warning. The system enables the level warning to operate without the loss of any fluid from the intact circuit. Any leakage in one system results in a rapid drop in level, and rapid indication, as no fluid is taken from the other circuit.

Title: Electrochemical machining of recesses inside metal pipe - uses contact rings arranged at intervals about outer pipe surface along length
Inventor: WEHN HEINZ-JUERGEN
IPC: B23H11/00
Filed: 1976-09-18
Abstract: The electrochemical machining technique is used to form recesses in the inner surface of a metal pipe by employing a machining electrode which is moved by a thrust rod through the pipe. Electrical contact rings are placed about the pipe at a uniform separation along its length. The rings are coupled by electric lines to the positive terminal of a direct current source. The electrical resistance of the pipe material between the location of a contact ring and the position at any time of the machining electrode has no influence on the machining operation.

Title: Single phase asynchronous motor electronic control - has HF oscillator synchronized with supply for triac firing
Inventor: REYNA LANDECHO LUIS
IPC: H02P25/04
Filed: 1976-09-23
Abstract: The circuit for speed control of a single-phase asynchronous motor sets the terminal voltage of the motor by adjustment of the firing angle of the traic (8). The shaft of the motor (1) is coupled to a tachogenerator (2) controlling the saw-tooth voltage oscillator (3) which is synchronized with the frequency of the supply network. The oscillator fires the triac (8) through the trigger circuit (4). The output of the tachogenerator (2) is blocked by a comparator (5) as long as the motor speed is below the set limit. At the same time, the -comparator (5) controls the periods of the oscillator (3), and the effect of changes in the supply voltage upon the speed control is eliminated by a detector (10) which corrects the response of the system. The corrective action is facilitated by the adjustable ramp control circuit (6) between the comparator (5) and the oscillator.

Title: Liquefaction of coal - with re-hydrogenation of the donor oil at reactor pressure
Inventor: WUERFEL HELMUT DIPL ING DR ING
IPC: C10G1/04
Filed: 1977-04-28
Abstract: Liquefaction of coal at elevated temp. and pressure, using a hydrogen-donating oil, at least part of which is sepd. in vapour form from the reaction prod. and rehydrogenated with H2 in a fixed bed reactor under the same pressure as the liquefaction reactor. The donor oil is then mixed with fresh coal slurry. The process and equipment are simplified by eliminating pressure release and subsequent re-compression of the donor oil. Separate heating of the H2 used can be avoided by adding it before the liquefaction reactor and/or to the sump of the hot separator where it exerts an additional stripping action of the donor oil vapour.
