Title: Locking mechanism for vehicle hinged side walls - has lever actuating cam for spring loaded locking rod
Inventor: HILDEBRAND KARL
IPC: E05D15/50
Filed: 1975-06-18
Abstract: The upper locking mechanism is for hinged side walls of a haulage vehicle. The side walls can be hinged about their lower or upper edges. The actuating lever is rotated in the longitudinal direction and outside the hinged walls. This blocking mechanism is universally applicable and prevents accidents, and it is readily operated. The actuating adjustable lever (39) has at one end a cam held in a housing. This cam actuates a spring-loaded sliding rod. The sliding rod is connected to a sliding locking element which slides in a guide (14). This locking element has an upper projection and the locking rod engages with the guide whose upper part is used as a second lock (14) for gripping the locking pin in locked position.

Title: Magneto high tension ignition system - has generator lamination distanced at least 10mm from armature for simple setting of timing
Inventor: WILLER ARMIN
IPC: F02P1/08
Filed: 1975-06-20
Abstract: The rotating permanent magnetic wheel (13) induces an ac into the generator winding (11). The negative half waves are blocked by the two diodes (15) and the positive half waves charge the capacitor (16). The inductive impulse transmitter regulator winding (22) is inductively coupled to the iron core (12) of the generator to produce a number of low negative impulses which are blocked by the regulator diodes (24) but allow the positive impulse to discharge the ignition capacitors (16) via the thyristors (17, 17a). The ignition timing is progressively advanced relatively to increased engine speed by fixing the regulatore core to a conductor plate, which also carries the generator core (12), to give an air gap between the regulator core laminations and generator core of 12mm. The air gap between the regulator pole shoe and the rotating pole shoe is 0.8 mm plug or minus 10%.

Title: Weatherproof prefabricated column supported concrete road or runway - has space below surface for drying and thawing heating system
Inventor: SCHLEDT ALFONS
IPC: E01C1/00
Filed: 1976-02-03
Abstract: System of motorway, or runway track construction, the road surfaces (1) and support columns (2) are built in as prefab. concrete units, in one piece, separated, or erected on site by means of forwarding frame forms, onto the site prepared bases (3) or posts (4).

Title: Position control regulator using parallel connected amplifiers - has triangular waveform signal injected into amplifier control loop in addition to square pulse outputs
IPC: G05B11/28
Filed: 1976-03-08
Abstract: The controller comprises a pre-amplifier (10), coupled with a differential amplifier (14) which also receives input from a reference voltage source (16). The differential amplifier output controls two control amplifiers (20) with different gains, typically 104 and 102, and connected in parallel. Outputs continue to a pair of adder and pulse former units (24, 26) which also receive input from a triangular pulse generator (29). The square pulse outputs from the pulse formers proceed to an operating display device and to a phase controller (36), which, though parallel connected pre-amplifier (40a, b) and driver circuits (42a, b) regulate the position starting motor (M). Phase control is set by an input transformer (38).
Patent DE-2615313-A1 (DE)
Title: Sliding clasp fastener clasp whose cross piece is made pointed - to simplify the fitting of the clasp to the fastener
IPC: A44B19/26
Filed: 1976-04-08
Abstract: The clasp is traditionally fitted on to the closed fastener by opening a gap, then passing the clasp cross piece through the gap, and rivetting it to the back plate. For a more automatic fixing a clasp with a pointed cross piece is claimed. This makes its own gap when pressed against the closed fastener. The point is then fitted into a hole in the back plate of the clasp, and either burred over into a rivet head or fastened by welding.
Patent DE-2616634-A1 (DE)
Title: Oscillator frequency locking unit - uses logic circuit control via fine tuning network to lock on counter frequencies
Inventor: ESPRESTER RALF DIPL ING
IPC: H03L7/181
Filed: 1976-04-15
Abstract: Frequency counter frequencies are spaced by the value of a lowest decade. The two last divider stages (41, 42) of a preliminary divider (41-44) in the frequency counter (31-36) are in the form of binary dividers. Division stages (41-44) are tripped to their other logic stage by one edge of their input pulses, and the frequency counter division stages (31-36), whose contents are displayed in a display device (21-26), are tripped by the other pulse edge. The oscillator (9) frequency is controlled by a logic circuit (61-74 or 102) evaluating output signals of the two last stages (41-42). It controls a fine control part (8) so that the oscillator frequency can be readjusted up or down. Output signal of the last division stage (41) determines the sense of the fine adjustment, and output signals of other stages (42-44) determine the magnitude and frequency from which the fine adjustment is carried out.

Title: Electronic circuit to close slow running jet at over-run - has schmitt trigger with hysteresis ratio to partly restore fuel at predetermined low engine speed
Inventor: LETTENMEYER WERNER DIPL ING
IPC: F02M3/045
Filed: 1976-06-16
Abstract: The slow running switch off valve at closed throttle above a certain defined speed, (1800 r.p.m), closes the slow running fuel jet. Independently from the throttle valve position below a second defined speed (1300 r.p.m) the fuel feed is reintrod- at approximately 50 per cent of the normal feed rate. The slow running switch off valve is connected to an NAND gate whose first input receives a signal only when speed increases above the higher limit and decreases as far as the lower limit. The second input is connected to the ignition contact breakers via a schmitt trigger circuit, with hysteresis ratio.
Patent DE-2639411-A1 (DE)
Title: Telephone exchange system with multistage switching panels - has second connecting lines used for short connections, with contacts of relay inserted into them
Inventor: HOFSTETTER HELGA
IPC: H04Q3/00
Filed: 1976-09-01
Abstract: Switching panel stages consist of switching multiples with first intermediate lines running from one stage to another in reverse grouping. Outputs of two switching multiples esp. in the last stage, are interconnected by second intermediate lines. Connections between two switching panel inputs are made by two part connections which run either through normal paths twice through switching multiples of all stages and one of the above second intermediate lines, or through short paths to a switching multiple at the reversing point of a short path in one of the stages, in which they are combined into one through connection by connection of two switching multiple inputs to the same multiple output. Contacts of intermediate line relays are inserted into the second intermediate lines by which one of the intermediate lines can be broken. When a short connection is made, the second intermediate line connected to the multiple output is broken by operation of its relay to which the two part connections are connected in the multiple at the short path reversing point.

IPC: C09J123/16
Filed: 1976-10-27
Abstract: Preformed blanks of EPDM or EPM rubber mixts. are bonded with an adhesive soln. by vulcanisation. Before pressing together and vulcanising, the surfaces to be bonded together are brushed over with or immersed in a mixt. of 2 solns. consisting of (1) 10-30 wt. % EPDM in benzine and (2) an organic (hydro)peroxide in 10-30 wt. % petroleum ether. Wt. ratio EPDM : (hydro)peroxide in solns. is 3:1 to 7:1.
