IPC: G10H1/44
Filed: 1975-03-05
Abstract: An electric signal or frequency generating device is provided to produce frequencies corresponding to the tone frequencies of the strings of the instrument to be tuned.

Patent DE-2538919-A1 (DE)
Title: Overvoltage protection for low voltage systems - employs parallel connected voltage dependant resistor and gas discharge tube
Inventor: BOSSHARD WALTER
IPC: H02H9/06
Filed: 1975-09-02
Abstract: The protection element can be applied to low voltage systems having a nominal operating voltage of not more than 1000V. The discharge tube break-over voltage is selected to be at least twice the nominal system voltage, and typically between three and five times that value. The voltage dependant resistor is arranged to have a negative voltage exponent of approximately five. Use of this parallel connection ensures that the resistor limits the normally occurring lower voltage and low energy peaks to value well below the break-over voltage of the tube. Continuous supply availability is thus ensured. A high voltage high energy peak produces sufficient drop across the resistor for the tube to strike. The voltage is clipped and the resistor is protected from damage.
Patent DE-2539299-A1 (DE)
Title: Fastener for holding outlet box in distribution trunking - makes use of hooked projection engaging with channel section
Inventor: BLUME FRANZ
IPC: H02G3/12
Filed: 1975-09-04

The outlet box (17) which can be positioned anywhere in the line of the trunking, is typically made of an elastic synthetic material and has a projection on its base (21). This projection comprises two hook-like elements (19, 20), which engage with the turned over edges (16) of the channel section (15). To lock the box in position a wedge (25) is pushed through the base from inside the box to spread and hold the two hooks apart.

Title: Socket with contact bushes - has bushes broken from mains when unplugged and has torque switch making or breaking contacts by plug pins
Inventor: KUEPPERS WALTER
IPC: H01R13/703
Filed: 1975-09-16
Abstract: A socket has its socket bushes free of current when not in use. It contains a switching element which connects the bushes to the current when the plug pins are engaged in the socket. Each current conducting pair has an individual or a common switching element in the form of a torque switch (2). It is located between the mains terminals (5) and the socket bushes (4). The current carrying conductors will either be linked or broken when the torque switch is actuated. The torque switch can be linked to give an indication when the circuit made by plugging in the pins, or broken when pulling out the plug. The torque switch can be of the push button variety and the knob shaped actuator of the push button switch protrudes through a hole in the socket plate of the socket.

Title: Furniture box unit component assembly system - has twin side presses with tranverse conveyor and removal mechanism
Inventor: PRUST ULRICH
IPC: B27M3/18
Filed: 1975-10-10
Abstract: The system for assembling furniture units comprises two side pieces with a rear wall and top and bottom floor pieces using connector fittings or screws. The furniture components are loosely laid out on a carrier and passed between two presses with vertical sides so that the side pieces are pressed towards each other against the top and bottom floor pieces. Attachment of the rear wall is then carried out, while the unit is pressed together and freely suspended. On release of the press sides the assembled unit is deposited on a transverse conveyor for conveyance to a removal mechanism which takes it over as soon as the conveyor draws level.
Patent DE-2552051-A1 (DE)
Title: Overrun plate applicator for transverse welds on rolled products - with slides for transfer from magazine to cross cradle
Inventor: WENNER KARL ING GRAD
IPC: B23K9/038
Filed: 1975-11-20
Abstract: The overrun plates with a central V-notch are located at both ends of the weld run, and are stacked in a magazine on both sides and are transferred one-by-one to a cradle by a power ram. Other power rams urge the cradle with the retained overrun plates against the strip ends. This saves the manual work of inserting and moving the overrun plates by hand. The welding cycle is speeded up.
Patent DE-2559541-A1 (DE)
Title: Plastic extrusion granulator - with water-cooled launder for transferring the extrusion from the nozzle to the cutter roll
Inventor: HUNKE FRIEDRICH
IPC: B29B9/06
Filed: 1975-01-28
Abstract: A granulator for molten thermoplastic resin discharged from an extrusion nozzle, is provided in known manner with a feed device supplied with cooling water, mounted upstream of a cutting roll, which in turn is directly downstream of a pair of feed rolls. The granulator is modified by providing at least one of these feed rolls with longitudinal i.e axially parallel, grooves to ensure that the extrusion is drawn into the roll knip. Advantageously, a reception launder is provided below the cutting roll and additional cooling water is supplied to this launder in the zone between the cutting roll and the bend of the launder. The cost of the equipment is reduced and the tendency of the extruded plastic to stick to the feed device is virtually eliminated.

Title: Pelletising alumina in appts. with tiltable rotating disc - for use as catalyst carrier or moisture adsorber
Inventor: ATTEBERRY GEORGE C
IPC: C01F7/025
Filed: 1976-01-09
Abstract: Alumina spheres, pref. boehmite are continuously produced by the process comprising the following steps. (A) alumina ground to 1-50 mu particles is fed into a pelletising appts. provided with a tiltable rotating dose; the tilt is 1-75 degrees; the rotation speed is 1-60 rpm so that the alumina particles form a parabolic surface whose peak lies at 1/8 to 3/4 of the disc dia.; and aq. liquid is sprayed onto the alumina spheres to raise their moisture content to 10-60 wt.%; the rotation is continued until the size of alumina particles increases to 50-65 mesh. (B) the resulting seeds are introduced into the original stream of the 1-50 mu alumina particles, whilst the tilt, the rotation speed and the moisture content are kept constant. (C) Alumina spheres which have reached the desired size are continuously removed from the disc, whilst the tilt, the rotation speed and the moisture content are kept constant. (D) The 1-50 mu alumina particles are fed into the pelletising appts. at the rate (by weight) equal to the withdrawal of the finished spheres. The alumina spheres can be impregnated with a catalytically active metal during or after the formation. Catalyst-carrying alumina spheres having high mechanical strength and low ablation are produced in a simple and inexpensive manner. The alumina spheres (without any catalyst) can be used for water absorption from humid gases.

Title: Iron clad accumulator plate filling machine - with common flat piston for paste, nozzles for tubes and two slide valves
Inventor: BOHLE LORENZ ING GRAD
IPC: F04B15/00
Filed: 1976-01-23
Abstract: A machine to fill paste into the ironclad types of positive plates of Pd accumulators includes a flat piston of the same width as the set of tubes surrounding the lead alloy cores. Nozzles which fit over the tube ends are arranged at the discharge end of the flat piston housing. This saves the necessity for a homogenisation of the paste suspension because there is no phase sepn. The volumetric flow rate during the filling operation is not obstructed and the power required for the drive is reduced.

Title: Electronic automatic control for electromagnetic agitators - uses permanent magnet to trigger field plate sensor with flip flop and logic OR:gate
Inventor: KLEIBRINK HORST
IPC: H02K33/10
Filed: 1976-04-07
Abstract: The unit for electronic automatic control of electromagnetic agitators (stirrers) in sealed pressure vessels uses a permanent magnet for switching the working current for the magnet winding, the permanent magnet being fixed to alengthwise movable armature within a pressure tight non-magnetic housing. The permanent magnet triggers a field plate sensor applied externally to the pressure-tight housing, at the upper and lower dead-centres (TDC and BDC) of the armature stroke or throw. The field plate sensor signal is fed via an amplifier to a flip flop and thence via a logic OR-gate to the gate of a thyristor. More specif. a separate multivibrator circuit is used to set the armature stroke frequency, with variation, independent of the main multivibrator's pulse and automatic drive.
