Title: Wooden component nail plate connector - comprises projecting nails with heads flush in metal plate and intervening spaces filled with adhesive
Inventor: BRUNOTTE REINHOLD DIPL ING
IPC: F16B11/00
Filed: 1976-02-19
Abstract: The nail plate is used for joining wooden building components together. It incorporates a retainer plate with nails projecting at right angles. There are nails (7-9) with their heads (4-6) lying flush on a metal plate (2, 3) and fixed to it, and pref. passing through it. They may be firmly fixed in apertures, smaller than their cross-section, with simultaneous outward curving of the apertures. They may be fixed with a metal adhesive. The nail heads can be mounted between a layering of two plates (2, 3) with the intervening spaces filled with adhesive (13).

Title: Cleaning gap-filter candles in situ under pressure - to remove internal deposits of kieselguhr etc., e.g. in filtration of beer etc.
Inventor: OLBRICH REINER
IPC: B01D29/46
Filed: 1976-02-20
Abstract: Process is carried out in a filtration vessel. The liq. filters through the gaps between rings placed one on top of the other. The residue, of turbidity-forming materials and e.g. kieselguhr, is deposited on the outside of the filter candles, whilst the filtrate leaves via the cylindrical interval spaces in the filter candles. The filter vessel is filled with water which is then removed continuously from above the filter candles and recirculated by a pump to a point below the filter candles. Compressed air is introduced with the recirculated water, and leaves the upper part of the vessel at atmos. press. The press. fluctuations break up and permit the flushing out of deposits of kiesel gur formed inside the filter candles.

Title: Phase controlled transmission aerial array - has selectively switched single primary radiator feeding first and second radiation elements and HF changeover switch
Inventor: KNOPF ALOIS DIPL ING DR
IPC: H01Q25/00
Filed: 1976-03-20
Abstract: A phase controlled transmission aerial array has energy supplied via a primary feed system. The feed consists of a number of radiation elements arranged in rows and columns. The signals are converted into a primary wave electronically. The desired deflection of the beam is via a phase shift network. There is a secondary array of radiator elements also arranged in rows and columns. In the receiving mode the direction of the energy is in the opposite direction to the first array. There is a single primary supply system which feeds either the first or the second set of radiation elements. The feed is conventional through the free space using a primary radiator (P) or a high frequency cable. The direction of maximum radiation of the aerial array can be selectively switched between the first and second radiator elements. The phase shift network can be controlled via a high frequency changeover switch.

Title: IC engine with variable inlet valve timing - has spring loaded inlet valve controlled by dual disc cam giving variable moment of closure
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: F01L1/30
Filed: 1976-05-14
Abstract: The load regulation system is for an IC engine running on fuel mixture and having an inlet valve (11). Regulation is achieved by varying the charge admitted to the cylinder as a function of engine loading by bringing forward the moment of closing to effect a reduction from full-load charge. The valve is spring-loaded (13) to open and is closed by a cam (10) whose opening and closing profiles (19; 21, 21') are rotatable relative to one another, and whose opening profile (19) may be shortened by rotating the closing profile (21') in the direction of cam rotation. The cam may consists of two co-axial cam discs (10a, 10b) which are rotatable relative to one another and have equal basic circle diameters corresponding with the closed position of the valve.

Title: Rotating spindle of shut-off valve - is actuated by cylinder assembly with rocking piston rod motion
Inventor: ROPER DANIEL GUNDER
IPC: F16K31/163
Filed: 1976-07-13
Abstract: A shut-off valve (14) which is operated by a rotating spindle (54) has the spindle arm (52) attached to the piston rod (30) of an actuating cylinder (16). The piston (28) which is of short axial length has spherical diameter (40) with a location groove for an O-ring (38). Since the piston rod and piston produce a small angular movement during the valve operating stroke, the seal plate for the piston rod (30) is able to slide radially in its location. The arc described by the spindle arm (52) does not impair the cylinder function.
Patent DE-2631596-A1 (DE)
Title: Water cooled heat exchanger for closed circuit wind tunnels - has grid of square air tubes and vertical coolant channels
Inventor: STUTZ HANS
IPC: G01M9/04
Filed: 1976-07-14
Abstract: The water-cooled heat exchanger for closed-circuit wind tunnels causes little pressure-loss and can take over the function of the usual grid to produce a laminar airflow. The cooler comprises a grid of vertical channels through which the cooling medium, e.g. water is made to flow. The medium is piped from a recirculating system external to the wind tunnel and enters the cooler at the top (2). Between the vertical columns are rows of square tubes (4) open at both ends and aligned with the axis of flow within the wind tunnel. The warm air flowing through the tubes loses heat through the thin tube walls to the medium circulating in the vertical channels. The coolant flows out of the exchanger through an outlet at the base (5).

Patent DE-2638202-A1 (DE)
Title: Plastics welding template, esp. for window frame corners - comprising a mould fitting onto frame members to prevent flash forming at weld
Inventor: URBAN JOSEF
IPC: B29C65/20
Filed: 1976-08-25
Abstract: The template comprises upper and lower plates parallel to the plane of the window frame or members to be welded together. The clear space between these upper and lower plates is just equal to the depth of the frame members, so that their ends can be introduced between the plates and held in the correct posn. A heated weld plate is then introduced between the facing surfaces of the members, within the depth of the space between the upper and lower plates of the template, and is finally withdrwn so that the members can be brought together and welded a their surfaces. Since the upper and lower plates define a space o depth exactly equal to the depth fo the window frame members, it is not possible for the weld to form an external beading requiring subsequent removal. Instead, smooth edges to the weld are formed by the inner faces of the upper and lower plates of the template.

Title: Radiative heating element for ceramic hob on cooker - has spiral heating filament embedded in radial retaining ribs on plate
Inventor: FISCHER KARL
IPC: F24C15/10
Filed: 1977-07-02
Abstract: The radiative heating element, for a cooker glass ceramic hob, has an insulating plate (20) with raised radial ribs (24, 25) through which the spiral heating filament (21) passes. Between the ribs, the filament rests on the top surface of the plate. During manufacture, the filament is pressed into notches in the ribs. There are two sets of ribs: a longer set extending from the periphery of the plate to its centre region and a shorter set between the longer ribs.

Title: Ionising voltage generator for electric air conditioning - uses main AC voltage fed cascade circuit with ionising voltage half-wave
Inventor: FURCHNER HELMUT
IPC: H01T23/00
Filed: 1977-09-26
Abstract: The ionising voltage generator uses a main supplied cascade circuit, which rectifies the alternating voltage at its input side and provides the voltage amplification up to the required 7 to 11 KV. Since a half-wave voltage appears at the circuit output, smoothing capacitors may be omitted. Preferably needle-shaped electrodes are in parallel at the circuit output. The generator uses a printed circuit board, on which are mounted the cascade circuit capacitors which enclose a sharp angle with the circuit board long axis. If two rows of capacitors are used, diodes are mounted inbetween. At the input side may be provided a potentiometer with a switch.
