Title: False twist spindle threading - monofil passing through spindle bore to avoid weakening threading apertures
Inventor: BRICHTA FRANZ DIPL ING
IPC: D02G1/06
Filed: 1971-12-10
Abstract: False twist spindle does not have the usual sideways opening threading apertures by the twist locking pin, thus avoiding deformation by high speed rotation centrifugal forces, and is threaded by passing a threading-up monofil three times through the bore, the monofil being of such length that the latter end is still in the bore while the leading end is being threaded through in the opposite direction, the space between the twist pin and the adjacent unbroken inner wall being less than two monofil dia.

Patent DE-2264524-A1 (DE)
Title: Glaze for split tiles - which will withstand very long kiln firing times
Inventor: BADAWI MOHAMED YOSRI
IPC: C03C8/00
Filed: 1972-03-16
Abstract: The glaze can be applied to split tiles which are to be fired in a zig-zag kiln; it is (a) made fro constituents which are insol. in water; (b) it has shrinkage characteristics which correspond exactly with those of the split tile; (c) it has a softening point above the degassing temp. of the split tiles; and (d) its melting range is wider than that usually employed in the past. It has previsouly been regarded as impossible to fire glazed tiles in zig-zag kilns; this glaze makes this operation possible and thus extends the versatility of this type of kiln and others using a long firing cycle and similar conditions.

Patent DE-2324991-A1 (DE)
Title: Masking and electro-tinning printed circuit boards - giving long storage life, by plating solder eyes with tin or tin-lead alloy
Inventor: BLASCHE EMIL
IPC: H05K3/34
Filed: 1973-05-15
Abstract: The process starts using a plastic board coated on one side with Cu and drilled. A mask is applied by the silk-screen process leaving the soldering-eyes free from lacquer, after which the eyes are electroplated with Sn or Sn/Pb, 10-15 mu thick. The first mask is removed and a second mask applied where the protective lacquer covers the Cu which will form the conductor network, and etchant is used to remove the unwanted copper without attacking the tin. The final step consists of using the first mask to print a layer of a lacquer which prevents soldering on all parts of the board except the soldering-eyes. Thus, the soldering eyes are given a thick Sn or Sn/Pb coating so that soldering is easy even after long storage times.
Patent DE-2332798-A1 (DE)
Title: Controlled number readout and display - is from a memory and enables readout process to be monitored
Inventor: KOEPPL RAINER
IPC: H04M1/56
Filed: 1973-06-28
Abstract: The display and request process of numbes from a number memory is slowed down by a signal controlled by an evaluating unit connected to the memory. A request clock slower than the counter circulating clock interrupts the latter and handles the numbers consecutively, and the numbers are then processed and displayed separately. The advantage of the system is that the read-out process in the display unit can be followed because each number read out is illuminated.
Patent DE-2349219-A1 (DE)
Title: Multiple chipboard press heats stack of boards - simultaneously then removes heating underlays for re-use
IPC: B27N3/16
Filed: 1973-10-01
Abstract: The Parent Patent describes a method of making chipboard and/or fibre board in which a number of mats of material are each placed on an underlay and then stacked; the stack is compressed and heated, by heat transmitted through the underlays, only after it has been completed. The Patent of Addn. comprises a plant for carrying out this process, comprising a spreading station comprising several spreading machines, an accelerating conveyor, a branch leading into two diverging conveyors each of which then leads to separate parallel production paths; each of these paths comprises a feed unit consisting of a stacking station, on which the layers are stacked, opt. also a waiting station, and is followed by the plate press; the discharge unit comprises, opt. a further waiting station and a separating station at which suction lifts or similar remove the finished products. From here, a tippler serves a removal conveyor for the finished products and also a return conveyor, leading to the combined return conveyor for the underlays which are to be re-used. The press is lifted with a power supply for the heating underlays, and a feed conveyor is used for feeding the individual layers into the stack. The individual layers are stacked before being heated, thus saving time; the two-path arrangement results in a compact lay-out.

Title: Cooling system for ship's bows tranverse thruster drive - using water flow through thruster with double walled duct to hold coolant
Inventor: ROSSMANN GUENTER
IPC: B63H21/10
Filed: 1973-11-09
Abstract: The duct containing the bows thruster impeller is provided with a double walled heat exchanger which is connected into the coolant circuit for the drive motor of the thruster. The system enables a closed circuit cooling system to be used, without danger of fouling or freezing. Moving in confined waters can result in ice etc. being picked up by the water intakes, with a resulting overheating of the motors. The amount of coolant drawn through the heat exchanger jacket is proportional to the power demands from the thruster and the system is thus self compensating.
Patent DE-2358947-A1 (DE)
Title: Telephone system with device for emergency calls transmission - has free cell connected to local exchange
Inventor: RUPPRICHT OTTO
IPC: H04M11/04

Patent DE-2410633-A1 (DE)
Title: Serial and parallel output analogue digital converter - outputs both frequency and number corresponding to input
Inventor: KIENCKE UWE DIPL ING DR
IPC: H03M1/00
Filed: 1974-03-06
Abstract: A technique for analogue to digital conversion is used in which an input analogue signal is converted to both a representative output number and a frequency. The basic circuit contains a comparator to one input of which the input signal is applied. A frequency to analogue converter feeds the other comparator input and the output feeds a bidirectional converter driven by a clock so that the direction of counting depends on the comparator output. This in turn feeds a digital differential analyser network which outputs a frequency representing the product of the counter number and another subsidiary clock frequency. This in turn feeds the frequency to analogue converter which comprises two FETs, an inverter and a capacitive changing circuit. The counter automatically arrives at a number representing the input signal.
Patent DE-2411458-A1 (DE)
Title: Side seals for gate valves - has rigid pads pressing seals against valve gate

Abstract: The flat sides and also the edges of the gate valve slider are sealed off above the valve opening by means of flat elastomer sealing plates which are pressed against the valve slider by means of rigid pressure pads on which a variable pressure can be exerted by means of screws. The elastomer sealing plates are mounted without play in recesses in the valve housing. Holes are provided in the housing, so that the edges of the sealing plates placed against the edges of the valve plate, lie directly against the edges of the sealing plates located against the flat sides of the valve slider. The sealing plates for the edges lie directly underneath those for the flat sides.

Patent DE-2419564-A1 (DE)
Title: Rotary IC engine piston oil seal - acts radially and axially in groove with inclined base
Inventor: KATO SHINJI
IPC: F01C19/12
Filed: 1974-04-23
Abstract: The piston has a circular groove in its end face which contains a sealing strip pressing against the cylinder end face. The piston is eccentric within the cylinder and the groove is concentric with the eccentric shaft carrying the piston. The sealing strip is made with a hoop stress so as to be radially elastic and has one axial face chamfered and the other rounded. The back of the groove is inclined at a slope to the vertical. The chamfered face of the strip presses against the cylinder wall and seals the piston to the cylinder. The radial elasticity and the inclined groove back, keep the back of the strip tight to the groove back and thus avoid the need for a separate O-ring.
