Inventor: BOURQUIN MICHEL
IPC: G04C23/42
Filed: 1978-03-17
Abstract: The electric toaster has a control mechanism for the movable bread holder which operates by means of a resetting spring (9) which has a delay mechanism. This has a blocking switch mechanism whose spring motor consists of the resetting spring (9) of the movable holder. One (6) of the elements of the kinematic chain which connects this spring to the servo wheel of the switch mechanism is in positive engagement with the bread holder. The kinematic chain can contain a control lever (23) whose axis of rotation (22) is connected to the servo wheel and lies on a path which runs through the element (6) connected to the holder. When the holder is drawn along into the operative position given by the resetting spring, the element displaces the lever to which it is hooked so that the motor force of the spring is then connected to the switch mechanism by the element (6) and lever (23).

Title: PAL replay circuit for colour video recorder - uses NTSC signals on video disc with colour sync. pulses produced from frequency corresp. to colour carrier by splitting into components
Inventor: BRAEGAS PETER ING GRAD
IPC: H04N9/79
Filed: 1978-06-08
Abstract: The relay circuit converts NTSC signals on a video disc into PAL signals for reproduction on a t.v. screen. The chroma signal's second sideband produced when mixing the decoded video signal is used to form a second colour line. The frequency of the colour carrier in the second sideband is converted by mixing into the frequency of the colour carrier in the first sideband, which corresponds to the PAL carrier frequency. The PAL colour sync. pulses are produced from a frequency corresp. to one of the colour carriers by splitting the pulses into +45 deg. and -45 deg. components.

Title: Semiconductor switch for static inverters - has transistor in series with thyristor and switch=off circuit comprising second transistor and power source
Inventor: NESTLER JOHANNES DR
IPC: H02M7/515
Filed: 1978-10-17
Abstract: The semiconductor switch consists of a first transistor (2) in series with a thyristor (1). A third transistor (3) in series with a power source (4) is connected across the thyristor. Both transistors and the thyristor have the same conduction direction. The advantage of the switch lies in its needing no special commutating devices, in having a very low control power consumption, in having a simple control circuit, and in having its thyristor adequately protected against overcurrents without needing fuses or short-circuiting devices. The switch is switched on by first turning on the first transistor (2) and then supplying a current to the thyristor's gate. The thyristor is switched off by the second transistor (3) in series with the power source.

Title: multistage cold forging press for bolts - has optional deburring operation controlled by pneumatic cylinder and piston according to bolt type
Inventor: FLAMME WALTER ING GRAD
IPC: B21K1/46
Filed: 1978-12-30
Abstract: The multi-stage cold forging press can forge bolts either with hexagonal or recessed heads. The hexagonal headed bolts have to be de-burred and this is carried out by pushing the bolt (24) through the de-burring die (6) by means of an ejector rod (11). The ejector rod is pushed forwards by admitting compressed air through the port (17) into the cylinder (16) so that it acts on the piston (14) which pushes the ram (10) against the rod (11). When de-burring is not required air is admitted through the port (18) to retain the piston retracted.

Patent DE-2917270-A1 (DE)
Title: Control for drip infusion instrument - has drip rate controlled by adjustable saw tooth generator whose rising current gradually opens pinch valve
Inventor: BRAMM GUENTER DIPL ING
IPC: A61M5/168
Filed: 1979-04-27
Abstract: With this instrument the normally closed valve is opened slowly by the output from a ramp generator, and is closed immediately after the drip by the ramp voltage being reset. A pulse from an adjustable pulse generator (22) triggers a ramp generator (24) whose rising current gradually opens a pinch value (17) which allows a drop to form (11). As it falls it interrupts light from an 1.e.d. (14). The resulting pulse from the receiving photo diode (15) resets the ramp voltage thus closing the pinch valve and preventing the formation of the next drop until the voltage is allowed to ramp up again by the next pulse from the pulse generator (22). If there is no drop formation due to an empty reservoir or a blocked tube, then the voltage is allowed to ramp up further until it triggers some alarm. The drip rate is adjustable between a few drips up to several hundred drips per minute.
Patent DE-2926082-A1 (DE)

Inventor: SCHUELER ULRICH ING GRAD
IPC: H04M1/82
Filed: 1979-09-18
Abstract: The application is to telephone systems employing digital data or speech transmission. The equipment for monitoring the transmission employs a shift register (SRG) which transfers digital words into a memory (DFT) at a rate set by an address input (AE). The memory is connected to a comparator (COP) and an 01Dgate(U1).Thecomparatorreceivesareferenceinputfroma switched signal generator (SSE). The AND-gate gives the word length, the comparator quantifies the signal level. If the incoming signal level is above the reference the telephone circuit remains connected. If below, a second AND-gate (u2) is activated and, via a time delay (STS), a signal generated (STR) to clear the line if the low level persists. Low level is taken as transmission ended.

Title: Starter for low-pressure fluorescent lamp - has PTC resistor connected to bimetal contacts and to extra contact
Inventor: BUSSMANN HUGO
IPC: H05B41/08
Filed: 1979-10-17
Abstract: The starter has an extra electrode (4) connected to one end of a PTC resistor (3). Bimetal contacts (1,2) are connected to the other end of the PTC resistor so that the voltage drop across the PTC resistor produced by this resistor's heating up when starting is taking a long time causes a glow discharge between the extra electrode and the closed bimetal electrode. The latter then remains closed or only opens infrequently. A diode (5) in parallel with a resistor (6) is connected into one of the leads to the electrodes of the bimetal contacts.
