Title: Leakage safety unit for hydraulic system - uses parallel pipes with T=pieces to feed pressure side according to pressure sensor
Inventor: SEULEN GERHARD WALTER PROF DR
IPC: F16L55/10
Filed: 1977-07-09
Abstract: The leakage safety unit is esp. for road construction machines or excavators, having a single working cylinder. Parallel hoses or pipes (7, 8), connected at their ends by T-shaped sections (6, 9), supply the pressure side (1, 3) of the hydraulic working cylinder. The T-piece on the feed side is connected to a monitor, consisting of a housing (11) with an internal transmitter (14) and external contact member (15). The monitor reacts to pressure differences in both directions at its connections. A sealing element (5) at the cylinder inlet (3) reacts to the signal transmitted by the contact member when a leakage occurs at one or both conduits. The parallel pipes consist of twin pipes with a common external skin, each having a circular profile with thin dividing wall.

Title: Volume control equipment for foaming liq. esp. beer - has photo-transmitter and photo-receiver ascertaining reflection of absorptive capacity of liq.
Inventor: DEKAN ISTVAN
IPC: G01F23/292
Filed: 1977-10-15
Abstract: The appts. for determining the volume of foaming liquids has a light source and a photosensitive cell as measuring system in the region of the measuring chamber. The measuring system generates different signals depending on the transmitting or reflecting capacity of the foam-liquid mixture. The measuring sensor (11, 12) generates signals proportional to the ratio of foam to clear liquid which load a controller (31). This controller suppresses according to a transmission function parts of the pulses coming from the sensor. This is done in proportion to the fraction of foam.

Patent DE-2815951-A1 (DE)
Title: Foundry moulding machine mfg. sand moulds in boxes - without precompaction by vibrators by using sand shooter and multicylinder ram
Inventor: GROLLA HERBERT ING GRAD
IPC: B22C15/28
Filed: 1978-04-13
Abstract: The machine table carries a pattern plate on which the moulding box is located. The table is then raised by a piston to locate the top edge of the moulding box underneath a hollow filling frame functioning as a sand shooter. On the inner lower edge of frame are tangential slots via which the sand enters the box to create circular motion of the sand. Located inside the hollow frame are several work cylinders, each with a piston driven independently. These pistons form a ram compacting the sand in the box in a uniform manner. The combination of a sand shooter and multi-cylinder ram permits the elimination of noisy vibrators.

Title: Zeolite prodn. with low fluoride content - in calcium fluoride mfr. from hexa:fluorosilicic acid by adding aluminium sulphate during pptn. to give stable silica sol.
Inventor: SEMMLER HANS JOACHIM DR
IPC: C01B39/02
Filed: 1978-06-29
Abstract: Prodn. of zeolites lowin fluoride from SiO2 sol and alkali aluminate involves reacting H2SiF6 in aq. solb. with CaCO3 at 20-100 degrees C in the presence of a mole Al2(SO4)3/mole H2SiF6 (a = 0.01-0.33, pref. 0.05-0.1) so that a pH of 1.0-5.5 is attained. The CaF2 pptw. formed is filtered off, then the filtrate, which is a SiO2 sol, is mixed with an alkaline soln. of b mole alkali (na)aliminate ( is not 2a) and kept at 70-100 degrees C. The crystalline (Na) zeolite (esp. zeolite A) formed is sepd. Process makes possible the conversion of SiO2 obtd. in the mfr. of CaF2 from H2SiF6 into zeolite, since a stable fluid SiO2 sol is obtd., rather than a gel which is difficult to process. The process is suitable for batch or continuous operation.
Patent DE-2829217-A1 (DE)
Title: In=line pipe connection for container top - has sliding fit with pipe to accommodate gap between latter and mating connector
Inventor: GOTTFRIED JOSEF ING GRAD
IPC: F16L27/12
Filed: 1978-07-03
Abstract: The pipe connection (1) is used to make an in-line joint between a pipe which is a sliding fit in the former's internal dia. (3) and a threaded connector which screws into the internal threads (4). The other end of the connection is sealed by screwing the union (10) over the external threads (6), compressing the O-ring (9) on to the outside of the pipe. This allows the pipe to be cut to only the approximate length, since it is possible to leave a gap between it and the connector which mates with the internal threads.

Title: Hot air welding gun control - by air temp responsive PTC resistor controlling triac for heating element
Inventor: BALTUS RENE
IPC: B29C65/00
Filed: 1978-10-20
Abstract: A hot air welding gun for use in welding thermoplastic articles is equipped with a triac in the supply circuit of the heating element spiral, and with a potentiometer for manual setting. The firing of the triac is controlled by a resistor with a positive temp. coefft. which responds to temp. rise and increases its resistance when the temp. should rise because of a reduction in the rate of the cold air supply. The changed resistance acts on a integrated circuit on a printed circuit board and reduces the firing pulses for the triac. This keeps the heating element spiral at the lowest temp., compatible with the air supply rate, and results in a longer life of the heating element. Damage due to fusion of the ceramic element holder at temp. exceeding 1000 degrees C is reliably eliminated.

Title: Radio receiver with digital frequency display - sets frequency by entering desired frequencies into reference memory producing difference to adjust VCO
Inventor: KOHLBACHER GERHARD DIPL ING
IPC: H03J5/02
Filed: 1979-03-22
Abstract: The radio receiver has the count of a crystal-controlled frequency counter compared with a stored reference count and the resulting difference used to adjust the frequency of a v.c.o via and a-d converter. The counter's contents are entered in the reference memory when the frequency setting device is triggered by a sensor. Either the entire contents of the counter are transferred or only those places needed for fine adjustment of the oscillator's frequency. A given number of frequencies may be stored in an extra memory for transferring to the reference memory when a frequency selection key associated with any one of these frequencies is operated.
Patent DE-2913684-A1 (DE)
Inventor: STERN SALOMON
IPC: F16H19/00
Filed: 1979-04-05
Abstract: The device has a drive mechanism and a conversion device, which are connected to one another via tension cables (71, 72, 73, 74) arranged in pairs. The drive mechanism consists of a driven, one- or multi-part balance beam (5) which swings backwards and forwards or of a roller which rotates backwards and forwards, to which the tension cables are attached in such a way that, during each swinging movement, one tension cable of each pair performs a pulling movement and the other tension cable performs a relief movement. The tension cables are each attached to the free end of a pawl (61, 62, 63, 64) of the conversion device, which pawl is seated via a ratchet on the rotary shaft (3). The ratchet is such that, when the pawl moves in one direction, it takes the rotary shaft along and, in the other direction, returns in idle mode. Seated fixedly on the rotary shaft is a roller onto which the tension cable (40) of the load (44) winds. The stroke force can be increased in relation to the driving force by appropriate choice of the lever lengths. <IMAGE>
