Title: Control for DC motor in bridge circuit - has digital logic circuits coupled to divider outputs giving zero motor current at zero speed
Inventor: BISKUP KONRAD ING GRAD
IPC: H02P7/03
Filed: 1975-12-24
Abstract: The dc motor function is determined by the mark-space ratio of control pulses. Identical trains of impulses with a 1:1 mark-space ratio at the inputs (a,b) give, together with the output of a summing amplifier (1)(c), either a positive or negative signal across the voltage dividers (2,4;3,5). Digital logic circuits (6,8;10,12) coupled to the divider outputs (d,e) then give signals through one or other of the channels (9,13;7,11) to connect either one pole or the other of the dc supply (f,g) to both ends of the motor (16). No motion results as there is no current flow. If the mark-space ratio departs from 1:1 then the logic channels do not operate simultaneously and complementary bridge transistors (19,20;17,22) turn on controlling the applied voltage and hence both speed and direction of the motor.

Title: Synchronizing quartz oscillator of clock - by determining phase differences used to adjust system
Inventor: HUMMEL HERBERT
IPC: G04C11/08
Filed: 1976-01-22
Abstract: A quartz oscillator of a clock regulating system, in which the frequency of the system is influenced by pulse rates or clock pulses derived from the oscillations of a quartz crystal is scynchronised by taking an effective signal from the oscillating system and determining, by phase comparison with the derived quartz pulses, the frequency deviations of the effective signal. The frequency of the oscillating system is then modified as a function of these frequency deviations.

Title: Sulphuric acid mfr. by two stage concentration - and removal of pptd. metal salts
Inventor: MAUER JOSEF DIPL ING
IPC: C01B17/90
Filed: 1976-04-26
Abstract: Dil. H2SO4 solns. contg. FeSO4 are treated to obtain more conc. H2SO4 and remove the metal salts. The H2SO4 is conc. in two stages to 60-70wt.% H2SO4 by, in the first stage, preconcentrating by indirect heating until 25-32wt.% H2SO4 is obtd. so that no or only unharmful metal salts are removed and then concentrating the preconcentrate. This is achieved by mixing the preconcentrate with hot superconcentrated H2SO4, which has a 90-96wt.% H2SO4 content, so that steam is given off and the metal salts are pptd. The pptd. salts are removed, opt. after cooling, from the conc. H2SO4 which has a 60-70wt.% H2SO4 content and this conc. H2SO4 is superconc. to 90-96 wt.% H2SO4. Sufficient amts. of superconc. H2SO4 are obtd. to be recycled for the concn. of further amts. of preconcentrate.

Title: Engine with eccentric rotor - has two seal strips with compression space connected via valve to give two cycles per revolution
Inventor: FLOERING PAUL
IPC: F02B53/08
Filed: 1976-10-28
Abstract: The rotary piston engine comprises a cylindrical housing (3) containing an eccentric rotor (1) with two diametrically opposed sealing strips (4) and provided with inlet and outlet ports. It contains a separate compression chamber (7), with or without spring-loaded piston, which chamber is connected to the cylinder housing (3) via a controlled valve (6). During the first half revolution the valve (6) connects the compression space in the housing with the chamber (7). The valve then closes and connects the chamber (7) with the expansion space in the housing whilst fuel is admitted and ignition initiated expansion taking place during the second half revolution. The arrangement produces two complete working cycles per revolution.

Title: Engine mixture ratio control - has probe to compare exhaust oxygen output with reference which is varied to stay above lower probe output limit
Inventor: SCHNUERLE HANS
IPC: F02D41/14
Filed: 1976-10-29
Abstract: The engine fuel mixture ratio control is modulated by a probe which determines the composition of the exhaust gas. It comprises a comparator circuit which compares the probe output signal with a threshold voltage and produces an output, indicating rich or lean mixture. This is further processed by the switching elements of the mixture preparation unit. A circuit receives the variable lower limit voltage of the probe and acts on a threshold adjusting circuit associated with the comparator such that the threshold value, which opposes the probe output, remains above the lower limit of the probe voltage. The circuits may be so arranged that the threshold is nut adjusted until the lower limit exceeds a given value.

Title: Body impact reducing seat-belt connection - has cable coiled on torsion-spring loaded spool with ratchet mechanism controlling rotation
Inventor: MOELLER REINHOLD
IPC: B60R22/28
Filed: 1976-11-06
Abstract: The device is used on seat belt connections to reduce the impact of the user's body against the webbing. It has a torsion spring, one end of which is connected with a spool and the other end with a frame structure bolted to the car body. The spool has a coiled-on length of cord connected to a cable to which one end of the seat belt webbing is joined. Following a pull on the cord, the spool is rotated and part of the force is taken up by the torsion spring. The rotary movement of the spool is controlled by a ratchet mechanism allowing the spool to rotate only in the spring tensioning direction. The ratchet mechanism thus prevents a backlash, when the rotary movement stops.

Title: Support for flexible cable supplying trolley on rails - has cable doubling back on itself, being supported on two groups of carriages running on parallel tracks
Inventor: SCHUSTER ALOIS
IPC: H02G11/00

Abstract: The cable supplies a trolley running on a loading bascule bridge. When the trolley moves, the cable moves on a following carriage to which it is attached. The cable carriages run on two tracks parallel to the trolley direction of movement. The cable starts from a fixed point between the hinges of the loading bascule bridge, and runs in a first direction away from the hinge on first group of cable carriages on the first track. The cable doubles back in the other direction on a second group of carriages on the second track, to the trolley.

Title: Warm air hand dryer - incorporates motor with fan electric heater, and sensor, with rotationally symmetrical interior preventing air escape
Inventor: TIEFENAU HELMUT DR
IPC: A47K10/48
Filed: 1976-12-17
Abstract: The warm air hand dryer contains a motor with a fan (1) on the back of the gadget which conveys air round a guide piece (2) to the outer sides. Behind the electric heater (3) is a temp. sensor (4) which regulates the air temp. The air passage is rotationally symmetrical, so that the air is conveyed in a widening section so that there is slight excess pressure (7) at the inlet for the hands. This prevents any air from passing outwards through the inlet. Air is brought in from outside in the under-pressure area (9) near the fan axis pref. through a filter or disinfectant system (13) (14). The air circulation can be increased around the hands by turbulence producer (6).
