Title: Pneumatic conveyor pressure vessel venting equipment - uses ejector to discharge air and deliver to pressure pipe
Inventor: STAMER WALTER
IPC: B65G53/14
Filed: 1976-06-24
Abstract: The venting equipment is for pressure vessels used in pneumatic conveyor systems, before loading them with material. The vacuum effect in an ejector (7) is used to discharge air from the vessel, and with its effect the air is delivered into the pressure pipe (5) in front of the vessel. The ejector can be mounted between the conveyor jet (6) and the blast pan (4) of the vessel, the jet having a union for the air discharge pipe (8) from the vessel vent valve (9). This union can be situated at the narrowest portion of the ejector. The design ensures that any solids in the vented air are delivered into the conveyor and do not pollute the surroundings.

Title: Permanent connection between formwork and concrete - involves flat pref. metal or plastic element with contact surface permanently force locked
Inventor: SIMONS FRANZ DR ING
IPC: E04B1/16
Filed: 1976-10-26
Abstract: The concreting form unit is designed so that it need not be removed after concreting, but instead remains permanently force-locked to the concrete, so tha further building components can be firmly fixed to it. The flat connecting element, lying against the surface of the concrete component, is pref. of metal or plastic, and has its contact surface firmly joined to the form. Bent pieces projecting sideways into the concrete may be used for anchorage; or it may incorporate fixture pieces, with heads anchored in the concrete. Two adjacent form panels may be joined by the connecting element, their edges being rounded off so that soft concrete does not penetrate into the widened joint gap.

Title: Reciprocating electromagnetic motor - has rotor moving linearly between stator electromagnets and linked to crankshaft
Inventor: KLINSING WILHELM
IPC: H02K53/00
Filed: 1976-11-25
Abstract: The motor consists of a reciprocating electromagnetic rotor driving a crankshaft (4) (which in turn drives a vehicle). The reciprocating rotor winding (3) interacts with two stator windings (1, 2) such that at one end like poles repel and the rotor is driven towards the other end. At the other end the polarity of either the rotor winding or the stator windings is reversed so that the rotor is repelled back again to the first end.

Title: Electrical resistance thermometer circuit - comprises three branch circuit connected to constant current source which corrects for connection lead effects
Inventor: EGGERS HERMANN RAGNAR DIPL ING
IPC: G01K7/20
Filed: 1977-01-12
Abstract: A three branch current circuit containing resistance thermometers for temperature measurement so arranged as to correct for the effects of the connection leads to the thermometers. Two branches each containing an identical resistor are connected together at one end to a constant current source. The voltage drop across the other ends which are connected, are to the thermometer and the other to another resistor is measured. Current in the various branches is controlled from comparison of this voltage drop and the voltage os the constant current source. For temperature difference measurements a thermometer is connected in the two branches. A temperature dependent voltage source is used to ensure linearity of the output voltage for lage temperature ranges. The circuit can be made suitable for measuring temperature in an explosive atmosphere by fitting Zener diodes outside the explosive area.

Title: Zinc recovery from suspensions of zinc cpds. - by electrodeposition onto aluminium cathodes from sulphuric acid-contg. electrolytes
Inventor: UDUPA HANDADY VENKATAKRISHNA
IPC: C25C1/16
Filed: 1977-07-05
Abstract: Zn is recovered by electrolysing a suspension of residual Zn cpds., such as froths and galvanising residues, Zn oxides or hydroxides from the chemical industry and from paints. The Zn is deposited on Al cathodes the anodes being made of a Pb-based alloy. The Zn cpds. are added continuously to the slurry to maintain the concn. of metals. The electrolyte is an aq. soln. of H2SO4 with a concn. of 5-25% an delectrolysis is carried out at a current density of 2.5-20 A/dm2 at 25-60 degrees C and with a Zn concn. in the electrolyte of 20-100 g/l. The Zn may be obtd. as a homogeneous sheet from these residues without dissolving the Zn cpds. separately e.g. by converting them into soluble salts. Thus avoiding filtration of these soln. Impurities e.g. Fe remaining in suspension can be opt. removed by decantation, sedimentation or filtering. Continuous operations can be achieved by adding Zn cpds. at predetermined intervals. The deposit has a high purity (99-99.8%). During melting higher efficiencies are achieved than with Zn deposit from alkaline suspensions. The electrolyte may be re-used several times.

Title: Paint spray masking process - uses strip with adhesive on both sides to stick to work and attach protective cover
Inventor: UEMURO TAKAMICHI
IPC: B05B15/04
Filed: 1977-10-17
Abstract: The paint spray process has clearly defined boundaries between surfaces to be coated. An adhesive strip with alternate front and back adhesive edges has a back adhesive surface which is fastened along the boundary line, its external edge being in contact with it. A protective cover is adhered to the other adhesive surface on the front of the strip, so as not to project over the boundary line. This prevents the accidental spraying of the surfaces not to be coated. Paint is then sprayed onto the surface to be coated, with the protected surfaces also being partly coated. Protective cover and adhesive strip are then removed.

Title: Pressure-sealed gate valve - has stepped seal ring engageable with gate in inlet side and released by changing pressure application region
Inventor: KAMMERER HANS
IPC: F16K3/20
Filed: 1977-10-15

Title: Heat pump with theoretically zero power consumption - where silicone rubber elastic band is stretched in one environment and relaxed in another
Inventor: GENSWEIN GEB SCHMITT ANNEMARIE
IPC: F25B30/00
Filed: 1978-06-28
Abstract: The heat pump has a theoretically nil power external energy consumption in transferring heat from a reservoir at lower temp to one at higher temp. An elastic material, whose specific heat varies with applied force, is used simultaneously as a heat store and heat conductor, it passes slowly and continuously in a circuit through the lower and higher heat reservoirs, it is relaxed when in the lower and stressed in the higher reservoir. It does not convert mechanical work of a compressor into heat i.e. the work done in changing its volume is virtually recovered and it is therefore virtually an ideal machine.
