Title: PTC resistor and bimetal switch combination - holds button-shaped switch between large area and narrow leads
Inventor: WILMES GERT ING GRAD
IPC: H01H61/013
Filed: 1979-02-28
Abstract: The size of a timer is reduced by a combination of a button shaped bimetal switch and a p.t.c. resistor (6). The holes in the base (I) carry the contacts (2), 3) for the resistor (6) which alters its resistance abruptly above the Curie point. The large area lead is connected to the bimetal switch and is extended into one contact while the large lead bears against the wide lead (9). The location of the bimetal switch provides a good heat transfer path to lead (9) and to the narrow lead. This secures accurate positioning of the components in the assembly.

Title: Decorative concrete facing - applied by temporary fixing a panel on inside of shuttering by nailed PVC foil
Inventor: MACK PETER
IPC: E04F13/08
Filed: 1979-06-29
Abstract: Concrete which is to be used for the facade of buildings can receive a decorative lining of Al or other metal sheeting or of plastic boards. This can be done in one operation when the concrete is poured in shuttering if the aluminium panels, e.g., are bent over on all sides at an angle of 70 deg. A foil of plastic pref. PVC, is bonded to the face to stand out a few inches on all sides. The panel is then fixed to the inside of the tiber shuttering by tacks driven into the plastic foil surrounding the panel. After the concrete has been poured, the foil is removed with the shuttering. This is a much simpler method than mounting on a steel section framework and wooden laths.

Title: Guidance control for inductively controlled vehicles - uses conductor loops to assist or oppose inductive field at branch points
Inventor: DJAMSHIDPOUR MASSOUD DIPL ING
IPC: G05D1/02
Filed: 1979-09-11
Abstract: The guidance system relates to inductively controlled vehicles which are not running on rails is achieved by installing loops of conductors which run along the straight path and the branching path respectively. The direction of the current in these loops is switched by a control such as to assist or oppose the inductive field of the other conductors depending on whether the vehicle is intended to branch off or continue straight. The advantage of this system is that no section is disconnected. The conductor (1) branches after a point (w) into straight conductor (1a) and branch (1b). Both continue to a control station (6) where they are linked to a loop (8) or (9) depending on whether the vehicle is to branch or not.

Title: Pneumatic ventilation grid operating piston and cylinder - has grooves on piston rod engaged by locking member to establish operating positions
Inventor: KRAUS JOSEF
IPC: E05F15/50
Filed: 1979-12-22
Abstract: The pneumatic piston and cylinder for opening and closing ventilation flaps or grids in industrial premises, has its piston (9) mounted on a piston rod (10) with grooves (15,16) spaced apart along it. These grooves correspond with various positions at which the flap is to be set. Two grooves can correspond to the fully open and fully closed positions. The spindle is locked in these positions by locating balls (19,20) incorporated in the end cap (11) of the cylinder (1). The balls are housed in radial holes in the cap, each with a spring (21,22) behind it, and locked by a screw (23,24). Operation is assisted by a spring (14) around the piston rod, inside the cylinder. Another design uses four grooves and a resilient ring supported inside a bellows around the protruding end of the piston rod located inside the grooves.

Title: Mixing added solids in liq. by jets - directed from supports for container sack during cutting open
Inventor: SISTIG KURT
IPC: B28C7/06
Filed: 1980-01-22
Abstract: A sack of solid material for mixing into liq. is laid across two inclined supports with a central gap in a tank for the liq. and is transversely slit above the gap on the side of the sack facing the liq. The material falling into the tank is subjected to multiple pressurised liq. jets which produce a suspension pumped out of the tank. The sack supports consist of two facing and downwardly inclined rows of pipes for supplying the jets, with the pipes in each row offset from these in the facing row. Discharge of the liq. jets is started automatically by the weight of the loaded sack. For smaller sacks a rubber or plastic mask is used. Esp. for mixing kieselguhr with water to form a filter aid in bear production. Agglomerated lumps of solid are not formed, and no dust is evolved. No mechanical stirrers, subject to heavy wear, are needed.

Title: Measuring time between extreme values of varying signal - by counting pulses of fixed repetition rate and having suppression system for noise signals
Inventor: PRAUSE REINHARD ING GRAD
IPC: G04F10/04
Filed: 1980-03-04
Abstract: A method of measuring the time interval between extreme values of a time varying electrical signal voltage is esp. applicable to ultrasonic material and specimen testing. It involves using a transition time delayed auxiliary electrical signal and for little additional equipment cost enables signals of any shape to be dealt with. A gating signal (14) is started by a digital signal (3a) corresp. to the time of a first extreme value (16) of a time varying signal (1) and terminated by a digital signal (3b) corresp. to a second extreme value (11b). The duration of the gating signal is determined by counting a series of pulses from a pulse generator of constant pulse repetition rate. Noise pulse errors can be suppressed using anticipation periods.

Title: Measuring density using float with spring rod supports - having variable clamping for adjustment of measurement range
Inventor: BUSCHMANN HEINZ
IPC: G01N9/12
Filed: 1980-06-24
Abstract: A measurement device, esp. for measuring density, has a moving float whose motion or position is transferred to an indicator. It can be adjusted for different measurement ranges without interchanging or changing parts. Its results are not subject to variations of the guide rod linkages in operation. The float (11) is guided during motion by one or more sprung rods (12,13) which are firmly clamped at its end remote from the float. It may be suspended from two rods. The clamping of the spring rods can be adjusted. This is achieved by varying the position of their mounting (14). The rods, which are held under tension, may be changed for others with different spring characteristics.

Title: Latent heat storage unit - pumps liq. in lower tank into upper tank through heat exchangers for change into crystalline form
Inventor: FREILING HEINZ
IPC: F28D20/02
Filed: 1980-07-31
Abstract: The heat storage device for a heating system uses a substance which changes from a solid crystalline state to a liq. state. Inside an insulated casing is an upper container (2) suspended above a lower container (1). The liq. in the lower container is conveyed upwards by a pump (5) into the upper container where it is changed into its crystalline state. The crystals are warmed by a heat exchanger (3) at the bottom of the upper container, and the liquid thus formed passes through an opening (4) into the lower container. The liq. can then be pumped through a vertical tube (6) to a heat exchanger (7) at the top for discharge in crystal form into the upper container.

Title: Insulated conductor joint - with fusible sleeve between outer sleeve and crimping sleeve
Inventor: EILENTROPP HEINZ
IPC: H02G15/013
Filed: 1980-11-05
Abstract: A joint for electrical conductors is produced by joining their bared ends by a crimping sleeve. A piece of tubing, made of a thermoplastic material of low m.pt., is placed over the sleeve of material with a higher m.pt. and long enough to accept at each end a flanged tubular element. The latter are used to compress the molten thermoplastic material, after heat has been applied by a heating element, wrapped around the external tubing. This eliminated air inclusions and is suitable for areas with a risk of explosions. The joint is easy to accomplish and resists pull, pressure and heat.

Title: Target-seeking missile counteracting enemy defences - uses heat trail of initial missile for course control of subsequent missiles
Inventor: SIEBECKER HANS DIPL ING DR
IPC: F41G7/22
Filed: 1980-12-12
Abstract: The weapon system has a number of parallel firing tubes, which fire their missiles sequentially. The hot-exhaust at the back of the first missile is used as the pilot signal for guidance of the subsequent missiles. The missiles may remain strung out along the same flight path, or they may fan out at the top of the latter, so that they then independently home in on the target. Pref. the initial missile is programme controlled during the first part of its flight path. If the initial missile exhibits an abrupt course deviation, the following missiles are automatically released from its control to allow them to locate the target directly.
