Patent DE-3919407-A1 (DE)
Inventor: LINHART MANFRED
IPC: F04B49/10
Filed: 1989-06-14
Abstract: When a compressor has raised the pressure of a fluid, it can be switched to either "idle" or "off". "Off" uses less power than "idle", but repeated switching "off" and "on" can cause the compressor motor 17 to overheat. The control 14, 15 therefore senses pressure 11 and temperature 10, and decides whether to switch the compressor to "off" or "idle" on the basis of the temperature of the motor (either present or predicted at the time when it will need next to be switched "on") so that "off" is selected if the motor will not overheat when next switched "on" and "idle" is selected otherwise. A cooling fan 18 may be provided to accelerate cooling of the motor 17.   <IMAGE>

Title: Heating device with catalytic burner - ignited by flame heating working body and by conduction catalytic element to nominal work temp. and catalytic ignition temp.
Inventor: BOTAZZI PHILIPPE
IPC: B23K3/02
Filed: 1989-10-31
Abstract: Heating device incorporating a catalytic burner (7) is ignited by a piezo-electric element (16,14) which produces a flame on the surface of a perforated ring diaphragm (22) set at a distance from the catalytic element (8) in the gas outlet chamber (10a).  The combustion gas from the aerosol can (4) and air is mixed (6) before flowing through conduit (9), element (8) and diaphragm (22).  The heat generated by the flame heats up the zones (10a,10b,10c) of the heating body which in turn heat up the element (8) until it reaches its nominal work temperature and  commences catalytic combustion. The burnt exhaust gases then extinguish the flame in the chamber (10a). USE/ADVANTAGE - For hair setting tongs, soldering irons etc.  The heating device is rapidly heated to its work temperature via the ignition flame and then continued to heated via the more modest caloric output from the subsequently ignited catalytic burner.

Title: Vehicle cooling-air flap control system - opens and closes front flap to admit cooling air to vehicle by using electromagnet controlled by speed pressure or engine temp.
Inventor: SOJA HEINZ DIPL ING
IPC: B60K11/08
Filed: 1989-12-20
Abstract: The system has the cooling-air flap (32) held closed directly by a retaining or fixing force.

ALternatively the force may be produced by an electromagnet controlled by speed and/or engine temp. The magnet or electromagnet has a plastic coating at least over its region of contact. The retaining or fixing force may be produced by a ratchet or by some form of closure. USE/ADVANTAGE - For controlling cooling-air flap on front of vehicle depending on speed pressure and/or engine temp. Simple to build. Flap is only open when cooling air is actually needed; otherwise aerodynamic, low-noise profile is created by closing flap.

Title: Solar system for heating water - consists of two separate transparent plastics bags containing water with heat exchanger between
Inventor: BOETTCHER ALFRED PROF DR
IPC: F24J2/48
Filed: 1991-02-05
Abstract: A solar system for heating water consists of two transparent plastic foil bags, one on top of the other, each containing separate quantities of water. In, or immediately underneath, the bottom bag is an absorbent pad to absorb the rays of the sun, which then transfers the heat arising to the water in the lower bag. A flat heat exchanger lies between the two bags, and the water to be heated flows through it. The heat energy absorbed by the water in the lower bag is transferred either directly to the heat exchanger or partly through the surfaces of the two bags which are in contact to the water in the upper bag. USE/ADVANTAGE - The underside of the bottom bag can be coloured or black plastic to act as absorber, or the water in that bag can be dark coloured for that purpose.

When the cap is unscrewed from the bottle the ring (17) is held in placeby the teeth so that the narrow necks (18) are broken as the cap is unscrewd and the ring (17) is left on the bottle neck. A cap with the ring (17) separated from the body of the cap indicates that the bottle has been opened. USE - screw caps for bottles.
Patent DE-4108797-A1 (DE)
Inventor: HEITMANN UWE
IPC: A24C5/18
Filed: 1991-03-18
Abstract: For simultaneously manufacturing cigarettes from two tobacco strands (58, 59), a common tobacco stream (V, H) is to be formed which is then divided up or halved to form the two tobacco strands. The aim is to distribute the tobacco or the different tobacco proportions in the tobacco stream in so uniform a manner that part streams having substantially identical mixing characteristics are produced. This is achieved in that in each case a portion of the fresh tobacco supplied to each half (V and H) of the tobacco stream and the surplus tobacco ÜV, ÜH (56 and 57) removed from the tobacco strands (58, 59) is re-directed into the respectively other half or into the half of the tobacco stream associated with the respectively other tobacco strand. In this manner, a uniform thorough mixing of the tobacco stream over its whole width is ensured. <IMAGE>

Title: Notch-free snow-deflecting windscreen above share of snowplough - comprising resilient, pref. polyurethane elastomer, in which sheet construction has variable curvature for opt. clearance and no overflow at all snow conditions
Inventor: HIRT MAX
IPC: E01H5/06
Filed: 1991-04-17
Abstract: Wind-deflecting screen attached to the top of a snowplough share. The screen is a sheet of a resilient material, e.g. polyurethane elastomer, forming an upward extension of the ploughshare without an intervening notch, with positioning mechanism(s) to alter the curvature of the screen, pref. at each side of it. USE/ADVANTAGE - Screen to provide efficient collection and discharge of snow by the plough, irrespective of snow condition, depth of snow deposit and speed of clearance, and prevent collected snow overflowing to back of ploughshare. Absence of notch avoids snow sticking and building up in unfavourable conditions. Adjustable curvature of screen permits independence of conditions. Independent positioning mechanisms permit either constant cross-section (uniform curvature) across the width of the screen, or a conical section for side-discharge, esp. at high clearance speed.

Title: Overhead conveyor with articles suspended from hooks - has step-wise drive actuated by oscillating sliders with ratchet teeth
Inventor: KUHLMANN WALTER
IPC: B65G25/08
Filed: 1991-05-17
Abstract: An overhead conveyor has a support rail (28) and the articles being transported are suspended from hooks (19). The hooks rest on sliders (7,8) which have ratchet teeth (7',8') formed along their upper edges. Each slider has a longitudinal slot in which a bush (16) is fitted. The bush is clamped between side plates (9,10) which are secured to the support rail (28) by a bolt (27). The sliders (7,8) are oscillated in the horizontal direction by a crankshaft driven by an electric motor. The drive is so arranged that the sliders move in opposite directions to each other. The vertical face of the ratchet tooth of one slider thus pushes the hook (19) forward as the other slider is retracted. The hook (19) is thus driven with a stepwise motion along the rail (28). USE/ADVANTAGE - Overhead conveyor which can be operated around curves and is more economical.
