Title: Adhesive and sealant useful for glazing car windows, etc. - contains a reactive prepolymer which is liq. at room temp. and a solid component which is liq. at slightly higher temp.
Inventor: PROEBSTER MANFRED DR
IPC: C08G18/12
Filed: 1992-03-28
Abstract: Adhesives and sealants (I) are claimed, contg. (a) reactive prepolymer(s) which is/are liq. at room temp. and (b) other component(s) which is/are solid at room temp., liq. at a slightly higher temp. and at least partly incompatible with (a). Also claimed is a process for the prodn. of (I) by compounding at a temp. above the m.pt. of component (b). USE/ADVANTAGE - Used as structural adhesives for substrates made of glass, metal, plastic, building materials or wood, and for the direct glazing of car windows (claimed). The invention provides an adhesive/sealant which is stiff and stable at room temp. but pumpable and workable at 40-50 deg. C.; the material can therefore be appied as a strip or bead and easily corrected with a spatula etc.. The material then rapidly becomes far more rigid than conventional pumpable 1-component systems, so that assemblies such as glazed widnscreens can be moved almost immediately

Title: Reverse-torque-counteraction system for gear-driven external rotors - transfers lubricant to tooth flanks on engagement and use pressure generated to aid disengagement
Inventor: SCHMIDT EDWIN P
IPC: B64C27/82
Filed: 1993-03-09
Abstract: The system is for use for an engine driving via gears an external rotary body on a freely-movable housing, e.g. in a hand drill, motor vehicle, and particularly a helicopter. To counteract reverse torque, when the tooth of the first gear engages between those of the second, the lubricant on it is transferred by tooth pressure and a passage onto the tooth flanks. The pressure thus generated causes expansion, aiding disengagement of the tooth from the second gear. The intermeshing area can be enclosed on both sides for at least half its height. USE/ADVANTAGE - Simplicity, economy of power, and counteracts reverse torque at source.

Title: Valve-cap wrench for car tyres
Inventor: RADU CONSTANTIN
IPC: B25B27/00
Filed: 1993-04-13
Abstract: The "CONRADU" valve-cap wrench is a tubular wrench used for handling the protective caps of tyre air-pressure valves of car tyres. The use of the "CONRADU" valve-cap wrench in the testing of tyre air pressure of car tyres has the following advantages:   a. the dismounting of the ornamental cover from the tyres thus equipped is dispensed with, leading to a reduction in time of 90% of the time required previously. b. Direct contact of the hands with the outer surface of the protective valve cap is avoided, the cap in most cases being covered with fine dust particles as a result of the action of the brake backplates, as well as other dust parts from the bodywork. This dirt is very difficult to remove from the hands. c. The use of protective gloves, which are inconvenient in the handling of the valve protective cap, is avoided.   The "CONRADU" valve-cap wrench has been designed to enable the handling to be carried out with ease. <IMAGE>

Title: Massaging shower head
Inventor: HAMM MANFRED R DR
IPC: A61H15/00
Filed: 1993-07-12
Abstract: There is described a massaging shower head which can be used, for example, for medical therapeutic treatment of metabolic and vascular disorders and their cosmetic manifestations. Several hollow rollers which are arranged in the shower head, whose interiors contain turbines and whose surfaces are equipped with rounded plastic protrusions, are made to execute rotating movements by mechanical water force. On contact of these surfaces with the skin a massaging effects is produced thereby. The ergonomically designed handle facilitates guidance of the massaging shower head and permits intensification of the massaging effect by manual pressure. Besides the physical effects, it is also possible to utilise thermal effects of the water by variation of the water temperature for intensification of the massage treatment. Thus, the physical and thermal effects of water are thereby combined for the first time to selectively support the physiological effect of the massage in a manner which permits application within the framework of customary body hygiene, especially since the massaging shower head can also be used as shower head due to the specific arrangement of the rollers with protrusions.
