Patent DE-3909633-A1 (DE)
Title: Proportioning pump
Inventor: BIRMELIN UWE
IPC: B05B11/00
Filed: 1989-03-23
Abstract: The invention relates to a proportioning pump (metering pump) (1), which, in particular, can be fitted onto bottles (3) or the like, comprising a pump chamber (17) formed by pump bellows (B) and two valves, of which the inlet valve (V1) is located in the bottom region of a barrel (10) which is joined to the pump bellows (B) by a push-fit fitting, encompassing them, and whose inner wall guides a movable pump top section (11) which has a nozzle duct (46) downstream of the outlet valve (V2), is linked to the pump head by push-fit of a stub (29) and, by means of a sleeve wall (31) is seated on an annular shoulder (collar) (32) of the pump bellows, which faces radially outwards. In order to achieve accurate valve operation, while retaining a simple design, the invention proposes that the outlet valve (V2) which is actuated by a restoring spring (34), have an axially movable sealing section (37) which is guided by a sealing surface formed in a horizontal roof (35) of the bellows (B), and that the sealing section have a length which corresponds to a multiple of the axial length of the sealing surface (36). <IMAGE>

Title: Underframe for double-axle railway goods wagons
Inventor: TANDETZKI HANS
IPC: B61F1/02
Filed: 1989-04-06
Abstract: The invention relates to an underframe for double-axle railway goods wagons, in particular for carrier wagons for transporting demountable containers, having a central longitudinal carrier (1) and two lateral longitudinal carriers (2) which are connected to one another by means of transverse carriers (3) and head carriers (4) which each bear two lateral buffers (5). In order to make the unloaded weight of the underframe and its torsional strength such that it is possible to increase the overall length and thus the useful loading length while maintaining the prescribed values for protection against derailing, the central longitudinal carrier (1) is constructed as a box-shaped hollow carrier with torsional strength which decreases from the longitudinal centre of the wagon to the head carriers (4). <IMAGE>
Patent DE-3911470-A1 (DE)
Title: Double-chamber mouthpiece for tobacco products
Inventor: RINGE JOACHIM
IPC: A24D1/04
Filed: 1989-04-08
Abstract: Scenario: A room contains a male smoker and a female non-smoker. The smoker enriches the air in the room with nicotine and condensate. He smokes twice: from the cigarette and from the air in the room. The non-smoker is a passive smoker: she breathes the air in the room. Passive smokers are more prone than smokers to the disorders consequent upon smoking because they have not formed the antibodies created by smoking. Thus it may happen that the passive smoker dies of cancer while the smoker remains healthy. A filter does not provide any assistance against the harmful substances in the air within the room; a filter merely reduces the harmful substances which the smoker absorbs on inhaling. If the air in the room is to contain fewer harmful substances, the only remedy is to use mild tobaccos without a filter. This is because the smoker would prefer not to do without the accustomed flavour. Problem: Mild cigarettes without filter are not purchased (example: Stanford, 1980). Smokers today are not accustomed to untipped cigarettes. Untipped cigarettes cause too many problems, because tobacco strands enter the mouth. Solution to problem: This application aims to promote mild tobacco cigarettes by developing a sufficiently simple and inexpensive mouthpiece solely for said cigarettes, and thus to reduce pollution with harmful substances in enclosed spaces, and also the burden on the smoker. Subject of the patent application: The mouthpiece consists of cellulose or tobacco (possibly leaf ribs) processed like papier maché. It does not filter the smoke, but holds ...

Title: Prepress using heat resistant polymers having high softening points - with coagulation bath to remove solvent before drying
Inventor: HORACEK HEINRICH DR
IPC: C08J5/24
Filed: 1989-04-19
Abstract: Duromer or thermoplastic processable prepregs consisting of 50-80 wt. % of reinforcing material and 20-50 wt. % of heat resistant polymers with softening points, above 120 deg.C prepd. by impregnation using a polymer soln. contg. at least one solvent and one salt which are soluble in the subsequent coagulation bath, polymer coagulation and drying in a drying tunnel or tower. USE/ADVANTAGE - Many duromers and heat resisting thermoplastics have softening points above 120 deg.C but are only soluble in solvents with b.pt. above 100 deg.C. In this application  this results in extended drying times. The use of a coagulation bath in which 50-100 % of the polymer soln.  s olvent is soluble removes much of this solvent before drying and the incorporation of salt accelerates solvent removal. Drying times can be reduced to about 10-50% of the customary period.

Title: Transfer of dough lumps from conveyor to oven - by using continuous belt with series of sensor operated containers to transfer dough from conveyor to moulds
Inventor: BOZINOSKI BORIS
IPC: A21B3/07
Filed: 1989-09-05
Abstract: Equipment for transfer of dough lumps from an initial conveyor belt to a second conveyor belt has a continuously circulating belt on which a specific number of containers are located, sensors for determn. of the position of the appropriate container and a system for controlling the delivery in response to a sensor signal. Transfer of dough from the first conveyor belt to the dough moulds is controlled to ensure that dough delivery has a greater speed than the dough receiving stage. An initial conveyor belt delivers dough lumps to twenty equally spaced containers (4) mounted on a continuous belt (2). Ten containers (4) are located on each side of the belt (2). Below the belt (2) are two support rails (8) which can be swung outward and accept twenty equally spaced moulds (6). The spacing of the containers (4) from each eeh other is typically twice the distance between each mould (6). Twenty sensors (9), ten on each side of the device, are located exactly on the middle axis of each mould (6) and operate in conjunction with indicators (10) on the side of each container. Each sensor (9) is linked to a release mechanism (11) which operates via an air cylinder, in the container opening mechanism. USE/ADVANTAGE - Automatically transfers dough in a pre-programmable way to moulds on a second conveyor belt which passes through an oven. Manual filling of moulds is eliminated.
Patent DE-3930556-A1 (DE)
Inventor: SIEGEL HEINZ ING GRAD
IPC: F15B1/24
Filed: 1989-09-13
Abstract: The reservoir (10) has a cylinder (11) and a separating piston (13) arranged to slide therein. The piston separates a pressure medium storage chamber (15) from a gas chamber (14) in the cylinder (11). The separating piston (13) is sealed against the cylinder (11) by at least two rings (20 and 21) arranged at a distance apart axially on the periphery of the piston. Between the piston rings (20 and 21) is a collection chamber (22) from which opens a drilling (23) in the piston (13). The drilling (23) opens into the gas chamber (14) and can be closed off by a return valve blocking the passage from the gas chamber into the collection chamber (22). When the storage chamber (15) is emptied, pressurised gas and liquid conveyed with it from the gas chamber (14) into the collection chamber (22) are fed back into the gas chamber (14) via the drilling (23) on the opening of the return valve (27) as a result of being allowed to pass through the piston ring (20) on the gas chamber side. This lengthens the useful life of the pressure medium reservoir (10).

IPC: A61B1/12
Filed: 1990-02-09
Abstract: After preliminary rinsing, endoscopes held in a chamber (2) are thermally disinfected by liq. from a boiler (16) when the liq. has been brought to reqd. temp. by a submerged heat exchanger coil (17), through which passes the preliminary rinsing soln. Chemical disinfectant (14,15) may also be supplied via valves. Waste water from the working chamber (2) is converted by a still (34), pref.  at temp. reduced by pressure control, to produce fresh water suitable for initial rinsing.
