Title: Filter for separating blood serum - piston with filter element attached to receiver for the serum
Inventor: SARSTEDT WALTER
IPC: A61B5/15
Filed: 1974-03-30
Abstract: Filter for sepg. blood fractions consists of a cylindrical vessel in which an airtight piston made from a flexible material such as plastic runs. This contains a filter element which is permeable to the blood serum but impermeable to the blood cake. The piston has a narrow neck into which the point of a pipette can be inserted. The pipette has a larger cross-section body and a female compling capable of being connected to a suction source. Alternatively the piston has a cylindrical depression in it which will accept an insert either or both the surfaces of insert and cylinder being roughened and permitting a flow of serum past the insert. In another yarn. the piston can have an extended transparent stem. The method allows the serum sample to be removed from the cake safely and without fear of contamination.

Title: Table tennis training installation with ball collector net - uses leaf spring deflection for throwing ball
IPC: A63B69/40
Filed: 1974-04-24
Abstract: A table tennis training installation has a ball throwing mechanism located at one end of a ping pong-table. A forked leaf spring is clamped horizontally so that the free ends of the two prongs can be deflected downwards by a continuously rotating cam disc. Collector chutes on either side of the throwing mechanism feed tennis balls onto the deflected spring prongs prior to their release. When the spring is released the ball is thrown against an inclined deflector board from where it flies across the net so that it can be returned by the player. A high net which encloses the throwing end helps to collect the balls in the feed chute.

Title: Vehicle brake monitoring circuit - using direction flasher unit to generate periodic warning signals
Inventor: BOCK WILLY
IPC: B60T17/22
Filed: 1975-04-10
Abstract: The vehicle brakes are fitted with a simple alarm switch to operate if one or other of the brake circuits fails.

Title: Inductive heating system for tempering steel tubes - uses heating temperature and wall thickness in formula giving energy requirement
Inventor: NARIHARA KATSUHIKO
IPC: H05B6/02
Filed: 1975-08-16
Abstract: An inductive heating system for steel tubes of various diameters and wall thickness to various temperatures, particularly for tempering the material using an induction furnace, passes the steel tube through an inductive oven coil (2) and the temperature raised locally in the tube by induced eddy currents, typically to six to nine hundred degrees centigrade. Problems arise because the ends of the tube diffuse in temperatures from the heated section by an amount depending on the velocity through the oven, tube dimensions, and surface absorption layer properties. A number of graphs are presented relating these parameters under various temperature conditions and a number of associated formulae used includes one which uses the heating temperature and wall thickness to give the electrical energy required. The tube is heated between 2 and 10 minutes.
