Title: Gaseous agitation of radio-active solns - in delay storage tanks
Inventor: KINNER JULIUS
IPC: B65D90/22
Filed: 1971-10-04
Abstract: Agitation of particulate radio-active matter held in soln. in delay storage tanks by means of a stand pipe connected ot a gas filled chamber within a pneumatic or hydraulically actuated piston and membrane operate to produce pressure changes in the stand pipe and cause the tank soln. level to fluctuate. The venturi shaped outlet of the stand pipe is positioned close to a diffuser in the bottom of the tank and induces an agitation which disturbs the particulate matter and promotes its distribution throughout the soln. and inhibits localised formation of concd. active matter.

Title: Twin cylinder rotary i.c. engine ignition system - has two contact breakers timed independently of each other
Inventor: TAKEDA YOSHIAKI
IPC: F02P3/04
Filed: 1973-10-11
Abstract: The engine has two cylinders each of which has two sparking plugs. The positive terminal of the battery is connected to the primaries of two coils. The other end of one coil goes through a contact breaker arm to the battery negative terminal and the other end of the second coil goes through a second contact breaker arm to the battery negative terminal. The two contact breaker arms are driven by separate cams which are on a common shaft but can be displaced circumferentially from each other to give different timings. Each coil serves one sparking plug in each cylinder, so that the two plugs in one cylinder spark at different times.
Patent DE-2354028-A1 (DE)
Title: Removable links for chain couplings - consists of two symmetrical interlocking parts with blind slots
Inventor: BUERSTNER HEINRICH
IPC: F16G15/00
Filed: 1973-10-27
Abstract: The links are for use in connecting together the usual closed oval-ring chain links made of round bar. The two parts of the link are exactly alike and each contains a blind tee-slot at one end and a tee-headed key at the other. By fitting the two parts over the ends of two closed ring links and sliding them together a closed rectangular flat link is obtained. For increased security a cross pin may be fitted. Applications are on high load chains used in mining, dock-yards and ships. Other forms of removable link have tee-slots but these appear in both halves and separate bridge pieces are needed; others are of two pieces hinged together. The simplicity and ease of handling are advantages of the invention.

Patent DE-2362002-A1 (DE)
Title: Small injection mouldings separated from sprue - by revolving drum executing stripping action against end of feed chute
Inventor: HOYER ADOLF
IPC: B07B13/00
Filed: 1973-12-13
Abstract: A sorting device for connecting to the discharge side of an injection moulding machine comprises a revolving drum fitted with projecting grabs, spikes or the like; the drum is supplied from a shute with the injection mouldings and their attached screw and, as it revolves, conveys them through a narrow gap between the end of the shute and the cylindrical face of the drum; this gap is only sufficiently wide to permit the small injection mouldings themselves to pass through, with the result that the bulky sprue material is sheared off. The device is used for removing the sprue from very small multiple injection mouldings effected in a single operation, where the sprue is comparatively large. Removal of the sprue by hand is no longer necessary.

Title: Charge and fluid level indicator for accumulator - has transparent communicating tube with coloured float and optical prisms
Inventor: KITAI YASUO
IPC: G01F23/292
Filed: 1974-02-20
Abstract: Indicator for the state of the charge and the level of the liquid in a lead accumulator, showing whether the battery is overcharged or whether the liquid surface is below the prescribed level. A transparent hollow tube fits into the stopper with its lower end submerged in the battery fluid. The space contains a coloured floater. A pair of optical prisms are held in position at the bottom edge of the tube by ring allowing a continuous path for a light beam from the top through the two prisms by total internal reflection and back out at the top. If the floater should sink to the bottom either due to reduction in the density or of the fluid level then the coloured float will interrupt the path of the light.

Title: Gas purging bridge for sample containers - consists of plate of suitable material sealed at edge having conical holes
Inventor: MUELLER RUDOLF DIPL CHEM DR
IPC: G01N30/91
Filed: 1974-02-26
Abstract: Gas perging bridge for hand or automatic charging esp. for thin film and paper chromatography consists of a cover plate with a min made from a solvent and heat resistant material, pref. transparent, provided with >=1 gas inlet branches. In this are >=1 loading holes or slots formed with conical or countersunk holes. In order to improve the seal the edge has a layer of elastic material on it or is provided with a second spring loaded edge. Inside the bridge gas inlet tubes are provided with jet-like openings for the desired purging which pref. are fixed by screwing in or plugging. The whole can be mounted in an automatic charging device by a spring mounting suspended from pins. Alternatively it can be mounted on pins with spring support. For samples used in thin film or paper chromatography where the samples is either susceptible to variations in atmospheric conditions, or where a controlled evaporation rate of solvent is desirable. In some cases the sample is sensitive to O2 and oxidation occurs in the presence of air. The described device overcomes these problems by allowing charging with a controlled atmosphere and inert gas purge, also allowing controlled evaporation of solvent.

Title: Feeding pulverulent plastics components to plasticisers - compressing mixed components to blocks, converting blocks to pulverulent state and controlling compsn of blocks
Inventor: HOFFMANNS WERNER DIPL ING
IPC: B01F15/02
Filed: 1974-04-03
Abstract: In a method of preparing plastics pulverulent materials for plasticising, a number of components in their metered quantities are continuously supplied to a compression chamber in whic the components are compressed to a parison, which is then converted to a pulverulent state for feeding into the plasticiser and the quantities of the components for the subsequent parison compression are derived by measuring the length of the preceding parison and comparing the length with a preset length and using the differential in association with a computer to control the metering devices of the components. Process permits continuous accurate mixing of plastics compsns.

Title: Valve for brake servo master cylinder - with rotating operating sleeve coupled to piston shaft by slanted slots
Inventor: ALDINGER ULRICH
IPC: B60T13/14
Filed: 1974-06-10
Abstract: The control valves which regulate the amount of servo action in a master brake cylinder usually require large operating forces, which influence the action of the operating piston rod. The invention provides a special sleeve (27) fitted over the piston rod and coupled to the rod by pegs (31) on the rod engaging slanted slots in the sleeve. The sleeve is spring loaded on the piston to hold it in one position. The interaction between the operating rod and the piston twists the sleeve so that it operates on the control valve (18) which is mounted at right angles to the master brake cylinder. A smooth servo control is then obtained.
