Title: S-Alkyl-thio:chloroformate deriv. prepn. in high yield - from phosgene and mercaptan using activated carbon catalyst
Inventor: KLOIMSTEIN ENGELBERT
IPC: C07C/
Filed: 1977-05-13
Abstract: Continuous prepn. of 5-alkyl thiochloroformates comprises reacting equal amts. of phosgene and a 4-12C alkyl mercaptan counter-currently in two stages. The first stage is carried out at 40-50 degrees C using activated carbon >=2 mm grain size. The mercaptan is charged to the first stage such that it is present in excess and that the mixt. leaving the first stage still has some unreacted mercaptan in it. The second stage is carried out at 40-50 degrees C and with the same type catalyst, but, with the phosgene introduced in excess so that the mixt. from the end of the second stage contains free phosgene, but, no unreacted mercaptan. The final prod. is freed of HCl and any unreacted phosgene by heating in a column and injecting an inert gas. The mixt. of inert gas, phosgene, and HCl is recycled to the first stage, and the final prod. recovered. The prod. is obtd. in improved, quantitative, yield without the need for excessive and expensive safety precautions arising from sepg. excess phosgene from the catalyst.

Title: Air conditioning hollow external wall or roof block - has air chambers with air flow against heat exchange current
Inventor: SAUER KLEMENS DIPL ING
IPC: F24J2/04
Filed: 1977-06-06
Abstract: The structure is for ceilings and roofs and facing walls, and esp. for external parts of buildings bounding interiors. It has hollow spaces through which air can flow, counteracting heat exchange for air conditioning. Here air chambers are built in, so that with suction or blowing-through, the air (L) flows against the heat current (W) resulting from temperature differential between interior (1) and exterior, thus reducing the heat flow from outside or from inside to a minimum. The air flowing through may become warmer in the course of its passage. the heated air may be conveyed to the interior, directly or via a heat pump or heat recovery unit. This considerably reduces the natural tendency towards heat equilibrium between interior and exterior.

Title: Ions flux intensifier using humidified warm air - to transfer ions from weak source material to collecting chamber
Inventor: TATENO SHINJITSU
IPC: G21K1/08
Filed: 1977-07-18
Abstract: An ions flux intensifier for radioactive substances comprises a gas compressor with its discharge line connected to a selectively controlled humidifying and heating chamber; air or gas propelled by the compressor through this chamber enters a container in which radioactive substances are stacked in a series of compartments or shelves. The humidified and heated gas or air leaving the container then passes to a collecting vessel. Specifically, the air or gas can be recirculated through a gap and up through a sand bed at the bottom of the layers of substances. On leaving the radioactive substance chamber the air passes through a meandering labyrinth on its way to the collecting chamber. The process enables an ions flux to be amplified or intensified in a relatively economical and safe manner using relatively weak radioactive substances as the source material.

Title: Wind and wave operated power generator - is moved into sheltered water by excessive wave forces acting against spring-loaded mooring cables trained around rollers
Inventor: SCHATTA MARTIN
IPC: F03B13/18
Filed: 1977-10-14
Abstract: A large dish shaped machine frame is held by cables which run over rollers to a spring loaded reel. The upper flanges of the dish support floats. The waves tend to carry the floats and with them the entire machine towards the lee of the land against the cable tension exerted by the reel.

Title: Wind driven electricity generator - has hydraulic pumps driven by wind wheel, in turn driving hydraulic motor driven generators selectively connected according to wind speed
Inventor: LAWSON-TANCRED HENRY
IPC: H02J15/00
Filed: 1977-11-16
Abstract: A wind driven generator having e.g. a 60 ft. dia. wind wheel and generating up to 30 KW, drives four hydraulic gear pumps through step up gearing. A transducer ensures that only one pump is on torque at low speeds, but further pumps are on torque at higher speeds. The pumps one fed from a header tank, and the hydraulic fluid then passes to a piston and cylinder device loaded with a ballast weight. When pressure rises due to increased wheel speed, the piston operate valves are limit switches and a 5KW hydraulic motor is operated to drive an induction generator. For higher wind speeds, the piston rises further and a second hydraulic motor is operated to drive a generator connected to a resistive load for heating. All these devices are operated intermittently as the wind speed varies. At very high speeds, spoilers or flaps on the blades of the wheel can be operated, reducing the efficiency. The first generator can be used to return power to the local mains. The second generator can have a capacity of between 25 and 30 KW.

Title: Automatic stacking of sand-lime bricks before hardening - where stacks contain gaps to permit handling by fork lift trucks
Inventor: MUELLER DIETER DR ING
IPC: B65G57/22
Filed: 1977-12-09
Abstract: During the fully automatic mfr. of the bricks, a press is used to produce rows of brick blanks; and a hoist fitted with clamps is employed to stack the rows on a hardening trolley. While the hoist is transferring the last row (i.e. the top row) of blanks to the trolley, half the clamps are released to permit some blanks to drop out the hoist, so the last row on the stack contains gaps. After hardening the stack, it is turned upside down; and the gaps are used for the ingress of forks on a fork-lift truck, thus facilitating mechanical handling and/or packing of the stacks of bricks. The unwanted bricks are pref. removed via a conveyor belt. Provides simple handling of the finished stacks of bricks.

Title: Insulating system for TV CRT - increases hv isolation of electrodes by causing discharge to melt projections on electrode surface
Inventor: SROWIG REINHARD ING GRAD
IPC: H01J9/44
Filed: 1978-02-23
Abstract: The insulating system increases the isolation of electrodes in order to protect the t.v. c.r.t.'s cathode from damage. Isolation is increased by generating a h.v. discharge between opposing electrodes before the tube is completed. The discharge occurs in air or in an inert atmosphere at normal atmospheric pressure. The discharge is produced before the electron gun is fitted into the glass tube or it may be produced after fitting. The discharge melts projecting parts of the surface of the electrodes thereby making those surfaces smoother.
