Title: Scoop heat exchanger - rotation of heat exchanger reverses cooling medium flow for brush cleaning operation
IPC: F28G1/12
Filed: 1971-06-04
Abstract: A sea water cooled heat exchangers, requiring frequent cleaning of the cooled surfaces, from deposits, can be rotated by means of a mechanical drive unit to reverse the flow of the cooling medium.

Patent DE-2303788-A1 (DE)
Title: Flow distributor for heat exchanger head - producing uniform flow
Inventor: CATES ROBERT EUGENE
IPC: F28F9/22

Title: Intruder alarm circuit for room skylight - has battery driven alarm device located adjacent peripheral edge of skylight frame
Inventor: ESSER KLAUS
IPC: G08B13/08
Filed: 1973-09-25
Abstract: The acoustic alarm device is secured below the skylight, to the inner wall of the skylight casement. Between the skylight and the casement, a magnet is located, secured to the peripheral frame of the skylight, along one of the edges which moves away from the casement, when the skylight is opened. This magnet controls a release circuit for the alarm device so that when the skylight is opened the alarm is set off and when the skylight is again secured in the closed position the alarm is cut off.

Title: Hot-rolled seamless metal tubes mfr. - esp. of copper and copper alloys, using water or gas to prevent oxidn
Inventor: UHLMANN OTTO
IPC: B21B45/02
Filed: 1973-11-15
Abstract: A mandrel and two or three offset rolls are used to pierce and roll a red-hot blank into tube, the novelty being that directly behind the roll gap the tube is fed into a non-oxidising atmos. The atmos. pref. consists of water or a protective gas, e.g. nitrogen fed through a sleeve placed over the mandrel rod in counter-flow to the tube, and the sleeve can be located in a tank contg. the water or a gas. The sleeve is reduced in section at the mandrel head so it projects right into the roll gap and it may also be fitted with a ring jet e.g. for spraying water onto the tube as it leaves the roll-gap. Water is esp. suitable for use in mfg. tubes in Cu or Cu alloys, while for other materials nitrogen can be used. Tubes can be made with an oxide-free surface, thus eliminating the need for pickling.

Title: Brewery wort copper or mash tub - heated by tube boiler
Inventor: LAMBECK ROLF
IPC: C12C13/02
Filed: 1974-02-16
Abstract: The boiler is arranged in a round basin, or oblong trough attached to the base of the kettle, at a certain distance from the wall and from the base of the basin. A hollow cylinder surmounts the boiler and channels the wort which rises on boiling, the liq. spouts up in the centre and re-descends near the walls of the kettle. In the case of the mash tub, the hollow cylinder has internal grooves and an agitator shaft is provided with blades above and below the boiler. The position of the latter inside the basin allows heating to be started immediately with the minimum quantity of liq. and without the risk of the formation of caramel. Once the b. temp. is reached, a fountain effect is produced above the level of the liq. Stainless steel can be used for the boiler tubes; excellent heat transmission is obtd. with a high rate of evapn. Cleaning can be effected without difficulty by using only a small amt. of detergent in water and completing a boiling cycle.
