Title: Cable bushing for electrical appliance - has two sets of contacts provided for each cable core and more easily disconnected contacts on current supply side
Inventor: BLUM ALBERT
IPC: H01R13/71
Filed: 1976-04-27
Abstract: The joint assembly is liquid-tight sealed between cable and appliance housing, and a deliberate breaking point for cables is provided when an excessive pull is applied to it. The breaking point can be reconnected. A pair of contact sets is inserted into each cable core. They are connected in series, respond to the cable pull and are opened at different pulling forces. Contacts with lower opening force are on the current supply side in a space liquid-tight sealed to the cable. The sealing is achieved by means of a membrane (22) controlled in position by two compression ion springs (23).

Title: Wood chips crusher with material separator - has housing for vertical feed with opening to produce lateral airflow towards impeller
Inventor: PALLMANN WILHELM
IPC: B02C13/288
Filed: 1976-08-17
Abstract: The crusher which handles cellulose chippings, is provided with a foreign matter separating device which prevents heavier particles from reaching the impeller. The loose cellulose material is fed into the casing (30) of the crushing impeller in vertical direction through feed hopper (1). Inside the hopper several chutelike inclined partitions (11 to 14) counteract a possible clogging-up of the material in the hopper. Underneath the partition (14) the outer skin (55) is fitted with a fluted laterally orientated opening (57) through which a constant airstream is entering the hopper produced by the suction of the impeller. The airstream loosens the material travelling downwards, so that only the specifically light material is carried into the impeller, whereas the heavier particles continue to drop downwards and leave the hopper at the bottom opening (60).

Title: Follower piston for short stroke IC engines - has gudgeon pin with slide path to enable piston to lag behind on induction stroke
Inventor: KURZ KARL
IPC: F02B75/04
Filed: 1976-08-28

Title: Current transformer with delayed action - has additional voltage increasing coil, rectifier, RC element and Zener diodes
Inventor: KRAEFT HEINZ DR ING
IPC: H01F27/40
Filed: 1977-01-08
Abstract: In order to attain selectivity between a main switch and series connected switches a current transformer with an additional coil is used. This increases the voltage in a transformer of normal core side. The transformer contains also an RC element and Zener diodes. The current supplied by the secondary winding attains its final value only after a corresponding delay period. In case of faulty current the RC element is supplied with a time-proportional reduced current via the rectifier. The Zener diodes safeguard the time delay also for heavier current values.

Title: Internal flow reversing header for three pass fire tube boiler - is pre-welded to flame tube whose wall forms part of header sidewall
IPC: F22B7/14
Filed: 1977-06-27
Abstract: The internal flow reversing header for 3-pass fire tube boilers is basically cylindrical (5) with its axis displaced from, par allel to, that of the flame tube (4) which runs the length of the boiler. The header dia. is small enought for 1/4 - 1/3 of its sidewall reasonably to be formed by the flame tube wall, welds (11, 12) connecting the two. The common open end of both is sealed by a castable refractory wall (9) embodying the access door (10). There is a partial vertical tube waterwall (8). The tube plate (7) for the second pass tubes (6) seals the gap between header other end and flame tube. To accommodate a superheater, header depth (t) is increased and the waterwall (8) reoriented axially (13) to increase rigidity, provide the tube support.

Title: Nuclear reactor mechanical and fluid cleaning system - has rotating shaft with cleaning head engaging in inner threads with fluid supply
Inventor: BEISSNER HANS WILHELM
IPC: B08B9/02
Filed: 1977-07-21
Abstract: The cleaning head, fitted with cleaning tools which engage into the inner thread of the article to be cleaned, is fastened to a shaft which is axially displaceable in a housing, has a central pasage and is provided with drive means. This composite unit is (partially) balanced by counter-weights which are connected to the shaft and aligned against the direction of displacement of the latter. The threaded support to be cleaned can be positioned and secured on the housing by suitable means following which gaseous or fluid cleaning agent can be supplied to the cleaning head through the central passage in the shaft. The cleaning tools of the cleanin head can be pressed against the inner thread of the threaded support resting on the housing by thrust means which are axial or axially parallel with the shaft or an abutment connected to it. The automatic vertical movement of the shaft with the cleaning head and tools through the inner thread can be restricted in both directions by limit switches and rotary direction reversal switches. As the shaft rotates the cleaning tools move slowly up and down engaging in the threads so that the supply of fluid produces a thorough cleaning action. System is esp. for nuclear reactor.
