Title: Epoxy resin, hardener and mineral filler mixt. - used as waterproofing sealing compsn. for cementing structural joints
IPC: E04B1/68
Filed: 1975-09-02
Abstract: Sealing compsn. for luting structural joints consists of a mixt. contg. 47.5-49.8 pts. wt. epoxy resin, 47.5-49. 8 pts wt. hardener, 0.4-5 pts. wt. mineral filler, e.g., finely-ground asbestos. Pref. epoxy resin is prepd. from bisphenol A and epichlorohydrin and has epoxide equiv. 185. Hardeners may be pre-reacted polyamines with polybutadiene and chlorosulphonated ethylenes. Compsn. is used partic. for cementing structural parts exposed to soil moisture or to underground water, esp. under pressure and stress, e.g. steel, cast iron or concrete tubings and other standard constructional elements used in tunnels and mine-shafts.

Title: Arc quenching switch for overhead conductor rail - has contacts operated electromagnetically by arc current and held closed by time delay
Inventor: LATTEYER GERT
IPC: B60M1/18
Filed: 1975-11-03
Abstract: The adjacent sections of the overhead conductor rail are separated by an insulator which is bridged by a profiled bridge section. As the pantograph wiper passes the insulated point the arc current operates an electro-magnetic switch in the upper insularot, to short the two track sections together and quench the arc. The bottom insular has two sets of contacts separated by an insulating layer. This acts as a capacitor, with the arc striking one plate. The electromagnetic switch operates as soon as the arc strikeS. A mechanical time delay holds th switch in contact for a set time period to allow the train to pass the point.

Title: Baled bagasse prodn. - with disintegration by hammer mill and sepn. of particles into different-sized fractions after initial external treatments e.g. sieving
Inventor: RUCKSTUHL KONRAD
IPC: C13B5/00
Filed: 1975-12-01
Abstract: Baled bagasse is prepared for manufacturing purposes on a prodn. line in which the final disintegration by hammer mill, and the sepn. of the fibre particles into fractions of different size, takes place after a series of disintegration stages outside the mill, by sieving and winnowing, etc. The whole operation is simplified and fewer machines are necessary. The cost of regulating the system is reduced and the output of the mills in particular is increased. The main disadvantage of known systems that in the pith removing and disintegrating machine the bagasse is beaten against the screens which hold back all the fibres whether fine, medium or coarse is overcome. The plant can be supervised by one man.

Title: Hydro-mechanical transmission for vehicle drive - slave cylinders supplied from upstream of throttle valve serving torque converter
Inventor: AAHLEN KARL GUSTAV
IPC: F28D9/00
Filed: 1975-02-11
Abstract: A control system is for a hydro-mechanical transmission for a vehicle drive with a torque converter through which fluid is pumped, followed by one or more epicyclic gear trains with hydraulically-operated friction brakes and/or clutches to provide the different ratios and/or a reverse gear. The fluid for the slave cylinders actuating the brakes and clutches (12, 14)is tapped off from the pressure side of the pump (20) upstream of a throttle valve (145) which can be cut in and out of use. When this valve is in use, the fluid pressure supplied to the cylinders is higher than that in the chamber of the torque converter (22).

Title: Train braking characteristics monitoring system - is used with inductive control system with small number of track magnets
Inventor: UEBEL HELMUT DIPL ING
IPC: B61L25/02
Filed: 1976-04-13
Abstract: An arrangement for pointwise monitoring of brake characteristics of tracked vehicles with inductive control systems is designed to reduce the number of track magnets and to replace the switching units installed along the track by a central weather protected switching installation. One track magnet per monitor point is used. All magnets are controlled from the central unit and each may operate as a vehicle detector and a control magnet. A relay (A) controlled from the central unit via its inputs (SL) opens a contact (a) for detection mode and closes it for control mode. A passing vehicle induces a voltage in the coil (L) which is passed to the central unit via a rectifier (GL) and measurement connections (ML).

Title: Positive release load lifting magnet - has flux short-circuiting links bearing against permanent magnet end faces
Inventor: SCHWARZ WILHELM DR ING
IPC: B66C1/04
Filed: 1976-11-12
Abstract: The load lifting magnet has one or more groups each of two permanent magnets and two common pole shoe units. When switched on, these form unlike poles. And the polarity of one of the permanent magnets is reversed by a current impulse through a partly enclosing coil so as largely to cancel out the magnetic effect and release the load. Each pole shoe unit comprises a magnetic flux short-circuiting link (3, 4) bearing against the end faces of the permanent magnets (i) in each group, and a pole shoe (5, 6) bearing against this link. The link can be formed by two similar flat parallel plates, connected together magnetically by the permanent magnets. The magnetic conductivity of the links is greater than that of the shoes.
