Title: Signal interference suppression cct - is used for interferences superposed on signal containing information and pilot components
Inventor: MINNER WILLY
IPC: H04B1/16
Filed: 1974-05-08
Abstract: The circuit has an interference blocking switch and the signal is applied during an interference absence to a store to a store which stores the signal instantaneous value during the switch response and maintains the pilot signal oscillations the interference free signal at the store output is available for further use. The store consits of a network with at least two parallel branches, one being a series resonant circuit whose resonant frequency is lower than the pilot frequency, the other branch consists of a capacitor, possibly shunted by a second series resonant circuit whose resonant frequency is higher than the pilot frequency, the two parallel network branches have a parallel resonant frequency at least nearly equal to the pilot frequency.

Title: Universal fitting roll-over frame for tractor - has U-clamps onto rear axle and universal fitting mounting plate
Inventor: KETTLER PAUL ERICH
IPC: B60R21/13
Filed: 1975-03-13
Abstract: The roll-over protection frame for a tractor has a modular structure fitting together, with suitable telescopic sections, to protect any conventional design of cab. The rear ends of the frame are supported on the rear axle by struts which lead through the otherwise unsupported mudguards (24). The struts are located on an L-profile metal plate whose upright flange has securing holes for bolting on the frames and the support struts (20). The horizontal flange has other holes which locate different sizes of U-bolts (16) for securing the plate to the rear axle. The frame can thus be fitted to any conventional design of tractor, even old designs which did not have any mounting points for a roll-over frame.

Title: Screw conveyor for feeding powder under controlled atmosphere - employing screw with non-uniform pitch
Inventor: GRIFFITH JOHN MABIE
IPC: B65G33/26
Filed: 1975-03-26
Abstract: A conveyor for feeding compactible powder into a controlled atmosphere system includes a tube within which rotates a shaft mounted in sealed bearing a tube having an inlet adjacent to one end and opening over the shaft, and an outlet adjacent to the other end and opening below the shaft. Carried on the shaft are two screw flights, the first having a certain pitch at the inlet end of the tube, reducing to a closer pitch in the region of the inlet opening and then reverting to the original pitch which extends to the discharge orifice; the second flight extends from the opposite end of the tube to the discharge and has a pitch reversed relative to that of the first flight. Preferably the pitch adjacent to the inlet is 1 inch and elsewhere is 2 inches; the flights and bore of the tube may be chromium plated. Feeding aluminium powder into a reactor in the production of alcohols. Packing of the powder, and penetration into bearings and seals, is prevented. The shaft (65) is supported in bearings (74) spaced from lip seals (44) and ring seals (45) by wide bore tubes (70) which retain any powder escaping through the seals.

Patent DE-2532082-A1 (DE)
Title: Spinning top with outer sleeve - is actuated by momentum transfer from spinning sleeve to inner flywheel
Inventor: FENEBERG WILHELM
IPC: A63H1/06
Filed: 1975-07-17
Abstract: The flywheel spinning top toy is operated by rolling the sleeve on a level surface, meanwhile holding the cap (5) and the tip (2) between the fingers. The top is then held upright so that the sleeve is still detached from the tip, and released. The sleeve (4) falls down on the tip (2), setting it spinning, together with the flywheel (6), which is connected with the tip (2). The angular momentum of the sleeve is thus redistributed when the entire top spins. The bevelled upper edge of the flywheel mates with the chamfered inner rim of the cap (5) producing a centring friction connection.
Patent DE-2532927-A1 (DE)
Title: Signalling system between main and PBX telephone exchanges - avoids connection loss due to distorted or lost main signalling signal
Inventor: JAEGER HORST
IPC: H04Q3/62
Filed: 1975-07-23
Abstract: The signalling system, is used for signalling between a main telephone exchange and a PBX. It prevents the distortion or loss of the main signalling signal e.g. end of dialling from having detrimental consequences. 50 Hz ac is used for main signalling and AF multiple-freq. signals for secondary signalling. If the first incoming main signal is lost, then the second incoming main signal (free or engaged signal) that follows it is used to replace the first signal. This has the advantage that connections made to the PBX exchange are not lost if the main signal is distorted or lost.

Abstract: The transfer method is for bulky loads from road vehicles to rail vehicles and vice versa and from storage installations to vehicles, being applicable also to water, or aircraft transport. The transfer takes place transverse to the longitudinal axis, with the transfer installation. positioned accordingly. The transfer process is carried out continuously over the whole transfer path using movable sliders fitted with toothed racks, with rotating chains. The reversing and drive wheels of these are supported in a transfer gearbox. The sliders have projections which engage the side of the load to push it between the two vehicles.

Title: Unified bridge system for sewage purificn. installations - has basic design and dimensions of all structures identical
Inventor: HETTLER PAUL
IPC: B01D21/04
Filed: 1975-08-20
Abstract: The bridging system provides for all the structures to be in the same basic form. The lengths are graded down to suit the particular site without alteration of the basic form. Long support beams of the most different form and dimensions can be fitted accurately to the particular loading need. The graduation of the lengths of the structures is identical with that of the pitching of the cross members and the widths of the platform grids, but at the ends of the bridges, the cross members are set back so that the pitch of the last but one cross member corresponds to the width of the platform grid. Design and planning costs for a complete installation are reduced considerably. Numbers of the components will be normal items of stock so that the mfg. costs will also be reduced.

Title: Air cooled trochoidal rotary piston engine casing end plate - has duct with good flow characteristics, and is castable without a core
Inventor: WEEBER HERMANN ING GRAD
IPC: F01C21/10
Filed: 1976-01-10
Abstract: Casing end plate is intended for a type of engine where the charge enters through one casing end plate, flows through axial ducts in the piston and is then fed into the working chamber via a transfer duct in the other end plate. The internal radial boundary of this transfer duct is formed by the main shaft. Its outer boundary lies within the envelope curve of the end seals but there is a deepened outlet portion (5) extending to the boundary line (6) of the working chamber, with a web (7) across it for the seals to bear on. The cover (8) for this outlet section is made separately. The boundary of the outlet opening in the end plate may be taken beyond the normal boundary line of the working chamber, the chamber wall being sloped outwards as necessary. This produces an inward flow component in the charge which has a beneficial effect.
