Title: Filter consisting of frame and plates - providing complete sealing without using high pressure to press sealing surfaces together
Inventor: HARTMANN EWALD
IPC: B01D25/21

Title: Automatic detector of maxima and minima of oscillation - uses peak voltage stores for extreme values
Inventor: WAWRA CARL-MARTIN DIPL ING
IPC: G01N3/36
Filed: 1973-06-20
Abstract: The oscillation is present as an electrical signal. The extreme actual values which have been entered in the peak voltage stores are passed to an evaluation device. The connection is controlled by a clock frequency which is supplied from a frequency generator. The clock frequency controls simultaneously the excitation for the oscillation to be detected, via a multiplier. The detected measured values for the upper and the lower load had to be passed to additional intermediate stores which are not now required. The frequency of the frequency generator is controlled in dependence of the phase position of two electrical signals.

Title: Cleaning machine for long large diameter pipes - has double set of electrically driven rotary brushes
Inventor: HILGER HELMUT
IPC: B08B9/049
Filed: 1973-07-14
Abstract: The machine has a chassis formed of a hollow tube housing an electric motor with a shaft projecting from each end. Bevel gears mounted on each end of the shaft drive radial shafts which, in turn, drive the barrel shaped brushes through bevel gears.

Power is supplied through an electric cable and as the brushes rotate they push the machine along the pipe. When it has reached the end of the pipe the motion can be reversed so that the dirt is swept back to the pipe entrance.

Title: Removing metal coating from parts of metal coated insulator - by subjection to electric current, using inert gas at removal site
Inventor: KOBALE MANFRED DR
IPC: H01G13/06
Filed: 1973-09-25
Abstract: In a method for removing parts of metal coatings by passing a coated substrate past an electrode and subjecting it to short electric impulses of constant amplitude, as in DT 2304124, the improvement consists of blowing a protective gas stream on to the area around the demetallizing electrode. Method is used for removing edge parts of a metal coating from a foil for making capacitors. The protective gas stream reduces the tendency of the removed and adjacent metal to oxidise and prevents the redeposition of metal from the vapour state. The coating metal may be aluminium. The demetallizing electrode is also cooled by the protective gas.

Title: Security system for dress shop changing rooms - has clothes hook connected in electric circuit to detect garments left behind
Inventor: CORDES WERNER
IPC: A47G25/06
Filed: 1973-10-12
Abstract: The clothes hook provided in the changing room pivots when clothes are hung on it, and is associated with a switch so that a circuit including a signal source is closed. The pivot of the clothes hook together with the switch are enclosed in a common housing, with the signal source which may be a lamp, pref. lying outside the housing. The clothes hook may pivot against a biasing spring which ensures that the hook is horizontal when not carrying any weight, in which position the switch is open. This system allows any garments left behind in the changing room to be detected, so that these cannot be subsequently pilfered.

Title: Mechanical indicator for thickness inspection of brake pads - is checked through hole in brake cover
Inventor: GEORGES GERARD
IPC: F16D66/02
Filed: 1973-10-27
Abstract: To measure the thickness of brake pads, a sensing lever with a central pivot is located between extensions of the brake pads which are not in contact with the disc when the brakes are applied. With progressive wear, the gap between the pad extensions decreses thus affecting the angular position of the sensing lever. Two indicator arms which are an integral part of the sensing lever are observable through an inspection hole in the brake cover and also from the under side of the vehicle. Fixed markings related to the indicator arms show when the minimal safe brake pad thickness is reached.

Title: Damping mechanism for window support member - has spring to reduce high opening and closing speeds
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: E05F11/08
Filed: 1974-07-02
Abstract: The damping springs (25, 26) are fitted into a closed housing (11) in which slides the actuating rod (10). These springs may be preloaded and they can have different dimensions. The damping arrangement may become effective only in the last short distance of the travel before the window panel reaches the end position. The actuating rod (10) passes through the end openings (21, 22) of the spring housing and this rod carries within the chamber a block (24) which comes into contact with the spring. In another version the damping effect is achieved by means of rubber collars at the end of the actuating rod guide housing.
