Title: Group counting article on balance - uses digital processing of wt. signal to derive item reference wt.
Inventor: ROCK FRANK CHARLES
IPC: G01G19/42
Filed: 1976-04-06
Abstract: The counting balance is designed to find weight of a sample and count a large unknown quantity of objects with a high degree of accuracy. An electrical signal representing the wt. of goods on the balance is generated and converted into a series of signals which are stored so that at each instant the oldest stored signal is replaced by the newest. An average mean instantaneous wt. signal is obtained in digital form. By holding the digital signal at a certain level with no wt. on the pan and continually monitoring it a single item reference value can be derived for counting articles.

Title: Sealing profile for door lower edge - has lever and spring exerting closing force on seal near floor
Inventor: SAEGER KARL-HEINZ
IPC: E06B7/20
Filed: 1976-06-19
Abstract: The sealing arrangement is used for gap between the door lower edge and the floor. The sealing profile is guided in an inclined slot and it can be lowered against spring force. The lowering movement of the sealing profile starts only briefly before the door is closed. The contact point between the sealing profile and the force exerting lever is curved so that at the beginning of the lowering movement of the sealing profile the lever partly contacts the sealing profile. The sealing profile is loaded only after that over its whole length and hence it is guided to its end position. The lever effect is initially low and when the sealing profile moves near the floor, then the lever effect is magnified.

Title: AC vibrator type hand polisher - in which polishing plate and magnet armature move in opposite directions
Inventor: RUETTIMANN ERNST DIPL ING
IPC: B24B23/04
Filed: 1976-10-08
Abstract: The movement of the magnet armature (3) is transferred by a centre pivoted lever (14) to the polishing plate (13), so that the vibrating movement of the armature is in the opposite phase to that of the polishing plate and the inertia forces of these parts are cancelled out. The top part of the level and the armature are shaped so that armature and magnet cannot touch one another. The noise level of the polisher is thereby greatly reduced. This level can be further reduced if the oscillating lever is made from a plastic material. A spring (16) is mounted in the assembly which takes up the play between parts and reduces wear.
Patent DE-2649999-A1 (DE)
Title: Sound insulating hollow partition wall construction - with surfaces in contact coated with a plastic flock to reduce noise
Inventor: SEIFFERT JOACHIM
IPC: E04B2/74
Filed: 1976-10-30
Abstract: Vertical C-section metal wall frame members are coated with an upstanding polyamide fibre flock, electrostatically applied and anchored to the metal with a two-part adhesive. Plaster wall-boards, where they are in contact with the frame are similarly coated, as are any mounting frame members and brackets. The flock separates the contact surfaces of the various components and effectively reduces mechanical transmission of sound through the partition. A particular application is the mounting of sanitary units subject to water noises. The adhesive coating also prevents corrosion. Sound insulation is achieved without the need for solidly built walls.

Patent DE-2719667-A1 (DE)
Title: Recovery of metal from effluent in electrolytic process - with mechanical sepn. of metal from cathode
Inventor: KAMMEL ROLAND PROF DR ING DR
IPC: C02F1/461
Filed: 1977-05-03
Abstract: Metal present in the effluent from a process such as a galvanising bath is recovered electrolytically. The effluent is fed into vessel containing rotating cathodes in the form of rods mounted in a holder driven by a motor. The anodes consist of plates close to but outside the cathodes and a central cylinder. The rods fit at their ends in channels in the holder and are free to roll around the channel. The latter is partitioned which limits the travel of the rods relative to the holders. In each segment so formed, there is a void to allow the rods to move. As the rods move through the upper or lower central position, they fall through the void and are stopped suddenly against the partition or the adjoining rod. This motion shakes free the deposited metal which then falls to the bottom of the vessel. The outlet stream can be taken through a central perforated pipe via an annular basket filled with electrically conducting particles. The metal particles are prevented from forming a deposit on the conical floor of the vessel by two rotating arms which direct jets of electrolyte at the floor towards the centre. The particles then fall through the central outlet into a collecting vessel or recycling process. Because of the continuous agitation of the electrolyte and the close proximity of the cathodes and anodes, a virtually total recovery of the metal is achieved with very loq energy consumption. Furthermore, since the cathodes are continually cleaned of deposited metal, there is no need to change them and a continuous process is ensured.
Patent DE-2722470-A1 (DE)
Title: Even illumination device for surfaces - has wedge-shaped discs formed by two facing faces joined together at one end
IPC: F21V7/05
Filed: 1977-05-18
Abstract: The wedge disc arrangement is used to illuminate surfaces homogeneously by means of spot light sources arranged at the side. The discs (1, 2) consists of artificial glass processing optical properties calculated for best floodlighting. The wedge discs are made by injection stamping using a suitable jet mould. During the freezing-in stage the material is loaded with additional pressure, so that the pressure in the material is maintained after the flow of material has been switched off, before the still partly open mould has closed. The wedge discs made in this way require no further mechanical processing.

Title: Seat belt tensioning mechanism - has electrically ignited explosive charge acting on spool in coiling direction
Inventor: LINDBLAD OSKAR LENNART
IPC: B60R22/46
Filed: 1977-06-07
Abstract: The seat belt tensioning mechanism is activated by a sensor assembly which in case of sudden deceleration of the vehicle emits an electric impulse which ignites an explosive charge. The gas pressure produced by the explosion drives the spool in coiling-on direction. Simultaneously a blocking mechanism is operated which provents the coiling-off of the belt. The mechanism comprises catch arm (7) working together with cam (3). The catch arm is provided with bore (10) closed up at the base by cover (12). The bore contains an explosive charge (11) which can be ignited by primer assembly (13) when it receives an electric impulse via wire (14) from a sensor assembly reacting to deceleration of the vehicle. The expanding gases following the ignition of the explosive charge act on surface (3a) of the rotary cam (3) which is set into rotation and spool (4) takes up any seat belt slack previously in exist tence. At the same time the catch arm (7) swings out in opposite direction than the rotation of the spool and moves into meshing position another catch on the other end of the spool axle.
