Title: Current collector for battery cell - is produced by firing projectile which punches through sealing insulation using spring to contact electrode
Inventor: TSUCHIDA TAKASHI
IPC: H01M50/50
Filed: 1973-05-11
Abstract: During the production process of a fully sealed battery cell of the flat cylindrical type, one electrode is overlayed onto a flexible sealing insulator in the form of an inverted cup. In order to provide the electrical connection between the electrolyte and this top electrode, a small billet is punched through the insulation by a spring loaded die tool. The billet comprises a pointed central boss mounted on a circular flange having an outer annular rim projecting in the direction of the pointed head. When fired upwards at the inverted cup insulator, it pierces it and makes contact with the top electrode of the cell on the underside. This flattens the head of the billet giving it a captive inverted cone section, and ensures a good electric contact with the case.

Title: Aligning weight of building in relation to foundation - making use of cavity left under edge region of foundation body
Inventor: GRAVERT FRIEDRICH WILHELM DR I
IPC: E02D35/00
Filed: 1973-07-09
Abstract: This method can be used also for centering and aligning of vertical loads such as high rise building which may have large eccentricities relative to the load bearing centre of the foundation. An edge region under the building is excavated so that it does not participate in supporting the weight of the building. Filling material is injected into this cavity or removed by means of a pipeline. This cavity can be divided into a number of different rooms by a partitioning bulkheads. Each of these rooms can have its own pipelines. Permanent correction is carried out by injecting concrete. A permanent or temporary correction can be carried out by injecting a medium which does not harden and which can be removed again. The cavities used for correction can be designed into the system so that corrections can be carried out if necessary should the conditions under the building undergo continuous change for example due to settlement, outside buildings or due to modification of the buildings.

Title: Plastic sheet fed into drawing plant - by air jets then duct shape changes to give drawing action
Inventor: GAGEUR FRITZ
IPC: B29C55/06
Filed: 1973-09-29
Abstract: A floating feed is used to introduce a (plastic) sheet into a drawing or stretching plant. The drawing duct comprises alternate upper and lower rolls with the spaces between the rolls closed by tilting plates which are initially horizontal, thus forming upper and lower walls to the duct, and air jets feed the sheet into the duct. To change over form the feed to the continuously operating, drawing process, the pivot axes of the plates, lying parallel to the rolls, are raised (for the top plates) and lowered (for the bottom plates) causing the plates to tilt, esp. adopting V-shapes in pairs. By the same movement, the rolls are moved respectively down and up so that they all generally in the same plane, thus providing a meandering path for the sheet between the rolls. Both movements (plate axes and roll axes) are produced by a common linkage. The sheet is thus fed in gently, without contact.

Title: Water bath for heating water-tight food packets - pumps water through system to ensure high rate of heat transfer
IPC: A23L3/10
Filed: 1973-11-21
Abstract: The water batch is mounted on legs and has a central nozzle box which divides the bath into two parts. The sides of the nozzle box are perforated to provide nozzles which emit jets of water supplied by the pump through a pipe. The water returns to the pump via two other pipes. The water tight packets of food which are to be heated are placed on grids within the baskets, which are fully open on the side facing the nozzle box so that the circulation of the water is not impeded. The control box is mounted on the cover above the bath.

Title: Thyristor control for inductive load DC or AC regulator - reduces load on supply by firing thyristors in specified manner
Inventor: GLEIXNER FRANZ DIPL ING
IPC: H02M3/135
Filed: 1974-01-18
Abstract: The control circuit, for an inductive load d.c. or a.c. regulator has a bridge with thyristors. After turning-off, one of the thyristors supplying the load current has its coasting circuit (for the demagnetisation current from the inductive load) open circuited. For a d.c. bridge regulator only one of the two thyristors is turned-off to interrupt the load current. For an a.c. bridge regulator the thyristors are triggered in a specified way so that the load on the supply, and with it the smoothing capacitor, is reduced.

Title: Power potentiometer with increased heat conduction - has resistance element on cover plate and sliding contact spring tensioned against closing cover
Inventor: BOETZ JAKOB
IPC: H01C10/32
Filed: 1974-02-09
Abstract: The potentiometer has a sliding contact movable by a shaft. The contact slides over a resistance element fixed in the housing. The shaft is turnable in a cover part of the housing, which is nearest to the operating knob. The shaft has a fixed follower beyond the operating knob follower, which provides an insulator for slide contact. The resistance element is fixed to the side of the housing cover, away from the operating knob. The slide contact abuts via the slider against the resistance element and via the sliding area flexibly against the metal cover plate. The metal cover plate closes the housing cover part. The arrangement reduces the required number of parts, while provided for heat dissipation.

Title: Concrete mixer with shaking action - having flexibly mounted pistons in walls connected to vibrator
Inventor: PROCHOROW GEROLD N
IPC: B01F11/00
Filed: 1974-05-24
Abstract: Mixer consists of a rigidly mounted vessel esp. cylindrical, with inlet and outlet branches for feed and product, together with a central vertically mounted impeller or a shaft. In the walls mounted in elastic panels are elements or pistons connected to a shaking device. The elements have a protruding blade into the mixer and their outside dia. is less than the length of the impeller shaft. They move horizontally forming vertical planes of motion. The longitudinal axis of the elements is perpendicular to the impeller shaft. The lowest blade of the impeller consists of a rigid mounting plate to which are attached flexible baldes so designed that the rigidity decreases along the length of the blade towards the vessel wall. The mixer is useful for mixing reinforced concrete mixs, esp. drier type mixes. Traditional vibratory mixers used a circular motion but this is unsuitable for water contents below 40%, and does not give complete emptying of the vessel nor effective operation for a partially filled vessel. Present mixer overcomes these problems.
