Patent DE-2744584-A1 (DE)
Title: Joint strips for brick wall building - are used instead of mortar with adhesive for surface bonding
Inventor: MOELLER KURT
IPC: E04B2/02
Filed: 1977-10-04
Abstract: The joint strips are for filling spaces between building blocks or bricks, for forming masonry joints and for full-surfaces force-locking adhesion of building blocks together. Strips are used instead of mortaring with usual types of mortar. They are inlaid inside the layer joint gap areas, between individual brick layers, and cemented with an adhesive over the whole surface to wall thickness, or with breaks. The abutting faces of the bricks are similarly cemented, or cemented without an inlay.

Patent DE-2752518-A1 (DE)
IPC: B28B1/16
Filed: 1977-11-24
Abstract: A moulding box is used, on whose base there are arranged raised areas in the form of webs (3) or of a web grid (6) surrounding depressions (4) in honeycomb configuration, for example made of elastic material. A material layer (7) is then poured into the moulding box, in such a way that the raised areas project above the level of the material layer (7). A mortar mixture (8) is applied onto the material layer (7), which mortar mixture (8) can be introduced if appropriate in two layers (8a, 8b). The mortar mixture (8) has a colour differing from the material layer (7) and determines the colouring of the joint base of the finished artificial stone element. Where the mortar mixture is in two layers (8a, 8b), the layer (8a) adjoining the material layer (7) can be coloured by colouring additives. The material layer (7) and the mortar layer (8) are compacted by pressing or vibration to form an artificial stone element, which can either be removed from the moulding box and set aside to harden completely or can be hardened in the moulding box and then removed. As a result of the different colouring of the joints and of the raised parts, a jointing material differing from the stone elements can be simulated. <IMAGE>

Title: Automatic character classification system - using partial characteristic matching in logical series of operations to read handwritten input sheets
Inventor: SCHNEIDER DIETER DIPL ING
IPC: G06V30/146
Filed: 1977-12-19
Abstract: The method for automati classification of characters enables the characters to be identified to be matched fully or in their essential parts with the corresp. normal or reference characters without extensive operations, thus making practicable the handling of large number of handwritten sheets. Characteristics to be identified are read into stores. Reference characters are held in separate stores. Character data is evaluated for presence and/or position of specific characteristics. Successive operations depend logically on the results of preceding tests. Adjustments are made to allow for character deformation of various types until an adequate match with a reference character is obtd.

Title: Soya protein food from whole beans - by soaking, heating, crushing, homogenising, coagulating and sepg.
Inventor: KUDO SHIRO
IPC: A23L11/00
Filed: 1978-02-03
Abstract: The whole soya beans are soaked in water. The beans are heated at 80-200 degrees C for less than a minute using superheated steam to deactivate the physiologically active substances. The treated beans are than crushed in the presence of water. The prod. thus obtd. is further subdivided into finer particles in a homogeniser to completely destroy the soya cells. A protein coagulating agent is then added to ppte. the protein together with the fat and fibrin. The ppte. is pref. congealed to form a paste prod. or dehydrated to form a powdered prod. Protein coagulating agents specified are edible acids, phosphoric acids and their salts, also calcium and magnesium salts; such as lactic acid, citric acid, Mg or Ca chlorides or sulphates. The prod. is pref. dehydrated by freezing or heating. The process enables a prod. of good taste, not contg. any physiologically harmful material and without any soya smell.

Title: Motor driven impact drill - has striker body working with protrusions on ring forming overload clutch portion
Inventor: SCHRAMM HERIBERT ING GRAD
IPC: B25D11/10
Filed: 1978-02-24
Abstract: The impact drill has a motor in a housing driving a tool spindle via a mechanism which can be changed over between ordinary and impact drilling. When impact drilling, the axial movement of the spindle is generated by a striker body starting to operate only when axial load is applied to the spring-loaded spindle. On the outside of the body are protrusions of a single-or multi-start screwthread, interrupted by passages of the same number as the starts. A corresponding number of components radially outside the protrusions work with them, so as to thrust the body in opposition to a spring and then release it at the passages, whereupon spring action delivers an axial blow to the spindle. The components (44) are stationary protrusions from a first ring(46) mounted in the housing, and which forms an overload clutch in conjunction with a second ring(51) and springs (33, 39).

Title: Safety plug and socket combination - has connecting plates in both parts contacting only after rotation of plug
Inventor: IPACH WOLFGANG
IPC: H01R13/44
Filed: 1978-04-03

Title: Overload protection circuit for inductively loaded push=pull amplifier - prevents occurrence of pulses by blocking drive current splitting transistor during blocking half period of output transistor
Inventor: FACSADY TAMAS
IPC: H03F3/26
Filed: 1978-04-11
Abstract: The application is to class B or AB push pull power amplifiers feeding inductive loads, e.g. sound radiators containing a filter. A transistor (T1) diverts part of the output stage (T4) base signal in the event of an overloaded emitter. To lock out the output stage in the even of high voltage a second transistor (T3) and non-linear two pole (NL2) is added. The second transistor (T3) is reset by a third transistor (T2) connected between the base of the protection transistor (T1) and: the amplifier output (Ki), and linked to the second switching transistor (T3). The circuit gives low audio distortion whilst maintaining effective amplifier protection.

Title: Diagonal seat belt strap sheathing in vehicles - consists of elastic strip with slide-stopping underside surface and lining inside sheath with low coefficient of friction
Inventor: BARTH OTTO MATHIAS
IPC: B60R22/00
Filed: 1978-06-02
Abstract: The device prevents irritating effects on the user's body caused by the diagonal seat belt strap in a motor vehicle. It reduces abrasion of the user's clothing caused by frequent changes of body position. The relevant length of the diagonal strap is enclosed in a sheath which, once in position clings to the user's clothing, but is easily adjustable along the webbing. Also following the change of body position the sheath glides along the webbing while it remains sticking to the user's clothing. The sheath (2) consists of an elastic strip (3) with a thin pliable cover attached to its edges. The cover is folded-over and its edges are closed up by a sliding fastener (2a). The inner surface of the strip (2) is provided with a fabric carrying upstanding bristles (4) on which the webbing (1) glides easily, whereas the outside surface of the strip is fitted with lengths of padding (6) made of plastics foam which tends to cling to clothing.

Title: Pharmaceutical preparations in retard form - with active materials in core having semipermeable coating of film former and polymer
Inventor: STRICKER HERBERT DR
IPC: A61K9/52
Filed: 1978-08-19
Abstract: Pharmaceutical prepn. in retard form comprises a core contg. >=1 active substance together with a carrier or excipient. The core is coated with a semipermeable coating of 20-90% water-insoluble film former (I) (e.g. ethyl cellulose) and 10-80% water-soluble polymer (II), e.g. PVP, PEG or methyl cellulose. The release of active substance is independent of pH in the body fluid over the whole period of its activity. The core pH may be reduced by inclusion of acidic material to reduce disintegration time.
