Title: Expanding anchor bolt socket - has transverse recesses forming profiled portion at end adjacent to expansion cone
Inventor: STERNISA DANILO ING GRAD
IPC: F16B13/06
Filed: 1980-08-16
Abstract: The expanding anchor socket comprises a slotted sleeve, internally chamfered at the insertion end, and through which a bolt extends, having at the insertion end a cone protruding beyond the sleeve. At the end adjacent to the cone (4) the sleeve (1) has a profiled portion formed by transverse recesses (9). The transverse recesses can be formed by grooves extending round the periphery between the slots, and of wedge-shaped cross-section increasing in depth towards the insertion end, where they end in a rounded portion level with the internal chamfer. Thus there is an annular bead with a sharp edge on the outside, formed on the sleeve end where the cone acts against it.

Title: Spacer for lead acid battery plates - is spring loaded bearing plate of acid resistant plastics
Inventor: WIEDERSUM GERHARD
IPC: H01M10/16
Filed: 1980-10-23
Abstract: A spacer for an accumulator, esp. a lead-acid battery, is inserted between the last plate (4) of the battery and the end wall of the casing (6). The spacer consists of a plate (5) bearing against the electrode plate (4) and of an elastic spring member (11) having its edges (7,8) bearing against this plate (5). The elastic member is pref. arc-shaped with its edges curved inwards. This arrangement enables batteries of various numbers of plates to be made up without the need to have a casing of the exact dimensions for each battery; instead the spring-acting spacer is fitted at the end of the stack of plates. Moreover, the arrangement shown is adaptable to different widths of battery. Prefd. material for the arc-shaped spring (11) is a sulphuric acid-resistant plastics, such as polyolefin or PVC, and the plate (5) may be of the same material. The plate (5) has stops (9,10) into which the ends of the spring can be engaged.

Title: Oesophagus stethoscope monitoring breathing and heart beat - has thin-walled bag at end of inserted probe contacting oesophagus walls
Inventor: KESSLER GERHARD DR
IPC: A61B7/02
Filed: 1980-11-22
Abstract: The stethoscope has a probe (1) inserted in the oesophagus so that its pick-up microphone (6) at the proximal end of the probe (1) provides signals representing the lung motion and the heart beat. The microphone (6) is coupled to an electroacoustic reproduction system (12), e.g. a cassette recorder. Pref. the probe (1) comprises a hollow tube closed at the distal end, with a thin-walled bag (2) adjacent this end which contacts the walls of the oesophagus and monitors the lung and heart movement. The microphone (6) is carried by tubular insert fitted into the proximal end of the tube, its signal pref. fed to a 2-channel amplifier which allows the amplification of the lung and heart noise to be adjusted separately. The stethoscope is easy to sterilise and precisely monitors both the heart and lungs.
Patent DE-3044637-A1 (DE)
Title: Winding machine for small armatures - has locating pin and clamp for correct positioning and lever for turning core
Inventor: REDECKER KARL-GEORG
IPC: H02K15/095
Filed: 1980-11-27
Abstract: The machine typically winds coils onto three pole armatures. The proposed mechanism accurately positions the armature so that each pole is wound in turn from one continuous wire feed. The mechanism has a lever operated clamp which engages with the armature shaft and supports the armature in the correct position relative to the wire feed. A plunger is profiled to engage with two adjacent pole tips simultaneously in order to hold the armature in a defined angular position w.r.t. the wire feed. Finally the mechanism has a further lever system for turning the armature through one pole pitch. Typically, it engages with a pole tip to push the armature round, and n on the return stroke turns on a pivot so that no force is then exerted on the tip. Several such mechanisms together with wire feeds can be arranged on one base and controlled by one programmer.

Title: Zoom binoculars
Inventor: SHIMIZU FUMIO
IPC: G02B7/06
Filed: 1981-12-24
Abstract: The aim is to facilitate the manual zoom setting in zoom binoculars having a sliding mechanism for the lens group for setting the zoom. This is achieved according to the invention when a shaft (13) of a knob (1) for zoom setting, which can be moved only in a rotary fashion, and an end of a sliding rod (4), which can execute only a straight advance in the axial direction, are screwed together. Furthermore, a groove (5) is formed on the other end of the sliding rod (4) in a direction at a right-angle to the direction of movement, and a groove (9) is formed on a connection (10) for setting the zoom, which slides the zoom lens group for the purpose of magnification, causing a straight advance at a right-angle to the direction of movement. Finally pins (6, 6') are mounted on both ends of a lever (7) which are fitted in a sliding and rotating fashion in the two grooves. <IMAGE>

Title: Device for improving the fuel feed to the cylinders of an internal combustion engine
IPC: F02M35/10
Filed: 1981-12-28
Abstract: In the inlet ducts of an internal combustion engine, particularly one operated with alcohol, a liquid film of fuel usually condenses which ultimately pours into the combustion chamber and is there burnt only slowly and incompletely, which represents a considerable waste of fuel. This is here avoided by a pot, beaker or the like with passage provided in the base inserted into the inlet duct, tightly abutting its internal walls and catching the fuel precipitate.

Title: Adhesive plaster and process for the production of an adhesive plaster
Inventor: ISHIGURO SHOZO
IPC: A61K9/70
Filed: 1982-01-28
Abstract: The invention relates to an adhesive plaster consisting of a backing and of an adhesive impregnation applied thereto in order to improve the action of a medicament by uptake thereof through the skin and application and sealing thereof on the skin; the medicament is applied distributed in a spaced relationship and is present in the same quantity in predetermined surface zones; the medicament is covered with a protective coating. The invention furthermore relates to an efficient production process for the adhesive plaster.

Patent DE-3208452-A1 (DE)
Title: Method for fitting a crack stopper to a pipeline, and a pipeline with a crack stopper
Inventor: JONES BRIAN LAWRENCE
IPC: F16L57/02
Filed: 1982-03-09
Abstract: A crack stopper on a high-pressure pipeline is proposed, as well as a method for fitting the same. A cylindrical sleeve is initially fitted to the pipeline. It has an upper and a lower opening. The ends of the sleeve are sealed with a plastic strip or the like, and reinforcing strips are fitted thereto. At this point, a urethane-elastomer filling material is pressed through the lower opening in order to fill the annular space between the sleeve and the outer surface of the pipe. The material is pumped into the annular space until it flows out of the upper opening. Once the material has cured, the reinforcing strips are removed. The filling material results in the stopper sticking on the pipeline in order to prevent sliding out in the longitudinal direction of the sleeve if a crack should occur. The filling material also prevents corrosion between the sleeve and the pipeline.
