Title: Precision shaft bearing for small motors - has triangular arrangement of wear-resistant plastics bands holding shaft with three-point contact
Inventor: PFEIFER HERMANN
IPC: F16C33/20
Filed: 1977-03-17
Abstract: The shaft bearing for fractional horsepower DC motors is designed for ease of manufacture and installations. It maintains close tolerance in operation which is essential for applications such as in motorised cameras, clock etc. The end cap of the motor housing has an extension (3) which accommodates the shaft bearing (4). The bearing comprises a number of symmetrically arranged webs (7) whose outer ends are held by the cap flange. The webs hold flat bands (5) of equal length in the form of an equilateral triangle, each side being held under tension against the motor shaft (6). The straps may be formed as a one-piece plastics moulding using injection techniques. The material used is impact- and wear-resistant plastics such as polyamide. The flat bands are made convex in the region of the shaft so that the contact area is minimised.

Title: IC engine fuel injection valve - has axial bore leading to combustion chamber for test purposes
Inventor: KANZLER HANS
IPC: G01L23/00
Filed: 1977-04-26
Abstract: The conventional fuel injector valve has an axial bore (7) for pressure metering purposes. The bore (17) starts close to the fuel injection nozzle tip to communicate with the combustion chamber and terminates outside the injector casing. The bore can either contain an electrical conductor to feed signals from a temp. or pressure responsive transducer (8) fixed to the nozzle tip to a connection, or be filled with a hydraulic fluid to transfer pressure impulses. The impulses are fed to a recorder to compare actual engines conditions with rated conditions. The combustion chamber pressures and temperatures are taken when the engine is turned at starter motor speed 600 to 800 revolutions per minute without fuel feed.

Title: Coated fleece material perforating arrangement - uses spark erosion needles to improve its ability to let through water vapour
Inventor: ENGEL HANS-KARL V
IPC: B26F1/28
Filed: 1977-09-09
Abstract: The spark erosion machine is used to form a row of holes through a coated fleece material to allow water to pass through.

Title: Circular metal saw with tooth inserts - has industrial diamond plates on tip of some projecting teeth with hard metal underlay
Inventor: LACH JAKOB
IPC: B28D5/02
Filed: 1978-03-28
Abstract: The projecting teeth have part of the face and part of the heel formed by diamond plates (20). The teeth protrude beyond the remainder by the thickness of their diamond plates. Each plate is bedded on an underlay of hard metal (18), itself let into the hard metal tip (14) on the basic tooth below. The leading edge of the diamond plates projects beyond the tooth face area formed by the cutting faces of the hardmetal tips (14) and the hardmetal underlay. The diamond plate itself is preferably in the form of a block and can be made from industrial diamond. The saw reduces the amount of fine toxic respirable dust produced by cutting. The projecting diamond teeth produce a coarse large area cut. The recessed teeth which follow do the fine cutting, but without making excessive dust and also leaving a fine surface finish.

Title: Prodn. of longitudinally sealed watertight communications cables - using pressure chamber vibrated during filling together with sealing substance
Inventor: VOGTS ARNOLD ING GRAD
IPC: H01B13/32
Filed: 1978-04-20
Abstract: The cores of the communications cable are plastics insulated, and the spaces within the cable are filled with a sealant which sticks to the core insulation and to the cable sheath. The filling process uses a pressure chamber (4) in which the sealang is forced into the cable sheath. During filling the pressure chamber and/or the sealant are vibrated. Inside the pressure chamber the sheathed cable (5) is preferably passed between pairs of rollers for deformation into a flattened cross section. The roller pairs may also be vibrated during the process. The sealant may be fed into the pressure chamber via a reservoir of variable volume. The process provides complete filling of the inner cable spaces independently of the number cores.

Title: Sliding disc for gate valve - has seal rings inserted by rollers with axial force balanced by radial wedges
Inventor: PLATTES CLEMENS
IPC: B23P11/00
Filed: 1979-04-26
Abstract: The sliding disc (4) of a gate valve is mae of cast iron with resilient flanges with grooves (13) in the end faces for sealing rings (12). These sealing rings (12) are pressed into the grooves by means of rollers (11) which exert a high axial force on the disc. This axial force is liable to damage the resilient flanges so they are supported during the rolling operation by a number of radially arranged wedges (2). These wedges are pushed radially inwards by compression springs (3) so that an axial force is exerted between the flanges to counteract the rolling force.

Patent DE-2929428-A1 (DE)
Inventor: MEILLER HERMANN
IPC: A47C1/022
Filed: 1979-07-20
Abstract: In a seat having a seat plate of adjustable inclination and a backrest of adjustable inclination, gas springs are provided for adjusting the inclination of the seat plate and backrest, the valve actuating pins of the gas springs being oppositely disposed and actuatable by an adjusting lever. The adjusting lever extends transversely to the valve actuating pin arrangement and is mounted to pivot vertically and horizontally about a common pivot point disposed beyond the straight connecting line between the valve actuating pins. In the preferred embodiment, two control arms on the seat carrier are movable in a scissor-like manner in a vertical plane containing the valve pin arrangement, the adjusting lever engaging between and co-operating with the control arms which co-operate with the valve actuating pins. This permits the inclination of the seat plate and the inclination of the backrest to be adjusted with a single operating element either at independent times or simultaneously.
