Title: Drilling machine milling unit - has two guides on guide plate, one enclosing milling tool, other curved in front of tool
IPC: B23C7/00
Filed: 1977-05-04
Abstract: The milling unit for use with domestic drilling machines has a holder for clamping to the machine throat. The holder is for a bearing plate through which passes the milling shaft. A guide angle for the workpiece, which can tilt on the plate, has a guide plate locating on the bearer plate and forming a side of the workpiece location space. To the milling unit are fixed two exchangeable guide pieces to locate on the guide plate (18), and which define the second side of the workpiece location space. One of these has two locating surfaces which enclose the milling head (10) in the advance driection. The other guide piece (26) has a short, convexly curved workpiece location surface (29) located in front of the milling head outer face side.

Title: Self feathering propeller for sailing boat auxiliary drive - has blades rotatable about spindle extending radially from sleeve to which torque is transmitted by pintles on hub
Inventor: HIRSCHBERGER CARL R
IPC: B63H3/00
Filed: 1977-07-30
Abstract: The propeller blades are loosely supported by and rotatable about individual spindles, extending radially from a sleeve which is rotatable about a hub secured to the propeller shaft. The hub carries pintles which serve to transmit torque from the shaft to the sleeve. The pintles also position the blades for reverse thrust when the shaft is rotated in the astern direction. Stops extending from the sleeve serve to limit the rotation of the blades to provide a forward thrust when the propeller shaft is rotated in the ahead direction.

The rib cross-section can join smoothly onto the pipe wall, being so formed as to give good adhesion with the protective cladding. The internal radius of the rib at the apex can be roughly 0.08 times the pipe diameter while the radius where it joins the main part of the pipe wall can be 0.05 times this diameter. Inside it can be bridged by a sheet-metal strip, in line with the inside of the pipe wall.

Title: Bonding polymer layers to produce honeycomb materials - where adhesive is localised by using diluted solvent free from plasticiser; esp. for heat exchangers
Inventor: RENNEBECK KLAUS ING GRAD
IPC: F28D19/04
Filed: 1978-05-26
Abstract: Honeycomb structures, for heat exchangers, and partic. enthalpy pumps, scrubbers, sound insulation, trickle separators etc., have flat sheets or shapes in films, profiles or mouldings bonded together to form flow passages, using cellulose acetate, polyamide, polycarbonate, polystyrene, PVC, PVA, ABS etc. The components are free from plasticiser, their constituents are solvent-bonded together, flat or by winding together, or are briefly dipped in solvent after laying flat or winding together; the solvent is retarded in its action by diluting with liquids or by partly saturating with dissolved solids which are also free from plasticiser. The structures are cheaply produced, stable, of low weight and high mechanical strength, and versatile in application.
Patent DE-2831735-A1 (DE)
Inventor: BERCOVITZ CHRISTIAN
IPC: G07D7/00
Filed: 1978-07-19
Abstract: The sheet-like security (2), for example a banknote, is transported, by means of a conveyor device (6, 7) driven by a motor (5), through the collecting channel of a test unit to a test apparatus not shown here. The proposed apparatus has a preselection device (1) which is controlled by a detector (3) and records an adjustment of the motor (5) measured by a measuring and control circuit (4) and which, when the preselected adjustment value is reached, transmits a signal to a control circuit (8) for initiating the test operation at the point on the security (2) thus located. The preselection device (1) is an electronic preselection counter. The motor (5) is a stepping motor or a continuously rotating motor. To determine a plurality of measuring points, there is a preselection device (1) which allows a preselection of different numbers of steps or values of the angular adjustment of the motor (5). The test apparatus is adjustable transversely relative to the conveyor device. The measuring and control circuit (4), the preselection device (1) and the control circuit (8) are formed via a microcomputer. <IMAGE>

Title: Multi-pane glazing using three or more panes - esp. for buildings or motor vehicles, where inner plastic pane provides high resistance to impact and theft
IPC: B32B17/10
Filed: 1978-08-14
Abstract: The panes are sepd. from each other by spacers bonded to the panes via an adhesive which possesses an adhesion strength >5 kg/cm in a peel test, and a creep elongation of >=3%, when employed to bond glass to plastic or metal or metal to plastic. A pref. pane assembly uses outer glass panes (I) which are >=3 mm larger than the inner plastic panes, which are made of polycarbonate or ionomer resin. The outer panes (I) pref. consist of silicate glass and/or safety glass; and one pane (I) may be thicker than the other pane (I). The spacers are pref. bonded by the adhesive to panes (I); and the cavity formed due to the smaller pane is filled with the same adhesive or another sealant. One pane (I) may consist of armoured glass whereas the other pane (I) is covered by a shatter-proof foil. For example, a plastic pane is located between two glass panes so the assembly is highly resistant to impact. Panes (I) can be made of toughened glass; and an alarm may be located in the assembly, i.e. an anti-theft device of known type.

Title: Pipe flange forming device - uses ram and mandrel for flaring of pipe end prior to pressing operation
IPC: B21K21/12
Filed: 1978-09-01
Abstract: The device for cold forming of flange end on pipes consists of a drop forging block (1) with cylindrical bore (2) into which the pipe end (3) is inserted with loose fitting.

Title: Helical induction coil for heating rod and similar workpieces - where internal part of coil is wound from solid rod to obtain small bore dia. for coil
Inventor: GEISEL HERBERT
IPC: H05B6/42
Filed: 1979-05-26

Title: High temp. ribbed heat exchanger pipe - has ribs formed by separate discs locked onto pipe using tapered, slotted bushes
Inventor: WIESER RUDOLF DR
IPC: F28F1/24
Filed: 1979-05-28
Abstract: Pipes for superheated steam, high temperature heat exchangers etc., are fitted with discs (3) acting as heat conducting fins. Between each disc and the pipe is inserted a slotted, tapered bush (2). The outside of the pipe is ground with a fine finish, and the bushes grip the pipe due to their resilience. A thinner ridge (3") is formed around the edge of each disc, giving a shoulder each side. These enable a ring (4) to be mounted between each pair of discs, to protect the pipe from excess heat. In another design, the discs are flanged, so that separate protective rings are not required. The design can be used for bends.
Patent DE-2921946-A1 (DE)
Title: Video tape time code display - is updated periodically on slow or fast and supplemented by frame pulse on normal speed
Inventor: HEILMANN JOERG BERNHARD DR
IPC: G11B27/34
Filed: 1979-05-30
Abstract: The time code data signal recorded along a video tape often has gaps in it. A reliable display of the time code is obtained, when replaying such a tape on a video tape machine, by loading the output of the code reader into a register which drives the display. In the PLAY position of the function switch, a frame synchronisation pulse is fed to the register to increment its contents like a counter and maintain correct display during gaps. In the SHUTTLE, FAST and SLOW functions, no synchronisation pulse is fed in and the code reader is controlled by a time delay circuit. The code reader now updates the register every Nth frame, where N depends on which function is selected.

Filed: 1979-07-19
Abstract: The bayonet coupling secures the dish portion of a wall or ceiling light fitting to a bracket. It has bosses engaging behind a transverse flange on the neck of the dish, which protrudes outwards. These bosses (3) are spring-loaded against the neck (6) of the dish (5), and can be formed by spring pins sliding in the lengthwise direction or alternatively by curved leaf springs. They can be arranged to engage between fixed stops on the neck, riding up over ramps formed on the front ones. Other ramps can also be formed on the underside of the flange (7) so that, when the dish is turned into the engaged position, the flange is pressed against the bracket.
