Title: Noise reducing blower housing directing flow through right angle - has deflector surfaces positioned within specified rotor dia. part relative its circumference
Inventor: COESTER ROBERT DR
IPC: F04D17/04
Filed: 1977-10-18
Abstract: Housing for blower directing flow at right angles is designed to reduce the noise level without abandoning the advantage of a stable pressure characteristic. It comprises two side sheets and two deflectors (a, b). The distances (d1 and d2) of both deflectors from the rotor circumference at their nearest point (A, B) to the rotor are less than 5% of the rotor diameter. The deflector surface (b) lying opposite the rotor circumference is shaped as a double wall with intermediary chamber so that the part (b1) lying nearest the circumference permits the passage of air but executes a known resistance to the throughflow. This wall section (b1) extends from the pressure chamber (D) via the point (B) of closest approach to the rotor circumference to the suction chamber (S).

Title: Prestressing system for cast, nuclear reactor hot pressure vessel - using stressing cables mounted on externally located insulation
Inventor: GABREA RADO DIPL ING
IPC: G21C13/087
Filed: 1978-10-19
Abstract: Cast cylindrical pressure vessel of nuclear reactor type having external pressure-tight insulation with circumferential cables outside it, has vertical cables also outside which pass through tunnels in cast distance-pieces mounted on the insulation. These distance-pieces carry the circumferential winding and transmit its pre-stressing force to the insulation and underlying shell. Pref. the ends of the vertical cables are fixed to anchoring rings after passing through these rings in an inwardly canted direction. The rings themselves have additional pressure-tight insulation at their boundary with the cover-plates. Rings, insulation, and coverplate are bolted together. No insulation or cooling of individual vertically-running cables is required so that access for inspection and routine testing is assured, e.g. through additional apertures in the distance-pieces running at right-angles to the cable tunnels. Simplification of design can result in 25% saving in weight and correspondingly in cost. Also the arrangement produces low temp. gradients in the cast shell and prevents high temp. creep damage in the cables.

Title: Automatic message delivery concerning next station - has tape recorded messages indicating next stop of train or bus which is triggered by track-side unit
Inventor: ERMECKE ALBIN
IPC: B61L3/00
Filed: 1979-02-12
Abstract: A pre-recorded message system for use with road and rail, transport allows information regarding a specific stop to be announced to passengers. In the case of rail transport a number of permanent magnets may be located at specific intervals along the tracks to energise coils mounted on the train to activate a tape player carrying prerecorded messages. An alternative is to use a current bridge strap (33) that is contacted by a pendulum contact (31) located on the train. As the pendulum makes contact, current is transferred via flexible coils to a solenoid activator (8). This causes contacts to be closed (10) and the tape drive engaged. A pre-recorded statement of the next stop to be made is played over loudspeakers located in each carraige.

Title: Silver halide photographic emulsion prodn. - by including aq. silver salt and ammonia solns. in process steps to obtain optimum emulsion crystals (BE 16.8.79)
Inventor: MATERNAGHAN TREVOR JAMES
IPC: G03C1/005
Filed: 1979-02-14
Abstract: The parent patent described the prodn. of photographic Ag halide (AgX) emulsions contg. twinned AgX crystals by a series of stages involving (a) formation of AgX crystals contg. min. 90 mole% iodide in a colloidal dispersion medium (I); (b) mixing with an aq. Ag salt soln. (II) and an aq. alkali and/or ammonium bromide and/or chloride soln. (III), so that twinned crystals form; (c) treating (I) with a AgX solvent, so that the twinned crystals grow by Ostwald ripening; opt. (d) allowing the twinned crystals to grow by adding more (II) and (III); and opt. (e) removing the water-soluble salts formed and sensitising the emulsion chemically. In this addn., the novel features are that, in (b) (II) and (III) are added at such a rate that the AgX crystals formed in this stage are predominantly twinned and stage (c) is omitted. The fraction of twinned crystals with parallel twinning planes is increased, giving emulsions suitable for graphic work and radiography. The developed emulsions have high covering power and high contrast. The emulsions can be used in X-ray films, black and white and colour films for cameras, photographic papers and direct positive materials.

Patent DE-2927857-A1 (DE)
Title: Workpiece conveyor between machining stations - has halting and transfer mechanisms for each station served
Inventor: MUELLER KARL
IPC: B65G47/48
Filed: 1979-07-10
Abstract: The conveyor with local buffer effect connects stations machining workpieces, there being several successive stations performing the same operation, and which are followed by others performing different ones. The workpieces are transported on carriers returned empty to the initial station from the last one. A single conveyor (1) with forward and return runs extends past all the stations, and has for each station a halting (26) and a transfer (3a,3b) mechanism. With stations performing the same operation and during machining of a workpiece (8-10) all the halting mechanisms except that of the last one allow the carriers (13-15) to pass through. When a workpiece is transferred, the transfer mechanism makes a mark on its respective carrier, which prevents it being transferred for machining into any of the other stations. Thus it travels past them and to a station performing the next operation.
Patent DE-2931565-A1 (DE)
Title: Alerting device for motorcycle direction indicators - gives rider tactile indication in handgrip that indicators are operating
Inventor: LEITNER FRIEDRICH
IPC: B62J6/00
Filed: 1979-08-03
Abstract: The alerting device comes into operation when the indicating lights are on and remains out of operation when the power transmission of the motor-bike is interrupted. The device passes a kinetic signal to an elastic rubber handgrip. To prevent the rider experiencing discomfort as a result of the distorted handgrip, the kinetic signal is applied in pulse-form in a radial direction to the handgrip (2). The kinetic signal is directed towards the inside wall of the handgrip and is produced by an electromagnetic (3) driving a reciprocating rod (4). The end of the rod is coupled to a pivoted arm (6) that distorts the rubber sleeve (2) of the handgrip and extends with its free end through a hole in the tubular-metal inside-part (1) of the handgrip.

Title: Fishing rod reel anti-return lock - has setting member in clearance fit in fork of catch
Inventor: VOLKERT BERND
IPC: A01K89/01
Filed: 1979-09-06
Abstract: The sprung setting member gives two end positions in a housing for a catch hinge on a spindle parallel to a drive spindle. It one end position this locks a wheel, also acting as a ratchet, fixed to a driven spindle. The free end of the member (30) is a clearance fit in a fork (28,29) in the catch (25), while its other end slides along the housing wall (31) and is lockable in a middle position (33). The fork width is at least as great as the amount of movement of the locking portion of the catch on the side of the catch spindle (26) furthest from the drive spindle (12). A circlip is in frictional conact with the drive spindle, its leading end (36) in the winding direction (14) being bent over, so as to engage in a catch slot (35). The spring force of the circlip is less than that of the setting member, which in its first end position (32) thrusts the catch into the locking position.
