Title: Storm brake for large rail mounted machine - uses compression spring to increase brake pad engagement on rail upper surface
Inventor: ROOS HORST-JOSEF DR
IPC: B61H7/02
Filed: 1977-04-09
Abstract: The lower housing section (1) contains a vertically and horizontally movable brake shoe (5), with upper curved (7) and sloping side sections (8). A roller guide (11) on the housing has a turntable, vertically displaceable actuating roller (10) to engage on the curved section. A compression spring (12), pressed against an upper housing plate (13) acts onto the roller. A retraction plunger (14) to return the roller, is hinged to a working cylinder (16). A brake pad (4) positioned below the brake shoe, and hinged to it. With release of the device by wind force, the roller moves along the brake shoe and compression of the spring increases the force, with which the brake pad engages on the rail (2).

Title: Wind turbine with horizontal impeller - has hemispherical blades hinged to close together into complete circle in storm conditions
Inventor: HERTER ERICH
IPC: F03D3/06
Filed: 1977-04-20
Abstract: The wind turbine has a vertical axis (2) with blades (1) held on arms projecting radially from the axis. The blades are hollow and of spherical section. On the forward part of their motion the wind enters the concave side and is reversed by the blade to produce a large change in momentum and therefore driving force. On the return section of the rotation the wind strikes the convex side and passes over it with little resistance. The arms (3) carrying the blades are hinged so that the blades can be closed together to form a complete circle presenting only the convex sides to the wind. This is done in storm conditions to prevent excessive forces damaging the turbine.
Patent DE-2719579-A1 (DE)
Title: Bactericidal spray for freshly slaughtered hog carcasses - which are being chilled comprises an aq. chlorine dioxide of nonbleaching concn.
Inventor: SVOBODA DONALD J
IPC: A23B4/08
Filed: 1977-05-02
Abstract: The carcasses are treated by spraying them with a spray of aqs. ClO2 in a concn. sufficient to prevent the protein synthesis mechanism of bacteria on the skin surface but insufficient to bleach the skin pigment. The hog carcasses are then transferred to a chilling room and the soln. sprayed on intermittently,. while the carcasses are being chilled, for a period sufficient to prevent the protein synthesis mechanism but not long enough to bleach. By using the (dilute) solns., bleaching is avoided while maintaining bactericidal/bacteriostatic action. Off-odours and flavours are also avoided.
Patent DE-2719603-A1 (DE)
Title: Hide stretching system - using pattern of triangular cuts in specified rows and spacings
Inventor: MUENZNER HANS
IPC: C14B15/10
Filed: 1977-05-02
Abstract: A pattern of triangular cuts is slit or cut into the leather side of hides in consecutive rows in the principal direction of elongation and with apices next to each other across it. The distance of the apices is equal to the vertical distance of the legs of two consecutive cuts in the principal directions. The apices are in the opposite direction in alternate rows and offset by half the apex distance. This increases the hide surface area, not only by up to 90% in the principal direction of elongation, but also by 15-20% across it.

Title: Switching circuit for TV receiver - derives setting value from pulse voltage of isolating transformer primary in amplitude rectifier for protection of output voltage rise
Inventor: NAPP GERHARD
IPC: H02M3/335
Filed: 1977-06-16
Abstract: The circuit has an isolating transformer (6), a periodically conductive switch, a feedback path (7, 16) derived from the transformer primary for the switch control, and a stabilising circuit (12) for output voltages. The circuit provides protection against heavy rise of output voltages (U1, U2). The protection is obtained by deriving a setting value (U5) from the pulse voltage on the primary side of the isolating transformer in an amplitude rectifier (14). If a threshold value has been exceeded, the setting value blocks the feedback path via an electronic switch (16) in series with the feedback path. The rectifier is preferably coupled to a coil (11), supplying the stabilising circuit.

The gases from the oxychlorination stage have been purified to remove chlorinated hydrocarbons, water and HCl by condensn. By preheating to this higher temp. prodn. of byprods. such as chloral and chloro-ethanols is reduced without affecting the selectively for (I).

Title: Mining or tunnelling machine ventilation system - has pushbuttons to clean filter, then restart dust removal and stop air blast
Inventor: HOELTER HEINZ
IPC: E21F5/20
Filed: 1977-08-26
Abstract: The ventilation and dust removal system for mining and tunnelling operations uses a dust removal unit (3) at roof level and a blower unit at low level with an air supply duct (4) and perforated discharge section (5) with a swinging flap at the front. These are immediately behind the cutting machine (2). The control system has a push button which enables the operator to shut off the filter and discharge air under pressure to clean it.

Title: Surface coating moulded articles, esp. switchgear - by pre-coating inner walls of mould with material forming surface layer
Inventor: KUTSCHERA KURT DIPL ING
IPC: B29C39/20
Filed: 1977-09-20
Abstract: A moulded article of a heat-hardening resin or foam, with a special surface layer, is prepd. by (a) pre-heating, to above the hardening temp. of the resin of foam, an agent for forming the special surface layer, esp. a very reactive casting resin compsn.; (b) introducing this into the mould, in a liquid state, to (partly) fill the mould; and (c) cooling the surface-forming agent and heating the walls of the mould, so that the surface-forming agent gels on the walls to form a layer of defined thickness and (partly) coats the walls. Process further comprises (d) removing from the mould the remaining liquid agent; and (e) charging the mould with a synthetic resin or foam compsn. During the exothermal reactions in the mould, the surface-forming agent which has gelled on the walls is briefly heated and fuses with the synthetic resin or foam. The moulded articles are esp. used in high tension switchgear, esp. those exposed to harmful effects e.g. moisture, heat, sunlight, impact, acids, alkalies or corrosive gases. The surface coating is applied during the prodn. of the moulded article, avoiding a separate step.

Title: Heat-sinking system for loudspeaker or geophone - has heat pipe connecting speaker to heat-sink with low thermal resistance to ambient
Inventor: HECHT GERHARD DIPL ING
IPC: H04R9/02
Filed: 1978-01-20
Abstract: The heatsink system conducts heat away from a dynamic vibrator working on the moving coil principle, e.g. high power loudspeakers, geophones, sonar pulse generators, imbalance exciters, etc. The loudspeaker is connected to one end of at least one heat pipe whose other end (or ends) is connected to a heatsink. The heatsink has a low thermal resistance to the surrounding air. The advantage lies in the system's few components and in its universality, i.e. independence of the shape of the loudspeaker and the housing.

Title: Sealing cap for reverse jet filters - having inverted conical profile which rests in the filter bag opening when jet operates but which opens as filtered air leaves bag
Inventor: BAUR JAN VOM
IPC: B01D46/00
Filed: 1978-02-16
Abstract: On reverse jet gas filters spurious air ingress into the bag during the cleaning operation is prevented by a conical cap. This fits around the venturi throat of the reverse jet. It rests on a lip and seals the top the filter bag. When the air jet operates, the cap is pressed down against the edge of the bag. When the pulse is finished, then the air flow through the bag resumes and the cap lifts to allow the air out. The cap acts rather like a non-return valve. Used on reverse jet gas or air filters. Design prevents the ingress of uncontrolled amts. of sec. air during back flushing without interfering with the main air flow.
