Title: Corrosion resistant steel - by depositing chromium nickel,cobalt or molybdenum alloy with iron,and diffusing under hydro
Inventor: LEROY VINCENT
IPC: C23C10/28
Filed: 1974-01-22
Abstract: Steel pdt. with a non-oxidisable coating is produced by depositing and diffusing >=1 of the elements Cr, Ni, Co, Mo, or an alloy of these elements, pref. with Fe, on a mild steel substrate, using the usual phases of cleaning, deposition, thermal treatment, and opt. rolling and recrystallisation. The thermal treatment at a high temp. is effected by (a) prediffusing under a dry H2 atmosphere, (b) decarbonising under a decarbonising atmosphere, and (c) diffusing under a dry H2 atmosphere. Stage (a) is effected at 700-1300 pref. 1000-1250 degrees C for 0.25-16 hrs., stage (b) at 900-1300 degrees C for 0.25-4 hrs., and stage (c) at 1000-1300 degrees C for 10-48 hrs. High resistance to corrosion in aqs. media is obtained, even when the substrate is an ordinary steel.

Title: Hatch cover for ship - with pressure blocks near hatch sill to take cover weight load
Inventor: KLOESS PETER DIPL ING
IPC: B63B19/14
Filed: 1974-06-27

Title: Mixing of fluids in fixed proportions - using solenoid valves energised in turn by electric timers
Inventor: PHILPOT JAMES EDWARD
IPC: G05D11/02
Filed: 1974-07-11
Abstract: In a system for producing a mixture of different fluids in known fixed proportions, a small quantity of each fluid is allowed to flow in turn into a mixing vessel at a known flow rate. When all of the component liquids have been introduced the cycle is repeated until the mixture reaches a preset level, at which point the cycle in progress is allowed to continue to completion. The mixture is then drawn off as required until a small fall in level in the mixing vessel is achieved, when the draw-off pump is stopped and the component liquids are again introduced. Particularly for producing 'Rubber and Etch' solutions for printing presses.

Title: Non-drip sausage-cooking accessory for grills - comprises rotary cages interconnected for even rotating cooking without disadvantageous burning of fat
Inventor: TWIEHOFF KARL-HEINZ
IPC: A47J37/04
Filed: 1974-10-12

The cages are mounted evenly divided about the axis of rotation so that each sausage is exposed to approximately the same intensity of heat during rotation. Potatoes or similar food items can also be cooked in these cages since the constant rotation ensures even cooking. Each cage can be provided on its end side with a retaining ring, these rings being connected together by rods (15). This cage system can also be used with all other types of grills.
Patent DE-2453562-A1 (DE)
Title: Viscous coupling for driving engine cooling fan - compensates viscosity reduction due to temp with expanding plastic ring
Inventor: MUELLER KARL
IPC: F16D43/25
Filed: 1974-11-12
Abstract: The drive to the fan is transmitted from the hub through the viscous oil film on the surfaces between the discs and the oil filled housing. A coned spring normally keeps the discs in contact with the housing but as speed increases the pressure of the oil film increases, overcoming the force of the disc spring. A split plastic ring of trapezoidal cross section is held between the chamfered outer edges of the discs. As the discs are forced together the ring is expanded and the drive is then transmitted through the oil film on its outer surface. The ring also expands with increasing temperature and so compensates for the reduction of oil viscosity.

Title: Cutting laminates from mineral wool slabs - continuous process has vertical revolving cutters
Inventor: IHLEFELD KARL-HELMUT
IPC: D04H1/4209
Filed: 1975-01-13
Abstract: Device for the lamination of mineral fibre slabs consists of a knife shaft with circular blades, dividing discs or saws or similar, whereby the distance between the dividing units determines the thickness of the strips, thereby distinguishes in that the knife shaft is arranged vertically. The mineral fibre slabs are also fed vertically and the resulting strips after cutting are fanned out from each other by suitable guides. From there they are guided by equalizing vertical guides together to a level running plate by which the fibre direction is basically vertical to the surface.
Patent DE-2507330-A1 (DE)
Title: Generation of electrical power using sea wave action - involves converging channel and wave chamber displacing air to drive turbine
Inventor: RICAFRANCA ROMULO M DR
IPC: F03B13/14
Filed: 1975-02-20
Abstract: Sea waves are amplified in a converging channel that leads to an opening in a cylindrical pressure chamber. The pressure chamber has a conical top section leading to a housing containing an air turbine and generator. Sea wave motion produces standing waves of considerable energy within the pressure chamber. The standing wave motion results in pulsating air flow across the turbine. Vent apertures in the top side of the turbine housing permit the necessary air flow to occur. Guide blades combine with the runner wheel to allow air expansion to occur so as to produce rotational motion of the generator driveshaft.

Patent DE-2545619-A1 (DE)
Title: Transmission clutch for road vehicles - has springs with oval coils to allow reduced dia. or axial length
Inventor: STEEG KLAUS
IPC: F16F15/123
Filed: 1975-10-11
Abstract: The drive from the vehicle engine is transmitted through friction linings to the clutch plate and then through a damping spring to plates and a hub. The damping springs must be sufficiently strong to transmit the engine torque and as a result are relatively large. By making the spring coils oval with the major axis horizontal, the dia. of the clutch can be considerably reduced without reducing the torque transmission capability of the spring. Where the axial dimensions of the clutch are restricted, the springs can be arranged with the major axis of the oval coil lying along a radius of the clutch plate.

Title: Digitally coded LF radio remote control for garage door - modulates digital signal onto carrier wave for comparison at receiver
Inventor: SANDMANN ERNST ING GRAD
IPC: G08C19/28
Filed: 1976-01-13
Abstract: The digitally coded LF radio remote control, for garage doors etc, modulates the coded information onto a sinusoidal carrier wave when a reset pulse is released . A comparator at the receiver compares the received code with a reference and only releases the switching pulse when the two agree. Either the CW signal or the first bit in the information sequence may be used as reset signal. This arrangement enables a carrier to be used in any required frequency range. Relatively broadband transmitter and receiver permit coding to be chosen as required.

Title: Cellulose fibre webs for surfacing of plywood, chipboard, etc. - impregnated wet with urea- or melamine-formaldehyde precondensate
Inventor: ETTINGSHAUSEN OTHMAR VON DIPL
IPC: D04H1/587
Filed: 1976-02-04
Abstract: Surface finishing of flat surfaces employs a continuous web of cellulose fibres. The web is subjected in known manner to an alkali treatment with subsequent neutralisation. The web, without intermediate drying and immediately following neutralisation, is impregnated with a urea-CH2O or melamine-CH2O precondensate. The concn. used is such that, after drying, 25-100 wt. % of precondensate is applied. In an example, a 100% viscose web of 100 g/m2 was impregnated with a 25% solids soln. of 50% commercial urea-CH2O precondensate to a pick-up of 77.2%. The web was laminated to chipboard at a press. of 20 kp/cm2 for 10 min. at 140 degrees C and provided excellent adhesion to lacquer films.
