Patent DE-2349180-A1 (DE)
Title: Ridged road-surface-finishing roller - with peripheral seam beadings parallel or at angle to axis on sheathing band
IPC: E01C19/43
Filed: 1973-09-29
Abstract: The roller is used for creating a road surface which is not perfectly smooth, but slightly grooved to reduce the danger of aquaplaning in wet weather, to improve tyre grip on the surface, and to combine this with improved drainage. The beadings on the roller sheath may also be peripheral rings running round it, and these may be slightly serrated in profile. In multisheathed rollers one or more sheaths may be so fitted, and there may be more than one, running synchronously to each other. The roller itself may be of the static or of the vibrating type. The process is inexpensive, with minimal wear on the ridge-making fittings, which can be promptly applied to a road surface that is still soft, and when they are worn they can be renewed. is also consolidated at the same time, with processes on site reduced and less traffic delay.

Title: Loosened silage discharge machine - has vertical outlet pipe with walls of meshwork allowing air passage only
Inventor: SCHAUMEIER ERWIN
IPC: A01F25/20
Filed: 1973-11-06
Abstract: The machine discharges to a point alongside the silo, by means of a blower delivering via a pipe with a vertical section ending above the point concerned. The vertical section has walls in the form of a sieve, allowing the passage of air but not of silage, and it can be in the form of a flexible hose of coarse-mesh textile or similar material, or plastic fibre, with its lower end able to be turned inside out, and held in this position by clips. Alternatively, the pipe can be of woven wire, or perforated sheet metal. Where the blower is mounted on a cutter resting on top of the silage and loosening it, the discharge pipe can comprise a radial run from the blower, passing through a hatch in the silo side and of closed construction, joining onto the vertical hose.

Title: Safety valve for continuous flow electric water heater - is operated by thermostat on cold feed to heater
Inventor: RICHTER HANS HERBERT
IPC: F24H9/20
Filed: 1973-12-03
Abstract: A continuous type electric water heater for domestic use has a heater body with a cold water feed and a tap controlled hot water discharge. The heater element is controlled by a flow switch in the water flow. A safety cut off is worked by a pressure switch since a non-return valve in the cold feed ensures that the pressure must rise if the heating element is on without flow through the heater. In case the non-return valve lets by, a further cut is provided by a thermostat clamped to the cold feed near the inlet to the heater and this operates a relay which opens a contactor in the electric supply to the heater element.

Title: Funnel drain connection element for concrete roofs - has adhesion flange merging into pipe stub
Inventor: BEINLICH HORST
IPC: E04D13/04
Filed: 1974-02-02
Abstract: Funnel element is connected to a shaped piece insertable in a concrete roof or floor and with a trapezoidal external shape for self-supporting seating in the roof, and with an inner opening as an exactly fitting, heat-insulated roof perforation for the connection of water drainpipes, or sanitary downpipes; the funnel element has an adhesion flange which merges into a pipe stub which, when the funnel is used as an entry element, engages from the upper side of the roof into a fall pipe or fitted pipe piece seated in the shaped piece, secure against backwash; in the case of use of the funnel element as a connecting sleeve, it faces upward.

Title: Tape recorder for synchronising to cine camera and to projector - has resettable two-way counter and three stage control circuitry
IPC: G03B31/04
Filed: 1974-03-29
Abstract: The tape recorder has inputs for leads coming from a cine camera and from a projector to feed film transport signals into one stage of the control circuits. A scanner reads optical or magnetic markings on the tape and feeds the resultant signals into a second stage of the circuits.

Title: Quality control system for cigarette making machine - has strand density, length and weight signals combined to indicate substandard product
Inventor: WAHLE GUENTER
IPC: A24C5/34
Filed: 1974-10-12
Abstract: Tobacco formed into a continuous strand is deposited onto a continuous paper strip which is gummed, folded around it and sealed. A weighing device is positioned after the knife which cuts the wrapped strand into cigarette lengths. When a button is pressed, a test pulse is emitted to an AND gate to actuate a valve to blow a determined number cigarettes into the weighing pan, and another AND gate operates a counter. Signals are also obtained from a strand density monitor employing beta rays from a Strontium 90 source, which pass into an evaluator with a pair of equalising arms followed by threshold value transmitters on an OR gate, flip flop, NOT gate, a shift register arrangement. These signals are combined with signals from the weighing system potentiometer.

Title: Parking arrangement for two stacked motor vehicles - has upper platform actuated by hydraulic system with telescopic pivoted levers
Inventor: KUIPERS HEINRICH
IPC: E04H6/06
Filed: 1974-11-23
Abstract: The parking arrangement is used for parking of two vehicles on top of each other. The upper parking platform is moved into the parking position by a lever arrangement. The platform actuating arrangement has a minimum number of moving parts reducing the risk of injury to people in the vicinity. This arrangement is highly compact and the upper plateform is not placed fully on the ground for saving space and it remains inclined partly over the lower vehicle in lowermost position. The top platform (5) is actuated by a lever arrangement held on horizontal members. The actuating members are pivoted on the ground and they come in turn into contact with stopping elements with the result that the upper end carries out movement whose path follows connected curved paths.

Title: Linear conductor for radio wave radiation - is laid along a track divided into a number of sections
Inventor: TREEN KENNETH FREDERICK
IPC: H04B5/00
Filed: 1975-01-11
Abstract: A transmitter is provided for each section. The transmitter at the track beginning receives the signal to be transmitted, modulates with it a carrier frequency and retransmits it through a coaxial cable to the following transmitters. Each multiplies the modulated signal frequency and applies it to a linear conductor of a certain length for its radiation. The modulated signal may be passed on to the next transmitter through high and low-pass filters and the linear conductors. Adjacent linear conductors are interconnected by non-radiating junction lines, and the filters separate the modulated signal from sender outputs.
