Title: Insulated carrying case for containers of heated food - has refillable cavities for hot fluid in side walls closed by lid
IPC: A47J41/00
Filed: 1975-02-07
Abstract: The side walls of the carrying case or container which are connected to the base (3) are provided with cavities which are designed to be filled and refilled with hot fluid and can be closed on the outside by attaching a lid. The side walls are preferably jacketed to provide the cavities so that the parallel spaced wall members form a slit-like filler opening for the fluid in the plane (9) of the lid, wherein the latter has a sealing strip on the underneath, which fits into the opening when the lid is closed. In this way when the hot fluid cools down it can be replaced so that the food can be kept hot for longer periods. The case is preferably made of foamed plastics, such as polystyrene, which is air and water tight to provide good insulation.

Title: Farrowing crate with angled rear end walls - is provided with vertical gap between opposite angled wall parts
Inventor: ULRICH FRIEDRICH
IPC: A01K1/02
Filed: 1975-04-15
Abstract: The rear end portion of the farrowing cage longitudinal side walls are bent at a given angle. When the crate is closed a vertical gap (13) is formed between the opposite end portions (10) of the longitudinal side walls (6,7), the gap being adjustable by displacement of the walls. Preferably the adjustment is carried out by means of a displaceable connecting stirrup (8) which holds the longitudinal walls, when the crate is closed. Thus the displacement of the longitudinal walls permits matching of the crate size to the sow dimensions.

Title: Wax pattern for investment casting of tooth crowns - with runner on inside after withdrawal from mould
Inventor: VIVANI GUISEPPE
IPC: B22C7/02
Filed: 1976-05-10
Abstract: Wax pattern for investment casting of tooth crowns has the runner located on the inside, i.e. the hollow side, after withdrawal from the mould of the solidified pattern.

Title: Electronic fuel consumption meter for vehicles - displays consumption per distance unit using flowmeter and tachometer signals
Inventor: SIERADZKI FRANZ
IPC: G01F9/02
Filed: 1976-08-03
Abstract: The fuel consumption meter for motor vehicles consists of a fuel flowmeter of the impeller type giving a pulsed output signal which is passed through a low-pass filter to produce a DC signal proportional to the flow rate. The voltage is converted into a current and fed to a capacitor. A tachometer with frequency of its AC output signal proportional to the speed of the vehicle, is connected to a trigger. The pulses are differentiated and the positive spikes control a switch which, in turn, discharges the capacitor. A saw-tooth waveform is produced at the capacitor whose peak amplitude is proportional to the instantaneous fuel consumption per unit distance covered by the vehicle.

Title: Swinging agitator with moving flaps - so that to-and-fro motion results in liquid motion in only one direction, esp. for use in crystallisers
Inventor: SEIFERT DIETER DIPL ING
IPC: B01F11/00
Filed: 1976-09-09
Abstract: Process for producing recirculating flow in a vessel uses a to-and-fro motion in the agitator element. This is capable of changing its form, depending on the direction in which it is moving, so that its resistance to flow drops sharply in one direction. To this end it is equipped with one or more flaps so that on the return action, these open with the liquid flow. They can be made from an elastic material or have a flexible connection to the carrier arm, so that an elastic member acts as hinge to the flap. The vessel shape is designed to suit the motion of the stirrer or vice versa. Esp. for use in crystallisers where a relatively gentle action is necessary to prevent excessive nucleation, and also in some biological processes where too vigorous action can be damaging.

Title: Optical sensing system above roulette table - automatically records all winning numbers by coded signals derived from reflection from balls in end position
IPC: A63F9/00
Filed: 1976-12-10
Abstract: An optical sensor is used to locate the ball on a roulette table after it comes to rest in a numbered pocket (2), and is placed in a hidden position above the table. The sensor produces a signal which is coded so that each pocket number can be identified. A printer which is linked to the sensor processor then produces a continuous recording of all winning numbers that appear over any length of time. This automatic method can replace the time consuming and often unreliable manual recording.

Title: Computerised tomographic X=ray machine - uses data processing system to convert zigzag matrix paths into straight line paths
Inventor: LEMAY CHRISTOPHER ARCHIBALD GO
IPC: A61B6/03
Filed: 1977-02-28
Abstract: A computerised tomographic x-ray machine which rotates a funnel shaped beam of x-rays around a section of the body of a patient, with a detector under the camera, with the patient's body between them. This is connected to an amplifier, and integrator, an analog-digital converter and a logarithmic converter. This is followed by a calculator, an interpolator, and an address selector which also receives signals from two photo cells and a matrix memory.
