Title: Vegetable slicer for domestic use - in which slicing action prevents food particles sticking to side of mechanism
IPC: B26D1/03
Filed: 1974-07-02
Abstract: Kitchen slicer is basically a cylindrical housing (1), with an operating rotating handle (20). Attached to the handle eccentric to the axis of the container is a bar (18), with tongues acting as carriers (22), for the food to be sliced taking it past knives (11) of U shape and anchored in the container wall arranged above each other meshing between the carriers, (22). At the bottom is a perforated disc (13), with adjustable holes to control size of sliced or chopped food before it falls into container (6). A well sealing lid (23), completes the arrangement to avoid smells as far as possible. The slicer cuts rather than squashes food while the carriers prevent it sticking to the wall.

Title: Central heating pulse control system - includes twin oscillators and counters, with convertor, comparator and gate arrangement
Inventor: TAAG JUERGEN ING
IPC: G05B11/28
Filed: 1977-02-18
Abstract: A control system for central heating has an oscillator which feeds pulses to a binary counter connected to a digital/analog converter, with its output connected to the non inverting input of a comparator. The inverting input of the comparator is connected to a device which supplies a signal corresponding to the temperature of the heat supply. The output of the comparator is fed to a differencing device followed by a flip flop. This is connected to an AND gate then an OR gate supplying a control signal to the heat supply. Also connected to the flip-flop is a limiting branch with a second oscillator, binary counter, differentiator and a negation member. This is also interconnected via a second negation member with the two gates.

Abstract: An exhaust gas heat exchanger has a tank, laminated exhaust gas tubes where the exhaust gas flows, a cooling water inlet pipe and a cooling water outlet pipe. The cooling water flows into the tank and flows through water passages between adjacent exhaust gas tubes and between an inner wall of the tank and an outermost exhaust gas tube. Ribs are formed on the exhaust gas tubes so as to lead the cooling water after colliding with an inner wall toward an upstream side of the exhaust gas tubes to prevent the cooling water from being stuck. Otherwise, spaces between an inner wall of a casing and the exhaust gas tubes are regulated to keep the flow rate of the cooling water in the casing so that the cooling water is prevented from being boiled locally by slow flow rate of the cooling water.
