Title: Side-loading forklift truck - has two steered wheels each with its separate steering mechanism
IPC: B66F9/06
Filed: 1979-10-17
Abstract: The side-loading forklift truck is particularly for working in four directions, the chassis being preferably U-shaped, with forks extensible to the side. The driver's cab and auxiliary machinery are mounted on the side away from the forks, together with two steered wheels. Each of these steered wheels (1,2) has a separate steering mechanism (3,4). There can be a separate steering control (5) in the cab(6) for each of them, or alternatively a single one, to which the mechanisms can be coupled as desired. The coupling mechanism can work with a travel direction selector switch, so that the foremost wheel in the travel direction is coupled to the steering control.

Patent DE-3006090-A1 (DE)
Title: Security circuit for fruit machine - uses logic gates to determine whether stop signal coincides with actual stopping of rotating wheels
Inventor: PRUEMM GEORG
IPC: G07F17/34
Filed: 1980-02-19
Abstract: An electronic circuit monitors each wheel of the machine and ensures that the stop signal coincides with the actual stopping of the wheels. The rotating wheel generates pulses via a proximity switch. These pulses are integrated by a monostable resulting in a continuous signal whilst the wheel is moving. This signal, together with the stop signal derived from a switch is fed to an AND-gate. Coincidence of the stop signal and the actual stopping of the wheel sets a timing device. The output of this, together with that of similar devices linked with the other two wheels is ANDed and results in a signal which initiates payment. Additionally, an exclusive OR-gate may be employed to determine whether rotation continues after the stop signal.

Patent DE-3030758-A1 (DE)
Inventor: LANGENEGGER GEORGE ING GRAD
IPC: A01K7/02
Filed: 1980-08-14
Abstract: For controlling the rate of supply of water to a watering bowl, a diaphragm valve with a diaphragm is placed in the water connection system, one side of the diaphragm resting against a barrel-like part, the space within the barrel being joined up, for example, with the bowl while the space round the barrel on the same side of the diaphragm is joined up with the water inlet so that, when the diaphragm is moved clear of the end of the barrel, water may make its way from the inlet into the bowl. On the opposite side of the valve diaphragm there is a pilot control space into which water may make its way through a small hole in the diaphragm and out of the pilot control space into the bowl through a pilot valve system in the form of an opening and a moving pilot valve which is worked by a lever or the like in the bowl, by a float or by a pilot diaphragm acted upon by the liquid level in the bowl. When the pilot valve is shut, water will slowly make its way into the pilot control space so that the pressure therein goes up to the pressure of water let into the space on the other side of the diaphragm with the outcome that the diaphragm is sealingly pressed against the end of the barrel. If the pilot valve is moved clear of the pilot outlet, the head of water in the pilot control space at once goes down to the pressure in the bowl so that the valve diaphragm is moved clear of the end of the barrel and a large valve opening produced so that the bowl is quickly filled up even with a low water input head, while the force needed for working the pilot valve is small, even if the head of the input water is at a high value.

Title: Coin tester with trajectories branching into different planes - has swivelling sliding sensor on rule with fixed stop
Inventor: BARTH WALTER ING GRAD
IPC: G07D5/10

Abstract: A coin testing device separates coins with smooth and knurled edges. It contains a coin sensor consisting of a tilting and axially movable body (3) forming a two-armed lever with a tongue projecting at an angle against the coin movement direction so as to be raised and tilted by the coins. The device enables the coins to be sorted and directed into trajectories which are not in the same plane. This is achieved using a body (3) mounted on a movable dia. test rule (2) placed parallel to the path (1) along which the coins pass. The stop (4) against which the body can come to rest when displaced is attached to the wall of the coin path so as to project through an aperture (5) in the rule (2).
