Patent NL-7403659-A (NL)
IPC: H02K5/22
Filed: 1974-03-19
Abstract: This disclosure pertains to a submersible electric motor having an end bell member at one end and which is suspended from the end of a pipe. The end bell member serves the multiple functions of: closing the end of the motor, suspending the motor from a pipe, supporting a bearing of the motor, connecting liquid passages in the motor to the pipe, and supporting an electricl connection between the windings of the motor and a power cable contained within the pipe. The end bell member may readily be disconnected from the pipe for replacement of the motor while keeping the remainder of the motor intact. Such disassembly automatically breaks the liquid and electrical connections between the respective parts. Further, the end bell member may be disconnected from the remainder of the motor for servicing the motor.

Title: Machine for forming biscuits - using pistons to suck dough from a hopper into recesses in a cylinder
IPC: A21C5/04
Filed: 1974-03-26
Abstract: Biscuit dough is fored by drawing it from a hopper into recesses in the surface of a rotating cylinder using pistons operated by a cam at the centre of the cylinder. The small number of moving parts and simple construction make the machine economically attractive. The pieces of dough are formed continuously and may be dropped one after the other onto a conveyor. As the cylinder rotates a form comes under the dough hopper and the piston moves back drawing a precise quantity of dough and forming it to the desired shape. As it moves out from under the hopper the piston rises until it is level with the cylinder surface. The piece is then removed by a knife or wire and falls onto a conveyor. Preferably the cylinder has four pistons but other numbers would also be possible. Only for dough with the right viscosity. This is includes may types of dough used for biscuits.

Patent NL-7704681-A (NL)
IPC: G04C21/38
Filed: 1977-04-28
Abstract: In apparatus for generating an alarm sound especially for small watches, all functions of the alarm are controlled by integrated circuitry which detects the state of a common connection point between a manually operable switch and a reference switch which is opened and closed by the timekeeping mechanism. There is thus only one external terminal led out from the integrated circuit for the purpose of connecting to the output side of the reference switch and the manually operable switch. The reduction in the number of terminals permits a corresponding reduction in the number of pins required and a reduction in the size of the circuit. The integrated control circuit includes flip-flops, gate circuits, inverters and a five minute counter.
