Title: Thermally-responsive starting device for a single-phase asynchronous motor
IPC: H02K17/30
Filed: 1967-08-25
Abstract: A bimetal starting switch for a single phase asynchronous motor is opened by a first heater 7 of high thermal capacity, the heat stored therein being sufficient to keep the switch open until a second heater 9, shunting the contacts, heats up to maintain the contacts open for the remainder of the time that the motor is energized. The first heater 7, of carbon or silicon carbide, is in series with the bimetal 10 and the resistive type start winding 1 of the motor and preferably its resistance is 50% of the total. The second heater 9 preferably has a high positive temperature coefficient it remains in series with the winding 3 but reduces the current to a negligible value. As shown, the heater 9 is annular, and the bimetal strip 10 is attached to it by a rivet 11. In an alternative arrangement (Fig. 2, not shown), the first heater is placed between two bimetal strips, each of which carries one of the contacts, and this heater is not part of the shunt path of the second heater.

Title: Data transmission over pulse code modulation channels
IPC: H04J3/10
Filed: 1971-02-17
Abstract: An arrangement to substitute data bits for and extract these data bits from at least one channel of a PCM-TDM intelligence (voice) communication system. The data bits do not have to be synchronized with the normal PCM bit stream. The normal PCM bit stream employs n bit positions, one bit position being employed for signalling and/or synchronization and (n-1) bit positions being employed for conveying intelligence. Data bits equal to or less than (n-2) are substituted for intelligence in a selected PCM channel. The data bits are grouped at one end of the (n-1) bit positions and a marker bit is inserted into a bit position adjacent the last data bit. The location of the marker bit in the (n-1) bit positions indicates the number and repetition rate of the data bits. The position of the marker bit within the (n-1) bit positions is employed in the receiver to extract the data bits from the PCM bit stream and to return the data bits to their original repetition rate for further utilization.

Patent ES-416248-A1 (ES)
Title: Anti-locking braking device
IPC: B60T8/34
Filed: 1973-06-25
Abstract: An anti-locking braking device for a wheel of a motor vehicle for reducing jerky braking, wherein a fluid operated brake cylinder is connectable, when the wheel is about to lock, to a fluid outlet comprising first and second flow paths leading to a reservoir. In the first flow path a restriction is provided downstream of a first chamber whose volume is increased by movement therein of a spring biased first piston under the effect of pressure of the fluid admitted to the chamber. Such movement is arranged to open a first valve in the second flow path, and fluid form the brake cylinder to the reservoir can by-pass the restriction and thus a faster rate of pressure drop in the brake cylinder can be achieved, provided a second valve, also in the second flow path is open. Movement of this second piston controls opening and closing of the second flow path by the second valve which is open when fluid pressure in the first flow path upstream of the restriction exerts a lower force on one side of the second piston than the force exerted on the other side by a spring.
