Title: Compensation for wow and flutter on FM recordings - involves arrangement of filters and operational amplifiers
Inventor: GROSS THOMAS ALFRED OTTO
IPC: G11B20/22
Filed: 1974-06-11
Abstract: The apparatus is applicable to many different media and the compensating network modifies the information read from the recording. This is of a frequency modulated form and the compensating network operates to equalize the sidebands and so to remove the effects of wow and flutter. The network consists of an amplifier, a high pass filter and a modulator. An output is produced from this and fed to a low pass filter, the output of which is modulated by the original tape output filtered at any low frequencies (up to 100 Hz). The output of this is modulated once more and transduced to the form required to give the compensation needed.

Title: Pneumatic handbrake for lorry and trailer - with one of three settings unstable to only brake the lorry
IPC: B60T15/04
Filed: 1974-07-24
Abstract: The brake control valve has two stable settings and one unstable one. The first setting connects the spring loaded hold off brakes on the lorry to the pneumatic supply while the trailer remains fully unbraked. The second setting of the hand operated valve vents the lorry brakes and connects the trailer brakes to the brake servo line for emergency braking. A third setting only vents the lorry brakes, and is used for parking, after which the mechanical setting is unstable and the valve returns to the second setting. This satisfies parking regulations which require a mechanical parking brake when the vehicle is left unattended.

Title: Logic circuit having a discrete memory cell - has FET'S to provide control and store between read, write and reference lines
Inventor: JULLIEN JEAN-CLAUDE
IPC: G11C11/40
Filed: 1974-12-27
Abstract: The discrete memory cell for binary logic operations, intended to overcome the deterioration of stored data due to time related effects without increasing the number of components as in bistable circuits where there is a power consumption penalty. Storage is based on the gated 'ON' and 'OFF' states of a field effect transistor controlled by a second transistor whose source and drain are connected to the source and gate of the first. The cell is connected across the read/write to reference line grid via a switch which itself may be an FET to the gate/drain junction. Similarly, drain and source resistors of the control transistor may themselves be FET's.
Patent FR-2265476-A1 (FR)
Title: Press. lifting device vert. control appts. - uses differential gear to vary effective radius of crank
IPC: B21D43/10
Filed: 1975-01-03
Abstract: The apparatus adjusts the vertical movement of lifting machinery used to transfer workpieces on and off presses and similar machines. Vertical movement is caused by a connecting rod pivoted on a crank. This crank can be moved by rotating a screw in a nut, so varying the effective radius of the crank. Control is effected by an input shaft driven by an impulse type motor. Under normal circumstances a control shaft rotates at the same speed as a main drive shaft and the screw does not rotate within the nut. When so wished, the input shaft activates a differential gear system and bevel gears rotate the screw, altering the effective crank radius.

Title: Alternator and exciter set - has exciter mounted on and inside the rotor of the alternator
Inventor: FAGEL ROGER
IPC: H02K19/38
Filed: 1975-11-14
Abstract: The shaft of this combined alternator and exciter set has the rotor and rectifiers of the exciter set mounted directly on to it.
