Filed: 1968-09-13
Abstract: 1,202,803. Knitting-machines. FRANZ MORAT G.m.b.H. 13 Sept., 1968 [26 Sept., 1967], No. 43625/68. Heading D1C. Yarn is fed to the needles of a circular machine from a bobbin 2 by guiding it over a series of rollers at the positions where it changes direction. After leaving the bobbin an eye 4 regulates the ballooning effect whereafter it is fed over the rollers 6, 7 of a stop motion device the rollers pivoting downwardly in the event of excess tension. Following the stop motion the yarn passes round a roller 9 which is influenced by a spring to restrict the movement of the roller whereby the roller acts as a brake on the yarn. A yarn feeding device 15 around which the yarn is wound advances the yarn to a further stop motion 16 consisting of rollers 17, 18, 19 which bear on and detect the yarn. A further roller guide 20 directs the yarn to the knitting station but to regulate the tension in the yarn a tensioning arm 22 having a guide 23 engaging the yarn is provided. The arm 22 is connected to a spring 21 capable of adjustment.

Title: Braking system for automotive vehicles
Inventor: FRISHAUF STEPHEN HERMAN
IPC: B60T13/16
Filed: 1966-10-04
Abstract: 1,147,995. Fluid-pressure brakes. S. H. FRISHAUF. 4 Oct., 1966 [23 Oct., 1965], No. 44186/66. Heading F2F. In a braking system of a front wheel drive vehicle, brakes 16a, 16b provided on the rear wheels 15a, 15b are applied, independently of any other brake applying means, by a valve 36 which controls the supply of hydraulic fluid from a pump P driven by the engine 1, the valve 36 being controlled by a signal from a device 10 which senses whether the front wheels 14a, 14b are in the driven or overrun condition and, in the latter event, causes the valve 36 to supply fluid from the pump P to the brakes 16a, 16b to reduce or eliminate the tendency for the vehicle to slew about its front wheels in this condition. The embodiment shown includes a one-way clutch 30, so that the braking of the rear wheels replaces engine braking on the overrun, the device 10 comprising rotating magnets 31 on driven shaft 11 which co-operate with coils 32 carried by driving shaft 3 to give an electrical signal at 33 when the speed of shaft 11 exceeds that of shaft 3 owing to free-wheeling of the clutch 30 on the overrun. The electrical signal energizes, either directly or via an amplifier, a winding of the valve 36 to cause fluid to be supplied to a line 18 which feeds the cylinders 16a, 16b. A master cylinder 19, e.g. one of two for supplying fluid independently to front and rear wheel brakes (the former not being shown) also communicates with the line 18, a check valve 37 preventing reverse flow to the pump in normal brake operation. The clutch 30 is arranged to be locked through an operating cable 21 when the gear lever 20 is moved into reverse. In an alternative embodiment (Fig. 2, not shown) the one-way clutch is omitted and the drive to the front wheels includes a worm or other drive gear which can be arranged, e.g. by sensing axial movement of the worm, to indicate the direction in which torque is being transmitted between the engine and front wheels, and to control directly the position of a valve plunger controlling the supply of fluid from the pump 34.
