Abstract: 1369522 Fasteners H K PORTER CO Inc 6 Nov 1972 [9 Nov 1971] 50977/72 Heading E2B A fastener 2 includes a substantially plane peripheral portion 7 and extending inwardly therefrom a plurality of angularly spaced tongues 10 defining a bore 5 and extending at an angle e.g. 45 to the plane of the peripheral portion 7. Recesses 6 are defined by the inwardly extending sides 9 of the tongues 10 and portions 8 of the peripheral portion 7, the recesses being greater in area than the tongues 10 and being of a shape such that a tongue if it could be placed therein and would be encompassed thereby. Means including parts which, could they be superimposed, would be complementary are also provided, these parts being equally spaced from the axis of the bore 5 and angularly spaced apart about the axis. As shown these parts comprise an ear member 13 and a recess 16. The arrangement is that normally at least two of the fasteners are used together on a rod, and when two fasteners are used the complementary parts interfit so that the tongues 10 of one fastener fall within the recesses of the other fastener. If the fastener is to be used for securing a corrugated roofing sheet 21 to a beam 21 a sealing member 25 is positioned between the fastener and sheet. The member 25 has a bore for reception of a rod 23 part of which bore is frusto conical and part right cylindrical (Fig. 8, not shown). Two sets of fasteners may be applied to the ends of a rod to fasten together two sheets (Fig. 6, not shown) through which the rod extends.

The cylinders may be fastened to or formed in e.g. by boring the bridges. The cylinders 206 for driving the worm 11 may be formed in the bridge 8 for supporting the cylinder 12 and the cylinders 208 for driving the unit may be formed in the bridge 9 for supporting the worm 11. Alternatively, the positions of the cylinders may be swapped (see Fig. 2). The modified arrangement allows shorter sleeves 23 than in the parent Specification and enables greater injection pressure since all the cylinders can be employed when coupled by line 127. The unit may be supplied with a continuously open nozzle or a locked nozzle.

Title: Improvements in or relating to Hydrostatic Steering Devices, Particularly for Motor Vehicles
IPC: B62D5/093
Filed: 1967-11-15
Abstract: 1,198,830. Hydrostatic steering devices. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. 15 Nov., 1967 [18 Nov., 1966], No. 52017/67. Heading B7H. A hydrostatic steering device for motor vehicles comprises a control pump 1 connected via pipes 5 and 6, a control valve 2, and pipes 7 and 8 to a servomotor 3 controlling the steered wheels of a vehicle, wherein by-pass non-return valves 23 and 24 and pipes 9, 9<SP>1</SP> and 10, 10<SP>1</SP> (or conduits in the casing 12 of the control valve 2) connect the pipes 5, 6 to the pipes 7, 8. An equalizing tank 4 is provided to compensate for oil leakage and the differing areas of the two faces of the piston of the servomotor 3. In the neutral position (as shown) of the valve member 13 of the valve 2, the pipes 5 and 6 are connected via ducts 14, 16 and 19 and 15, 18 and 20 to the pipes 7 and 8. On rotation of the wheel S an excess pressure is created, e.g. in the pipe 5, which is transmitted to the servomotor 3 as before, but also to the valve end chamber via the bore 14<SP>1</SP> thus moving the valve member 13 to the right of Fig. 1 so causing oil from the right-hand chamber of the servomotor 3 to flow back to the pump 1 by way of valve 24, and allowing compensating oil to flow from the tank 4 via ducts 11, 17 and 18 to the pipe 8. A pressure shock transmitted from the steered wheels to e.g. the left-hand chamber of the servomotor 3 while the valve member 13 is in its neutral position, displaces the valve member 13 to the right and causes the valve 24 to close so that the shock is not transmitted to the steering wheel. If the valve member 13 sticks, opposite rotation of the steering wheel S supplies fluid to assist the spring 22. The system still functions when one of the valves 23, 24 fails to close, provided the valve member 13 is free to move. The valves 23, 24 may be incorporated in the control valve casing 12.

Specified organic solvents include dimethyl formamide, dimethyl acetamide and dimethyl sulphoxide. Examples are given in which the spinning solution is spun by a dry spinning method to form the dyed filaments.

Abstract: 1,193,318. Colour television synchronization. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 23 Nov., 1967 [3 Dec., 1966], No. 53388/67. Heading H4F. The invention is concerned with the synchronization of the phase of operation of a linefrequency switch 9, Fig. 3, used in a receiver of the SECAM (Registered Trade Mark) colour television system in which two colour signals are transmitted line-sequentially by frequency modulation of a carrier wave whose resting frequency is changed from line to line between two values. In accordance with the invention bursts of carrier signal, curve b Fig. 1, at the resting frequencies which occur during the blanking interval are separated from the received signal, curve a, by a gate 3 and applied to a frequency dependent circuit 10 to derive a voltage, curve g, from which a sinusoidal voltage, curve c, of half line frequency is filtered by a circuit 11. This voltage is then employed to synchronize a multivibrator 8 which drives the switch 9. As illustrated, circuit 10 is a frequency discriminator and circuit 11 comprises an oscillator. In an alternative arrangement, Fig. 2 (not shown), circuit 10 is replaced by the combination of a resonant circuit tuned to one of the resting frequencies and an amplitude detector, whilst circuit 11 is replaced by a resonant circuit. Reference is also made to the use for the frequency dependent circuit of a quartz filter which selects from the frequency spectrum of the carrier bursts two oscillations differing from each other by half line frequency, the oscillations being mixed to obtain the difference frequency. The arrangement shown in Fig. 3 may be operated alternatively with signals of the PAL colour television system where the carrier bursts during the blanking intervals have the same frequency from line to line but are changed in phase between two values differing by 90 degrees. Switch 12 is operated to the alternative position and connects the output of an oscillator 14, which operates at carrier frequency, to circuit 10, whereby the circuit functions as a phase discriminator Oscillator 14 is synchronized by the bursts of carrier signal by means of a variable reactance circuit 16 controlled by a voltage obtained from the output of circuit 10 via a CR network 15 having a time constant very much greater than the period of a line.
