Abstract: 1,038,614. Valves. H. J. SHAFER. Feb. 19, 1963, No. 6624/63. Heading F2V. A valve member 14, Fig. 1, has an aperture therethrough for the passage of fluid and a groove 40A in its outer surface to receive a sealing member 39A of resilient material which prevents fluid flowing between the valve member and its seating surface 34 when the valve member is in the closed position. In the preferred embodiment, two rings, each of smaller circumferential length than its groove, are provided and are held in place either by a retainer ring 42 and a snap ring 44 or by a plate 45 secured by a set screw 46 to the valve member. Pins 27 key the latter to a stem 13 rotated by an hydraulic motor secured to a mounting flange 12. Flow connections 15A, 15B are welded at 16A, 16B to a cylindrical portion 10 of the body and washers 14A, 14B of the material known by Registered Trade Mark " Teflon " are provided above and below the valve member. In Fig. 3, the stem 113 is journalled in a sleeve 113<SP>1</SP> of " Teflon " and has a vent 125<SP>1</SP> to prevent fluid from being trapped during assembly while the sealing members are held in place by rings 143B of " Teflon " and plates 142.

Title: Coil arrangement for relay
IPC: H04N19/593
Filed: 1974-02-15
Abstract: 1457556 Television INTERNATIONAL STANDARD ELECTRIC CORP 15 Feb 1974 [26 Feb 1973] 6945/74 Heading H4F In a differential pulse code modulation system for the transmission of picture information, if the difference between two compared signal sample values exceeds a predetermined magnitude then the difference between the present sample value and a value predicted (i.e. interpolated) from previous sample values is transmitted, this difference signal being added to a similarly predicted value at a receiver in response to a flag bit transmitted with the location and difference amplitude value bits forming the DPCM signal. In a standard DPCM transmitter, sample values of the video signal delayed by one sampling period by delay V1 are subtracted (Diff) from the input sample values, the differences being quantized (Qu), encoded (Cod), and combined with sync. code words generated G from separated (Au) sync. pulses in a transmitting circuit (Sk). As shown the output from delay V1 is fed back to adder (Su1) in the conventional manner. According to the invention if the difference output from quantizer (Qu) exceeds a predetermined magnitude as determined by a threshold circuit SW a gate circuit T is enabled to pass the sample output from adder Su1 and sample position information (from a counter Za) to a circuit VA which compares this sample magnitude information with corresponding sample information from the previous line (or picture) stored in store Sp. This sample information is then stored in the store Sp together with predicted sample information and associated flag bit for use in the next line (or picture). A location comparator circuit VP continuously compares the sample position information signal from counter Za with those stored in store Sp corresponding to predicted samples and when they agree a circuit St is actuated to switch contact u to pass the predicted sample value to the subtractor (Diff). A receiver is described with reference to Fig. 2 (not shown) in which the subtractor is replaced by an adder.

Abstract: 523,134. Photographic shutters. KODAK, Ltd. March 3, 1939, No. 6980. Convention date, March 4, 1938. [Class 98 (i)] Means for preventing rebound of the blades of a shutter of the type having a setting lever for tensioning the master member and symmetrically pivoted shutter blades which are opened and closed by oscillating a blade ring, comprises a spring latch which restrains the operating lever of the master member at the end of the exposure. The shutter blade ring 9 has a pin and slot connection 7, 8, with the pivoted blades 4, and has a lug 10 which projects through a slot 11 in the base plate 12. The lug 10 is oscillated by a latch 13 which is pivoted at 15 to the master member 16. The spring 24 of the master member is tensioned by means of the arm 23, and is held in the tensioned position by engagement of the arm 18 of the release trigger 19 with a shoulder 17 on the master member. The latch 13 is formed with two arms 27, 28, a light spring 31 engaging the arm 28 to hold the latch 13 against the lug 10. The arm 27 moves the hook end 35 of a spring, latch 30 away from the lug 10 when the latch member 13 is swung during the setting operation. When the shutter is released, the member 13 is oscillated, and the arm 27 moves away and allows the hook end 35 to engage behind the lug 10 and prevent its rebound at the end of the shutter movement.

The halide content of an aqueous chromate solution is reduced by subjecting the solution to electrolysis in a diaphragm-less electrolytic cell whereby at least a portion of the halide e. g. fluoride, chloride or bromide is converted to gaseous halogen and liberated from the solution. The aqueous chromate solution may contain up to 90% by weight of chromate and electrolysis may be conducted at a current density of 0À1-0À2 amps/ sq. inch. The anode may be of titanium coated with platinum or lead peroxide, of lead, or of graphite coated with lead peroxide, and the cathode may be of steel. The anode-cathode gap may be 0À15-0À5. The process may be carried out using a bank of multiple cells connected in series with respect to both the solution and current flow. The process may also be carried out using a cylindrical steel cell, the shell of which forms the cathode, the anode being formed by a circular foraminous platinum-coated titanium screen, and the cell being fitted with a mechanical stirrer.
