Title: Support Arrangement
IPC: E06B11/04
Filed: 1967-12-01
Abstract: 1,182,340. Support for a gate. A. H. QUICK and R. C. WARNER [trading as WALSALL GAUGE & TOOL CO.]. 27 Nov., 1968 [1 Dec., 1967], No. 54700/67. Headings E2F and E2M. [Also in Division A1] A support for a gate or like device consists of an upright base 11 to which is connected an upright bar 14 by means of steel plates 12 and 13 at its upper and lower ends respectively. A washer 15 is attached to the bar 14 and rests on the plate 12 preventing downward motion of the bar, a pin 16 engaged in a hole in the bar below plate 13 prevents upward motion of the bar. Three flaps 17 are pivotally mounted about pins 18 at equally spaced intervals along the base 11, the pins being mounted in the flanges of the base. The flaps are yoke shaped and embrace the bar 14 when in a horizontal position as shown; they are prevented from falling beyond this position by stops 23. The hinge of the device to be supported is slidably engaged on a bar 14 and may be lifted up past a flap in its vertical position, and then supported on the flap when it has returned to its horizontal position.

Title: Positional control of water-borne vessels
IPC: G05D1/02
Filed: 1975-12-16
Abstract: 1485180 Automatic control of position and course DECCA Ltd 16 Dec 1975 [18 Dec 1974]  54756/74 Addition to 1173442 Heading G3R In a system for automatically controlling the position of a water-borne vessel, e.g. a dredger with respect to a reference which may vary with time to define a course as described in the Parent Specification the vertical axis thrusters are replaced by at least two horizontal axis thrusters and a fore and aft propulsion unit. Position is determined by a digital computer from a measurement of the phase difference between radio or acoustic signals transmitted from and received by the vessel, after re-transmission from share stations 6, 8 or underwater transponders, the phase difference being representative of the range from each station. The computer output is two signals defining the position in geographical co-ordinates which are compared with the pre-programmed reference, the result being instantaneous positional error signals which are resolved into orthoganal co-ordinates relative to the ship by combination with a magnetic or gyro compass signal. The resolver output is combined with a heading error signal, derived from the compass, in an undisclosed signal processor which provides the appropriate corrective signals for position and heading to thrusters 9 ... 12 and propulsion unit 14. The thrusters are fixed to produce side thrust only, their effect being adjusted, and reversible, by pitch control of horizontal axis propellors. Manual over-ride is provided and the transmitters, receivers and stations may be duplicated for reliability.

Abstract: 1,218,020. 020. Hydraulic motor control circuits. R. BERINGER K. STERL K. GOGOL F. LEUTENEGGER and W. OLDAHI [trading as BERINGER-HYDRAULIK R. BERINGER & CO.] Dec. 12, 1967 [Dec. 13, 1966], No. 56339. Heading F1P. [Also in Divisions F2 and G3] A bank of spool valves 1, 2 have aligned inlet passages 5, a common drain channel 6a-6c and respective work ports 11, 12 and 21, 22. With both spools in the null positions shown, inlet fluid passes through passage 33 in plunger 31 to act on face 34 thereof to move the plunger to the right to unload the supply pump by connecting passages to drain. A datum pressure determined by spring 32 will then exist in the inlet passages, since the spring chamber 34a is connected to drain via passage 35 and grooves in the spools. When either spool is moved towards a work position, passage 35 is closed and that work port being connected to the inlet is air, connected to chamber 34a whereby the load pressure assists spring 32 and a constant pressure difference, equal to the said datum pressure, is maintained between inlet and load pressures. Over-riding pressure relief is provided by pilot valve 62. The spools may be actuated manually or by electromagnetically controlled pilot valves 91 at opposite ends thereof. Each pilot valve has a spool 75 which can connect line 76 supplying chamber 71 which either drain line 11a or supply line 5a. The pressure in line 76 has access through spool 75 to the right-hand face thereof to balance the electromagnetic attraction to provide proportional control.

In order to avoid distortion of the crosssection of a rectangular steel strand 3, a portion 11 of the mould 2 is tapered so that the solidified shell is held there against the mould wall and cooling is intensified ; in a subsequent portion 12 the cooling is reduced because a gap 13 forms between strand and mould and the conductivity of the mould material may be varied there. -The mould bore at portion 12 may be parallelsided or tapered upwardly. On the water side of the mould wall there may be insulation at the corners. There may be a less tapered portion (16) of the mould 2 beyond the portion 12; this may be followed by another reducedcooling portion (17). The strand 3 is withdrawn by rollers 4. Guide rollers 15 are mounted on the mould or a guide having elements which present a water-cooled guide plate may be mounted on the mould.

Title: Improvements in or relating to ovens for cooking food
IPC: A21B1/02
Filed: 1967-12-21
Abstract: 1,206,415. Heat cleaning ovens. COLUMBIA GAS SYSTEM SERVICE CORP. 21 Dec., 1967 [23 Dec., 1966], No. 58177/67. Addition to 1,133,465. Heading F4W. Food soils within a substantially closed gas heated oven are removed by subjecting them to intense infra-red radiation. An oven heated by an upper infra-red burner 31 and side burners 27, 29 is closed save for a flue outlet 33, and the burners are operated to raise the temperature of the gases in the flue outlet 33 to 1050- 1150 F. and this temperature is maintained for a period during which the side burners or all the burners are turned off. Air is allowed to enter through burners which are turned off, and the burners normally operate with a sufficient excess of air to burn the food soil. Additional small amounts of air may be drawn in through the door seal. The top burner 31 is close to the flue outlet 33 so that any unburnt particles passing to the outlet are subjected to intense infrared radiation before they are exhausted. The cooking operations and the heatcleaning action may be thermostatically controlled. Since the the air used for combustion during heat cleaning is restricted to paths which are subject to the heat of the oven, it becomes preheated.

A reservoir 5 of fixed capacity communicating with the enclosure at its upper part and means for discharging measured quantities of liquid into the bottom of said reservoir to compensate for pressure variations due to the presence of the subject. Enclosure 1, containing pure oxygen, is connected by rubber or plastics tube 10 through rubber or glass stopper 8 to one branch of the glass U-tube manometer 2 containing a liquid and fixed to a support 14. A graduated burette 4 discharges a measured quantity of water through tap 6 into a fixed capacity reservoir 5 on support 14 to force an equal quantity of oxygen from the reservoir into enclosure 1 via tube 11 to remove the differential pressure between the sides of manometer 2 after it occurs due to the subject's breathing. Thus the volume of oxygen consumed less the volume of carbon dioxide exhaled is measured. A film of paraffin oil separates the water from the gas in reservoir 5. During measurements either the enclosure 1 and reservoir 5 temperature is kept constant by immersing them in water bath 13 or their temperature variation is compensated for by a second enclosure of equal total volume connected to the other branch of manometer 2. To measure the total oxygen consumed, caustic soda in the enclosure absorbs the exhaled carbon dioxide. A drying agent may be used.
