Patent GB-1210387-A (GB)
Title: Ship propeller drive device
Inventor: HEIN DIETER
IPC: B63H3/10
Filed: 1967-11-13
Abstract: 1,210,387. Automatic control of ship propulsion. INSTITUT FUR SCHIFFBAU. Nov. 13, 1967, No.51488/67. Heading G3R. In a system involving co-ordinated control of the speed and pitch of an engine-driven ship's propeller, consecutive periodic measurements of fuel consumption per engine revolution are compared and the speed and pitch automatically adjusted until the fuel consumption per revolution is a minimum. As shown, a signal dependent on the speed of a ships' propeller 11 driven by an engine 6 is produced by a transducer 9 and compared with a desired speed signal selected by manual adjustment of a lever 1 so that any difference is effective to correct the speed by operation of an engine speed governor 5. Signals which are a function of propeller thrust and pitch are produced by transducers 12 and 13 and compared with a desired value selected by adjustment of a lever 19 controlled automatically by a member 18 in correspondence with lever 1, or manually, so that any difference is effective to vary propeller pitch by operating a controller 14 through means 15 which limit the variation if fuel consumption is excessive. The quantity of fuel used per engine revolution is computed at 7 from a fuel-flow transducer 8 and speed transducer 9 and periodically stored and compared with the previous measurement at 16. Any differences cause adjustment of the speed datum and, by virtue of thrust transducer 12, the pitch datum, until fuel consumption per engine revolution reaches a minimum. If a unit 2, responding to transducer 9, detects that a critical speed has existed for more than a predetermined time it causes a shift away from this speed.

Title: Improvements in or relating to apparatus for Discharging Filter Cake in Continuous Filters of the Disc or Drum Type
Inventor: GASH FREDERICK
IPC: B01D35/20
Filed: 1965-12-14
Abstract: 1,162,817. Rotary filter. SIMONACCO Ltd. 29 Nov., 1966 [14 Dec., 1965], No. 52988/65. Heading BID. [Also in Division H1] The inward flow, multiple disc or drum element(s) 11 of a rotary filter is/are divided into sectors, and filter cake is removed therefrom at a particular angular position by means of a reverse flow pulse of gas delivered from a reservoir 24 through pneumatic valve 22, which is controlled by a timer 17 to open for a predetermined period at times when the shaft 10 of the filter is in predetermined positions. Thus the time but not the duration of reverse flow cleaning is controlled by the shaft rotation, and a sector may be cleaned for example only once after every six revolutions through the slurry. Geared to the shaft 10 is a vane 15 which coacts with a magnetic proximity switch 16 to start timer 17. Vanes 15 and gears may be changed to alter the cleaning sequence and frequency, and vane 15 is adjustable angularly on its shaft by a system of venier-like holes (Figs. 3, 4, not shown) to vary the shaft position at which timer 17 is actuated. Timer 17 produces an electric pulse of adjustable duration which operates solenoid-valve 18 to open valve 22. As shown, the diaphragm 21 which actuates valve 22 is supplied with compressed air from a compartment 26 connected to main compartment 24 by a one-way valve 27, but the compartments could be separate. Reservoir 24 is supplied by a compressor 25. Vacuum lines (44, 45) serve to pick-up slurry and to dry it on sectors in positions angularly upstream of the discharge position, lines (44, 45) and 13 being connected sequentially to ducts 9 in shaft 10 leading to various sectors by rotary valve 12 (Fig. 6, not shown). A channel (47) connecting lines 13, (44) in the valve facilitates rapid depressuring of line 13 after valve 22 closes to deflate the cloth covering the filter elements before it can foul solids collection members. The valve 20, 22 is designed for rapid opening compared with its 'open' time.

Abstract: 1316503 Self-processing cameras POLAROID CORP 23 Nov 1970 [21 Nov 1969 28 Nov 1969] 55626/70 Heading G2A The apparatus disclosed is generally the same as that disclosed in Specification 1316502, the claims being directed towards the distribution of a processing composition during the outward and reverse movement of the film units from a forward position in the container to a rearward position. As in Specification 1316502, the stack of film units 24 is housed in a container 32, having a spring-urged divider 50 which pushes the units forward so that the top one is positioned in the exposure window 36, and which also divides the container into forward and rearward compartments. The container 32, when loaded into the camera, is supported in an inner frame 69 having side walls 70 and a front wall 72 having an exposure opening 36a. The reciprocating movement of the film units is effected by means of a sliding drawer 96, which runs on a system of guides and ball bearings. Racks 112 having flanged teeth 114 are secured to the side walls 100 of the drawer 96, and these teeth are engaged by pinions 116 on the shaft of the upper processing roller 82. After an exposure has been made, the rollers 82, 84 begin rotating, driven by a motor energized by a battery incorporated in the divider 50, and the exposed film unit is fed forward to the rollers as described in Specification 1316502. At the same time the drawer 96 moves out to accommodate the film unit as it passes between the rollers, and the processing liquid from the ruptured pod 30 is spread between the sheets 26, 28 of the unit Fig. 5 (not shown). An opaque curtain 144 is secured at one end to a support member 146 and at the other end to the rear wall of the camera behind the rollers. As the drawer moves out to its extended position, the curtain is also drawn out to form a light-tight enclosure. After the drawer has been fully extended, it actuates a switch which reverses the polarity of the current driving the motor, so that the drawer is retracted again. As described in Specification 1316502, the film unit is now returned to the rear of the divider 50.
