Abstract: 398,405. Making foam. DEURS, J. A. S. VAN, 233B, Borups Allee, Copenhagen, and SCHRODER, E., 18, Fjords Allee, Frederiksberg, near Copenhagen. Feb. 14, 1933, No. 4557. Convention date, Feb. 16, 1932. [Class 47 (ii).] In a foam-generating apparatus of the kind in which a foaming liquid and a gas under pressure are forced through a pipe or vessel containing a mixing body of closelyadjacent - transversely-disposed wires, the wires are secured to a supporting member to form a brush which fills entirely the passage-area of the pipe, the free ends of the wires lying in contact with the wall of the pipe. In Fig. 1, the brush arranged in the pipe a consists of wires c secured to a longitudinal stem d. The latter carries a rod f which prevents axial movement of the brush under pressure of the flowing liquid, but provides a means for withdrawing the brush from the pipe when desired. The free ends of the wires lying in contact with the wall of the pipe can yield to allow passage of any impurities carried by the liquid stream. The wires may be of such length as to assume a curved position in the pipe, Fig. 9. In modifications, the wires are secured to transversely-disposed supporting members, with or without gauze filling-pieces. In other modifications, composite brushes having various peripheral configurations are built up from groups of wires secured to several longitudinal rods. The brushes may conform in shape to special shapes of pipes, for example to conical or curved pipes.

Title: Improvements in and relating to electrical telemotor control apparatus particularly applicable to automatic steering
IPC: G05D3/14
Filed: 1940-03-13
Abstract: 577,166. Photo-electric apparatus. CHANCE, E. M. March 13, 1940, No. 4723. Convention date, March 13, 1939. [Class 40 (iii)] [Also in Group XXXV] In apparatus for the electrical control of a variable condition, wherein control action by an electric motor is initiated by the relative movement between two elements and one of them is operated by follow-up means to restore the quiescent condition, the follow-up action is prolonged by movement of the means or responsive to means moved by the electric motor. Thus telemotor error in a steering system may be eliminated or initial rudder may be provided. Fig. 1 shows a system in which photoelectric cells L, R and a beam from a light source 16 constitute the relatively movable elements. A steering motor 25 is operated selectively in opposite directions through a reversing relay 20 as the light beam reflected from a mirror on the compass card falls on cell L or R and a selsyn transmission 38, 39 applies follow-up movements to the cell mounting 17 which surrounds the compass. The relay 20 also controls a reversible motor 24 operating a selsyn transmission 42, 43 to rotate a worm 46 to shift the light source in relation to the compass axis in such a direction as to prolong the follow-up action and so increase the extent of movement of the rudder motor. Adjustable cams operate limit switches 28, 34 to determine the extent of this additional follow-up and these switches may also render the motor 24 inoperative during repetitions of yaw in the same direction. A series resistance 24a determines the speed of the extra follow-up action. The light source 16 may be mounted above the centre of the compass card in a slide operated by the worm 46 or the mirror on the compass card may direct the beam on to a second mirror which is carried by the cell mounting and pivoted so that it may be turned by the worm In a further modification the additional follow-up is derived from 'the normal follow up transmission. The cell mounting 71, Fig. 6 which is driven by the selsyn motor 39, Fig. 1, through worm wheel 57, carries a pivoted pawl arm 62 which engages a circular rack 61 fixed on the gimbal ring so that it will be turned to a limited extent as the cell mounting is moved, the pawl then disengaging from the rack. The arm 62 operates a toothed sector 64 to rotate a spindle 82 carrying an arm 84 on which a pin 86 is adjustably mounted. This pin engages the bifurcated arm of a bell crank which is linked to a slide 76 carrying the light source 16. Fig. 10 shows an alternative arrangement in which the cells C are mounted above the compass card and a pin 96, actuated like the pin 86, rotates a mirror 92 on a pivoted mounting 94. Specification 461,545, [Group XXXV], is referred to.

Title: Improvements in or relating to liquid fuel dispensing apparatus
Inventor: SPALDING ROBERT GEORGE
IPC: G06M1/14
Filed: 1961-02-08
Abstract: 938,748. Counters. WAYNE TANK & PUMP CO. Ltd. Feb. 5, 1962 [Feb. 8, 1961], No. 4773/61. Class 106 (1). A remote indicator for a liquid dispensing apparatus comprises a set of numeral drums loosely mounted on a shaft which is driven in a zeroizing direction at the beginning of each dispensing operation, a frictional arrangement coupling the drums to the shaft until zero is attained. Tne volume and price registers, to the left and right of Fig. 1, operate in like manner. Operation of a pump switch energizes motor 5 to drive shaft 4 on which all the register drums are mounted loosely. Solenoids 14 and 60 simultaneously energize. The former lifts transfer actuating pawls 18 into inoperative position and zero stop members 31, Fig. 3, and 42, Fig. 6, into operative positions so as subsequently to engage zero stops 17 and 41 on the higher and lowest denomination drums respectively. Solenoid 14 also disconnects clutch 8 to disconnect drive to the lowest denomination drum. Movement of pawls 18 allows spring 54 to provide a friction drive from shaft 4 to the numeral drums which therefore rotate in a forward direction to zero positions. Solenoid 60 connects a drive, Fig. 5, to cam 66 to maintain switch 73 open for one revolution after which cam 66 closes contacts 69, 70 to energize the pump motor. The pump motor drives the lowest numeral drum 1 in each register through appropriate gearing. At each revolution of drum 1 a cam 29 closes and opens a switch so that solenoid 22 oscillates transfer pawl 18 to engage pins 16 and advance the next higher drum 3, movement being assisted by spring 50 or not according to whether the speed of the zeroizing shaft 4 is lower or higher than the speed of the drum 1. In the latter case the pawl 18 acts as an escapement. Specification 938,749 is referred to.
