Title: An improved metering tank for use with mixing machinery
IPC: B28C7/12
Filed: 1949-06-01
Abstract: 686,753. Delivering measured quantities of liquid. HARRISON, K. J., ABBEY, C. B., SKELTON, J. L., and LINER CONCRETE MACHINERY CO., Ltd. June 1, 1950 [June 1, 1949]. No. 14679/49. Class 106 (v). A float controlled measuring tank comprises a valve member 7a acting on a seating 5 in the inflow pipe 4, the valve member being mounted on a vertically movable guide rod 7 which is controlled by a float 8 movable with respect to the rod, and means, for example the linkwork 9, 11, so that when the outlet valve 12 is opened by the pull rod 13 the inlet valve is. closed. The float may be threaded on to the rod 7 and the rod rotated by means of spur wheels 15, 16 and a handwheel 19 or remotely by a shaft 22, or the float may be slidable on the rod 7 and a lever or cam interposed between them. A vertical strip 24 engages in a slot 1a covered by a viewing glass 23, to serve as an indicator and constrain the float against rotation. Alternatively the depth of water may be indicated by a pointer driven by a train of gears from the handle 19 or by a rod attached to the float which passes through the top of the tank and carries a pointer arm traversing a scale on the side of the tank. Specification 686,793 is referred to.

Title: Improvements in grates for gas generators and furnaces
IPC: C10J3/34
Filed: 1925-06-05
Abstract: 236,185. TrÚfois, L. June 24, 1924, [Convention date]. Grates.-The rotary hearth of a gas producer or other furnace comprises two (or more) portions of helical form, the generatrices of which pass on the one hand through a fixed pcint on the axis of rotation of the grate and on the other hand through different points on a peripheral helical curve. Each portion of the hearth is provided with numerous apertures 7, with horizontally disposed undershields directed away from the direction of motion of the hearth. The body of fuel thus receives upwards displacements sufficient to prevent it from clinging to the walls and the apertures 7 provide for easy clearance of the ash. The hearth is carried and guided by rollers 3, 4 and rotated by a rack 5.

Abstract: 119,548. Huffam, G. April 2, 1918. Check lift valves; closure members, compound.-A valve device for controlling the flow of one or a mixture of fluids, and particularly applicable for controlling the supply of explosive mixture to an internalcombustion engine, has a check lift valve loaded by a spring adjusted by a rotatable and slidable member which a.lso acts to throttle the passage or passages through the valve casing. The check valve 19 is loaded by a spring 20 bearing against an abutment 22 on the valve spindle 17 and adjusted by a cylindrical member 14. The upper part of this member, which is adapted to rotate and slide in a stuffing-box 23, is closed by a cap 15. The stuffing-box has packing 26 compressed between a, lower plate 27 resting on a ledge 28 and a gland 25 screwed into an enlarged part of the casing. The lower part of the member 14 has a port 29 adapted to register, more or less, with ports 9, 9<a>, 9<b> in the casing. In a modification, the casing has a single port 9 and a second spring is arranged between the adjustable member and the valve member. The valve member is also made double-sided so that the device can be assembled to work on one side or the other of a reversible seat.

Abstract: 1,033,499. Endless conveyers. E. FEHRER. April 7, 1965 [May 19, 1964], No. 14806/65. Heading B8A. Fibre on an endless conveyer belt 2 is transferred to a transversely disposed endless conveyer belt 1 by a rotating member 7 on a shaft 6 having a free-wheel action. The member 7 is driven by a pin 11 carried by a sprocket continuously rotating in a clockwise direction. In operation, the member 7 is picked up by the pin 11 and lifted upwards until it falls under gravity and acquires a momentum for effecting the transfer of the fibre. The freewheel mechanism prevents the member 7 falling backwards and interfering with the continued feeding of the fibre.

Title: Sweep demand system
IPC: G06V10/12
Filed: 1964-04-09
Abstract: 1,045,079. Optical apparatus. FARRINGTON ELECTRONICS Inc. April 9, 1964 [April 10, 1963], No.14828/64. Heading G2J. [Also in Division G4] In a character reading apparatus the scanner comprises a tilting mirror 12 adapted to project a moving image of the characters over a dissecting disc, the mirror being constantly urged in one direction by a first driving means and returned after a scanning stroke by a second driving means. Light from a lamp 15 is directed onto the record 11 via fixed mirror 19 and a mirror 13 tilting with shaft 14. The record is held by a member 10 during a scan. The illuminated character is reflected by the mirror through lens 20 and prisms 21, 22 to a dissecting disc inside cover 24. The shaft 14 on which mirrors 12 and 13 are mounted is urged in the scanning direction by a synchronous motor 31 driving a pulley 36, Fig. 2 through a friction clutch 34. The pulley is connected by a metal band to a pulley 38, pins on the pulleys being located in holes in the belt to prevent slipping. For the return movement an electromagnetic clutch 47 is actuated to couple a second synchronous motor 42 to the shaft 14 through belts 45 and 62. This movement is faster than the reverse movement and it causes the clutch 34 to slip. At the end of the return movement a brake coil is energized to stop the motion of the shaft. The brake is then released and the device then begins the next scanning stroke under the control of the first motor and clutch 34. Instead of using two motors only one may be used driving the friction clutch 34 directly and the electromagnetic clutch 47 through gearing.

Title: Automatic operating switch control for burglar alarm apparatus
IPC: G08B29/12
Filed: 1929-05-14
Abstract: 331,985. Bayliss, H. E., Woodrow, A. C., Woodrow, W. J., Woodrow, W. J., and Woodrow, J. W., (trading as Woodrow & Co., A. C.). May 14, 1929. Burglar alarms. - Burglar alarms of the type wherein the protective circuits are operated by the starting, cessation, or alteration of an electric current are provided with a power-driven rotary switch to enable the automatic setting, unsetting, testing and actuation of the apparatus controlling the alarm device. When a protective circuit C, which normally energizes a relay B to hold a movable contact A against a stop M, is broken, the contact A completes a circuit through stop F, electromagnet G, battery H and segments of the rotary control switch K. The armature L attracted by the electromagnet G completes a circuit through contacts N, O and the alarm device O<1>. To set the alarm, a key switch D<3> is turned to connect contacts XK, XL, and the closing of a door or lock makes contacts at XO, XN, XS. A warning-bell XP is thus sounded, and an armature XC is attracted so as to release the source of power XA for rotating the switch K. The rotating switch cuts out the warning- bell, allows current to flow through the protective circuit and energize the relay B, places the holdon circuit ready to operate, breaks the protective circuit, sounds, the alarm, closes the protective circuit, opens the circuit G, closes the circuit of an electromagnet P so as to lift a member S and allow the armature L to fall against its stop and stop the alarm, breaks this last circuit, and finally breaks the circuit attracting the amature XC so that the rotation of the switch K is stopped. The alarm apparatus is now set. The key switch D' is used in conjunction with a switch XH to stop the alarm after the entrance door or lock has been opened.
