Inventor: SPENCER-GERVOIS TREVOR
IPC: B62J11/00
Filed: 2009-11-03
Abstract: The DollyCrane Frame is made for the low budget filmmaker in mind and for the low budget filmmaking market in general. A standard 25mm metal pole is mounted into the socket where the bike seat is usually positioned. Bolted to the exposed end of this is the main device, an arm effect lever which by rising up and down by hand operates the crane function of the devise while the bicycle itself is pulled or pushed along thereby operating as the dolly. The camera itself is positioned on its own movable head (a tripod head) to counterbalance itself as the arm is lowered or risen. A centre hand twistable bolt is adjustable so that can give easy flexibility for lowering and raising the camera or can be screwed tight into position allowing the camera to be steadied at any height from approximately one foot (30cm) from the ground for very low angle shots up to approximately six or seven feet (180-210cm) in height for high angle shots.

Abstract: 774,495. Taximeters. KIENZLE APPARATE GES. April 12, 1955 [May 25, 1954], No. 10484/55. Divided out of 774,492. Class 106 (3). A taximeter is provided with an initial distance or waiting-time setting device comprising an oscillatory member 21 for driving the fare indicating means, a rotary member 80 which holds the member 21 out of action until a projection 20 thereon falls into a slot 81 in the rotary member, a ratchet wheel 83 which rotates the rotary member 80 and which is actuated at the same rate as the oscillatory member 21, and means for adjusting the initial rotary position of the rotary member. The oscillatory member 21 is driven according to time or distance by a snail cam 24 which engages a projection 25 on the member 21 and the member 21 in turn actuates the driving mechanism of the taximeter by a pawl and ratchet 22, 23. The ratchet wheel 83 is driven at the same rate by a pin 94 on a lever 95 mounted on the shaft 18 of the cam 24. The ratchet wheel has a stop pin 89 which engages with a pin 90 of a setting disc 86. The setting disc is manually adjusted to give the required initial period and is held in adjusted position by a pawl 87. On commencement of a hire, the member 21 is held out of engagement by the curved periphery of the rotary member 80, the ratchet 83 is rotated by the lever 95 from its adjusted position and thereby rotates the member 80 until at the end of the adjusted initial period the pin 20 falls into the slot 81 when the oscillatory member 21 commences its normal drive. At this stage a gap 93 in the teeth of the ratchet 83 prevents further rotation of the ratchet and member 80. Fine setting of the device between the values permitted by the slotted disc 86 may be obtained by adjusting the position of the lever 95 on the shaft 18.

Classes 38 (iii) and 38 (v). [Also in Group XXXV] In a system wherein a single phase welding transformer is energized from a polyphase supply through reversely connected pairs of valves whose firing is controlled by a commutator chain driven by a single phase four pole synchronous motor (see Group XXXV), it is necessary to ensure that the motor 83 runs in one or other only of two positions out of the four which it may have relative to the three phase supply. The motor 83 is started by closing switch 79 which energizes relay 80 through normally closed contacts 861 and closes contacts 80". After a delay which allows motor 83 to stop if running incorrectly ; relay 65 is energized and allows the welding cycle to begin. If the motor 83 starts correctly phased, the voltage supplied to the grid of a valve 74 in series with coil fireclay 86 has the form shown in Fig. 5 (b) and the valve does not fire. This voltage comprises a negative bias injected across resistance 75, an exponential curve derived from circuit 77, and positionally determined by the chair, and peaks injected at 76 from the three phase circuit. If the motor is incorrectly phased relative to three phase supply, the peaks rise above the zero line as shown in Fig. 5 (c), valve 74 fires and relay contacts 86<SP>1</SP> are opened by the energization of relay 86, and the motor stops. Switch 79 is reclosed until motor 83 continues to run. The firing of the valves is controlled by an electric switch comprising commutator chains of the kind described in Specification 533,029, in which the conducting links of the chains receive insulating or conducting studs on which brushes bear. Specification 385,868, [Group XXXV], also is referred to.

Abstract: 1,134,675. Papermaking. CLUPAK Inc. 7 March, 1967 [12 July, 1966], No. 10669/67. Headings D2A and D2B. Newsprint paper of enhanced stretchability containing at least 65% groundwood is made by subjecting a web of the paper while still on the paper-making machine and wet enough to be suitably plastic to compaction in the machine direction by confining it under pressure between a rigid, moving, smooth surface of a rotating element and a resilient surface moving more slowly than the rigid surface and thereafter completing the drying, and optionally calendering. Preferably the wire side of the paper is in contact with the rigid surface. The web may be shrunk by more than the desired final amount and then partially stretched to give the desired final shrinkage. Two kinds of shrinking apparatus that can be placed between first and second drier sections of a papermachine are described. In the first, a thick rubber belt is trained about idler rolls and a stationary bar having a convex surface. This belt is pressed against a heated drum, with the bar at the on-running end of the zone of contact, and the web passes between the drum and the belt. In the second, two rolls are pressed together, one having a soft outer layer of rubbery material, and the other of polished metal. The soft-surfaced roll is connected through universal joints with a braked drum, and the metal drum may be internally heated.
