Title: Improvements in collapsible boats
IPC: B63B7/06
Filed: 1919-12-03
Abstract: 151,861. Carlo, L. di. Dec. 3, 1919. Collapsible vessels.-An independent collapsible frame structure is covered with a double canvas body consisting of layers of canvas having reinforcing-plates between the layers. The plates extend throughout tbe entire bottom and sides of the boat. The plates 11 in the sides are rectangular, and the plates 12 in the bottom of the boat conform to the curves of the sides. The shell is of a single piece of canvas 2 doubled upon itself to form inner walls 9, 10. Supporting plates 26 provided with thumb screws 28<1> secure the folding frames 48 at the gunwale and the stays 80, 81 maintain the frames in position. Each frame is notched to pass over the sectional keel 55. Gunwale bars 33, which are in sections, hinged to one another, are maintained in position by cross bare 46, also in sections. Vertical struts 64 are also fitted as an additional security. The shell after removal of the frames &c., may be folded longitudinally, accordion fashion, or first transversely, and then longitudinally.

Title: Improvements in or relating to spindle driving mechanism for textile spinning and twisting frames
IPC: D01H1/243
Filed: 1955-10-21
Abstract: 783,935. Spindling driving arrangements. SKF KUGELLAGERFABRIKEN GES. Oct. 21, 1955 [Oct. 23, 1954], No. 30198/55. Class 120(2) A spindle driving mechanism for textile spinning and twisting frames in which each spindle is driven by means of a separate driving wheel through an intermediate wheel is characterized in that the axis of the intermediate wheel is substantially parallel to the axis of the spindle and in that the intermediate wheel is pressed into contact with the driving wheel and the spindle wharve. In the arrangement shown the intermediate wheel 21 is located on a plate spring 23 which is connected with the intermediate wheel 21 and with the casing 10 by angular brackets 25 and 24 respectively. The plate spring 23 presses the intermediate wheel in a direction perpendicular to the line connecting the points of contact between the intermediate wheel and the spindle wharve, and between the intermediate wheel and the driving wheel. The drive is thus transmitted from the shaft 19 through the driving wheel 20 and the intermediate wheel 21 to the spindle wharve 14. The force with which the intermediate wheel is urged into operative position can be increased by providing a helical tension spring 26 or alternately by mechanical means such as weights. The surfaces of the various driving members may be covered with a material having a high co-efficient of friction. To prevent the spindle blade being pulled out during doffing a hook 16 which is yieldably held in place by a rubber sleeve 17 on a fastening screw 18 may be provided. The direction of rotation of the spindles may be reversed by moving the shaft 19 axially so that the rear face of the gear 20 engages the opposite side of the next adjacent intermediate wheel in the spindle line. In a second embodiment the intermediate wheel is of stepped formation so as to increase the spindle speed.

Title: Improvements in or relating to the production of albumen dyestuff products or compounds
IPC: C07K14/76
Filed: 1923-11-30
Abstract: Albumen-dye compounds are prepared by treating albumens such as yeast albumen, nucluic acid, &c., with acridine dyestuffs. Iodine or bromine may be introduced into the dyestuff compounds, either by using in the first place quarternary ammonium iodides or bromides of the dyestuffs, or by treating compounds from the quaternary ammonium chlorides with an iodide or bromide. According to examples purified yeast or blood albumen is treated with 3 : 6-diamino-10-methylacridinium chloride; yeast or casein is treated with 2-ethoxy-6 : 9-diaminoacridine hydrochloride; yeast or sodium nucleate is treated with 3 : 6-diamino-10-methylacridinium iodide, or the product from the methylacridinium chloride is treated with sodium iodide. Specification 156,667 is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the conversion of albumen dye compounds in general into the corresponding iodides or bromides; according to examples yeast is treated with methylene blue and then with sodium bromide, the leuco compound first produced oxidizing in the air; the products from yeast and pyoctanine (methyl violet), or beer yeast nuclein and auramine, or yeast and safranine, is treated with sodium iodide.  This subject-matter does not appear in the Specification as accepted.

Title: Magnetic object detection device
IPC: G01V3/10
Filed: 1976-07-22
Abstract: 1510034 Proximity detectors COMPUTER IDENTICS CORP 22 July 1976 30636/76 Heading GIN [ Also in Division B7] In a rail vehicle wheel detector, the core 16 of a sensing coil 18 disposed adjacent rail 20 is saturated by the field from magnet 12 except when a wheel diverts some of the magnet field and the change in permeability of the core as it changes from saturated to unsaturated state and vice versa and hence the change in coil inductance is detected as a change in frequency of an oscillator circuit 60 of which the coil forms a part. The output from oscillator 60 is counted in counter 66 for successive periods determined by a second counter 74 fed with fixed frequency pulses from reference oscillator 72. Counter 74 via flipflop 76 gates counter 66 on at count T0 and off at T7. The counter 66 provides an output pulse at count 80 and when the core is saturated its permeability is low and the resulting low coil inductance produces an output signal of sufficiently high frequency for the counter to count up to 80 during its gated-on period. This signal at count T8 from counter 74 sets or resets flip-flop 112 to provide a no-wheel signal 119. At count T9 the system is reset for the next count starting at count T0. With a wheel present the core is unsaturated, its permeability rises and the increase in inductance lowers the operating frequency of the oscillator so that count 80 is not reached in the set period and flip-flop 114 is changed over to provide a wheel present indication. To prevent dither when the wheel is moving into and out of the zone of ingluence of the detector, a suppression circuit Fig. 7 (not shown) can be provided to ensure that the wheel present signal is given when the count drops below 80 and is not changed over to wheel absent until the count rises to 90. Two wheel detectors can be provided in succession along the track, Fig. 9 (not shown) and these can be connected to a circuit which additionally provides an indication of the direction of wheel movement.

Filed: 1948-11-30
Abstract: 647,634. Helicopters. PENNINE AIRCRAFT, Ltd., and NEALE, J. S. Nov. 30, 1948, No. 31017. [Class 4] The pitch of the blades of a helicopter rotor is controlled by mechanism comprising a hydraulic system with which each blade is coupled so as to transmit a force into the system when its pitch decreases, and to receive an impulse from the system when its pitch increases, means being provided in the hydraulic system for boosting such impulses. As shown, the rotor blades a are connected to pistons d moving in the cylinders e of a constant volume hydraulic system, a gear-wheel pump h being connected to each of the cylinders by pressure and suction pipes f, g controlled by valves i, the pump serving to boost the forces transmitted to the pistons of those blades whose incidence is increasing. One of the gearwheels of the pump is secured to a stationary shaft passing through the rotor drive shaft, the other revolving with the rotor. The collective pitch of the blades is controlled by a pump m with which is associated a relief valve n, which can be set to maintain any desired lift. In the event of engine failure the blades can be adjusted to the auto-rotative pitch setting by a piston q movable in a pressure cylinder s by a hand lever r, communication between the cylinder s and the rotor blade cylinders e being effected by opening a valve p. Translation of the aircraft may be effected by moving the centre of gravity in relation to the rotor, by tilting the rotor about a universal joint, or by auxiliary propellers.
