Title: Soluble asphaltite and method of making the same
IPC: C10C3/10
Filed: 1931-03-20
Abstract: Asphaltites having a fusing point over 250 DEG  F., specific gravity 1,05-1,12, fixed carbon 10-25 per cent, solubility in carbon bisulphide over 96 per cent, are rendered substantially soluble in gasoline and benzol by heating the asphaltite and keeping at a temperature just above its melting point, e.g. 325-400 DEG  F. for about 1/2 hour.  The melting point and volume of the asphaltite is not appreciably affected by this treatment, but the colloidal structure is almost completely destroyed.  The treated asphaltite can be used to impregnate brake linings.

Title: Gear shaping machine and method
IPC: B23F5/16
Filed: 1974-02-26
Abstract: 1442720 Gear shaping STAVELEY MACHINE TOOLS Ltd 18 Feb 1975 [26 Feb 1974] 8697/74 Heading B3L  In a method of gear-shaping in which the cutter 2 is in the form of a gear, is axially reciprocatable and rotates simultaneously with a blank 1, and a feed cam 5 which causes the cutter to advance towards the blank to increase the depth of cut, control means is provided to stop the feed cam whilst the cutting action is in progress, measuring the rotation of the workpiece blank and re-engaging the infeed by rotation of the cam 5 after the workpiece blank has rotated through a given angle. A fast approach between the work-piece blank 1 and the gear cutter 2 is effected by fluid pressure means 15, 16 which brings the work table 14 into engagement with a push rod assembly 11, 7, 8, the rotation of the cam then permits a controlled infeed between the cutter and blank. The rotation of the cam 5 and angular rotation of the workpiece 1 are controlled by a switch drum 17 with actuator stops 18 which engage switch 19 so that the cam 5 can be stopped and the workpiece and gear cutter rotated through a given angular rotation so that the blank is cut in this one rotation, the central means then activates the cam 5 to produce a further infeed. The cam is then stopped whilst a second cut is made as the blank is rotated through a further angular rotation. In this manner a series of successive cuts are made to produce the gear in relation to a series of distinct in-feed movements produced by the stopping and starting of the cam 5.

Title: Improvements in or relating to vertical card indexes
IPC: B42F17/00
Filed: 1939-03-18
Abstract: 526,533. Indexing ; card indexes. VOSSEBRECKER. W.. SCHMIDTMANN, W., and SCHMIDTMANN, A. March 18, 1939, No. 8747. [Classes 16 and 146 (i)] In order to avoid the use of projecting tabs in a vertical card index, in which the index cards are subdivided into groups by guide cards, both the index cards g, Fig. 4, and the guide cards d, Fig. 3, are formed on their upper edges with stepped cut-away portions, so as to form index trips or corners i, m for receiving index markings, and the index cards have portions of reduced height formed by shoulders k, so that the markings of one group of index cards are visible below those on the guide cards, as shown in Fig. 1. Alternatively the markings on the guide cards may appear below those on the index cards. The index fields on the two sets of cards may be displaced laterally with respect to one another, instead of vertically. The index fields extend over only a part of the length of the cards, and the remainder may be utilized for clip-on markers, or for notches q indicating group membership. Each guide card has a row of holes n through which are visible error or omission markings o on the index cards, the absence of such a marking indicating that a card is missing or misplaced. The index markings representing groups of cards may be carried on the index cards themselves, and separate guide cards are then omitted. The box a containing the cards is made wider than the cards, and its base is provided with a rib b to engage either of two vertical slots in the cards. Any card can thereby be displaced laterally, in order to draw attention to it.

Title: Improvements in or relating to a liquid manure distributing apparatus
IPC: A01C23/00
Filed: 1961-03-10
Abstract: 1,007,251. Spray-producers. J. FLEMING. March 26, 1962 [March 10, 1961], No. 8779/61. Heading B2F. In a liquid manure distributing apparatus, for coupling to a tractor, to fill a tank 8 a vacuum is created in the tank by connecting the suction side of an air pump 11, Fig. 2, driven by the tractor power take off shaft, to the tank by means of a valve 14 and a pipe 22. To expel liquid the valve is positioned to connect the pump outlet side to the tank. Fig. 5A shows the filling position of the valve where a pump outlet port 18 is in communication, via a groove 27 in a rotatable valve cap, with a port 19 which is in communication with atmospheric pressure, and a pump inlet port 16 is linked via a groove 27 to a tank port 17. Fig. 5b shows the liquid expulsion position of the valve cap to which the cap is spring urged. To prevent overfilling there is provided a ball float 31 coupled to a pointer and to an adjustable trip linkage 30, 33, 34 which engages a projection 29 on the valve cap during filling and disengages when the tank is full allowing the spring to move the valve cap to the expulsion position thus breaking the vacuum. Alternatively a conventional float valve may be provided on the tank to break the vacuum, and the valve 14 may be manually operated i.e. without the trip means. The discharge outlet, Fig. 1 (not shown), is manually operated, and the discharged manure impinges on a rotary distributer plate driven via gearing and a clutch from the tractor power take-off shaft.

Title: Improvements in or relating to apparatus for transmitting cinematographic films by television
IPC: H04N3/36
Filed: 1957-03-18
Abstract: 855,388. Television. FERNSEH G.m.b.H. March 18, 1957 [March 17, 1956], No. 8817/57. Class 40(3). Relates to apparatus for deriving television signals from a kinematograph film 8 in which the film is traversed through a gate 5 illuminated by a source 3, an image of the gate being projected upon the light-sensitive member of a television camera tube 11 by means of an optical system 7, 14. In accordance with the invention, the optical system is formed of two separate lenses or lens systems, the first, 7, being mechanically rigidly connected to the structural elements which determine the position of the film gate whilst the second, 14, is rigidly located with respect to the structural elements which determine the position of the camera tube. Furthermore, each lens is focused to infinity whereby all the rays emerging from any point of the film frame pass between the lenses along parallel paths. By this means, the slight variations in alignment between the components of the optical system, which are inevitably produced by the vibrations of the projector, have little effect upon the quality of the projected image, since the position of the image is no longer affected. In a preferred arrangement, a ratio between the focal lengths of the two lenses of 1:1À25 is used, the lens of shorter focal length incorporating the aperture stop and being attached to the film projector. The optical path between the two lenses is enclosed in order to exclude stray light. An arrangement for doing this where the support for lens 7 is hinged to permit access to the film gate is described, Fig. 2 (not shown).

IPC: B61J1/10
Filed: 1941-07-12
Abstract: 549,618. Loading and unloading ; traversers. MORRIS, Ltd., H., and BRATLEY, M. J. July 12, 1941, No. 8840. [Classes 78 (iv) and 104 (ii)] Trucks or containers are handled or sorted by traversing them either from a storage line at one side of a traverser to a parallel line on the other side of the traverser or from one position to another on the same line, the traverser comprising a main carriage A, Fig. 5, movable along a track parallel with the storage or loading lines, and a two-part telescopic subcarriage D, E movable transversely of the main carriage, the part E being adapted to lift and transport the load to be handled, and means being provided for preventing movement of the main carriage unless the parts D, E are in midposition on the carriage A. In the construction shown the main carriage A runs on rails C between two parallel storage or loading lines and is driven through shafts R by a hydraulic motor Q from an electrically-driven pump P. The sub-carriage D travels on the main carriage A and the truck carriage E travels on the subcarriage D, so that E can extend beyond the main carriage, as shown in Fig. 1, uutil elevating arms F are beneath a truck G. The subcarriage parts D, E are simultaneously driven by rams Q<SP>2</SP> which are connected thereto and to the main carriage by compound rock-and-pinion gearing such that while D moves from side to side of A, E moves from end to end of D. When the arms F are beneath a truck G they can be raised to lift the truck by means of a ram R<SP>1</SP> supplied by a pump P<SP>1</SP> driven by a motor Q<SP>1</SP>. When the arms E are in approximately mid-position on the main carraige A a switch is closed which closes a by-pass valve in the circuit of the hydraulic motor Q and allows the latter to drive the main carriage. The main motor Q is also controlled by ramps at the end of the traverser rails C, these ramps acting through levers and linkage to stop the motor automatically as the traverser reaches the end of its track.

Abstract: 1,272,293. Batch weighing. T. BAINBRIDGE. 19 Feb., 1970 [19 Feb., 1969], No. 8870/69. Heading G4H. Apparatus for determining the number of similar articles in a batch by weighing the batch to generate an electrical signal which is compared with the signal derived by integrating a signal representing a single similar article or a predetermined number (for example 10) of similar articles, clock pulses at a predetermined frequency are counted until a comparator 3 (Fig. 1) indicates equality of the two signals. In the embodiment, Fig. 1, a tare weight is set on potentiometer 13 a comparator 7, at equality of the tare weight signal and the signal derived by integrating the signal from a scale 4 weighing a sample article, enabling a gate 12 to pass the clock pulses via a divide-by-ten circuit to pulse a counter 11. At equality of the integrator signal and signal from a weigh scale 1 receiving the batch comparator 3 closes the gate. The binary coded decimal count is then read out to a store the contents of which are decoded and displayed. If the articles are small, ten samples may be placed on the scale 4 and the divide-by-ten circuit by-passed. To prevent fraud, any A.C. components in the scale outputs are amplified and the resulting signal used to inhibit the gate 12. A predetermined number of articles may be batched by continuously comparing the count with a preset number, a control signal being generated at equality to stop the feed of articles to the scale. In a modification (Fig. 2, not shown) a staircase signal is used for comparison. This is derived by applying the output of scale 4 to a transistor chopper (6A) pulsed by a source (18). The pulses from the chopper; the amplitude of which represents the weight of the sample, are integrated each pulse also being counted in a counter (13A) until equality of the staircase and batch signals.

Abstract: 675,895. Electromagnetic interrupters. LEVY, B. R. April 13, 1950. [April 14, 1949] No. 9145/50. Class 38 (v). [Also in Group XXXVIII] A turn-indicating signal lamp system for a vehicle (see Group XXXVIII) is characterised by the provision of a flashing device comprising a tiltable mercury switch associated with an electromagnet arranged to automatically and repetitively tilt said mercury switch when energized. Current from a battery 1 may be supplied via the signal lamp system selector switch 10, 20 to a contact 2 of a mercury interrupter 3 mounted on a carrier 16 pivoted at 17 and normally maintained by gravity in the position shown in full lines. The second contact 4 of the mercury interrupter is connected to a solenoid 6 having a plunger 19 linked to the carrier 16, so that when current is supplied from battery 1 the carrier 16 is tilted into the position shown by chain-dotted lines, thus breaking the circuit between contacts 2 and 4 and de-energizing the solenoid 6. The device then reverts to the original condition under action of gravity and reconnects contacts 2 and 4 causing the cycle to repeat. A switch 15 is connected across contacts 2 and 4 to render the flashing feature inoperative if desired.
