Patent GB-131590-A (GB)
IPC: H01C10/02
Abstract: 131,590. Akt.-Ges. Brown, Boveri, et Cie. Aug. 17, 1918, [Convention date]. Resistances.-An adjustable resistance comprises two or more liquid resistances having different characteristics, their movable and fixed electrodes each being connected mechanically and electrically, and one resistance at least being of the tubular type, i.e. with a column of liquid variable in length. The resistances may be brought into circuit successively. In one arrangement, movable electrodes 18, 19, Fig. 2, are carried by a cross-piece 11 guided vertically and linked to an arm 9 on an operating shaft 10. They are connected by flexible conductors 21 to a terminal 22. One movable electrode 19, which first enters the liquid, co-operates with an annular electrode 6. This, with upper and lower tubes 4, 5 of earthenware or cement, forms a passage a little larger than the electrode 19 and situated so as to allow free circulation of liquid. The other electrodes 18, 23 consist of plates, the fixed one being situated at the bottom of an insulating tube 7. Instead of plates, there may be used grids made up of sloping bars, or of separate roof-like or conical parts; another arrangement is shown in Fig. 5. The two resistances may be in eeparate vessels or in separate compartments of the same vessel; instead of the liquids being at different levels, they may be at the same level. the electrodes being arranged accordingly. The upper electrodes may be hung from different crankarms, which are moved during different ranges of motion of the operating shaft 10. The electrode may be extended over the whole length of the lower tube 5, or an additional electrode may be provided at the bottom of the tube. Fig. 7 shows an alternative construction with one movable electrode 18 over the other 19, one fixed electrode being represented by a flange on the other fixed tubular electrode. A combination of two resist. auces may have a characteristic curve as shown at c or e, Fig. 1, in which the abscissµ represent movement of electrodes and the ordinates the resistance. The point of flexure II corresponds to the immersion of the second movable electrode. Curve d represents a combination of three resist. ances. Curve a is that of a simple plate resist. ance, and b that of a simple " tubular " resistance. The combined resistances are useful for starting and controlling motors. Three such sets may be used for three-phase motors.

Heading B7T. An air and electric service line coupling assembly comprises a contact box 1 connected by means of arms 4 and 9 to an automatic coupler 6 for moving the box forward to the line of engagement 3 with a mating box, the box carrying a centring pin 15, an aperture 16 for the reception of a mating pin, a latch mechanism 20 for locking the mating pin within the aperture and an L-shaped lever 26 which keeps a pusher 8, adapted to keep the latch in its locked position during coupling, spaced from the latch when the box is not connected. During a coupling a sleeve 7 of the coupler 6 moves rearwardly and causes the box 1 to be moved up to line 3 where pin 15 enters aperture 16 in the mating box. The pins 15 contact the latches 20 in their mating boxes causing them to fall under gravity until protrusions 21 enter grooves 17 of the pins to lock them in position. Also each pin 15 contacts a lever 26 moving it to a position whereby a pusher 8 under the action of arms 4 and 9 causes a part 24 thereof to lock the latch in position. The electric contacts on the end of pusher will then be connected to mating contacts. A push-pull cable 47 is connected between box 1 and a mechanism 38 so that on coupling a stop 51 of the mating box pushes the cable inner core to release a piston of the mechanism 38 which rotates rod 35 and via lever 36 opens air valve 34 in the air line. On disengagement the reverse operation is carried out and the components take up their initial positions.

Abstract: 494,846. Knitting-machines. HEMPHILL CO. May 8, 1937, No. 13209. Convention date, May 14, 1936. [Class 74 (ii)] A machine having means for feeding yarns in plating relation is provided with means for catching and moving one of the yarns so that it will feed at an angle to the other yarn appreciably greater than that at which it would normally be fed by the feeder. The yarn engaging member consists of a hook 20, Figs. 3 and 10, that is slidably mounted in a bracket 17 on the latch ring 5 and is movable tangentially of the needle cylinder under control of a spring 26 and a bell-crank lever 23-25. In Fig. 10 one of two yarns 66, 65 supplied by a feeder 16 is engaged by the hook 20 and drawn away from the other varn so as to be fed close to the needle circle. The movement of the hook 20 to operative position is limited by an adjustable member. For patterning purposes, e.g. during the knitting of the leg and foot of a stocking, the lever 23-25 is operated by a stud 49 on a rod 47, Fig. 6, that is lowered, against the action of a spring 50, by lever and link connections 43, 44 from a lever 41 controlled by a pattern wheel 38. To avoid special timing of the pattern wheel 38, cams 54, 55 are provided on a drum 53 on the cam shaft 10 to operate the lever 41 and hook 20 at the beginning of the leg and foot respectively. The hook 20 is moved and held out of range of the yarn guides during the knitting of unornamented parts, e.g. the heel and toe, by a lever 36 operated by the clutch actuating lever. To facilitate release of the yarn 65 by the hook 20 during yarn changing, the guide 16 is withdrawn in two stages by the action of stepped cams 59, Fig. 6, on a lever 60 associated with the yarn guide controlling fingers 12. Specifications 344,486 and 383,731 are referred to.

Abstract: 475,098. Joints for structures. HOSSENFELDER, G. May 11, 1936, No. 13315. Convention date, May 13, 1935. [Class 20 (ii)] [Also in Groups XIV and XVII] Parts of structures are connected together by means of a projection in the form of a solid of revolution on one part entering a corresponding recess provided in the other part. The interfitting projections and recesses are formed by the rotation of a plane a<1> about a line PP, at least one of the lateral faces of the projection or recess being inclined to the axis of revolution to form inclined abutting surfaces a2, d2, respectively. The edges of the generating plane may be plain or notched and interfitting subsidiary recesses and projections a<4>, d<4> may be formed on the abutting edges of the main projections and recesses respectively. The projections and recesses may be formed on the members to be joined directly or on separate fittings attachable to the members. Alternatively, a key formed as a solid of revolution may be inserted in a corresponding recess in a member g, Fig. 11, another member h with an end recess being rotated to engage its recess with the upstanding portion of the key; alternatively, the recess in the member h may be continued to the outside surface and after engagement with the key the space may be filled in. As applied to a structure as shown in Fig. 12, the key-projections are arranged on the ends of the members such as m, l, so that for engagement with other members, the directions of rotation of the members joined are alternatively reversed, so that the previously made joints are locked. Narrow members such as bands may be engaged by providing them with interfitting projections and recesses formed according to the invention.

Abstract: 257,546. Romer, J. F. May 28, 1926. Prisms; three-colour and like systems.-A number of images of the same object from the same point of view and alike in regard to size and outline are produced by a number of refracting and reflecting surfaces in the form of prisms. Colour filters disposed in the paths of the rays enable the images to be used for colourphotography. The example shown in Fig. 1 produces two mutually reversed images in the same plane. The rays from an object O after passing through the lens L are refracted by the surface X<1> of the prism <pi> on to the semi-transparent surface S common to the two prisms P\ P<2>. The rays are divided by this surface S and emerge from the systems by the surfaces X<2>, X forming images M<1>, M<2> in the same plane, laterally reversed. By extending the prisms, as in Fig. 3, and providing additional prisms P<3>, P<4> with additional semi-transparent surfaces S<1>, S<2>, four images M<1> - - M<4> arranged as shown are produced. By dispensing with the prism P<4>, three images are formed. In modifications the lens L is replaced by lenses situated between the emergent surfaces of the prisms and the plane of the images, and in a further arrangement the rays from the surfaces X<2>, X', Fig. 1, are received on the first surface of a similar pair of prisms arranged with the semi-transparent surface at right angles to that of the first pair of prisms, producing a group of four images arranged as in Fig. 9. In all cases the semi-transparent surface is in a plane parallel to the optical axis of the lens L.

Title: Improvements in and relating to pencil and like holders
IPC: B43K29/02
Filed: 1919-05-28
Abstract: 138,251. Keeran, C. R. May 28, 1919. Pencil and like holders; erasers.-Relates to (1) lead-propelling mechanism, (2) means for propelling an eraser, (3) magazines for reserve leads, and (4) pocket clips. (1) The lead is propelled in a central tube 12, Fig. 1, by a plunger 20, Figs. 3 and 5, having threaded engagement with a sleeve 36, which is connected with a. rotatable head 31 carrying an eraser 32. During the forward movement, rotation of the plunger 20 relatively to the tube 12 is prevented by means of a fin 21, Fig. 5, on the plunger and one or more longitudinal flutings in the tube. At the end of the forward movement, determined by a shoulder 19 on the tube, the fin emerges clear of the flutings, and hence the plunger is then free to rotate, and so does not prevent continued rotation of the head 31. The lower ends of the flutings are bevelled to facilitate re-engagement with the fin. The tube 12 is secured to the body 11 of the pencilholder by means of a tip 15, Figs. 1 and 5, and a ferrule 14 at the lower end, and at the upper end 25, Fig. 3. by means of a cap 22 keyed to the body 11. The head 31 and the associated sleeve 36 are mounted on a collar 23 which screws on the cap 22. The head 31 and the sleeve 23 are formed with abutting flanges 35, 30, and are secured together in rotatable relation by means of a washer 41, and either a depending thimble 39 on the flange 35 or a separate bushing. (2) The eraser 32 is propelled in the head 31 by means of a threaded plate 48, Fig. 3, having a relatively loose connexion with the head; as shown in Fig. 3, the plate 48 has longitudinal play is square cut threads. The eraser can be adjusted by pressing it to hold it stationary, and rotating the head 31; or by holding the head 31 stationary, and pressing the eraser with a rotary movement; or by rotating the head 31 while there is a temporary connexion of the plate 48 with the plunger 20, for which purpose the plate is provided with a threaded boss 50 firmed with slits 51 or otherwise adapted to facilitate register with the threads on the plunger; or alternatively, the end of the plunger is coned or otherwise shaped to fit in a corresponding socket in the boss. The eraser is secured to the plate 48 by upstanding projections on the plate. (3) A magazine for reserve leads is formed around the tube 12 by slots 26, Fig. 1, in a solid body 11 of wood, fibre, &c., and the cap 22 is formed with registering apertures. In the case of a hollow metal body 11, Fig. 6, the magazine is formed in sections 64 having radial walls 65 and sprung into place, thin resilient material such as aluminium being used. The ends of the leads protrude beyond the body, and are enclosed by the collar 23, Figs. 1 and 3. (4) A pocket clip 70, Figs. 1 and 3, is permanently attached to the pencil-holder by means of a tongue 72 formed with a head 74 and a shoulder 73, and seated in corresponding recesses in the cap 22 and the.body 11.

Abstract: 1292568 Storage addressing system INTERNATIONAL BUSINESS MACHINES CORP 7 May 1971 [12 June 1970] 13623/71 Heading G4C A storage file, e.g. disc, drum, tape, delay line, is divided into blocks, each of which contains a plurality of data files and a directory containing the names of the data files in the block and their intra-block addresses, the data file names are used for pointing to the block in which the files are contained, a pointed-to block is accessed first at its directory to obtain the intra-block address of a desired data file by comparison of file names, and then at the remainder of the block to obtain the desired file by comparison of intra-block addresses. In the described embodiment, the file names are processed by a hashcoding algorithm to obtain the block pointers and while a disc transducing head is being moved to access the block containing the desired file, the file name is entered in a register 12. When the appropriate block is being accessed, its directory is searched in real time by reading the directory serially by bit into a shift register 10 and comparing the contents of one section of the register 10 with those of register 12 in a comparator 22. On detecting a match, the intra-block start address of the desired file and of the following file (or the file end address if the desired file is the last in the block) are transferred to registers 14, 16 for subsequent comparison with an incremented intra-block address register 18 which is started when the end of the directory is reached. The begin and stop read signals from comparators 28, 32 are used to transfer the desired file from shift register 10 to an output device. By adding duplicate circuits, more than one file may be accessed from a block in a single seek and read operation, and the files may be of variable length.
