Title: Improvements in paper files
IPC: B42F13/28
Filed: 1929-12-13
Abstract: 343,237. Loose-leaf binders. RENGMANN, T., 4, Fredericiastrasse, Charlottenburg, Berlin. Dec. 13, 1929, No. 38284. [Class 146 (i).] In a loose-leaf file or binder of the kind comprising hingedlyconnected prongcarrying members 6, 7, one of which is hinged at 2 to a baseplate 1, means are provided to arrest the hinged member 6 in different angular positions relatively to the plate 1 according to the amount of opening of the prongs desired. In one form, Figs. 1 and 4, the members 6, 7 are wire frames and the prongs 4, 5 are integral therewith. A plate 3 fixed to the frame 6 co-operates with looped parts 8 on the frame so as to form eyelets on which the frame 7 is hinged to the frame 6. Lugs on the plate 3 are hinged at 2 to brackets 18 formed on the baseplate 1 which is fixed to the back of the binder. A lever 12 pivoted on the plate 3 has a projecting part 10<1> adapted to engage notches 19, 19<1>, 20 on the bracket 18 so as to secure the members 6, 7 with the prongs either in the closed, partly-open, or fully-open positions respectively. The notches 19, 19<1> are bevelled so as to allow the part 10<1> to slip thereover if pressure is applied to the frames 6, 7, but the notch 20 prevents movement unless the part 10<1> is released by the operation of the lever 12. Two finger-pieces 21, 21<1> are provided on the lever 12 so that for different quantities of papers in the file the hand can rest on the papers while operating the lever. A curved guide-plate 22 preferably integral with the plate 1 engages the frame 7, and moves it to closed position as the file is closed. A similar plate 23 may be attached to the adjacent cover member so as to form a continuation of the plate 22 when the cover is closed. In a modified form, Fig. 8, in which the members 6, 7 are prong-carrying plates, a toothed member 11 operated by a lever 12<1> through a spring-controlled rod 10 engages the member 6 and secures it in the required position. An additional spring-controlled catch 13 on the member 6 adapted to engage a notched plate 14 on the member 7 may be provided to secure the plates 6, 7 in any desired relative position, the catch being moved to locking position against the action of the controlling spring by the member 11 contacting with the catch 13.

IPC: H03K17/81
Filed: 1958-11-28
Abstract: 903,095. Circuits employing bi-stable magnetic elements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 27, 1959 [Nov. 28, 1958], No. 38507/58. Class 40 (9). One of a number of load circuits such as RA, Fig. 4, is energized by switching a transistor TA, the emitters of all such transistors being connected to a common point Y by way of windings b on associated cores such as A, the transistor TA being switched when the potential of the point Y is raised in coincidence with the potential induced in winding b by switching of core A by drive winding c. The potential of common point Y is raised by switching transistor TCS. Each core A is set preparatory to energizing a load RA by means of a winding a. Figs. 2 and 3 show the invention applied to a ring counter. The pulses of Fig. 3 are applied to the terminals DRIVE 1, DRIVE 2, and DRIVE 3. Supposing that core I is set, which may be done selectively by means of windings d. The DRIVE 3 pulse raises the potential of windings b of cores I, III and V, while the DRIVE 1 pulse resets core I. Transistor T2 is switched in consequence and the set winding a of core II is energized. With the subsequent occurrence of DRIVE 2 and DRIVE 3 pulses core II is reset, transistor T3 is switched, and core III is set. The cores are thereby switched cyclically, the transistor T1 associated with core VI setting the core I over the connection marked X.

Title: A device for attachment to the lifting cable of a crane or the like for aligning a load
Inventor: POMPE WILHELMUS ANTONIUS MARIA
IPC: E04G21/16
Filed: 1968-08-12
Abstract: 1,243,049. Self-levelling lifting frames. W. A. M. POMPE. 12 Aug., 1968 [11 Aug., 1967], No. 38558/68. Addition to 1,155,410. Heading B8H. When a lifting beam 13, Fig. 1, turns in a clockwise direction due to an asymmetrical centre of gravity a valve 8 is moved to the right controlled by the difference in liquid level in containers 11, 12. The valve 8 controls the flow of fluid from supporting pistons and cylinders 1, 2 to high and low pressure accumulators HP, LP, and thus produces automatic levelling of the loaded beam. When the load is removed the fluid in the accumulators returns the parts to their original positions. In Fig. 2 raising the container spreader 3 forces fluid from a ram 4 to accumulators HP, LP and tilting of the beam is sensed by a pendulum 6. This operates a valve 7 which supplies fluid to a ram 9 which moves the suspension point horizontally until it is over the centre of gravity of the load and spreader. The valve 7 may be controlled by feelers 20, which engage cells of a container ship, or manually by a lever 18. Fig. 3 shows a device for loading into a covered space 20. The beam 7 and load 1 are counterbalanced by a movable weight 3 which is moved by a ram 16 controlled by a valve 15 and a cam 13 attached to a rod 11. An operating lever controlling a valve 19 must be in position I during this period. When equilibrium is reached the lever is moved to position III and the load is lifted. To set the load down the lever is put in position II and this allows the beam 7 and beam 6 to move about on rollers 21, 22. This causes the weight of the load to overcome the counterweight and the load is set down and the counterweight slides down to the left-hand end of the beam 6. In Fig. 4 a counterweight 18 is moved by a ram 8 controlled by a valve 23 and a rod 5. The rod 5 is moved by the tilting of a quiver 3 about pivots 4. Vertical displacement of the counterweight stores energy to return the parts to their original positions. Fig. 5 (not shown) illustrates an embodiment in which the suspension hook is mounted on a trolley which is moved to an equilibrium position by a ram controlled either as described above or as described in parent Specification. Fig. 6 (not shown) illustrates a similar construction in which two rams control the movement of a suspension trolley. In Fig. 7 a container is lifted by cables 1, 2, and the suspension point may be moved to 3a by pulling out a ram 6. Control is by any of the means mentioned above. Fig. 3 (not shown) is similar to Fig. 7 except that the suspension rams extend between a suspension eye and the ends of a spreader bar. Fig. 9 shows a device in which a boom 2 is counterbalanced by a pivoted arm 15 with a weight 16.

Title: Rotary honing tools
Inventor: CASWELL ERNEST
IPC: B24B33/08
Filed: 1958-12-01
Abstract: 860,624. Honing. ALEXANDER MACHINERY Ltd., G. H. Nov. 24, 1959 [Dec. 1, 1958], No. 38614/58. Class 60. A rotary honing tool comprises in combination a plurality of substantially cylindrical sections each having formed in its periphery a plurality of angularly spaced slots extending at inclinations to its axis, means interconnecting said sections in abutting co-axial relationship to form a substantially cylindrical body part, a plurality of honing elements located in the slots of each section respectively, and means axially movable within the body part for imparting simultaneous radial movements to the elements in all sections. The body part is formed by sections 4a, 4b, 4c each having an integral annular flange. The flanges or sections 4c, 4b engage recesses in sections 4b, 4a respectively and the flange on section 4a engages a recess in a hollow shank 11 rotated through a sleeve 12. The sections 4a, 4b, 4c and shank 11 are connected co-axially by screws 5. Each section has in its periphery angularly spaced straight slots 6 inclined to the axis. In each slot is a stone 7 mounted on a holder 8 retained in the slot by a circumferential wire band 9. Each stone 7 has its ends flush with the ends of the section. Each stone holder 8 has a tappet 10 passing radially through a hole in the base of the slot 6 into the bore of the section. The inner ends of the tappets co-operate with conical surfaces 15a, 15b, 15c on a wedge piece 15 prevented by a pin 16 from moving angularly. In screwthreaded engagement with the wedge piece 15 is the end of a spindle 13. The spindle is prevented by a pin 14 from moving axially of the shank 11, but can be moved angularly, resulting in axial movement of the wedge piece to feed the stones outwardly. The mid-points of the slots 6 may, as shown, be in alignment in an axial direction, or the adjacent ends of the slots may be in register in which case the tool can be used to have bores with ports or keyways.

Abstract: 796,490. Voltage measurement. EAST LANCASHIRE CHEMICAL CO., Ltd. Oct. 28, 1954 [Aug. 20, 1954], No. 38723/57. Divided out of 24236/54. Class 37. [Also in Groups XL (a) and XL (c)] Amplification or measurement of a small D.C. voltage is effected by subjecting the electron stream of a discharge tube to an oscillatory deflecting field, so producing in the anode circuit a carrier wave whose amplitude is modulated only by the said D.C. voltage. In the circuit shown, this voltage is applied to the control grid 12 of the tube 10. Anode 13 is connected to an H.T. source via a tuned circuit 17, 18. A coil 14, energized by an oscillator 16 of constant frequency and amplitude, provides the transverse magnetic field, thereby producing an A.C. in the anode circuit whose amplitude varies only with the D.C. voltage on grid 12. The output may have a further amplifying stage 19, and the amplitude is measured by a meter 20, which may be calibrated to read the modulating D.C. voltage directly.

In a method of forming a hollow article, the hollow article is heat softened in a fluidized bed, after which it is subjected to one or more formative operations, and then cooled to harden it. As described, a P.V.C. pipe is heated in either a vertical or horizontal fluidized bed, e.g. of alumina, silica, ballotini or aluminium and is then placed on a jig and bent; alternatively the heated end of the pipe may be formed into a socket. The pipe may be fed vertically into the bed so that the fluidizable medium is present inside and outside the pipe, or it may be fed horizontally into the bed and over a mandrel via an unfluidized section of the bed. Alternatively, the pipe is supported horizontally in apertures in opposed end walls of the bed, which walls are vertically adjustable to allow the pipe to be lowered into the bed. During the bending operation over a lower jig portion, a mandrel is located in the pipe and comprises a flexible metal tube surrounded by a rubber tube which is inflated to engage the pipe interior. After the bending operation, an upper part of the jig is applied and the pressure within the rubber tube increased to remove any wrinkles in the pipe.

Abstract: 1437980 Non-uniform stretching of films HOECHST AG 24 Aug 1973 [28 Aug 1972] 40185/73 Heading B5B The cross-section of thermoplastic film webs is varied by non-uniformly heating the web during longitudinal stretching and varying this non-uniformity so that the temperature distribution across the web changes with time, the temperature differences in the web causing non-uniform stretching of the film. The heating may be by several infra-red radiators, each of which can be separately controlled to obtain the desired effect or by a single heater, separated from the web by a perforated plate which is moved transversely across the web, thereby moving the heat "shadow" and zones of no, or little heating to and fro across the web. Further stretching processes may be effected prior to or after the longitudinal stretching process after which the web may also be thermofixed. Preferred for use in the process are films of polyethylene terephthalate, polypropylene, polyethylene and polyamides. See also Specification 1,437,979.
