Patent GB-162272-A (GB)
Abstract: 162,272. Krupp Akt.-Ges., F. April 22, 1920, [Convention date]. Multiplying and dividing apparatus.-In a keyset multiple-bank independently-operated machine in which multiplication is performed by repeated addition, means are provided for automatically cancelling a number set on the key-board and resetting a number of ten times or of one-tenth the amount of the cancelled number. A lowering frame A on spring-held supports a<1> is actuated through levers a<4> pivoted on shafts a' by a lever a<10>, a<9> joined by a connection a<11> to extensions a<5>. The frame contains a grid of bars b<2>, positioned between the various banks, which are revoluble by a rack G and gears b<5>, axially displaceable by levers b<6>, Fig. 1, and slidably carry for each key place collared spring-held sleeves e', Fig. 10, on which are slidably mounted sleeves F with projections f<2>, f<3>. A slide S, Fig. 16, actuated from a key W, moves in grooves in floating blocks T held by springs t<2> to a fixed frame r<2>, and by springs t<1> to levers U pivoted to a rod V axially movable by a surface s<4> on the slide S which also carries tappets s<1>, s<2>, described later. This slide S on its downward movement is prevented from displacement in the direction due to the stressed springs t<1> by projections s<5> on the slide engaging projections r<3> on the frame, so that the tappet s<2> is only operative on a down-stroke. In a multiplying operation, the first multiple of the multiplicand is produced in the usual manner, then the key W is depressed, and the tappet s<2> on the slide S through a lever b<8>, be displaces the grid in the direction X, Fig. 10, and the pins d' of all depressed keys allow movement past them of the corresponding projection f<2> of sleeves F so that the projection f<3> stands directly over the pin d<1> of the same numeral key of the next higher denomination; also the lever d' is actuated to release the locking-plate D, whereby all keys are restored, the projection d<1> then locking the sleeve in the displaced position. Figs, 9 and 10 show a sleeve looked in this manner. The roller a<12> is next displaced and the whole grid lowered, the projection f<3> carrying down with it the key of the next place, in which position it is looked by the plate D. The grid is raised again by the slide releasing the roller a<12> and the keyboard setting has been multiplied by ten. In a division, the rods b<2> of the grid are turned through 180‹ by the lever G and a similar sequence takes place as in multiplication, but in the opposite direction by employing the projections d <2> A modification is described in which the single lowering-frame with its grids and sleeves is replaced by two lowering-frames with vertical rotating nuts by which the locking of the key of the next higher or the next lower place is effected, switch-like grooves in the nut engaging offsets on the keys.

Abstract: 1,091,330. Sealing cable joints. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. April 14, 1966 [April 15, 1965], No. 16300/66. Heading H2E. A gas-tight seal around a joint between electric cables 1 (Fig. 1), at least one of which is plastics-sheathed, comprises a main sleeve 6 surrounding the joint and soldered, welded or cemented at each end 8, 8<SP>1</SP> to auxiliary sleeves 5, 5<SP>1</SP> themselves similarly attached at each end 12, 13 to bands 10, 11 clamped around the cable sheath 3, the sleeves 5, 5<SP>1</SP> containing a gas-tight material 17 of liquid or liquid-solid mixture. The bands 10, 11 are striated or grooved on the inner surface (14) (Fig. 2A, not shown) to grip a packing strip (16) wrapped around the cable and of the same plastics material as the sheath 3. The bands have perforations (15) so that the packing (16) flows into the perforations (15) when gently heated and during clamping to prevent rotation of the joint. The cable sheath 3 is protected during heating by winding aluminium ribbon around the cable with interposition of glass fibre wool, and after assembly the clamps are removed. The bands and sleeves are preferably of lead. The material of the plug 17 is impermeable to gas and water-vapour, chemically inert relative to the materials of the sheath and sleeves, has a greater coefficient of expansion than those of the sheath and sleeves over the operating temperature range and has a substantially constant viscosity over the same range. Suitable materials are synthetic polymers of normal and refined butylene, or a mixture of pitch and plastics.

Filed: 1972-04-11
Abstract: 1374833 Valves PEGLER-HATTERSLEY Ltd 11 April 1972 [20 April 1971] 16717/72 Heading F2V A three valve assembly consisting of two check and one relief valve, comprises a central body portion 10 the ends of which are in screwthreaded engagement with spigot carrying end caps 12 and 14. Cap 12 anchors a first diaphragm 32 which has a central aperture 34 and which co-operates with a seat member 36 extending from a filter assembly 38. Similarly, cap 14 anchors a second diaphragm 40 which has a central aperture 42 and which co-operates with a seat member 44 extending from a hollow chamber 22 apertured at 27, a further filter assembly 46 being disposed proximate the spigot 16 of cap 14. Flow in the direction indicated by arrows, tends to move both diaphragms away from their respective chambers so creating a flow path 16, 38, 34, 23, 27, 42, 46 and 16. Should the pressure differential across the assembly fall below a certain value, then diaphragm 40 is seated against member 44 and the pressure acting on this diaphragm tends to move a piston assembly 52, 48, 46 leftwardly, as seen in the drawing. This serves to displace diaphragm 32 from an annular flange 24 and so open chamber 23 to the piston assembly containing chamber 20, the latter being vented to drain by an opening 18. Similar venting is obtained in the event of diaphragm rupture or leakage between a seating member and its associated diaphragm. Modifications of the above embodiment are depicted in Figs. 3 to 6, not shown.

Filed: 1944-09-04
Abstract: 606,111. Valve generating circuits. BRITISH THOMSON-HQUSTON CO., Ltd. (General Electric Co.). Sept. 4, 1944, No. 16839. [Class 40 (vi)] A crystal-controlled valve oscillator having an oscillatory circuit between the anode and cathode and the crystal connected between one of the other electrodes and the cathode utilizes the rectified high-frequency oscillations derived wholly from the control electrode to which the crystal is connected to maintain the potential of another electrode such as to oppose any changes in output voltage. The Figure shows a pentode oscillator 10 which has crystal 16 in the grid cathode circuit and a tuned circuit 19, 20 connected to the anode. Oscillations, which are due to feedback through the anode-grid capacity, cause grid current to flow in potentiometer 26 to produce a voltage, part of which is applied to suppressor grid 15. An increase in oscillation amplitude produces a larger potential across 26 and a larger negative voltage is thus applied to suppressor grid. Automatic output voltage regulation is thereby obtained. Specification 498,807 is referred to.

Abstract: 425,808. Carving and shaping wood. JENSEN, M. H., 10, Jernbanegade, Kallundborg, Denmark. June 7, 1934, No. 16884. [Class 145 (i)] In a machine for producing the hull of a toy vessel or other similar articles of wood, the work and model are carried by a frame having three individual straightline motions which are mutually at right angles whilst the tracer and the cutter are supported on a stationary frame. The stationary frame 22 supports a tracer 23 and a rotary cutter 24 the ends respectively of which 37 and 36 are disposed opposite to the model 19 and the block 20 to be modelled. These two are carried by a frame 14 which is balanced by a weight 18 and which is movable vertically on a frame 12 by means of a lever 26. The frame 12 is movable horizontally on guides 30 by means of lever 35. Guides 30 are carried in turn by a frame, the legs 11 of which are movable on guide rods 4. To produce motion of this frame a shaft 5 is screwed and acts upon a nut in the frame and this shaft is rotated by a friction disc 6 in contact with a disc 10 driven by any suitable source of power. To produce forward or reverse action the disc 6 is moved across the disc 10 by either a hand lever 7 or pedal 54. Instead of operating upon a solid block, the block may be built up of parts having an approximate outline to that finally required and such block may be secured to the carrier 14 by an intermediate fitting. For modelling the interior 53 of the block, the preformed outer surface is held between half blocks 51 and the model is similarly supported.

Filed: 1916-11-27
Abstract: 111,174. Kersting, C. B., and Dungey, J. W. Nov. 27, 1916. Intercommunication apparatus.-An electric selector for intercommunication telephone systems comprises a number of turn-keys B mounted upon spindles A which carry at their other ends contact-members C normally held against the stops F by springs SP. When one of the keys is turned it first lifts a conducting locking-bar D thereby releasing any other key already in the operative position and locked there by the engagement of the nose J of the locking-piece with the upturned end of the contact-piece. Further turning of the key brings the end of the contact-piece into engagement with a fixed contact bar E and completes the ringing circuit of the station corresponding to the key. This movement of the contact-piece also brings its upturned end into engagement with the cam-shaped undersurface H of the locking-bar which is consequently raised, considerably, to ensure the release of any previously operated key not liberated by the first part of the movement. When the hand is removed from the key, the contact-piece moves back slightly and is engaged by the conducting nose of the locking-bar thereby completing the listening circuit of the particular key operated. All the keys are returned to the off position by the movement of the switch hook when the receiver in replaced.
