Title: Improvements in extensible tables
IPC: A47B1/03
Filed: 1925-06-30
Abstract: 244,349. Brettell, F. G., (Seng Co.). June 30, 1925. Expanding tables have leaves folding under the top when not required and inserted between separate parts of the extended table. Each extension leaf is in two parts 6 hinged at 7 and is connected by link 13 pivoted to the under side of one part 6 and to the frame; a rotatable strut 16 is moved by the link to a supporting position near the centre of the extended leaf. The link 13 is substantially U-shaped and has a crank portion 15 between its pivots 12a on the table frame, a strap member 18 connecting the portion 15 and strut 16 for simultaneous action. The brackets 12<a> by which the link is pivoted allow slight lateral motion for the engagement of dowel pins in the table leaves. In a modification shown in Fig. 4, the crank portion 23 is bent out of the plane of the link 21 and sinks when collapsed in a recess in the table bottom and supports the extension leaf when in use. The table may carry a drawer, into which the extension leaf may fold.

Title: Improvements in or relating to Screening or Sifting Devices.
IPC: B07B1/34
Filed: 1917-11-15
Abstract: 120,628. Bell, W. J., and Tyler Co., W. S. Nov. 15, 1917. Fixed sieves.-One or more stationary screens provided with means for vibrating the cloth and for stretching it by expansion of the screen frame to which it is attached are mounted at an inclination in the box 21. The screen frames consist of side angle-bars 35 and end angle-bars 36 connected by gusset-plates riveted to the angle-bars. One set of the rivet holes in the gusset plates are enlarged to allow of the frame members being moved apart; this is effected by screwed rods 42 passing through nuts 43 fixed to the side bars and having squared ends 44. The end bars 36 are connected by screwed rods 40. Inclined pegs 45 project from the top surfaces of the side and end bars and the ends of the screen cloth have secured to them clips 50 formed with holes to take over the pegs on the end bars, while to the sides of the cloth are secured metal strips that are perforated to engage over the pegs on the side bars. Deflectors 55, Fig. 12, secured -to the sides of the box and provided with packing strips 56 bearing upon the cloth, prevent the escape of material over the edges of the screen. Metal strips 52 secured along the centre of the cloth carry the sockets 53 of posts 64 adapted to receive the impact of the vibrating-device. The posts pass through packed openings in the cover 25 of the box. The cover is hinged at its upper end and carries two shafts provided with pulleys, and, by means of a central support 57, .a spring blade 58. The blade is flexed by means of eccentrics on the shafts and carries at its free ends adjustable hammers 59 which strike the free ends of the posts 64. The posts of the lower screen bear upon the under surface' of the upper screen. The screen box is provided with inspection doors 82, 83<1>, and is supported by pillars 28 which engage by screws of opposite hand with lugs on the box and with foot sockets 30, so that their length may be adjusted by turning them. The sockets 30 are adjustably connected by bars 31 to brackets 27 in which the lower end of the box is pivoted.

Abstract: 1461641 Wells &c BAKER OIL TOOLS INC 18 April 1974 [15 June 1973] 16914/74 Heading E1F A subsurface shut-off valve for insertion in production tubing T comprises a valve member 46 moved by the pressure of control fluid, the member including a by pass valve 86, 87 for equalizing the well pressure over the member before it is moved from valve closed position to valve open position. The member is carried by pivots 75 on arms 74 depending from a piston sleeve 67, the arms having a ring 51a engaged by a spring 51 which, in conjunction with the wall pressure on the sleeve, biasses the member and sleeve upwardly within the valve casing 20 to close the valve. The member has operating slots 45 which: coact with pins 44 carried by arms 43 of a cage 40 located by shoulders 36, 37 in the casing. The member has a cap 85 rotatable with, but having limited radial movement relative to, the body of the member. Control fluid supplied to a chamber 79 moves the sleeve 67 downwardly, the initial movement of the sleeve displacing the body of the member to the position shown in Fig. 3b to open the bypass valve, and the rest of the movement of the sleeve entraining a seal sleeve 60 so that the displaced body and cap are rotated by the pins to open the valve. The valve may be opened manually by using a shifting tool to force a sleeve 63 downwardly, the sleeve 63 moving the sleeve 60 and the valve being held open by a ratchet 63b.

Title: Improvements in and relating to electrical meters
IPC: G01R1/36
Filed: 1937-06-22
Abstract: 495,890. Current and pressure meters; variable resistances. SOMERVILLE, T. B., ALLIBONE, T. E., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. June 22, 1937, No. 17392. [Class 37] An ammeter or voltmeter of the kind responsive to current flow therethrough is shunted by a resistor element formed of non-linear resistance material, the voltage V applied to and the current I flowing through the resistor being connected by the equation V = kI<B> where k is a constant and the index B has a value less than 0À4. The non-linear shunt resistor is arranged to pass a very small current for the normal ranges of the meter but becomes highly conducting and therefore protects the meter when excess voltage or current is applied thereto. In view of the non-linearity of the resistor the meter scale is more open at the lower part thereof and may therefore be calibrated to a smaller scale at the upper end, for example, an ammeter may indicate microamps and milliamps respectively at the lower and higher parts of the scale. In the case of a voltmeter the non-linear shunt 5 may be connected directly across the meter 1, or, as shown, it may be connected to a variable tapping 7 on the usual series resistance 2. Also, a normal linear resistance 6 may be connected in series with the shunt 5, according to the regulating effects desired, i.e. whether the shunt is fitted primarily for varying the scale or for protective purposes. The non- linear resistance element 5 may be housed in the meter casing or in the series box in the case of a multi-range voltmeter. The non-linear resistance material is preferably that sold under the Registered Trade Mark " Metrosil " and comprises a composition of ball clay, carborundum and graphite or similar substances mixed together, pressed into the required shape and fired so that the resulting body is of a ceramic nature. Terminal leads may be readily connected by soldering them to an adherent coating of zinc or other metal sprayed upon the resistor. The resistor shunt 5 is preferably formed of a plurality of discs 21, Fig. 6, of the non-linear resistance material, mounted on an insulating sleeve 27 between pressure plates 23 tightened by nuts 24 on a bolt 22, the discs 21 being separated by conducting plates 25, 26 whereby they may be connected in series, parallel or series-parallel according to the regulating effect desired.

Abstract: 963,473. Drying in electric fields. UNILEVER Ltd. July 20, 1960 [May 21, 1959], No. 17398/59. Heading F4G. [Also in Divisions A2 and H5] A foodstuff is dried in a substantially uncompressed state by exposing it under low pressure and at a temperature above the freezing point of water to microwaves of wavelength from 3 to 50 cm., preferably from 10 to 35 cm., which are supplied at such intensity that water present in the foodstuff is rapidly vaporized therefrom, the water vapour thus generated being continuously removed. Food is dried within a glass flask 4 permeable to microwave energy and mounted on a polytetrafluoroethylene trolley 5 movable on rails 6 within a microwave oven 1 coupled to a magnetron by a waveguide 2. The neck of the flask is connected through flexible pressure tubing 8 to a rotary vacuum pump 10 by way of condensers 12, 13. During drying the trolley is moved slowly to and fro on the rails to improve the uniformity of absorption of the microwave energy and overheating of the food is avoided by the provision of flowing water through a tube 16 in the oven whereby the proportion of microwave energy absorbed by the water in the tube increases continuously as the food loses its water.
