Title: Improvements in or relating to apparatus for degreasing by means of volatile solvents
IPC: C23G5/04
Filed: 1935-05-16
Abstract: <PICT:0456821/III/1> An apparatus for degreasing metal and similar articles by solvents consists in a unitary structure, the combination of a number of interconnected degreasing compartments and a solvent vaporizing compartment which receives impure liquid solvent from a degreasing compartment and the vapours are condensed in a vapour space common to the degreasing and vaporizing compartments.  A tank 1 is divided by vertical partitions 2 to form degreasing compartments 26, 27, 28 and a vaporizing compartment 24.  The compartments containing solvent are heated by gas burners 10 and are provided with inclined non-perforated plates 8 and perforated platforms 7. Solvent flows from clean solvent compartment 28 through perforations in the partition 2 and downwards through a channel formed by a partition 6 to the bottom of the solvent compartment 27.  Swirling or eddies are formed by the plate 8 whereby solid particles are carried with the solvent over into the vaporizing compartment.  The used solvent flows from the upper part of the compartment 26 into the compartment 24 where the solvent is instantaneously vaporized.  The vapours are condensed by cooling coils 3 and is collected in a gutter 5 communicating with the clean solvent compartment 28 through a pipe 25.  The exterior wall of the vaporizing compartment 24 is inclined inwards whereby area of the tank exposed to the atmosphere is reduced.  The metal goods to be cleaned are treated first in the compartment 26, then in 27, and finally in 28.  They are then transferred to a heated drying chamber 12 provided with cooling coils 23.  Vaporized solvent condenses and is collected by a trough 14 communicating with the sump 20.  At intervals solvent is drawn off through a cock 21 and returns to the degreasing apparatus.

Filed: 1961-04-21
Abstract: 1,023,582. Amplitude modulators; transistor amplifier circuits; automatic gain control. PLESSEY CO. Ltd. June 29, 1962 [April 21, 1961], No. 14451/61. Headings H3R and H3T. A modulator comprises a three-limb magnetic core respectively having a carrier input and an output winding and a modulation winding controlling the magnetic reluctance of the third limb acting as a magnetic shunt to the input winding flux and varying the carrier flux through the output winding. Further, the modulation winding is connected across the collectors of a pair of transistors, the modulation being applied between the emitters and the bases each connected together in common, and has a centre tap connected to the emitters. The carrier voltages induced across the two halves of the modulation windings ensure that each transistor collector is at negative voltage alternately (and hence each transistor conductive alternately). In a modification two such three limb cores are used, each core operative alternatively in accordance with the polarity of a modulation input (D.C. or A.C.) applied in opposite phases between the emitters and bases of two pairs of transistors. The outputs of each core are rectified and differentially combined to give an amplified output (D.C. or A.C.) corresponding to the polarity or phase sense of the modulation input. The carrier inputs may be derived from a transistor oscillator using inductively connected feedback windings on the two cores. Alternatively a symmetrical transistor may replace each pair of transistors. The modulator carrier input may itself be initially modulated and further modulated by a D.C. modulation signal, and this used for automatic gain control.

Title: Improvements in or relating to structural materials containing bonded wood particles
Inventor: BIRD FRANK
IPC: B27N3/14
Filed: 1956-05-09
Abstract: A structural material comprises a mass of wood particles adhesively bonded together in the form of a sheet which is contoured on one or both faces to provide a regularly repeating pattern of zones of reduced thickness, the wood particles being distributed so that the specific gravity of the sheet is substantially greater in said zones than in the portions of sheet therebetween.  Preferably the weight per unit area of the sheet is substantially uniform, and the zones are located at the bases of depressions having sloping walls from the tops to the bottoms of which the specific gravity of the sheet increases.  The wood particles may be wood chips or sawdust and the adhesive may be of urea-formaldehyde, phenol-formaldehyde, or an epoxy resin.  The zones are distributed in an array of any desired geometrical form, preferably in a rectangle, e.g. a square, and the portions of sheet between the zones are preferably of uniform width. In one example a layer of a mixture of wood chips and urea formaldehyde resin glue containing ammonium chloride or an acidic hardening agent is spread on a flat heated platen, and the lower part of the layer confined within a metal frame.  Above the layer is then placed a metal plate having the pattern required to produce a surface having frusto pyramidal depressions of square tops and bottoms, and which are centred at the intersections of two mutually perpendicular sets of parallel equally spaced lines.  The whole is then pressed at 80 to 100 p.s.i. for 6 minutes at 130 DEG  C. Alternatively the heated platen may be provided with a pattern so that the product has depressions on both of its faces in coincident or different positions.  In a further example the manufacture of a sheet having corrugated surfaces is described.ALSO:In one method of moulding a sheet of wood substitute contoured on one face to provide a regularly repeating pattern of zones of reduced thickness and increased specific gravity (see Group V) a layer of a mixture of wood chips and urea formaldehyde resin binder containing ammonium chloride or an acidic hardening agent is spread on a flat heated platen, and the lower part of the layer confined within a metal frame.

Abstract: 857,813. Camera attachments. INTERNATIONAL POLAROID CORPORATION. May 1, 1959 [May 13, 1958], No. 14982/59. Class 98(1) A camera attachment comprises a housing having an aperture for aligning with the camera lens and a shutter to open and close this aperture, also means for varying the aperture exposure and an actuator for moving a member for locking the attachment to the camera, a member for moving the camera shutter mechanism into the bulb exposure position and another member to move an actuator on the camera to keep the camera shutter open. As shown, a well 82 of variable size on the attachment fits over the lens collar of the camera and projection 98 fits into a slot suitably arranged on the camera. A lever 88 adjusts the position of projection 108 on an arm 104, which is pivoted at 102, through cam surface 90 and cam follower 106 so that when lever 88 is moved from left to right in Fig. 5, projection 108 moves through slots in the attachment housing and in the camera thereby locking the attachment to the camera with aperture 60 coaxial with the camera lens. The attachment also comprises a blade 200 (Fig. 6) with an aperture 204 which moves in front of apertures 60 during exposure. By pressing handle 64 downwards arm 216 moves the shutter clockwise about a pivot 202 and an auxiliary shutter 222 fixed to arm 216 prevents an exposure being made until blade 200 returns to its initial position under action of spring 210. The exposure time is controlled by an exposure meter 56 which adjusts the valve 236 of bellows 230 which are used in known manner to control the exposure time. In order to ensure that the camera shutter is open during these operations movement of lever 88 to the right in Fig. 5 (a) rotates the cam surface 134, which is adapted to adjust the camera shutter mechanism to the bulb exposure position and (b) rotates cam surface 94 and hence arm 116 so that the end 126 of this arm moves the camera shutter adjustment knob and opens said shutter. When lever 88 is on the left in Fig. 5 projection 124 abuts projection 72 and prevents the actuating knob from being depressed. Specifications 677,314, 685,685, 857,410 and U.S.A.
