Title: Coupling device for interconnecting chairs and similar seating furniture in a row
IPC: A47C1/124
Filed: 1954-04-07
Abstract: 752,483. Connecting seats &c. in rows. KRUIJT, W. J. April 7, 1954, No. 10269/54. Class 52(2). [Also in Group XXV] Like chairs are connected in a row by the engagement of a pawl on one chair with a catch on the adjacent chair, the release of a catch allowing it to move under spring influence to move the pawl on the same chair which releases the next catch and so on down the row. In figs. 1 and 3, a catch 4, underneath the seat of a chair 2 is swung through 180 degrees, against the action of a spring 8 on a horizontal shaft 6 by the turning of a key 7 to rest in slots 9 so that a transverse bar 10 on the catch 4 engages with the nose of a pawl 5 pivoted on an adjacent chair 1. The row of chairs is connected together in this manner. In the first chair 1 of the row an abutment 11 prevents the catch 4, under the action of its spring 8, pushing the pawl 5 upward against a rubber block 16 to the release position. The withdrawal of the abutment 11 by the action of a leaf spring 12, after rotation of the catch anticlockwise to free the abutment, will allow this and hence cause the progressive releasing of the catches 4 in the row. In a modification, fig. 4 (not shown), the catch 4 is longitudinally slidable between two chairs. In a further embodiment, Fig. 6, a catch 4 is swung through 180 degrees on a horizontal shaft 6, against the action of a spiral spring, to engage with a pawl 5 of an adjacent chair. A fixed projection 16<SP>1</SP> of said adjacent chair enters an opening 17 of the catch 4. Three pawls 5 side by side are used. Release of the catch will allow it to rotate back under the seat due to its spring and cause a U-shaped bar 18, eccentrically pivoted to the catch 4, to push the tail 19 of the paw] 5 to release the next catch 4 and so on down the row. However, if a small plate 11 on the first chair, rotable about a horizontal shaft 21 by a handle 22, is swung round to force the bar 18 down, the pawl 5 is not raised and engages the catch of the second seat for interconnection. Fixed pins 20 prevent unauthorized lifting of the bars 18 in the rest of the chairs of the row. The plate 11 has a projection 23 which extends between the limbs of the bar 18 and engages in the opening 17 of the catch 4. For release, the first shaft 6 is turned by a key which releases the projection 23 from the opening 17; the plate 11 rotates upward under the weight of the handle 22 and the successive release of the row of chairs follows. The bars 18 are adaptable to different widths of chairs.

Title: Improvements in hydraulic control valves
IPC: B23Q5/26
Filed: 1945-04-24
Abstract: 614,310. Rotary valves. PADDON, W. April 24, 1945, No. 10298. [Class 135] A hydraulic control valve for regulating the feed of machine tools comprises a rotary disc or like member 8 with a circular series of metering orifices 9 of progressively differing crosssectional area held in engagement with a sealing washer 10 in the end of a cylindrical bore 1 in the valve casing by a spring 17a. The bore has a lateral inlet 18 communicating with a second bore 2 containing a filter 3 of wire gauze which can be renewed by removing a screw plug 4. The bore 1 also has an outlet 7 coinciding with apertures 12, 13 in the washer 10 and a further washer 11 respectively, the desired metering orifice 9 being brought into register with these apertures by the rotation of a spindle 14 passing through a gland or cover 15 and carrying a hand wheel 16 with peripheral markings read in conjunction with a fixed pointer 17. A spring-pressed locating ball or pin may engage notches in the edge of the valve disc. As applied to the cutter of a cylinder boring machine, the outlet 7 is connected to a sump and the inlet 6 of the bore 2 is connected to a cylinder containing a ram or piston which supports the cutter head. The hydraulic control valve may thus be set to control the rate of leak from the column of liquid supporting the cutter head. In a modification, the bore 2 is dispensed with and the filter is arranged in the bore 1 behind the washer 11. In a further modification, the washers and the valve member are conical.

Title: Combined luminescent screen and anti-diffusion grid and method of making same
IPC: G21K4/00
Filed: 1970-03-04
Abstract: 1299664 Luminescent screens OPTISCHE INDUSTRIE "DE OUDE DELFT" NV 4 March 1970 [5 March 1969] 10400/70 Heading C4S [Also in Division H5] A combined X-ray luminescent and antidiffusion screen comprises a number of compartments containing luminescent material separated one from another by light reflecting walls the major surfaces of which extend parallel to the primary X-rays, the walls being formed of spaced apart strips of X-ray absorbent material, e.g. thin matallic strips 1, the compartments being filled with luminescent material 3 over a part of their height on the side remote from the X-ray source and for the remainder of their height, being transparent to X-rays (e.g. solid strips 2). Preferably the material of solid strips 2 is also light reflective, e.g. white. The screen inherently functions as an X-ray antidiffusion grid and the ratio of the remainder of the height to the spacing distance between adjacent strips (e.g. 0À3 to 1 mm.) is preferably greater than three. In a method of fabrication the grid of spaced strips may be placed one side in a layer of soluble material (e.g. paraffin wax and petroleum jelly mixture) of thickness equal to the luminescent layer to be formed, filling the remainder of the compartments with a selfhardening liquid (e.g. a thermosetting plastic such as an epoxy resin with a white pigment), removing the soluble material with a solvent such as petrol, and filling with luminescent material. A curved surface (18) spherical or cylindrical, may be used (Fig. 7, not shown) and the screen pressed to flatness before the selfhardening liquid solidifies to ensure direction of the strips to the X-ray focus. Fig. 8 (not shown). Protecting cover (23) and edge (20) may be provided. The screen may be circular (Fig. 2, not shown) spaced by corrugated or waved strip (5) with compartments (7), or flat (Fig. 3, not shown), the corrugated strips (16) of Fig. 4 (not shown) being filled with phosphor (13) over only a small portion of their height, and retained by p.v.a. layer (15), material (14) being highly X-ray transparent, a thin layer of same protecting the upper edges. In Fig. 5 (not shown), corrugated strips (16) are the full screen height, and in Fig. 6 (not shown), only the phosphor height, spaces (12<SP>1</SP>) being X-ray transparent. The walls of Fig. 2 may be focus aligned by pressing the outer strip during winding by a roller on a rod journalled at a point on the optical axis. The flat strips at least should have a high absorbtion for secondary X-rays, especially high A. Wt. metals of high specific absorbtion. 0À03 to 0À04 mm. Au and Ag are instanced. In Figs 4 and 5 for example, heavy flat strips and lighter waved strips may be used, and may be an alloy of light and heavy metals or a stratified combination of different materials. A medical X-ray image intensifier camera may include a 0À6 to 0À7 mm. thick phosphor layer. Reference is included to Specification 777,745.

Abstract: 913,819. Unloading heaped materials; screw conveyers. C.U.R.A. PATENTS Ltd. June 21, 1961 [March 24, 1960], No. 10554/60. Classes 78 (1) and 78 (4). The material in a heap 51 such as a pile of coal situated on the ground or in a bunker, is removed, e.g. to a pit 50 adjacent the heap, by apparatus comprising a pair of parallel unenclosed conveyer screws 43, 44 of opposite hand which are traversable together through or across the heap transversely of their length and have a common drive means to rotate them both simultaneously in the same sense. The traversing is effected by pivoting of the assembly 47 about a vertical axis at O, which assembly houses the drive means and rotatably supports the screws 43, 44. In use, the screws are brought to the position OX in which the screw 43 touches the pile. Both screws are then rotated, their opposite travel producing, by the screws' engagement with the material of the pile, a torque which rotates the assembly about the vertical axis at O to sweep through the pile as shown (Fig. 1) with the leading screw 43 feeding material to the pit 50. At position OY the drive means is reversed and the assembly returns toward OX with screw 44 feeding into the pit. The assembly 47 may also be pivoted about a horizontal axis 49 (Fig. 1) perpendicular both to the vertical axis at O and to the screws, so that the latter may ride over the heap instead of passing through it as shown.

Abstract: 736,900. Photographic cameras. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 20, 1953 [April 23, 1952], No. 10744/53. Class 98 (1). A photographic camera comprises a viewfinder in a housing which also contains one or more graduations indicating the position of a camera control or controls, and a light source for illuminating the graduations. The light source may be in series with a switch so that a flash-bulb circuit may be tested. As shown the viewfinder lenses 1, 2 are mounted in a housing (not shown) of which lens 1 is mounted in the back wall and a limiting frame 3 is mounted in the front wall. A pointer 10, coupled to the focusing mechanism of the camera, moves over a distance scale 9, and a disc 11 bearing numbers indicating the number of exposures made is geared to the film winding mechanism and observed by means of a mirror 13 and lens 2. A flash-bulb 5 is connected to be fired by a battery 6 when a switch 7 (e.g.) in the camera shutter is closed. Switch 7 is shunted by a switch 8 and a lamp 4. The resistance of lamp 4 is such that the current passing through the flash-bulb when switch 8 is closed does not fire the flash-bulb, but causes lamp 4 to light. Lamp 4 is mounted at the side of the view-finder casing to illuminate scale 9 and disc 11. Scales showing diaphragm opening and shutter speed may be similarly illumminated.

An article, e.g. a rolling diaphragm, is moulded by applying a sealant 3 to a reticulated fabric layer 2, at least in an area of angular shape, placing this in contact with a plastic layer 1 and pressing them together using dies 4 and 5. The sealant 3 is compatible with the plastic component 1 and occupies the spaces of the fabric layer 2 to limit penetration of the plastic component when pressure is applied. The requisite properties of a sealant are that it should be liquifiable, flexible when dry and adhere to the fabric and plastic component, but not to the dies 4, 5, withstand necessary temperatures, not soften when moulded allowing the fabric to be penetrated by the material of the plastic component, and have no harmful effect on the two components. Two examples of sealants are carboxyl modified butadiene acrylonitrile latex, and butadiene acrylonitrile copolymer synthetic rubber suitably compounded and made into a solution in an organic solvent. The plastic component may be rubber, synthetic rubber or rubber substitute.
