Title: Production of neutral esters of orthophosphoric acid
IPC: C07F9/09
Filed: 1953-07-21
Abstract: Neutral esters of orthophosphoric acid are obtained by treating triesters of phosphorous acid with aqueous solutions of metal salts of hypochlorous acid.  The esters of phosphorous acid may be aliphatic or aromatic and the reaction may be carried out at room temperature or lower temperature, preferably in a continuous manner. In examples (1) tri(b -chloroethyl) phosphite is added gradually to 4.8N sodium hypochlorite solution containing sodium hydroxide in a concentration of 0.2N, the temperature being kept at 0-10 DEG  C. by external cooling.  The reaction is completed at room temperature and the oil formed is separated from the aqueous layer and dried and distilled to yield tri(b -chloroethyl)phosphate; (2) tricresyl phosphite (prepared from cresol and phosphorus trichloride) and 4.8N sodium hypochlorite solution are simultaneously and continuously introduced into an iron reaction vessel, the temperature being maintained at 45-50 DEG  C.  The effluent from the reaction vessel is passed through one or two further reaction vessels and then allowed to settle to separate the oily layer from which tricresyl phosphate is recovered.

Screw-threaded articles, e.g. caps, couplings and nuts, are made in an injection moulding machine comprising a rotatable core 12, an ejector plate 35 and a stationary female mould 11 by a series of operations, starting from the closed state of the mould shown, which are as follows (1) Material is injected from nozzle 2<SP>1</SP> to fill cavity 11<SP>1</SP> and surround the screw-threaded end of core 12 and is cooled. (2) Motor 23 is operated to rotate shaft 28 and thereby a screw control member 29 and core 12, these components having the same pitch, such that a block 34 threaded on member 29 and carrying a plate 37 is urged forwardly. This forwards movement is translated into a rearwards movement of main housing 21 and its associated parts by the thrust of rods 36 on ejector plate 35. (3) A piston 20 is subjected to hydraulic pressure within cylinder 19 to move housing 21 rearwardly and strip the article from mould 11, Fig. 3 (not shown), core 12 continuing to rotate and ejector plate 35 to move forwardly until the article is stripped from core 12, Fig. 4 (not shown). (4) Motor 23 is reversed and piston 20 is moved forwardly until the initial closed state of the mould is attained; ejector plate 35 is brought into contact with rods 36 when the plate contacts mould 11 and is caused to slide rearwardly on pins 40. In a second embodiment, Figs. 5a and 5b (not shown), a plurality of articles are simultaneously formed, a gear-box (41) being situated between screw control member 29 and a plurality of cores (12A). In a third embodiment, Figs. 6-8 (not shown), an article having a plurality of screwthreads is formed. Furthermore, motor (23B) is positioned coaxially of screw control member (29B) and rotation of the latter within a socket (104) causes retraction of cores (12B), ejector plate (35B) being held by bearings (107). Subsequently piston (20B) is moved rearwardly and the article is stripped from the cores, Figs. 7 and 8 (not shown). In a fourth embodiment, Figs. 9-11 (not shown), the action of ejector plate (35C), which receives a thrust from rods (36C), is similar to that described in the first embodiment, but the action of piston 20 is replaced by reciprocating rods (201). Moulding materials mentioned are vinyl chloride, cellulose acetate, polyethylene, polystyrene, methacrylic resins, polycarbonates and nylon.

Abstract: 1362309 Vehicle seats ISRINGHAUSEN Gebr 4 May 1972 [12 May 1971] 20769/72 Heading A4U A vehicle seat, in which the resilience of the seat mounting is automatically adjusted by an occupant to suit his weight irrespective of what his weight may be, comprises a seat part 1, connected by parallel levers 2, 3 to a fixed support 4, and a spring 13, the position and hence the torque lever arm of the spring being altered to suit the occupant's weight by a correcting element operated by a reversible servomotor 19 which is started by operation of an actuation switch 20 by the seated occupant. The motor 19 is stopped by operation of a limit switch 21, mounted on an angular arm 6 forming an extension of the lever 2 beyond a swivel axis 5, by an actuating element 22 mounted on the support 4. The motor 19 is operatively connected by a shaft 17, passing through the support 4, to a spindle 10 of the correcting element, which also includes an internally threaded rod 9 which is moved along the spindle 10, guided by a slot 8 in the arm 6, when the spindle is rotated, the rod being connected by a cover plate 11 to an end of the spring 13. A travel-reversing switch 26 is provided at each end of the slot 8 for contact by the cover plate 11. During vibration of the seat when the user seats himself a contact cam of the limit switch 21 is led along the actuating element 22 until it is arrested by a recess 23 in the element and disconnects the supply circuit to the motor 19. Since the torque of the spring has been altered to suit the static load of an occupant's weight, the actuating element can be fixed to the support and the position of the recess corresponds to the optimum adjustment for the user's weight no matter what that weight may be. Slots 24 in the actuating element 22 allow adjustment of the position of the element within a range so that individual requirements for a soft or hard ride can be catered for. A damper 7 is connected between the levers 2 and the support 4. In a modification the spring surrounds the damper which is connected between the seat part and a cross-bar which is movable lengthwise of slots in a U-bracket, secured to the fixed support, by a spindle rotated by the servomotor, the limit switch being mounted, preferably adjustably, on the fixed support, the actuating element being mounted on the lower parallel link, and an actuation switch for operation of the motor in each direction being provided, the two switches being of different sizes so that they can be distinguished, and a mechanical or electrical inter-locking device to prevent simultaneous operation being included.

[Class 44] [Also in Group X] A one-piece metal fastener for securing a trim panel in position, and particularly for securing such a panel to a door or other part of a vehicle body, comprises a portion 13 adapted to fit into an aperture 27 provided in the foundation sheet 23 of the panel, an abutment 14, 16 attached to such portion at each end for engaging the sides of the aperture, a tongue 21 cut out from one abutment 16 and adapted to underlie the foundation sheet, and a spring gripping-member 17 which is formed as an extension of the said abutment 16 and is adapted to extend away from the aperture and to overlie the sheet. The panel, which is shown in Fig. 4 as applied to the flanged portion 12 of a door frame 11 having an outer metal panel 10, may comprise a foundation sheet 23 of fibreboard, a padding 24 of compressed jute or other fibrous material, and a fabric covering 25 which is folded around the edges of the sheet 23 and cemented thereto. The body portion 13 of the fastener is adapted to fit into one of a series of rectangular apertures 27 provided along the side and bottom edges of the sheet 23, and is formed at its rear end with the abutment 14 and a flange 15, and at its front end with the abutment 16 which is extended to provide a spring bow 17, a curved gripping portion 19, and an upward end portion 20. The projection 21, which is stuck out from the abutment 16, lies in the plane of the base 13. The fastener is assembled in an aperture 27 by first inserting the projection 21 into the aperture so as to extend beneath, and underlap, the forward edge of the aperture. The rear end of the fastener is then forced down into a position in which the abutments 14, 16 engage tightly the rear and front edges of the aperture. The front corners 21a of the tongues 21 are bent up, so as to become embedded in the underface of the sheet 23. In applying the panel to a door frame, the fasteners on one edge of the panel are forced over the flange 12 on one side of the frame, the panel is then bowed to permit the fasteners along the opposite edge of the panel to be engaged with the corresponding frame member, and the panel is then forced downwardly to enable the fasteners along the lower edge of the panel to engage the adjacent frame member.
