Filed: 1936-08-26
Abstract: 472,444. Door-operating appliances. BAERT, G. Aug. 26, 1936, No. 23418. Convention date, Aug. 20, 1936. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 1, 1937.] [Class 65 (i)] A spring - closing and fluid - check device for doors comprises a piston 5 sliding in a casing and a rotatable shaft 24 passing through the centre of the piston and formec with two pairs of part-helical grooves 13, 14 which engage balls 11, 12 carriec by the piston so thai rotation of the shaft (by a lever fixed tc its upper end) causes sliding of the piston ; two helical springs 16 are compressed by the piston during the opening movement of the door. The piston is prevented from rotating in the casing by balls 7 engaging vertical grooves in the wall of the casing. The piston is provided with a ball check valve 23, and the fluid above the piston is forced, during the closing of the door, through an aperture 20, controlled by a screw-valve, into a passage 21 in the casing leading to a central recess in the piston, from which it is discharged through an aperture 22 in the piston. The Specification as open to inspection under Sect. 91 describes also a linkage for operation of the device, but its action is not clear. This subject-matter does not appear in the Specification as accepted.

The cylinder is fitted with a cock i and a connection h for a pressure gauge. The humidity is determined from the alteration of pressure after the cylinder has been tilted several times so that the piston passes from end to end and complete absorption of the water vapour has been effected.

Abstract: 678,222. Gas cooking stoves. MAIN, Ltd., R. & A. Oct. 24, 1950 [Sept. 12, 1949], No. 23549/49. Class 126 A gas oven has a single burner across the bottom and an outlet for the products of combustion at the top and front of the oven and an auxiliary outlet nearer or at the back of the oven. The oven is heated by a burner 10 extending across the bottom of the back wall 11. A proportion of the waste gases escape through an outlet 12 in the top wall of the oven into a flue passage 14 extending between the upper wall of the oven and the bottom wall 20 of the grill chamber. An opening in the top of flue 14 co-operates with an upwardly extending tapered flue passage 17 leading to an opening in the cooker hot-plate. Additional openings 21 in the top wall of the oven also lead to the shallow flue 14. Further openings 23, spaced apart across the top of the back wall 11 communicate with a duct 24 leading into flue passage 14. The openings 21 in the top wall may be dispensed with, and the openings 23 in the back wall may lead to a duct extending out through the cooker casing, Fig. 2 (not shown). In a modification, Fig. 3, (not shown), the additional openings in the top or back wall of the oven are replaced or supplemented by openings in the side walls near the back, which communicate with ducts leading to the shallow top flue. Alternatively or additionally openings in the side walls may lead to a duct extending out through the casing. Specification 606,576 is referred to.

Title: Improvements in or relating to Three-Point Safety Seat Belts for Motor Cars
IPC: B60R22/38
Filed: 1967-05-22
Abstract: 1,172,144. Safety harness. G. E. Y. PATENTER A.G. 22 May, 1967 [27 May, 1966], No. 23717/67. Heading A3V. A three point safety belt has one strap, preferably the chest strap 10, mounted on a spring retraction reel 19 and the other strap 11 mounted on a slide plate 26 guided in the reel housing on a headed nin 26 and urged by a spring 28 in a direction to keep a pawl 24 carried by the plate out of engagement with a ratchet wheel 21 on the reel. The chest and lap straps may be one continuous strap passing through a slotted anchor plate (12), Fig. 1 (not shown). The spring reel allows controlled movements of the upper part of the user's body but under heavy deceleration as in a crash tension in the lap strap causes the pawl 24 to move to reel-locking position before the chest strap can unwind. Friction at the slot in the anchor plate prevents the pull being transmitted via the chest strap to the reel before the reel has been locked. In an alternative embodiment the spring 28 is so weak that the pawl 24 is normally in engagement with the ratchet wheel and for the user to have freedom of motion he must reduce tension in the lap belt by pulling in his diaphragm and restrain the chest strap from retracting so that the spring 28 can pull the pawl out of engagement with the ratchet wheel. In a further embodiment in which the chest and lap strap are integral the lap strap is mounted on the reel and the chest strap is connected to the slide plate. To lengthen the straps the user must reduce the tension in the chest strap to allow the spring 28 to disengage the pawl from the ratchet wheel; the lap strap can then be unwound from the reel and the lap and chest strap portions adjusted by means of the slotted plate 12.
