IPC: E05B65/20
Filed: 1966-08-17
Abstract: 1,162,251. Latches. L. W. MENZIMER. 17 Aug., 1966 [21 April, 1966], No. 36784/66. Heading E2A. A vehicle door latch 15 comprises a base plate 24, a latching element 17 mounted on the base plate, a pawl 32 for holding the latching element in the latched position with a striker 18 on the vehicle, an operating member 40 movable from a first to a second position, a transfer member 46 connecting the operating member and the pawl for releasing the pawl when the operating member is moved to the second position, a locking member 51, serving When set to a looked position to prevent the transfer member 46 from releasing the pawl, and a cancellation member 65 independently supported on the base plate at a point remote from the latching element 17 and from the locking member 51 and serving to cause the transfer member 46 in response to movement of the latching element from the unlatched to the latched position to move the locking member to the unlocked position as the latching element 17 is moved to the latched position. As shown, the latching element 17 is pivotal into latching engagement with the striker 18 against a spring 37 and is retained in engagement with the striker by the pawl 32 which is releasable by means of the member 40 operable by an "outside" push button (not shown). Motion of the member 40 is transmitted to the pawl 32 by the transfer member 46 which is (pivoted on the member and which includes an abutment 49 which is adjacent to an abutment 50 on the pawl, such that when the member 40 is pivoted counterclockwise about the pin 34 the abutment 49 contacts the abutment 50 to turn the pawl 32 out of engagement with the element 17. When the transfer member is pivoted to the position shown in Fig. 1, motion of the member 40 is not transmitted to the pawl since the path of movement of the abutment 49 is then moved away from the abutment 50 and the latch is looked. The transfer member 46 is moved to the looking and unlocking positions by the locking member 51 through an "inside" rod 58 or by an "outside" key cylinder through a shaft 60 and a forked member 61. The cancellation member 65 is arranged so that a flange 69 thereon always abuts an edge 72 of the member 51 when the transfer member 46 is in the "locked" or "unlocked" positions and such that when the locking member 51 is in the locking position an arm 67 of the member 65 lies in the path of an abutment 74 on the element 17 as the latter turns from the unlatched to the latched position as the door is closed and snaps the member 51 to its unlocking position. Keyless locking is achieved by holding the push button depressed as the door is closed, an arm 75 of the transfer member 46 then shifting the cancellation member 65 to a position in which its arm 67 is out of the path of abutment 74.

Abstract: 507,742. Extracting fish liver oils. BROOKES, N. E. (Gorton-Pew Fisheries Co., Ltd.) Dec. 19, 1938, No. 36916. [Class 91] Oil is extracted from fish livers by treating the preferably comminuted livers with an alkaline buffer solution to give a mixture of pH value of 8À5 to 12À5 whereby the tissue is dissolved, whereupon the liberated oil is separated from the aqueous part. Alkaline buffer substances specified are, tri-sodium or potassium phosphate, borax, sodium tetraborate, or ammonium hydroxide. Dilute alkali metal hydroxide solutions and alkali salts which hydrolyse to form insoluble precipitates, such as sodium silicate, are excluded. Free alkali may be present with the alkali salts. Fish livers, fresh or thawed if received frozen, pass to a cutter 2 and are comminuted. The resulting mass is conveyed to a tank 5 to which ammonia solution of 26 to 28‹ BÚ is admitted. The charge is diluted with water and heated by open steam jets or a coil 7, to about 170‹ C. A small amount of salt may be added. The agitated mixture passes to a centrifuge 14, provided with a byepass pipe and relief valve 24. The aqueous liquid is discharged through a pipe 22, and the separated oil through a pipe 16 into a tank 17, where it is washed with water containing a fruit acid such as citric acid to neutralise traces of ammonia. The mixture is again separated in a centrifuge 18, and the wet oil is discharged into a tank 26 where a desiccant, such as anhydrous sodium sulphate, is added. The oil is again separated in a high speed centrifuge 21. Livers from cod, halibut, sword fish, tuna, shark, or whiting may be treated.

Abstract: 1,098,478. Preventing inductive disturbances. KABELWERK DUISBERG. Sept. 2, 1965 [Sept. 3, 1964], No. 37574/65. Heading H4R. To reduce the effect of currents induced in a telecommunication cable by neighbouring electric power lines or a sudden rise in earth potential due to the short-circuit by some electrical equipment, the cable is coiled in one or more turns around magnetic cores spaced along the length of the cable, in order to increase the inductance, and the cable conductors are connected in parallel by connecting both ends of each conductors to earth through impedances, so reducing the cable resistance and draining away to earth any induced currents. The conductor ends may be earthed through over-voltage diverters (Fig. 1, not shown) which only connect to the ends to earth when they respond at a given voltage level, or pairs of conductors forming a two-wire transmission path may be connected to a winding of a repeater coil having an earthed centre-tap (Fig. 2, not shown). The cable may or may not have a metal sheath. For a cable with few conductors the cable resistance may be reduced still further by paralleling an additional conductor, either in the form of a central core or outer strip.
