The engagement is effected by a screw 7 and an adjustable screwed stop 11 ensures the correct meshing. When the screw 7 is retracted, gravity effects the disengagement. The machine may then he worked by hand, a handle being provided on the shaft 2.
Patent GB-1556546-A (GB)
Title: Wave soldering device
IPC: H05K3/34
Filed: 1977-02-17
Abstract: It has a tub (1) which is filled with liquid solder (2) during operation. Two apertures (3) and (4) as well as a circulation pump (6) are provided at the tub bottom (5). A nozzle (7) adjoins the aperture (4). A solder stream (8) flows out of the nozzle (7). A printed board assembly is moved in the direction of the wave (8) for soldering. Located above the liquid solder (2) of the tub (1) is an oil-protection layer (9) which prevents oxidation of the liquid solder (2). So that the solder does not oxidise in the interior of the nozzle, the wall of the nozzle (7) has one or more openings (10) which lead entirely into the oil-protection layer (9). A support with an adjoining baffle plate (12) is to be arranged on the nozzle (7). The free end of the baffle plate (12) leads into a collecting vessel (13). The latter serves to receive the solder stream (8) falling back. The baffle plate (12) prevents spraying of the plunging solder stream to a very large degree. An overflow channel (14) at the collecting vessel (13) provides for a smooth discharge of the liquid solder from the collecting vessel (13) back into the solder sump of the tub (1). Impurities (15) collect in the collecting vessel (13). <IMAGE>

Title: Improvements in or relating to portable electric inspection lamps
IPC: F21L14/02
Filed: 1931-03-04
Abstract: 374,116. Electric hand lamps. GENERAL ELECTRIC CO., Ltd., CORNECK, A. W., and STEGGLES, H. T., Magnet House, Kingsway, London. March 4, 1931, No. 6740. [Classes 39 (ii), 75 (iii), and 75 (iv).] In an electric hand lamp provided with a detachable guard cage, means are provided for positioning the two contacts of the bayonet cap of the bulb relatively to the two spring contacts of the socket and the guard cage carries a member which engages the bulb and presses the contacts of the cap into engagement with the spring contacts.

Patent GB-1096469-A (GB)
Title: Control mechanism for engine combined with infinitely variable gear
IPC: B60W30/18
Filed: 1965-02-17
Abstract: 1,096,469. Controlling vehicles. W. REIMERS. Feb. 17, 1965 [Feb. 25, 1964], No. 6781/65. Heading B7H. [Also in Division F2] The ratio of a steplessly variable gear 4 driven by an engine 8 in a motor vehicle is varied in response to an engine driven spring-loaded centrifugal governor 3, an accelerator pedal 1 being linked to an engine throttle valve 7 and to the governor spring in such manner that for drive, the throttle opening and gear ratio are jointly controlled by the accelerator, while with the throttle closed the gear ratio may be varied by the accelerator to control the degree of engine braking. In Fig. 1, depression of the accelerator 1 from a position O-O opens the throttle 7 and increases compression of the governor spring causing an increase in the numerical gear ratio, while raising the accelerator above the position O-O similarly causes progressive increase of the gear ratio, the throttle remaining closed due to a one-way coupling 6 in the throttle linkage which transmits only thrust. The governor spring is loaded through a bell crank 2 and a lever 10 so that accelerator deflection in either direction from the position O-O increases the loading. The governor may act on the ratio shift control through electrical or hydraulic means. The control is such that the engine always operates at minimum specific fuel consumption. When a diesel engine is used, the throttle linkage controls fuel injection. In Figs. 3 and 4 (not shown) the bell crank 2 is replaced by a cam plate (9). Retaining means (11) may be provided to hold the accelerator in any selected position when the foot is removed therefrom. In Fig. 7 (not shown) the accelerator is movable only in one direction from a rest position, the connection to the throttle being through a lever (12) having a movable fulcrum (36) on a lever (18). Depression of the accelerator jointly increases throttle opening and governor spring loading. Initial depression of a service brake pedal (21) acts through a one-way coupling (20) on the lever (18) to move the fulcrum (36), progressively closing the throttle, until, with the fulcrum (36) in line with the throttle rod (22), the throttle is closed and independent of accelerator movement, which latter then affects only the gear ratio. Further depression of the pedal (21) applies a service wheel or exhaust brake. In Figs. 5 and 6 (not shown) a lever (12) in the throttle linkage is fulcrumed at (13) on one end of a lever (14) which is prevented from pivoting by a member (15). Depression of a brake pedal acts through a one-way coupling to move the member (15), allowing the levers (14, 12) to float, so that the throttle is closed by a spring (23) and remains independent of the accelerator while the brake is depressed.

Patent GB-443056-A (GB)
Title: Improvements relating to the manufacture of esters from alcohols
IPC: C07C67/08
Filed: 1935-03-04
Abstract: The aliphatic acid produced from the corresponding alcohol as described in the parent Specification is directly esterified instead of being extracted with a solvent.  The reaction mixture containing the acid is led to a column containing alcohol and esterification is effected by known methods such as those of Specifications 130,968 and 195,117, [both in Class 2 (iii)].  The solution of chromium salts remaining is electrolytically reoxidized as in the parent Specification.  In an example, the acid reaction mixture is introduced at the top of the column and alcohol vapour at a point a few plates above the bottom.  Vapours of ethyl acetate, alcohol and water issuing from the top of the column may be led to a concentration column which produces a ternary azeotropic mixture from which the alcohol vapour may be removed by washing with water (Specification 234,458, [Class 2 (iii)]); or the mixture may be treated by distillation and rectification as described in Specification 130,968; or it may be brought into contact with a body of water so as to produce two layers, the layer containing the higher proportion of ester being rectified, as described in Specification 195,117.  The liquid issuing from the base of the esterification column may be concentrated to remove the water produced in the esterification by withdrawing steam from the base of the column, and the concentrated liquor is then reoxidized by electrolysis.

Filed: 1967-02-13
Abstract: 1,162,859. Rolling. DEMAG A.G. 13 Feb., 1967 [29 April, 1966], No. 6850/67. Heading B3M. A rolling mill plant for the production of wire includes a loop former 3 positioned between the last stand 2 of a finishing train and cooling sections 5-9, the loop former and pairs of drive rollers 4 and 10 controlling the tension in the wire so that it is constant during winding. In operation, the leading end of the wire operates a photo-electric cell positioned immediately after the rollers 4 to speed up the stand and to form a loop at 3. Further cells, located between the sections 5-9 and in front of a horizontal winding drum 14, serve to successively switch on water supplies to the sections, and to control winding of the wire. After the wire is initially wound on the drum from the loop, the drive rollers are disengaged and the rollers 4, 10 act as a brake to regulate the wire tension. The loop former 3 may be used to control the rolling speed and/or the rollers 4 and 10, according to the size of the loop. To wind the wire on the drum either a reciprocating guide tube 24 is used or a drum which is slid axially on a carriage 21.

Abstract: 855,606. Push-button switches. OAK MFG CO. Feb. 27, 1959 [Feb. 27, 1958], No. 6899/59. Class 38 (5). [Also in Group XXV] A push-button mechanism is disclosed with a latch retaining it in the "in" position but releasable on further depressing the button. The mechanism is shown in the " in " position preparatory to locking. Latch 33 is moved towards the right by the spring 42, pin 31 sliding in the slot a to allow the part 36 to engage the surface 39 and pivot the detent head 46 over a latching bar 47. A further (unlocking) depression of the button allows the latch to move further to the right so that pin 31 is to the extreme left of slot a and the part 36 is engaged by the surface 39 to tilt the latch anticlockwise, thus lifting the detent head 46 clear of the latching-bar 47. The mechanism can now move to the fully open position. Finally the cam surface 38a engages 36 to move the latch so that pin 31 can assume its original position. The latch bar can be moved sideways to allow the detent head to enter a slot in the bar and thus unlock the mechanism. A modified construction is disclosed in which the unlatching is obtained by a cam surface on the end of the detent head 46 engaging a similar surface on the frame.
