Title: Improvements in welding apparatus
IPC: B23K11/11
Filed: 1940-04-02
Abstract: 540,107. Welding. VAUXHALL MOTORS, Ltd., and DAVIDSON, C. F. April 2, 1940, No. 5895. [Class 83 (iv)] A welding apparatus having a fluid operated electrode, a reverse valve and trigger for controlling the admission of fluid pressure to the operating cylinder of a pressure switch for closing the welding circuit at a predetermined pressure has a timer which on conclusion of the weld time operates an electric valve so that fluid pressure is supplied to the reverse valve in order to position it for release of fluid pressure from the work. Compressed air passes from main pipe 1, Fig. 1, through reverse valve 2 and pipe 36 to close the trigger valve in the handle 4 of the welding gun. When the trigger 6 is pulled to open the trigger valve air pressure raises the trigger keeper 7, also passes into the cylinder 8 to effect the outward stroke of the electrode 11 and is admitted also to the pressure switch 9. When the correct welding pressure is established the switch 9 is closed so as to cause the welding contactor 14 to close and supply current to the welding transformer 16. A current condenser discharge timer 18 of the kind described in Specification 431,518, provided with variable rheostat 20 and coupled in series with the primary 19 of the transformer is also put into action to set the welding time, after which the timer through an auxiliary circuit 21 momentarily initiates operation of an electro valve 22, which is self maintained by a parallel circuit 23. The valve 22 which is connected to the main supply pipe 1 is thus opened to connect the pipe 1 and pipes 24, 25 to the cylinder 26 through an adjustable screw 27 so as to reverse the valve 2 during which interval the weld solidifies under pressure. When the valve is reversed the forward end of the cylinder 8 is connected with the supply to return the electrode 11 and at the same time to disengage the trigger keeper 7 and also the switch 29 in the circuit 23 so as to de-energize the electro valve 22 which thus returns to closed position. The time of operation of the switch 29 is determined by an adjusting screw in the pipe line to the switch. The valve 22 and thus the valve 2 are consequently returned to initial position to complete the cycle, which is repeated by maintaining pressure on the trigger. In Fig. 2 hydropneumatic contact is used. The reversing valve 2 is connected to the trigger valve through a reducing valve 30 in the pipe line 3. When the trigger is pulled compressed-air operates the keeper 7 and also passes through pipe 32 to a cylinder to lower the piston 27 and so through hydraulic pressure in cylinder 31 and in cylinder 34 operates the electrode piston which is pivoted to the lever 35 carrying the electrode 11. When the electro valve 22 is opened so as to allow reversal of the valve 2 live air in the line 28 passes via line 36 to the bottom of the hydro-pneumatic relay 31 to push up the piston 37 so as to release the work. At the same time the keeper 7 is released and the switch 29 opened to return the valves 22 and 2 to normal position.

IPC: B65G67/00
Filed: 1927-03-03
Abstract: 275,114. Norton, B. March 3, 1927. Rotary tipplers.-Wagons a, b, running down an incline to a tippler 11 are checked by a spring, cataract or other separate retarding device 1, 2, so that the front wagon engages gently with a trip lever 6 and passes into the tippler. The movement of the lever 6 to the position shown in broken lines actuates a toggle, cam or equivalent device 4 to raise a stop lever 3 and hold back the second wagon b. When the tippler has made its revolution the wagon a is released and runs cut and the stop lever 12 in the tippler is reset. Towards the end of the revolution, a projection 10 on the tippler actuates a bell-crank lever 9 turning on a vertical axis, so as to re-set the trip lever 6 and release the stop lever 3.

Filed: 1955-03-01
Abstract: 774,324. Hinges. MIDDELBOE, S. March 1, 1955 [June 26, 1954], No. 5970/55. Class 65(2). A joint, for example, for a lamp bracket, comprises a pair of complementary partspherical members 14, 16 relatively rotatable about an axis, one member 16 having a slightly larger diameter than the other and locking means connected with the latter being engageable with part of the surface of the former in any relative position of the members. In the form shown the joint members are formed with necks 46, 64 and the axis of relative movement of the members is at an angle to this axis, perpendicular to a plane on which the two members meet. The locking means is constituted by a sleeve 36 screw-threaded on a fixing member 18 in which the neck of the joint member 14 is rotatable; this rotation is limited by a lug 50 on the neck 46 engaging a stop-pin 30 in the member 18, which is internally screwthreaded to receive a tubular bracket member. The neck of the joint member 16 has an external screw-thread and an abutment collar. The two joint members 14, 16 are held together rotatably by a resilient ring 82 in complementary annular recesses in interfitting parts of the members; the member 18 is similarly held on the neck of the member 14. The member 36 may be carried directly on the neck of the member 14, or it may be carried by the member 16 to engage the surface of the member 14; it may be slidable or otherwise movable into frictional engagement with the spherical surface. The members are bored for the passage of an electric cable through the joint.

Title: Improvements in or relating to labelling machines
Inventor: FAIREST MORGAN
IPC: B65C9/36
Filed: 1956-02-27
Abstract: 809,463. Labelling machines. FAIREST Ltd., M. Feb. 22, 1957 [Feb. 27, 1956], No. 5976/56. Class 73 [Also in Group XVI] Relates to machines for applying labels which carry an identification marking, such as a date stamp. The invention comprises a drum 2 which delivers labels 7 to a labelling station and a marking cylinder 15 which rotates eccentrically about an axis 16 parallel to that of the drum and at the same peripheral speed to contact the label 7 and an inking pad 35 once on each of its revolutions. Labels 7 from reciprocating stacks 8 are picked up by an intermittently rotatable box 10 and gummed along their edges. They are transferred by a member 13 to the drum 2 where they are held gummed face outwards by two suction holes 14. Bottles 3 on a conveyer 1 are spaced by a worm 4 to receive labels as they pass a presser pad 6 at the labelling station. Before reaching the labelling station each label encounters the marking cylinder 15 carried eccentrically on a disc 17 geared (Fig. 2, not shown) to rotate synchronously with the drum 2. A stem 18 carries a bank of marking discs 20 which are interpositioned laterally by studs fitting into holes in their sides and can be turned for typesetting by separating them against the force a spring 22 held with them between collars 19 and 23. The collars 19 and 23 are attached to pillar 18 by set screws 50, thus enabling the height of the marking discs 20 to be adjusted and a fine adjustment for lateral position is provided in the gear train by means of a stud and arcuate slot (Fig. 2, not shown). The ink-transfer roller 35, led from a reservoir 32 through a wiper 34 inks type 21 on the rings 20, by rotating on an axis 36 to contact, the cylinder 15 once per revolution of the disc 17. A bracket 41 carrying the disc 17 and ink roller 35 can swing on a pivot 28 (Fig. 3, not shown) against the pull of a spring 45. Detectors 44 and 46 on the conveyer react to the absence of a bottle in the regular spacing to prevent in anticipation, the corresponding label from being picked up from the stacks 8 and cause a solenoid 42 (Fig. 2, not shown) to swing the bracket 41 away from the drum 2 at the appropriate time to prevent printing action.

Title: Improvements in or relating to slides for microscopes and other image creating optical devices
IPC: A61B5/145
Filed: 1935-03-02
Abstract: A slide for a haemocytometer, microscope, or other image forming optical system comprises a transparent body one face of which has a semi-transparent coating subdivided into zones by lines of a different degree of transparency.  The semi-transparent coating may be applied by forming a coating of a substance such as chromium on a tungsten wire, the latter being supported near the glass plate in a partial vacuum and heated by an electric current, whereupon the substance distils and is deposited on the plate. The coating may be deposited from a colloidal solution.  For example a colloidal solution of neutral platinic chloride in lavender oil may be applied as a thin film to the glass plate and the latter first heated to drive off the volatile matter and then to burn the carbonaceous matter and fuse the platinum on to the glass.  The coating may be fixed by a subsequent heat treatment.
