Filed: 1933-11-01
Abstract: 412,140. Switching-systems for consuming devices. PRESSED STEEL CO. OF GREAT BRITAIN, Ltd., Cowley, and SIMMIE, W. S., 3, Stanley Road, both in Oxford. Nov. 1, 1933, No. 2925/34. Divided application. [Class 38 (iv).] In spot seam resistance-welding apparatus the periods of passage and interruption of welding current are determined by a high speed commutator or timing switch 22, one or more segments 74 of which may be connected in a control circuit by the insertion of plugs in the static contact-making arrangement A, B, the passage of welding current only occurring when these segments are contacted by the rotating brush 26. If plugs are inserted to connect contacts 1 and 2 to bus-bars 64, 63 respectively and switch 71 is closed, the bush arm 26, which is rotated by a synchronous motor and contacts each segment for one half cycle of the supply, contacts the segment 74 once per revolution and permits current to flow through contact 1, inserted plug, bus-bar 64, any adjustable part of the resistance 81 and the primary 15 of the welding transformer 14 thus producing welding. On leaving the segment 74 the arm 26 contacts the adjacent segment, which is connected through contact 2 to the bus-bar 63, thereby permitting a reduced current to flow through an adjustable part of the resistance 80, the resistance 81 and the primary 15 of the welding transformer. This reduced current is insufficient to produce welding, but assists in preventing sparking in the apparatus. In a modification (Fig. 2, not shown), a similar control arrangement operates a contactor switch in the primary circuit of the welding transformer and as it does not provide for the passage of a reduced current subsequent to the passage of the welding current, no resistances are employed therein and only one bus-bar is used in the static contact making device which may comprise a switch box with spring contact fingers. In the above described apparatus, various welding and cooling time periods may be produced by altering the arrangements of the inserted plugs or the speed of the brush arm 26 while different segmental rings may be employed for different kinds of work. Specification 389,460 is referred to.

Title: Regulating system for batteries
IPC: H02J7/14
Filed: 1958-01-30
Abstract: 860,500. Systems for charging and discharging batteries. SOC. DE L'ACCUMULATEUR FULMER. Jan. 30, 1958 [Feb. 2, 1957; Jan. 9, 1958], No. 5134/58. Class 38 (4). Relates to a system in which a battery 2 has a resistor 9 in its charging circuit and a resistor 11 in its discharge circuit, these resistors being controlled by means of a switch-contact 3 which is responsive to the gaseous discharge from the battery. As long as the gas-pressure is below a predetermined value, contact 3 engages terminal 7 to short-circuit the charge resistor. When the pressure becomes excessive, however, contact 3 is made to engage terminal 8 whereby the resistor 9 is included in the charging circuit, and the resistor 11 is short-circuited. In another arrangement, the system includes a relay, and two load circuits connected with the headlights and other lights of a vehicle, for example. When the pressure-responsive switch is closed, the relay is energized to short-circuit the charge resistor, but, when the pressureresponsive switch opens, the relay is deenergized to short-circuit discharge resistors in the two load circuits, Fig. 3 (not shown). This arrangement comprises a pilot lamp to indicate the state of operation of the relay, the circuit of which also includes a manual switch. The charge resistor may be replaced by the coil of a relay in parallel with that of the first relay. This second relay controls the number of effective coils of the alternator connected to the battery, Fig. 6 (not shown). Two resistors may be connected in series between the current source and the battery, one of these resistors being shortcircuited when the pressure-responsive switch is in the position corresponding to low gas pressure. When the pressure becomes excessive, however, both resistors are put under the control of a relay responsive to the discharge current, so that the resistors are short-circuited if the discharge current is sufficient to energize the relay, Fig. 4 (not shown). A further relay may be added, having a coil controlled by the pressure-responsive switch and a contact for alternately controlling resistors in the charging circuit and in an additional load circuit, Fig. 5 (not shown). In another modification, the alternator connected to the battery has four windings, and, when the pressure-responsive switch is opened, and the load is disconnected, only one winding is included in circuit for minimum output. When the load is switched on, the pressure-responsive switch being still open, the alternator provides an output of intermediate value. Maximum output is afforded when both the pressure-responsive switch is closed, and the load is switched on, Fig. 7 (not shown).

Title: Improvements in or relating to methods of and apparatus for forming a paper or like bag
IPC: B31B29/00
Filed: 1951-02-09
Abstract: 684,890. Making paper and like bags. ROBINSON (CANADA) Ltd., E. S. & A. Feb. 9, 1951 [Feb. 9, 1950], No. 3216/51. Class 94(ii) Relates to a method of forming a self-opening satchel bottom bag from a tube with side bellows folds, or of converting an already formed plain square bottom bag to a self-opening satchel bottom bag. As shown in Fig. 1 a plain square bottom type bag 10 comprises a length of flattened tubular material having opposed bellows folds 11, the end 12 at the bottom forming portion being sealed and folded back about a fold line 14 and secured to the adjacent side wall by an adhesive. Spaced parallel crease lines 15 and 16 are also provided. A forming anvil 18 is movable toward the bottom edge 14 of the bag, and two opening blade mechanisms 21 are arranged on opposite sides of the bag. The mechanisms 21, Fig. 16, comprise blade-like members 23, 24 mounted for coaxial contrarotating movement on a sleeve 26, and a shaft 25 respectively, means being provided to rotate the sleeve 26 and shaft 25 relative to each other in the desired manner. When the blade mechanisms 21 are moved to their innermost position, adjacent the inner limits of the bellows folds 11, the anvil member 18 is moved toward the bottom fold 14 to grip the bottom folded portions of the bag between the edge of the anvil and the edges of the folding blades 23, 24, Fig. 5. The blades 23, 24, are then opened, Fig. 7 and 8, to produce a square flat bottom in the bag 10, Fig. 13 and 14, comprising rectangular areas 33, 34, extending between the initial fold line 14 and the transverse crease lines 15, the bottom ends of the bellows folds being formed into connected pairs of triangular shaped fold portions 35, 36. The blades 23, 24, are moved to the position shown in Fig. 9 and force the bottom forming portions 33, 34 against the surfaces 19, 20, of the anvil member 18, causing the side walls of the bag to collapse inwardly, and a pair of opposed creaser members 41, 42, are moved into pressing engagement with the bottom of the bag. This produces the triangular fold portions 39, 40, and 47, 48, in the bag. After the members 41, 42 are withdrawn the blade 23 is moved .clockwise, Fig. 11, to position the folded bottom portion at an angle to the plane of the collapsed body portion, and the blade mechanisms 21 are then withdrawn and the anvil member 18 retracted. The 'bag is then passed between a pair of endless belts, Fig. 12 (not shown) to flatten the bottom of the bag against the body. An alternative method of producing a bag having the same bottom formation is described, Fig. 17 to 30 (not shown). The portion 12 is not initially bent over and secured to the side wall as in Fig. 1, but the anvil member comprises two jaws which grip the portion 12 during the folding operations, after which this protruding portion is attached to the bottom forming portion of the bag.
