Abstract: 390,638. Change-speed clutches. DAIMLER-BENZ AKT.-GES., Untert³rkheim, Stuttgart, Germany. April 4, 1932, No. 9590. Convention date, April 4, 1931. [Class 80 (ii).] In gear-control mechanism for power driven vehicles having an alternate clutch arrangement 14, 15, actuated by a lever 16 which is in turn displaced by a second lever 24 actuated by the driver, the lever 16 has a cam track 28 on which a roller 27 on the lever 24 travels, either the cam track or the roller being yieldingly mounted on its lever so that the levers are mutally urged to their end positions. The clutches 14, 15 have bevelled teeth so that they engage noiselessly when their peripheral velocities become equal. In the form shown in Fig. 2, the roller 27 is connected to a piston 25 which slides in the hollow lever member 24 under the influence of a spring 26, and the cam track 28 is integrally formed on the lever 16, which has adjustable stops 31. The clutch 14 connects a shaft 10 journaled in the driving shaft 1 and having fixed to it a toothed wheel 9, with a hollow shaft 11 on which are slidably keyed gears 12, 13. The clutch 15 connects a shaft 5 having a wheel 8 permanently meshing with the wheel 9, with a hollow shaft 4 to which are fixed gears 3, 6, 7, the gear 3 permanently meshing with a gear 2 on the driving shaft. The gears 12, 13 are operated by strikers connected to two sleeves 19, axially slidable by means of the driver's lever 17. A third sleeve 21 has a projection engaging a fork on the lever 24. The direct drive is obtained by the engagement of a clutch connecting gears 2, 12. The sleeves are so arranged that it is impossible to operate the over-drive through gears 2, 3, 8, 9 until the direct drive has been put in. The lever 24 may be actuated by a separate control lever which operates the sleeve 21 only or which is directly connected to the lever 24, or the lever 24 itself may be used as the control lever.

Title: Control system for electric stud welding apparatus
IPC: B23K9/20
Filed: 1963-03-13
Abstract: 1,029,403. Welding by pressure. K.S.M. PRODUCTS Inc. March 13, 1963 [June 8, 1962], No. 9935/63. Heading B3R. [Also in Divisions H1, H2, and H3] In stud welding apparatus in which the stud is lifted and an arc is struck for a duration controlled by a timer, the timer includes a unijunction transistor which controls a switch to disconnect the welding current and thrust the stud against the work. After the welding gun 20 and the stud 26 have been pressed against the work 28, operation of a trigger switch 38 connects a D.C. supply 40 through a rectifier 58 to the timer 24 and energizes relays 42, 36 in turn to strike a pilot arc via a resistance 52, operates a solenoid 32 to lift the stud 26 and shunts the trigger switch 38. After a slight delay relay 54 applies the full welding current. The output of the rectifier 58 voltage regulated by a diode 60 is fed in parallel to a uni-junction transistor 68 in a voltage divider 76, 77 and to a network of resistors 62, 64 and a condenser 66. After a time, partly dependent on ambient temperature since the relative currents in the transistor 68 vary with temperature, the voltage across condenser 66 reaches a value such that a sudden increased current flows through the transistor 68 from the emitter 74 to base terminal 70. The resulting pulse from resistor 76 fires a silicon-controlled rectifier 78 to actuate relay 80. The welding current is disconnected and the stud 26 is forced by a spring 34 into welding engagement with the work 28. The rectifier 78 continues to conduct until the timer is disconnected to prevent re-cycling.

Abstract: PCT No. PCT/GB90/01985 Sec. 371 Date Jul. 13, 1992 Sec. 102(e) Date Jul. 13, 1992 PCT Filed Dec. 20, 1990 PCT Pub. No. WO91/09781 PCT Pub. Date Jul. 11, 1991.When dispensing carbonated beverages, particularly beer and draught stout, it is desirable to obtain a close-knit creamy head. This contributes to a creamy taste and adds considerably to the customer appeal. To obtain this effect when dispensing from a can (1) it includes a lid (2) having a secondary compartment (4) formed on it and a non-resealable closure (3) in communication with the secondary compartment. At least one orifice (5) extends between the secondary compartment (4) and the inside of the container (1), and a liquid (8) is held in the secondary compartment. The container is arranged so that on opening of the closure (3) the pressure in the secondary compartment (4) is reduced to atmospheric with the result that gas or liquid from the main body of the container (1) is jetted through the at least one orifice (5) into the liquid (8) in the secondary compartment (4) to generate a foam in the secondary compartment. Complete opening or removal of the closure (3) enables the contents of both the secondary compartment (4) and the remainder of the can (1) to be mixed and dispensed together so that the foam produced in the secondary compartment acts to seed the generation of small bubbles throughout the beverage (8) in the can (1).

Filed: 1999-01-06
Abstract: PROBLEM TO BE SOLVED: To provide a cylindrical body which is highly pliable and is hardly deformable at a high temperature by forming the cylindrical body consisting of a 4-methyl-1-pentene polymer with a specific thickness on the outer surface of a hollow cylindrical mandrel. SOLUTION: A 4-methyl-1-pentene polymer is a monopolymer of 4-methyl-1- pentene or a copolymer of 4-methyl-1-pentene and 2-20C α-olefin such as other ethylene or propylene, and is a polymer composed mainly of 4-methyl-1-pentene containing at least 80 wt.% 4-methyl-1-pentene structural unit. A cylindrical body comprising a 4-methyl-1-pentene polymer with at least 1 mm thickness is formed on the outer surface of a hollow cylindrical mandrel. It is possible to lower the bending modulus of elasticity by making the cylindrical body hollow and consequently make its winding around a drum easy during vulcanizing. Thus the cylindrical body of the described polymer shows high pliability, heat resistance and reliable mold release characteristics, and besides, is hardly deformable even at a high temperature.

Abstract: PURPOSE:To attain a switching circuit having a large dynamic range with a simple circuit constitution by inserting the 1st and 2nd transistors (TR) having polarities opposite to each other to a signal system and intermitting the signal system with the bias intermittence of said transistors. CONSTITUTION:When a switch S3 is changed to the side (a), the power supply +Vcc is applied to the anodes of diodes D1 and D2. Thus these diodes are biased forward and turned on. Therefore the output of a low frequency circuit 4 is amplified by a low frequency amplifier 5 and supplied to a low frequency amplifier 6 after undergoing the limitation of amplitude through diodes D1 and D2. In this case, a signal system 8 is cut off since the 1st and 2nd TRs Q3 and Q4 are kept off. Thus only the signal that is transmitted via a signal system 7 with the suppressed level. When the switch S3 is changed to the side (b), the TRs Q3 and Q4 are turned on. Then the output signal of the circuit 4 is transmitted to the amplifier 6 via the system 8.
