Title: Automatic transmission controls
IPC: F16H61/06
Filed: 1977-04-12
Abstract: 1518614 Change speed gear control AUTOMOTIVE PRODUCTS Ltd 12 April 1977 [20 April 1976] 15891/76 Heading F2D  An automatic transmission has four forward speeds and reverse, there being a forward clutch 11, a second gear brake band 13, a third gear brake band 14, a top and revearse gear clutch 12 and a reverse gear brake band 15. Manual selection of the lower three gears, reverse, neutral and a park lock is by a selection valve 19. In position D of valve 19 the forward gears are controlled by a valve 42 whose position is responsive to output speed, through linkwork from a speed responsive device 57, and to throttle pedal position acting on a spring- loaded abutment 58 on a rod 54 in the linkwork. To prevent partial movement of valve 42 to a new ratio position causing clutch or brake slippage snap-action valves 39, 41, 84 associated with second, third and fourth gears only open when there is sufficient pressure generated upstream of a restricted flow to drain. When the third and fourth gear valves 41, 84 snap open on upshift they cause the second and third valves 39, 41 respectively to close. Accumulators 38, 90 smooth the engagement of clutches 11, 12 respectively. An accumulator 98 smooths the engagement of third gear from fourth at small throttle openings, the accelerator controlling a valve 97. Kickdown is provided by an actuator 108 acting on rod 54 of the control linkwork when valve 97 is moved sufficiently. Valve 97 also controls a pressure modulator 17 to increase pressure as the throttle is depressed. The emptying and filling of the actuators 131, 141, for brakes 13, 14 happens at substantially the same rate to provide smooth shifts. The pressure from modulator 17 is also increased in reverse.

Title: Improvements in or relating to circuit-arrangements adapted for the supply of electric oscillations to a load
IPC: H04J1/06
Filed: 1946-05-28
Abstract: 637,507. Thermionic valve circuits. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. May 28, 1946, No. 16227. Convention date, Sept. 14, 1939. [Class 40 (vi)] An oscillator or amplifier comprising two valve circuits arranged in parallel to serve as alternatives in the event of failure of one, are so arranged that part of the alternating voltage in one circuit is rectified and used to block the other. In Fig. 3 the alternative amplifier valves 25 and 30 have the input applied through a common transformer 23 and feed a common output transformer 24. Part of the output from the normally operative valve 25 is rectified in circuit 27, 28, 29 to provide a blocking bias for valve 30. When. a varying signal such as speech is being amplified a pilot super-audio frequency is fed into transformer 33 and the rectifier circuit is tuned to this frequency by condenser 34. Switches 31, 32 are provided to enable the suppressing bias to be temporarily short-circuited and thus permit selection of the equipment for normal operation. To avoid the failure of one valve disturbing the alternative circuit, the two circuits may be connected to the load through a hybrid transformer (Fig. 4, not shown), or through the contacts of a relay connected in the.anode circuit of one valve and which changes over when the anode current of that valve fails (Fig. 5, not shown). Specification 507,271 is referred to.
Patent GB-334186-A (GB)
Title: Improvements in and connected with the manufacture of glass containers
Filed: 1929-05-27
Abstract: 334,186. Forster, A. C. May 27, 1929. Blowing hollow-ware. - Relates to the manufacture of glass bottles or jars of the kind in which a ledge is formed around the inside of the mouth to form a seating for a closing device, such as bottles for holding foodstuffs or milk. According to the invention, a ring mould used in a machine for making this ware is so formed that the, glass which constitutes the seating is prevented from being deformed by the action of the air when a parison is blown to a finished bottle. The ring mould comprises an outer portion 2 made, as usual, in hinged sections, and an inner sleeve 3 by which the seating at the mouth of the bottle is formed. The sleeve 3 has a cylindrical extension 3<x> which lies within the cylindrical casing 4 of the mould mount. A mouth-forming plug 5 slides in a cylindrical cavity in the sleeve 3, and its base normally rests on a flange 6 on the sleeve and is kept in place by springs 11, 12. A tubular spindle 7, screwed into the plug, allows air to be blown into the mould through passages 16 in the plug. The sleeve 3 is formed with a cylindrical top portion 15 and a ledge 14 which forms the seating at the mouth of the bottle. In use, molten glass is fed into the parison mould 1 in the usual way and is forced by compressed air or suction down into the space surrounding the sleeve 3, the plug 5 being raised to the position shown in dotted lines. The plug is then lowered, and air is blown into the space thus formed to expand the glass. During this operation, the glass is drawn away from the top of the part 15 of the sleeve 3 by the stream of air passing up around the plug, but the glass on the ledge 14 is protected by the part 15 and is not deformed. The seating thus formed in the mouth of the bottle remains flat, and an airtight joint can be formed with a closure device.

Filed: 1938-05-31
Abstract: 515,524. Drilling paper sheets &c. GRIFFITH, M. J. May 31, 1938, No. 16229. [Class 83 (iii)] [Also in Group VIII] A machine for performing drilling and like operations on flat material at predetermined distances apart, such as a paper drilling machine, comprises a fixed table c and a vertieally movable drilling head A carrying a single rotating hollow drill B. A base 1 with scale markings 29 is secured to the table C by clamps 2 and is formed with a bearing strip 3 on which is mounted a gauge slide 4 connected by a cord 5 to a weight 5a. A lay stop 6 having an L- shaped projection 6b and a spring pawl 8 is adjustably mounted on a screw 7 carried by the gauge 4. A rod 11 is rotatably mounted between brackets 10, 10a at the ends of the base 1 and carries links 12, 12a between which is mounted a second rod 13, the two rods 11, 13 forming guides for adjustable stops 18. The link 12 carries a post 14 connected by a spiral spring 15 with an extension 16 of the bracket 10 so that the links are normally held in an upright position against a stop 17. On the bracket 10 is a sliding member 21 having a lateral projection 21a for engaging the post 14 and connected by a spiral spring 22 to an extension 23 of the bracket 10 and by a Bowden cable 24 to an actuating lever 25. In operation the work F is placed on the table C and bearing against a gauge plate 4a carried by the gauge slide 4 which has been manually adjusted so that the pawl 8 engages the first stop member 18. As the drill head nears the end of its downward stroke a projecting arm 28 engages the lever 25 to move the slide 21. This rocks the links 12 and stops 18 so that a tooth 20 on the first stop member moves away from the pawl 8 and under the action of the weight 5a the slide 4 tends to move away from the drill but is prevented by the engagement of the. tooth 20 with the L-shaped projection 6b. After the hole is drilled and the head A rises, the lever 25 is released, the first stop member 18 rocked away from the projection 6b and the weight moves the slide until the second stop 18 engages the pawl 8. The work is then in the position for the drilling of the second hole.

Title: Dual controller for dental drills
IPC: A61C1/00
Filed: 1961-05-04
Abstract: 916,060. Dental drills. RITTER CO. Inc. May 4, 1961 [May 23, 1960], No. 16241/61. Class 81 (2). In dental drilling equipment both the motordriven drill and the turbine drill are controlled by the same foot switch. The controller itself comprises a casing having a foot lever which is moved sideways from a central position to determine the speed and direction of the motordriven drill. Movement of the lever also displaces a slide which actuates the control plunger of an air pressure regulator, which feeds air to the turbine drill. The power supply which becomes operative is determined by a changeover switch which is moved by the withdrawal or replacement of the turbine drill. As shown diagrammatically, the latter switch has three blades 94, 95, 96 which are in their lower position when the counterweight 92 of the turbine drill 17 is in its lowest position. Pulling the drill out to position 17A allows the arm 93 to rise and the contacts to change to their upper position. With the switch contacts in their lower position the wiper arm 28 of the controller 19 may be moved in either direction from its neutral position 22, to engage resistances 26, 27 and thereby complete circuits, determining the running direction, from mains lead 104 through the motor field winding 108 and armature 114 to the second mains lead 117. At the same time, circuits may be completed through switches 99, 100 to solenoids 97, 98 to control the supply of water and air respectively to the handpiece. When the turbine drill 17 is withdrawn for use and the contacts 94, 95, 96 change over, the supply to the field winding 108 is interrupted, but current is supplied to a solenoid 144 which causes air to be fed to the pressure regulator. At the same time the switch 99 may be used to control energization of a solenoid 142 which, in turn, controls a supply of water to the drill 17.
