[Also in Division B5] An external thread is formed on a metal or synthetic resin tube by compressing the tube axially between dies while supported by a mandrel. The thread 98, Fig. 6, can be single- or multi-start and extends from an axial slot 96 previously formed in the tube. The end 97 of the tube is clamped within pivoted half-bushings 78 and 79 (Fig. 3, not shown) operated through levers 71 and 72 from an hydraulic cylinder 67. Between the tube end and bushings and attached to the bushings, are half dies 57 whose end faces 61, Fig. 4, combine to form a helical surface. Coaxial with the tube is an hydraulic ram 20 to which is attached, with the interposition of spacers 30, 32 and 35, and a collar 36, a mandrel 34 with a reduced end 40. Surrounding the mandrel and held within a sleeve 42 is a second die 45 which is of cylindrical form with its left hand end formed with a helical surface (Fig. 5, not shown) corresponding to the faces 61. As the ram 20 is moved to the left the mandrel enters the tube and the wall of the tube is forced into the space between the helical faces of the die ports 57 and 45. A pin 86 which co-operates with the axial slot in the tube for location purposes, is withdrawn from the slot during thread forming by the action of a cam follower 39 attached to the collar 36 pivoting a lever 53 operatively connected to the pin. The outer tube 100 (Fig. 8, not shown) of a scaffolding prop can conveniently be threaded in this manner, an inner tube 103 sliding within the tube 100, and a collar 109 being threaded on its end. Adjustment of the length of the prop is made by choosing an appropriate hole 105 for a pin 106 and finely adjusting the length by rotating the collar 109.

IPC: F16D57/04
Filed: 1957-07-31
Abstract: 892,314. Hydraulic couplings. HEENAN & FROUDE Ltd. July 29, 1958 [July 31, 1957], No. 24321/57. Class 69 (2). [Also in Group XXXIV] An hydro-kinetic apparatus comprises a housing 1 defining a fluid-pressure chamber 2 having inlet and outlet means and containing a rotor 3 secured to a rotatable shaft 9 and a stator 4 freely rotatable relative to rotor 3, valve means 21 for varying the flow of fluid into chamber 2, and means 11, 12 for restraining the stator against rotation when it is desired to exert a braking effort on the rotor, the outlet means including a leakage path 27, 28 for opposing free flow of fluid and having a predetermined pressure flow characteristic. The stator 4 is secured to a sleeve 10 surrounding shaft 9 and terminates in a brake drum 11. A vaned pump 14 driven by shaft 9 delivers fluid via passages 15, 20, valve 21, passages 22, 23, chamber 24 and passage 34 in stator 4 to chamber 2 and the working compartments 26, fluid being expelled via labyrinths 27, annulus 28 and passage 29, a labyrinth 30 prevents excessive flow of fluid back to chamber 24 and vice versa. When the stator 4 is braked by brake shoes 12 engaging drum 11, the apparatus acts as a hydro-kinetic brake, the valve 21 controlling the flow of fluid to compartment 26 and the degree of braking. By releasing or omitting brake 11, 12, stator 4 is able to rotate and the device acts as a clutch, the torque transmitted being varied by varying the setting of valve 21. Dimensions of labyrinth 27 are given in the Specification to produce an outlet flow rate proportional to the square root of the rotor speed whereby the torque transmitted to the stator is proportional to the square of the rotor speed. The valve 21 and brake 11, 12 may be linked to open valve 21 on application of brake 11, 12 and vice versa. An air vent passage is provided in chamber 2. When the apparatus is used in the power transmission of an internal-combustion engine driven vehicle, the operating fluid can be connected to the engine cooling system so that heat generated by the brake may be either dissipated or used to maintain correct engine working temperatures, the generated heat may also be used in other vehicle heating systems. In Fig. 2, not shown, the apparatus normally acts as a clutch between two shafts, the rotor being fixed to the driving shaft and the stator to a driven shaft, the stator may be braked as before to convert the clutch to a brake. Specifications 691,556 and 736,127 are referred to.

Means are provided, when the electric circuit is closed, for locking the switch in its two extreme positions, the valve 8 being simultaneously locked in its open or closed position. As shown, the pyrometer 14 controls the movements of an armature 11 which makes contact at the upper and lower limits of temperature with terminals 12, 13 to close the motor circuit, while the motor drives a wheel 73. Fig. 4, having an eccentric pin 24 to which is connected a rod 23 actuating a sliding bar 21 which directly operates the switch 18. The switch itself comprises a non-conducting strip 44 which is pivoted at 41 in a casing 40, Fig. 3, and is fitted with a terminal 49 and contacts 45, 46, and is connected by blade springs 64 to a pin 63 on the bar 21. The strip 44 also carries a loop 52 having a tongue 53 engaging behind a spring- pressed sliding abutment 54 so as to lock the switch in its extreme positions. When the bar 21 is actuated the corresponding movement of the pin 63 at first causes the spring 64 to be bent without disengaging the tongue 53 from the abutment 54, then the pin 63 engages one of a pair of pivoted cams 59, which bv co-operating with a pin 57 on the abutment 54 forces the latter backwards until the tongue 53 is released and the switch is allowed to snap over to its other extreme position, the motor circuit being thus broken until it is re-closed by movement of the armature 11.

Abstract: 1,007,892. Rectifying. KOKUSAI DENSHIN DENWA KABUSHIKI KAISHA. June 25, 1962 [June 24, 1961], No. 24347/62. Heading H2F. [Also in Division G3] In a controlled rectifying arrangement the point of commutation is the time at which a voltage bearing a particular relationship to the phase to phase voltage of the two phases being commutated passes through a valve equal to a reference direct voltage. This stabilizes the output voltage against source voltage variations. In Fig. 1 the thyratron 2, for example, which has a grid bias applied through resistor 18 from battery 21, is fired when the voltage ez exceeds the reference direct voltage from battery 14. Since the supply is three-phase the voltage e 2  is in quadrature with and proportional to the phase to phase voltage between the phases e 1  and e 3  between which the current commutates when thyratron 2 is fired. In the arrangement of Fig. 4 the voltage e a  is a full wave rectified alternating voltage which is compared with the reference voltage 31 to determine the times of firing of thyratrons 23 and 24. Three such arrangements form a three-phase rectifier.

Abstract: 336,343. Philadelphia Ice Cream Cone Machinery Co., (Assignees of Berzon, L.). June 27, 1929, [Convention date]. Moving-chamber apparatus. - Relates to means for supplying batter to the moulds of a machine for making wafer biscuits &c. As shown, a row of nozzles 32 is associated with a set of measuring plungers 42 carried on the shaft 40, and one row of nozzles is provided for each row of moulds. The bottom of the batter hopper 22 is closed by a casting 24 and a bushing 26 is housed therein for each row of nozzles. A cylinder 28 is reciprocable within the bush 26 and the plungers 42 are reciprocable within the cylinder 28 and work within compartments formed by partitions 36. Plates 50, 54 limit the movement of the cylinder 28. The lever 61 is connected by a link 65 to the bracket 69, and is pivoted to a member 60 which is slidable on a member 58 extending forwardly from the plate 54. The members 58, 60 are temporarily connected by spring-pressed pawls 63, 72 which are disengaged at the appropriate times by cam strips 68, 78; so that the cylinder 28 and plungers 42 either move together bodily, or the cylinder 28 is arrested and the plunger movement continues. Thus, on the movement of the lever 61 to the left, Fig. 2, the plungers 42 and the cylinder 28 move bodily to the right until the ports 30, 44 and 48, 32 are in alignment. The cylinder 28 is then stopped and the plungers 42 still travel to the right, thereby sucking in batter through the ports 30, 44 and expelling air through the ports 48, 32. On moving the lever 61 back towards the right, the plungers 42 and the cylinder 28 move bodily to the left until the port 46 registers with the nozzle port 32 and the air port 48 is positioned to vent through the ports 34. The cylinder is then checked and the plungers 42 continue their travel and eject the batter into the moulds. Adjustment of the quantity delivered is effected by the milled nut 86 which adjusts the stop 80 on the slide 60 which contacts earlier or later with the face 82 of the cam 78 and thus adjusts the plunger stroke. The device is mounted pivotally on an arm carrying a positioning stop, so that it can be swung into and out of the charging position.
