Title: Improvements in tennis rackets and the like
IPC: A63B51/12
Filed: 1924-06-05
Abstract: 233,544. Wright, A. A., Howlett, W., and Lynch, E. C. June 5, 1921. Rackets.-In a metal tennis racket or the like of the kind wherein the stringing is tightened by means of a nut which operates a tube and wedge. such as the racket described in Specification 224,724, the wedge and frame, after adjustment to obtain the required tension of the stringing, are rigidly and permanently secured to the handle by means of screws or rivets. In tightening the stringing a knurled head 9 is turned thus rotating a tube 6 and rod 5 provided with left and righthanded screw threads 4, 7 engaging respectively the wedge 3 and the frame 2. The frame 2 is thus pressed upwards and the wedges 3 is drawn down to clamp the frame on its seating and to obtain the requisite tension of the stringing. The wedge 3 and frame 2 are now rigidly and permanently secured to the handle, by means of rivets and screws 10.

Title: Improvements in and relating to screw cutting lathes
IPC: B23G1/02
Filed: 1941-10-27
Abstract: 557,688. Screw-cutting lathes. APPAREILIAGE GARDY SOC. ANON. Oct. 27, 1941, No. 13771. Convention date, Oct. 26, 1940. [Class 83 (iii)] A lathe for turning multiple threads has a oneway coupling in the drive to the lead screw which is momentarily disengaged towards the end of a traverse to produce a change of phase between the mandrel and lead screw to cut another thread on the next traverse. A gear 1 on the workspindle engages a pinion 2 rotatable on a sleeve 3 carrying a ratchet-wheel 5 and also a wheel 4 geared to the lead screw (not shown) operating the tool carriage. The wheel 12 is connected to the ratchet wheel to transmit the drive by a pawl 6 mounted on a pivot 8 and urged towards engaging position by a spring 7. A pin 9 on the pawl engages a slot in a lever 11 pivoted at 12 to the wheel 2. Another lever 15 pivoted at 16 has a projection 14 coacting on the return movement of the carriage with a part 13 on the pawl to disengage the latter from the ratchet. On the forward movement the lever 15 is held inoperative by a spring 17. A rod 18, moving with the tool carriage carries a pivoted tappet 19 for moving the lever 15 towards the wheel 2 at the required time. A latch lever 24 pivoted at 25 is normally held against the lever 13 by a spring 26 and has a recess 27 which is entered by the end of the lever 15 when the latter is actuated by the tappet during the return movement of the tool carriage. When the lever 15 has been thus latched the parts 14, 13, coact to disengage the pawl 6 and thus interrupt the lead screw drive. The ratchet wheel thus slows down while the pawl continues to revolve until the lever 11 unlatches the lever 15 which is then withdrawn by its spring whereupon the pawl 6 drops into the next notch so retarding the lead screw to cut a fresh thread on the next traverse. During the forward movement of the carriage the tappet 19 yields against its spring. The ratchet wheel may be changed for cutting different numbers of threads.

The material 7 then passes over wind boxes 15, the gases being exhausted from the hood 13. The layer 3 may be preheated with an up-draught or inside the hopper 2. Sulphidic lead-bearing ores or ferruginous ores may be sintered by this method.

Title: Device for synchronizing a receiver to the transmitter in a time division multiplex signalling system
IPC: H04J3/06
Filed: 1952-06-10
Abstract: 708,212. Multiplex pulse signalling. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 10, 1952 [June 12, 1951], No. 14613/52. Class 40 (5). [Also in Group XXXV] Relates to means for synchronizing a local pulse generator at a receiver in a multiplex pulse signalling system, in which the channel pulses are time modulated and the synchronizing channel pulses are time modulated, to the maximum extent, by a submultiple of their recurrence frequency to ensure a regular series of pulses immediately following safety intervals t2, Fig. 2, between the channel intervals t1. The locally generated pulses are automatically controlled in frequency and phase so that their trailing edges occur at or very near the commencement of the channel intervals. The incoming pulse train A, in which the synchronizing pulses are shown shaded, is applied to the grid 31, Fig. 1, of a cathode follower valve 32 and the pulses B from the local generator 66 are fed to the grid of the cathode follower 67. The cathodes of valves 32, 67 are connected through condensers 52, 70 respectively to the screen grids of valves 36, 37 respectively, which are connected as a multivibrator having two stable states. Valve 36 is triggered to the non-conducting condition by the trailing edges of the A pulses, while the B pulses have the same action on valve 37 so that the voltage curve C occurs at the anode of valve 36. This voltage is transferred, through the cathode follower valve 53, to be added to the pulses A occurring at the secondary of transformer 34 in the cathode circuit of valve 32, and the composite voltage D thus obtained is clipped and smoothed by circuit 60 ... 65 to provide the control voltage for generator 66. As the pulses C at the anode of valve 36, and the cathode 54 of valve 53, are duration-modulated channel pulses, they may be converted to amplitude modulated pulses in a circuit 71 controlled, in known manner, by the locally-generated pulses from the cathode of valve 67. The amplitudes of pulses A and C are made equal and when pulses B have their trailing edges coinciding with the commencement of the channel intervals, as shown, the composite wave D has the same amplitude and produces no output from circuit 60 ... 65. The same result is produced when the pulses B occur earlier in the safety intervals, curves B1, C1, D1. When. however, pulses B overlap the channel intervals, curves B2, C2, D2 and B3, C3, D3, waves D have portions of double amplitude which are clipped and smoothed by circuit 60 ... 65 to provide the correcting voltage, for generator 66, which increases with the amount of overlap and restores the phase of the B pulses to its desired value.
