Title: Improvements in variable speed gear
IPC: F16H3/10
Filed: 1929-04-02
Abstract: 309,078. Krupp Akt.-Ges., F. April 4, 1928, [Convention date]. Addition to 292,549 and 297,793. Variable-speed gearing comprises a development of the arrangement suitable for Diesel locomotives described in Specification 297,793 in which there is a single large friction clutch which serves for speeding up claw-clutch elements for different speeds, a ratchet clutch overrunning as a higher speed become effective, the friction clutch being superseded by the claw clutch. In this invention, claw clutches which were on the engine side of the friction clutch are now arranged in the change-speed gear itself, and are shown at d<4>, b<5>. There is a driving-shaft A connected through a clutch casing A<3> and a spring Q to a collar b<4> fast on a shaft B, which is thus driven resiliently, and a driven shaft C. The shaft C is driven at three ratios corresponding to the pair F, c', the pair d<1>, H, and the pair E, J, and at a fourth very low speed through train d', H, J, E, F, c<1>. There are ratchet clutches which yield on passing to a higher speed by temporary use of the friction clutch N, which is fast on a sleeve N<1>, and is adapted to be gripped between friction rings a<4> carried by casing A<3>. A spring Q<1> connects casing A<3> to a loose claw clutch P. In the position shown, with the friction clutch and all claw clutches disengaged, the parts A, A<3>, a<4>, P, b<4>, B, b<5> alone are rotating. To bring pair F, C' into operation, clutch n<3>, G is engaged and afterwards the friction clutch N, a<4>. The drive passes through train A<3>, a<4>, N, N<1>, n<3>, G, ratchet, g<1>, E, ratchet, f<1>, F, c<1>. When the friction clutch halves are rotating at equal speeds, clutch b', G is thrown in, and clutch n<3>, G and the friction clutch are thrown out. Power then passes resiliently through train A<3>, Q, b<4>, B, b<5>, G, g', E, f<1>, F, c<1>, and the friction clutch disc N comes to rest. Each passage to a higher speed is effected by its proper combination of clutch operations.

Title: Improvements in or relating to monostable electric circuits employing transistors
IPC: H03K3/284
Filed: 1961-03-21
Abstract: 943,043. Transistor monostable circuits. GENERAL ELECTRIC CO. Ltd., and A. G. BLAY. March 21, 1962 [March 21, 1961], No. 10353/61. Heading H3T. In a monostable circuit comprising two reciprocally cross-coupled transistors 1, 2 of similar conductivity type, transistor 1 being non-conducting and transistor 2 being conducting in the stable state and the cross-coupling from transistor 2 to transistor 1 being effected through emitter-follower transistor 8 of opposite connuctivity type, the timing circuit comprising resistor 29 and capacitor 30 which determines the duration of the unstable state in which transistor 1 is conducting and transistor 2 is non-conducting is coupled to the base electrode of transistor 2 through a rectifier diode 28 which is poled so as to be non-conducting when the circuit is in the unstable state so as to prevent temperature-dependent leakage currents in transistor 2 from flowing into capacitor 30 and thus maintain the duration of the unstable state independent of temperature variations. In the rest condition of the circuit transistors 2, 8 and 15 are conducting and transistor 1 non-conducting, supply line 13 being 10 volts positive to earth line 6 and lines 17 and 19 being respectively 20 and 10 volts negative to earth. The application of a negative pulse at terminal 3 renders transistor 1 conducting and the potential at its collector electrode rises switching off transistors 2 and 15. The potential at the collector of transistor 2 falls from the value previously maintained by Zener diode 20 to- 10 volts and a corresponding fall at the emitter of transistor 8 serves to maintain transistor 1 conducting. As a result of the rise in potential of the collector of transistor 15, the junction point of capacitor 30 and resistor 29 rises sharply, cutting off diode 28 as the base of transistor 2 is held close to earth potential by diode 24. Capacitor 30 then discharges until the potential at its junction with resistor 29 goes negative, whereupon diode 28 conducts and transistor 2 is switched on again. This switches transistors 8 and 15 on and transistor 1 off to restore the quiescent state, transistor 15 providing a rapid recharge path for the capacitor 30.

Patent GB-644666-A (GB)
Title: Improvements in housing machines for joinery work
IPC: B27F5/02
Filed: 1948-04-14
Abstract: 644,666. Housing machines; circular saws ; grinding machines. DICKS, P. A. April 14, 1948, No. 10418. [Classes 60, 145 (i) and 145(ii)] A housing machine, of the type having a track, means for securing work to the track, a carriage which can be moved along the track and which carries a rotary cutter driven by an electric motor, means being fitted to adjust the height of the cutter with reference to the work, has a trigger switch to open or close the circuit of the electric motor and a locking device to prevent the switch being closed when the cutter is in or on the work. A housing, carrying a cutter disc 11 driven by an electric motor, is pivoted at 15 to a carriage plate 16 which slides in slotted track rails 17 on the workpiece, the penetration of the cutter into the workpiece being limited by an adjusting screw 18. A micro-switch 20, mounted in the handle 21, is operated by means of a trigger 27, the upper part 29 of which moves the rod 24 and plunger 23 axially and so depresses the operating knob 22 and closes the switch. A pillar 30, mounted on the carriage plate 16 and projecting into the recess 31 in the handle 21, carries at its upper end a keeper 33 pivotally mounted in a recess 34 and kept perpendicular to the pillar by a spring. When the cutter is in the raised position the trigger 27 may be operated thus closing the micro-switch 20. As the cutter is then lowered on to the work the tail 32 of the trigger depresses the keeper 33 against the action of its spring. If, however, an attempt is made to operate the trigger when the cutter is in the lowered position, the keeper 33 which is at right angles to the pillar 30 prevents movement of the trigger and thus the cutter cannot be started. For locking the housing in the raised position, a spring-loaded pin 36, having a head 38, is mounted in the housing so that, when the pin is depressed, a slot 40 in the pin engages with the recess 34 and lowering of the housing is prevented. The cutter may be of the type having one or more cutting blades projecting from a rotary disc, or an abrasive wheel or a rotary saw.

Title: Improvements in or relating to looms for weaving
IPC: D03D51/00
Filed: 1954-04-10
Abstract: 760,979. Loom take-up and let-off motions. STOBBS, J. V. March 24, 1955 [April 10, 1954], No. 10612/54. Class 142 (2). On weft failure, mechanism operated by a reciprocating bar on the slay forming part of a weft stop-motion interrupts the take-up and let-off motions. During normal weaving a ratchet-wheel 1 connected to the take-up and let-off motions is moved by a pawl 2 and is retained by a catch 3. Upon weft failure, a reciprocating bar 13 is positioned by the weft stop-motion so that at beat-up it lifts an arm 7 pivoted on the catch 3 and by means of a spring 11 raises the catch 3. Movement of the catch 3 is limited by a projection 12 thereon engaging an adjustable stirrup 16. Further movement of the slay and arm 7 extends the spring. When the slay moves back, the arm 7 is lowered by the spring and the wheel 1 returns to its original position, after being moved by the pawl 2, since the catch 3 is raised. Finally, the catch 3 is lowered and re-engages the tooth on the wheel 1 from which it was raised so that neither the take-up nor the let-off have been operated. The weft stop motion knocks off the loom.

Title: Improvements in surface treatments for metallic articles
Inventor: LLEWELYN GEIRIONYDD
IPC: C23C10/52
Filed: 1956-04-06
Abstract: A surface treatment for an article having a finished surface and made from a metal or alloy which is subject to intergranular oxide penetration comprises heating said article in contact with a powdered alloy containing not less than 15 per cent Ti and not less than 6 per cent Al in an atmosphere which is inert to the metals of which the article and powdered alloy are composed, the article being heated at a temperature above its normal maximum working temperature for a time sufficient to form a modified layer on the surface thereof, and being thereafter cooled.  The article may be made of ferrous metal, e.g. mild steel, Ti-base alloy, Mo-base alloy, Ni-base alloy, or Co-base alloy an example of which is composed of C 0.5 per cent, Cr 28.0 per cent, W 7.5 per cent, Ni 12.0 per cent, Co the remainder.  The powdered alloy should have a fineness of 100-16 mesh/inch, and may be an Fe-Ti hardener, e.g. consisting of Ti 33.6 per cent, Mn 1.4 per cent, Si 1.2 per cent, Al 16.9 per cent, Fe the remainder, or an Ni-Ti hardener, e.g. consisting of Ti 43.4 per cent, Mn 3.7 per cent, Si 3.3 per cent, Al 9.3 per cent, Fe 0.36 per cent, Co 0.51 per cent, Ni the remainder.  The surface treatment may be carried out (1) by packing the article together with powder in a heat-resisting box and passing A or H2 therethrough, or (2) by applying a removable coating of the powder, made for example by mixing the powder with a bonding medium, and then heating in an inert atmosphere.  Where the article is made of an alloy which would normally be subjected to a solution heat treatment, it is heated in the powder to a temperature approximately that of said heat treatment, e.g. for an Ni-base alloy, this could be 1000-1190 DEG C. Following the surface treatment, the article may be aged, e.g. by heating at 690-710 DEG C. for 12-16 hours and cooling in air in the case of Ni-base alloy.
