Title: Improvements in or relating to chronographic counter mechanism
IPC: G04F7/04
Filed: 1931-03-19
Abstract: 362,287. Stop-watches. AMIDA SOC. ANON., 50, Kapellstrasse, Grenchen, Soleure, Switzerland. March 19, 1931, No. 8536. Convention date, Aug. 26, 1930. [Class 139.] In a watch chronograph of the type comprising an independent seconds wheel adapted to drive a counter wheel and heart-shaped cams actuated by a detent rocker to reset the seconds and counter wheels, the elements which establish (1) the transmission from the watch movement to the seconds wheel 10 and (2) the transmission from the seconds wheel 10 to the counter wheel 13, consist of gear wheels 21, 17 pivoted on a lever 19 which may be rocked about its pivot 20 to make and break both transmissions without the necessity of zeroizing the seconds and counter wheels. In (2) the gear wheel 17 is rigid with a star wheel 16 actuated by a finger 15 moved by the seconds wheel 10. The pinion 5 on the winding stem is controlled by knob 4 in the usual way, either engaging the crown wheel 6 or being depressed for hand setting. In the present case this axial depression rocks a lever 7 which in turn rocks a lever 23, pivoted at 24, against spring 25 so that lugs on this lever zeroize the hearts 11, 14 on the seconds and counter wheels. When wheel 21, which is constantly driven from the watch movement, is driving seconds wheel 10, the latter through finger 15 is driving the counter wheel 13. If lever 19 is moved in the direction of the arrow by a friction slider on the shoulder portion of the case, wheels 21, 10 and 17, 13 are demeshed. On return of lever 19, wheels 10, 13 resume their motion from the last position. If zeroizing be desired, the transmissions are broken before knob 4 is depressed.

Filed: 1924-04-04
Abstract: 213,926. Zima, V. April 6, 1923, [Convention date]. Variable-speed gearing. -An epicyclic train is controlled by a governor which varies the amount of friction internal to the train, and in consequence the speed ratio. Planet pinions h, Fig. 2, carried by the driven shaft b mesh with an internally-toothed gear F, which is held by a brake G when the drive is connected. The pinions h mesh also with a sun gear e<1> fast on the driving-shaft a and with a like gear e<2> fast on a sleeve i, which is loose on the shaft a. The sleeve i and shaft a are connected by governing means shown in Fig. 3, which forces the sleeve to turn relatively to the shaft, and so produces a jamming or grinding action in the epicyclic train with braking effect. Centrifugal levers n mounted on one part acts directly on projections on a disc L on the other part.

Title: Improvements in automatic tuning apparatus for wireless receivers
IPC: H03J7/04
Filed: 1937-03-24
Abstract: 494,577. Valve circuits for wireless reception. ROBINSON, J. March 24, 1937, Nos. 8738, 13417, and 23565. [Class 40 (v)] Oscillations at the true intermediate-frequency produced by an additional oscillator are combined with the incoming signals to produce the true local-oscillator frequency which is fed back to control the normal local oscillator. In one arrangement, Fig. 1, the amplified signal frequencies in addition to being supplied to the normal frequency changer 13 are amplified and combined in a second frequency changer 22 with intermediate-frequency oscillations produced in a crystal-controlled circuit 23. The output is fed over lead 26 to the tuned circuit 14, 15 of the normal local oscillator. The incoming carrier-frequency also appears in lead 26 and is fed back through valve 13 to augment the incoming carrier to increase selectivity. In another arrangement, Fig. 2, the intermediate - frequency produced in frequency changer 41 is amplified at 44 and applied to a grid 45b of a second frequency changer 45, oscillations of the true intermediate-frequency being produced at the same grid by a tuned circuit 46. The local-oscillator tuned circuit 42 is connected to another grid 45a of valve 45 and the output of the valve includes both the intermediate frequency and the original frequency. By reason of electron coupling, the incoming frequency appears on grid 41b of valve 41 and is fed over lead 48 to valve 45 in which it combines with the intermediate frequency to produce a local-oscillation frequency which is fed back over lead 48 to control the local oscillator 42. There is also produced in valve 45, by combination of local oscillations and intermediate-frequency oscillations, the original signal frequency which is fed back over lead 48 and valve 41 to augment the incoming signals to increase selectivity. The system may operate with the circuits in a condition of sustained oscillation and this condition may be controlled by A.V.C. means so that the circuit is retroactive but non-oscillating except when in tune. Normal A.V.C. control or meeting of the output circuit may be employed. Specification 466,415 is referred to. Specification 489,571 also is referred to in the first Provisional Specification.

Title: Improvements in or relating to the polymerisation of styrene or of its polymerisablederivatives
IPC: C08F2/36
Filed: 1942-06-25
Abstract: Styrene (or a derivative) is polymerized by heating in the presence of an oxy-compound of boron and oxalic acid or a derivative thereof. Styrene derivatives include o-, m- and p-alkyl substituted styrenes, a - and b -alkyl styrenes, halogen substituted styrenes, and phenyl, hydroxy and methoxy styrenes. Oxy-compounds of boron include acids of boron, e.g. H3BO3 and HBO2, oxides, e.g. B2O3, metallic borates, e.g. (MnH4(BO3)2, organic borates having an alkyl, alkinyl or aromatic group, e.g. triamyl, triallyl or triphenyl borates and alkali borates, e.g. Na2B4O7 and NH4B4O7.  Oxalic acid derivatives specified are the mono- and di-alkyl, aryl and alkenyl or other hydrocarbon radical esters.  Polymerization may be carried out by heating the mixture of monomer and catalysts, or one component of the catalyst may be incorporated with the monomer and the polymerization carried out in situ by addition of the second component.  In the latter manner, gaskets, coatings, cast mouldings and jointing compounds may be obtained.  Preferably, the polymerization is carried out by introducing the monomer into the heated liquid polymer which contains the catalyst.  The process may be carried out continuously by passage of the monomer and catalyst mixture through a long helix of metal tubing immersed in a constant temperature bath.  The products are useful as components of lacquers, varnishes, adhesives, films and moulding compositions.  They are compatible with ethyl cellulose, ester gums, natural or synthetic resins, aliphatic and aromatic plasticizers and solvents.  They are soluble in drying oils, tung, oiticica, linseed and dehydrated castor oils, and in petroleum oils. In examples, a catalyst mixture of boric and oxalic acids was used to polymerize (1) styrene, and (2) a -methyl p-methyl styrene.  A catalyst comprising triamyl borate and oxalic acid was used to polymerize (3) styrene, (4) a -methyl styrene, and (5) monochloro-styrene.  Styrene was also polymerized by catalysts comprising (A) boric acid and diethyl oxalate, and mixtures of oxalic acid with (B) B2O3 and (C) manganese borate. In example 10, a mixture of monostyrene, oxalic acid and a small amount of triamyl borate was polymerized by addition to a still containing the heated polymer and triamyl borate.  Specification 549,303 is referred to.

Title: Improvements in safes and the like
IPC: E05G1/10
Filed: 1923-03-28
Abstract: 213,118. Whittingham, C. H. March 28,1923. Safes; locks operating alarms; multiple fastenings. -The multiple bolt of a safe door is blocked by the bolt of a keylock which in its fully shot position closes a switch so that on either shooting the bolt beyond its normal fastening position against a spring, or on attempting to force the door, contacts are made which result in the ringing of an alarm. Fig. 1 shows the way in which the alarm bell 10 carried by the safe door is connected to the battery 14 and the contact switches 6, 12, 22. The bolt 3 with an arm 3a is shown in its normal fastening position, a spring 7 holding it against further forward movement unless forced. The bolt 3 is blocked by the bolt of the key lock 4 taking into the recess 5. One turn of the key of the lock 4 blocks the bolt 3, two turns also closes the switch 12. When the switch 12 is closed and the bolt is forced forward against the spring 7, the contact switch 6 is closed and the current passes up the lead 8 to the bell terminal 9, through the bell-coil to the terminal 11. through the lead 27 to the terminal 12, through the lead 28 to the battery pole 13, through the battery to pole 15 and through the lead 29 back to the contact switch 6. As the current passed through the coil of the bell, the armature carrying the clapper was attracted, releasing the member 30 which then made a contact with the terminal 20 to complete the continuous bell ringing circuit, as follows, terminal 20, lead 19, battery pole 15, battery, pole 13, lead 28, terminal 12, lead 27, terminal 11, bell-coil, back to terminal 20. The door 2 is held by a spring 26 so that a contact switch 22 similar to 6 is adjacent to a part 23 in the frame. On forcing the door inwards against the spring 26, the switch 22 is closed and the alarm bell rings, the continuous belt ringing circuit being again completed. On closing the switch 22. the current passes through the lead 24 to the bell terminal 9, through the bellcoil to terminal 11, through the lead 27 to terminal 12, through the lead 28 to terminal 13 of the battery, through the battery to terminal 15, through the lead 25 back to the switch 22. The bell 10 and battery 14 are mounted on the insides of hinged flaps 17, 18 respectively for ease of renewal. Fire-resisting material 16 surrounds battery bell.

Abstract: 996,395. Parking brakes for trailers. SCAMMELL LORRIES Ltd. March 3, 1964 [June 5, 1963], No. 8841/64. Divided out of 996,394. Heading F2E. A braking system for the trailer unit 4 of an articulated motor vehicle provided with a supporting device which can be changed from a trailer supporting position (Fig. 1) to a stowed position (Fig. 4) has means movable in response to the said change of position to energize a spring 38 and simultaneously release brakes acting on the wheels (not shown) of the trailer. The supporting device is as described in Specification 996,394 and comprises a pair of legs 1 on a transverse axle 2 pivotally secured to a turntable 3 on the trailer 4 by brackets 5. Each leg has an axle 6 carrying two wheels 7. Linked levers 8, 9 connect the legs to a pivot 11 on the turntable 3 and are moved from the supporting to the stowed position and vice-versa against the force of a spring 15. Catches (not shown) retain the legs in either position. Parallel members 26 extend back and down from the turntable 3 and carry on a pivot between them (see Fig. 2) a link 36 having a tail formed as a cam surface to engage a roller 37 carried on one of the upper levers 8 and a head carrying a shaft 39 which bears on a collar 40 which is loaded by the spring 38. The shaft 39 is adjustable by means of a nut 43. When the trailer is being supported by the device and it is wished to couple it to the tractor the latter is reversed towards the trailer unit until a pair of ramps 32 on the tractor engage rollers (not shown) pivoted at 12 on the lever linkage. A member 19 on the tractor then engages a plate 18 to release a catch which holds the device in the supporting position. Continued movement of the tractor then raises the legs 1 until they reach the stowed position as in Fig. 4. During the upward movement of the link 8 the roller 37 contacts the link 36 causing it to pivot and compress the spring 38 between the collar 40 and a fixed, apertured plate 41 through which passes the shaft 39 on which the collar 40 is mounted. The shaft 39 connects through linkage 42, 44 with the trailer brakes which are released in consequence of the compression of the spring 38. An alternative linkage is provided to allow the trailer brakes to be applied from the driver's cabin without affecting the braking system described here. When the legs are again lowered the spring 38 is freed to bear on the collar 40, thereby applying the brakes.
