Title: Improvements in or relating to change speed gears with free run device, more particularly for power driven vehicles
IPC: F16H3/08
Filed: 1933-08-14
Abstract: 409,184. Variable-speed gearing. ZAHNRADFABRIK FRIEDRICHSHAFEN, AKT.-GES., Friedrichshafen-on-Bodensee, Germany. Aug. 14, 1933, No. 22661. Convention date, Aug. 29, 1932. [Class 80 (ii).] Relates to constant mesh gears of the kind in which gear wheels 5, 6, 7 are mounted in bearings in the casing and can be brought into action by toothed clutches 20, 21 provided with synchronizing friction clutches 11 .... 15, the main shafts being arranged coaxially within the gears ; a free-wheel 31 also is provided. According to the invention, direct drive is obtained by shifting an intermediate shaft 3 which is in permanent engagement, either directly or through the free-wheel, with one of the main shafts. As shown, the shaft 3 engages the inner member 32 of the free-wheel, and carries teeth 54 adapted to engage teeth 53 on the driving-shaft 1 when the shaft 3 is slid fully to the right, thus giving the direct drive to the driven shaft 2. For low speed, the shaft 3 is shifted to the left to engage the gear 7, and the clutch 20 is shifted to the left to engage the gear 5, so that the drive is through the gears 5, 23, 25 and 7. For second speed, the clutch 20 is shifted to the right, so that the drive is through the gears 6, 24, 25, and 7. For third speed, the clutch 20 is shifted to the left, the clutch 21 to the right, and the shaft 3 sufficiently to the right to disengage it from the gear 7, so that the drive is through gears 5, 23, 24, and 6, and shaft 3. For reverse, the countershaft 28 is slid to the right, so that the gear 26 thereon engages the gear 25 on the countershaft 22, while the gear 27 engages teeth 29 on the outside of the member 31, thus bridging the free-wheel.

Title: Improvements in or relating to electrically operated supervisory systems for railwaysignals
IPC: B61L1/16
Filed: 1935-08-12
Abstract: 447,008. Railway signalling systems. VEREINIGTE EISENBAHN - SIGNALWERKE GES., Siemensstadt, Berlin. Aug. 12, 1935, No. 22688. Convention date, Sept. 10, 1934. [Class 105] A lock magnet on a signal lever can only be re-energized to permit the re-setting of the signal to " clear " if a train has entered and operated an axle-counting mechanism first to count in the axles and later to count out the same number of axles. If the signal should be returned to danger without a train having entered, an emergency key must be operated to set up the normal conditions again. The apparatus shown comprises an axle-counting mechanism Z 1, Z2, a lock relay 3 and two control relays 1, 2 of which the relay 2 is energized by a stick circuit and the relay 1 is de-energized in the normal state, the axle-counting mechanism being at zero so that its lower contact ZO is closed. On closing a catch-handle contact H, the relay 1 is picked up over the lower, i.e. zero contact Z0, the contact H, a front contact 23 of the stick relay 2 and a signal lever contact S. The opening of the back contact 11 of the relay 1 breaks the stick circuit for the relay 2 which therefore drops so completing a stick circuit for the relay 1 over front contact 12, back contact 22 and lever contact S. The lock magnet 3 can now be energized over the zero contact Z0, the catch-handle contact H, back contact 23 and front contact 13. On moving the lever over to set the signal at clear, the contact S opens and breaks the stick circuit of the relay 1 so that both relays 1, 2 are now de-energized. The signal cannot be re-set to the clear position until the relay 2 has been re-energized and to effect this it is necessary for the train to enter the section and operate the axle-counting mechanism thereby to close the upper, i.e. non-zero contact Z0 whereby the relay 2 is picked up and thereafter sticks over its own front contact 21 and back contact 11. Shunting signals or signals for converging tracks may be controlled by the apparatus, the signals being interlocked by the contacts S being arranged in series and the contacts H being arranged in parallel.

Abstract: 765,120. Seaming. IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 13, 1955 [Aug. 6, 1954], No. 22925/54. Class 42 (1). Two or more layers of film of an organic thermoplastic material are seamed together by supporting them on a continuously moving solid surface and, while maintaining a longitudinal tension in the film, continuously pressing upon the superposed layers a narrow metal element held substantially stationary with its longitudinal axis parallel to the direction of travel of the film; the metal element is heated to a temperature such that the film melts at the region of contact with the element and the element passes through the layers; the separate lengths of seamed film are thereafter withdrawn from each side of the heated element. As shown, the solid supporting surface is a rotating steel roll 1 and tension is induced in the film layers 15, 16 by slightly braking the supply rolls 4, 5. Each of a series of heating elements consists of a resistance wire 6 mounted on a spring steel strip 11 carried on a swivel arm 7 ; or each heating element may consist of an electrically heated metal block having a longitudinal ridge projecting from its lower surface. The process may be used to produce tubular film by seaming together the free edges of a continuous folded length of film, or by seaming and separating film layers along two or more parallel lines. The solid supporting surface may be treated with a lubricant, e.g. polytetrafluoroethylene or silicone resins, or may be faced with a film of the lubricant or with glass cloth coated or impregnated with the lubricant. The film material may be polythene, polyvinylidene chloride, rubber hydrochloride or linear superpolyamides or superpolyesters; polyethylene terephthalate is stated to be particularly suitable.

Title: Improvements in or relating to protective control systems for electric motors
IPC: H02H7/00
Filed: 1933-08-17
Abstract: 418,615. Protective cut-out arrangements and automatic circuit-breakers; control of motors. BROOKE, W., Braemar, Laburnum Lane, Hale, Cheshire. Aug. 17, 1933, No. 22964. [Classes 38 (iii) and 38 (v).] In a remote control system for an electric motor B, operating a coal cutter &c., and connected by a trailing cable U to control mechanism A and supply lines L<1>, L<2>, L<3>, the motor supply circuit is opened if connection is made between the pilot core Y and earth core Z other than by closure of an operating switch G, by associating opposed rectifiers m, n and inductances h<1>, h<2> with the energizing circuit of a relay k which initiates operation of the main motor contactor C. Closure of operating switch G energizes relay k with direct current from a transformer g thereby completing the energizing circuit of a relay f whose contacts r are included in the energizing circuit of the main contactor coil d. In closing, the main contactor C opens auxiliary contacts c<5> included in its energizing circuit, but is retained closed by a mechanical catch associated with relay f as long as the latter remains closed. If a short circuit occurs between cores Y and Z, alternating current is supplied to contactor coil k but is suppressed sufficiently to prevent operation (by inductances h<1>, h<2>). The contacts c<1>, c<2>, c<3> of contactor C are carried on a pivoted arm 20, Fig. 3, having an extension connected with toggle links 29, 30 co-operating with a pivoted lever 33 engaged through a spring 37 by the moving member 36 of contactor f. When contactor f is energized, the spring 37 is strained so that when contactor C closes, an extension 33<a> on lever 33 retaining the links 29, 30 in the extended position until contactor f is deenergized. Switch G may be retractive, and its circuit maintained through the contacts of an electromagnetic switch energized from two of the motor supply leads, so that, in the event of the supply failing, the motor does not start with the resumption of the supply until the switch is operated.
