Title: Improvements in and relating to internal combustion engines for the automatic regulation of fuel supply thereto
IPC: F02M7/28
Filed: 1923-08-07
Abstract: 205,055. Byrne, C. R., and Buttle, S. R. Oct. 6, J922, [Convention date]. Void [Published under Sect. 91 of the Act]. Spray carburettors.-The fuel supply is controlled automatically in accordance with the temperature of the cooling water, exhaust gases or the cylinder, in such a manner that the fuel delivery is decreased as the temperature increases and vice versa. A casing 6 secured to the cylinder by a bracket 7 contains an expansive device 5, Fig. 4, surrounded by cooling water flowing through pipes 8, 9 connected to the cylinder jacket by a pipe 10 and the radiator by a pipe 11. A disc 17 pressed against the expansive device. by a spring 19 carries a rod 18 which actuates a lever 20, 21 pivoted at 22. The other end 24 of the lever actuates, through a rod 26, one arm of a bell-crank lever 28 the other arm of which may be inserted in any one of a number of holes in a sector plate 35 secured to a spindle 36 which actuates the fuel valve through a spindle 42. The movement of the spindle 36 ie limited by a radius arm 39 working in a slot in a plate 37.

Title: Improvements in or relating to sliding roofs for vehicles
IPC: B60J7/053
Filed: 1945-08-07
Abstract: 596,938. Vehicle opening tops. BISHOP, W. H., and CLEMENTS, W. E. Aug. 7, 1945, No. 20156. [Class 108 (i)] In a vehicle opening-top in which a panel is slidable longitudinally under a fixed canopy, the end of the panel which moves under the canopy is supported for sliding by means of felt or like pads resting freely on longitudinal surfaces at each side of the roof opening and is located in a lateral direction solely by a fixed longitudinal guide member which is mounted at or adjacent to the centre line of the roof opening and passes through a bracket on the underside of the panel. As shown, the opening in the roof is surrounded by a frame 11 formed with a lip 14 and an outwardly-directed flange 15 to prevent ingress of water, and is covered at its rear end by a canopy 13. The sliding panel 10 is guided at its front end by felt-lined sliders 41, Fig. 3, engaging above and below the flanges 15 at the sides of the frame, and is supported at its rear end by felt pads 42, Fig. 4. resting on the flanges. The rear end of the panel is guided by a longitudinal bar 16, Figs. 1 and 5, which is secured between a cross-member at the rear of the frame and a cross-member 17 and engages a bracket 22 secured to the underside of the panel. To minimise friction and prevent rattling, the underside of the panel is provided with a felt layer 24, and the side of the bracket with a fibre layer 25. To lock the panel, the-side of the bar is engaged with the fibre layer by means of a cam 26, operated by a handle 32 on the panel. The linkage connecting the cam and handle carries a plate 36 engaging a crank 37 in a transverse bar 38, Fig. 6, which is formed at its ends with cranked portions'39 adapted to engage ramps 40 on the frame to raise and lower the rear end of the panel. When the panel is unlocked prior to opening, its rear edge is thus lowered to permit sliding under to the canopy, and when the panel is locked in the closed position its rear edge is raised into a position flush with the canopy. The bracket 22 and cam 26 are made of sufficient depth to accommodate this vertical movement. Specification 488,361 is referred to.

A teasel of the type comprising a rotatable body 1 the peripheral surface of which is covered with metal card clothing 2 and having annular end plates 16, 18, is characterized in that the two ends of the body 1 are axially hollowed out at 3, 4 and engage on non-rotatable journals 5, 6 of a support 7 on which the teasel freely rotates, there being provided between the plates 16, 18 and the corresponding sides of the support 7 a clearance of sufficient size to accommodate loose fibres and prevent their being drawn into the cavities 3, 4. The journal 5 is permanently fixed by rivetting on the support 7 whilst the journal 6 is detachably mounted on the support 7 by screwing a part 8 thereof into a threaded aperture 9 in the support or by a thrust spring. The body 1 may be made of wood and has an axial bore 11 extending therethrough of slightly smaller diameter than that of the cavities 3, 4 to form shoulders facilitating the positioning of the body 1 on the support 7. The bore 11 has the same diameter as bores 12, 13 in the journals 5, 6, respectively. The plates 16,18 each have a stamped part 17 fitted with a force fit into the cavity 3 or 4.

Patent GB-407592-A (GB)
Title: Improvements in or relating to methods for the electrical signalling of instrument readings
IPC: H04Q9/04
Filed: 1933-07-19
Abstract: 407,592. Electric signalling systems. CHAUVEAU, L. L. E., 79, Boulevard Haussmann, Paris. July 19, 1933, No. 20383. Convention date, Aug. 1, 1932. [Class 40 (i).] In a system for transmitting instrument readings to a remote point, the pointer of the instrument, which normally swings freely above a series of contacts, is moved to make contact with one of the contacts and a step-bystep switch hunts for the marked terminal, a similar switch at the remote point stepping in synchronism and moving a pointer over a suitable dial. The two switches are stopped when the marked position is reached, a manually operated resetting switch being provided to release the apparatus whereupon the switches step to their normal positions. The switch at the transmitting point has fewer positions than the receiving switch so that it reaches its home position first. Several instruments are connected to the signalling equipment, the initial steps of the switches selecting the appropriate equipment. As shown in the Figure the readings of either of the two instruments A1, A2 can be indicated on IND. To initiate the transmission of the reading of A1, key B1 is depressed and RB1 pulls up. AMC and AMI which are normally energized, release and MI and MC step over parallel circuits, MI interrupting the circuits to produce step-by-step movement. On the first step both IND and CH contact with terminals A, CBI pulls up, RB1 releases and E1 energizes and locks over F1, F3. Magnet E1 moves pointer A1 into contact with the terminal bank. The switches continue to step until CH reaches terminal 7 which is marked by A1 when MC and MI are shorted out and the switches stop. IND then indicates the reading of A1. To reset the apparatus key Zero is depressed momentarily, E1 1 releases and MI and MC continue stepping. When CH reaches its home contact 0, AMC energizes, closing the circuit to AMI and opening that to MC. MI continues stepping until IND reaches its home position when AMI pulls up to break the stepping circuit. If the reading of A2 is required key B2 is depressed, RB2 pulls up and CB2 and E2 energize over B instead of CB1 and E over A. The remainder of the operation is identical to that described above.
