Title: Improvements in flasher units intended for fitting mainly to road vehicles
IPC: B60Q1/38
Filed: 1967-06-15
Abstract: 1,137,445. Vehicle flasher units. G. CARTIER. 15 June, 1967 [5 Dec., 1966], No. 27661/67. Heading G4Q. [Also in Division H1] A flasher for road vehicles comprises a thermally responsive control device mechanically connected through lost motion to a bi-stable snap-action switch which in one position connects the lamps to the source via the control device and a solenoid for a pilot lamp, and in the other position by-passes the control device, the switch being operated by alternate heating and cooling of the control device. Provision may be made for emergency flashing of all lights. When the direction switch 5 (Fig. 1) is set to position 7 or 9 to flash lamps 1/2 or 3/4 respectively, current flows from source 10 through contacts 23/40, the thermally-extensible wire 19, spring blade 15, terminal 11 and switch 5 to the lamps; the resistance of the wire 19, however, reduces the current below that necessary to light the lamps. As the wire 19 lengthens, the elasticity of the blade 15, which is fastened to the wire at 18, pulls this end downwards, and a fork 34 trips the tumbler 21. The tumbler (Fig. 6) comprises a cylindrical or part cylindrical spring 29 having slots which engage lugs 26, 27 on a flexible metal blade 22 which is cut out to leave a tongue 25. The fork 34 engages this tongue and has a slot 36 so that a certain amount of downwards motion of the fork is necessary before the tongue is moved. When the latter is pushed down by a predetermined distance the spring clicks over to a new stable position holding the end of the tongue 25 below the plane of the blade 22. The latter therefore clicks upwards and contacts 23/40 (Fig. 1) are disengaged while further contacts 33/42 are made. The wire 19 and blade 15 are now taken out of circuit and current flows through a solenoid 43 to light the lamps at full brilliance. The solenoid attracts an armature 45 upwards to close contacts 40/46 (Fig. 2, not shown) and light a pilot lamp 14 through the wire 19 and blade 15. The pilot lamp current is insufficient to keep the wire 19 hot, and as it cools the fork 34 is drawn upwards, until contacts 33/42 open to extinguish the pilot lamp by de-energizing solenoid 43 (Fig. 3, not shown). Further raising of the fork 34 trips the tumbler switch back to its original position and the cycle re-commences. An audible warning of flashing is given by the armature 45 striking a fixed stop 47 when the solenoid is de-energized. For emergency flashing of all four lights 1-4, a switch 12 is operated, and a separate repeater 52 then flashes.

Title: Process for the production of homogeneous copolymers
IPC: C08F10/00
Filed: 1960-08-16
Abstract: A process for the copolymerization of two or more alpha-olefins, at least one of which polymerizes at a different rate from another of the olefins, comprises initiating the copolymerization with a first feed containing a ratio of monomers selected to produce a copolymer of desired composition and continuing the copolymerization while maintaining the monomer ratio constant by introducing a second feed containing the monomers in a ratio corresponding to the relative rates of consumption or reaction of said monomers and at a rate sufficient to maintain a constant concentration of monomers in the reaction zone. Specified monomers are ethylene, propylene, butene, pentene, heptene, octene, dodecene, tetradecene, hexadecene, methylbutene, methylpentene, methylhexene, butadiene, isoprene, piperylene, and cyclopentadiene and minor amounts of tetrafluoroethylene and fluoro-chloro-ethylene as comonomers.  The catalysts suitable for the copolymerization are preformed transition metals as elements or oxides on high surface area supports (e.g. nickel on charcoal or chromia on silica-alumina), promoted transition oxide catalyst (e.g. chromia-alumina and aluminium trialkyl), solid catalysts precipitated in situ from transition metal salts and organo metallics (e.g. titanium tetrachloride + aluminium trialkyl), and pretreated precipitated catalysts in combination with organometallic compounds (e.g. titanium trichloride + aluminium trialkyl).  Many catalysts are listed and in the examples there is used sodium promoted molybdena/alumina in a mineral spirits medium.  The polymerization may be continuous or semi-batch, and the second feed may be in correct proportion in response to a monitored reaction zone composition analysis. The examples illustrate initial and second feeds for ethylene/propylene and ethylene/butene copolymerizations. The products have macroscopic and microscopic homogeneity.

Abstract: 428,768. Fluid-pressure brakes. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Oct. 14, 1933, No. 28450. Convention date, Oct. 15, 1932. Hydraulic transmission more particularly for motor vehicle brakes comprising a manually and a power-operated cylinder 12, 10 respectively is provided with a normally closed check valve 36 arranged at the discharge end of the power operated cylinder. The piston 32 of the cylinder 12 is connected to the piston 96 of a vacuum operated cylinder 16, normally having vacuum on both sides of the piston and controlled by a valve 17 operated by lever 152 and lever 116 connected to the brake pedal. Operation of the valve 17 to admit air to one side of the piston 96 moves the piston 32 to force liquid past the check valve 36 into cylinder 10 and through a connection 22 to the brakes to apply the brake shoes to the brake drum. Liquid also passes from cylinder 12 to cylinder 10 through a byepass not shown in Fig. 1 which is covered by initial movement of the piston 18. This byepass and port 70 in cylinder 12 serve to replenish the brake system from the reservoir 14. Braking pressure is applied manually by the piston 18 which is operated by a connection 120 from the lever 116. The vacuum control valve comprises a valve 148 normally closing an atmospheric opening 144 and a valve 164 normally held open to connect chambers 130, 131 each connected to one side of the cylinder 16. Chamber 131 has a connection 136 to a source of vacuum. Operation of lever 152 releases valve rod 150 which is moved by spring 156 to close valve 164 and open valve 148 thus connecting one side of piston 96 to atmosphere. A check valve 140 is provided in the vacuum connection 136. In bleeding the system the brake pedal is operated sufficiently to open and close the valve 17 to reciprocate the piston 32 and pump liquid to the lines from the reservoir 14 through a check valve 74. The piston rod 98 passes through two packings 46, 102 having a chamber 108 between connected to atmosphere in order to prevent liquid being sucked from the cylinder 12 to the cylinder 16. In a modification of the invention the vacuum piston is operated by connecting one side to vacuum, and the cylinders 10, 12 are connected by a port in alignment with the port 70. In a further modification shown in Fig. 6, the cylinders 310, 312 are in alignment. The reservoir is connected to the cylinder 310 by a port 356 closed by a valve 355 operated by vacuum piston 396 when the brake is applied. The reservoir is connected to the cylinder 312 by a port 370 and also a port 378 and inclined passages 375 when the edge of the rubber cup 376 is raised by the return movement of the piston 332. The piston 332 forces fluid to the brakes by means of straight passages in the valve 374 and past the valve 336. In a further modification the valve 355 is omitted.
