Title: Improvements in or relating to carburettors
IPC: F02M23/09
Filed: 1929-06-27
Abstract: 314,989. Bosch Akt.-Ges., R., (Assignees of Sturm, W.). July-7, 1928; [Convention date]. Spray carburettors. - In carburettors, such for example as described in Specification 287,902, having a manually - controlled air or mixture throttle, and in which all or part of the air flow is regulated by an automatic valve, the automatic valve is adapted to be maintained completely or partly open when the throttle is closed. The carburettor b, Fig. 1, has a hand-controlled air throttle a, a choke tube f in communication through a tube d with the air space in the float-chamber c, and another choke tube g discharging into the tube f and receiving fuel from a pipe e. A duct h at the side of the choke tubes is provided with an automatic valve i which is normally closed, but is opened as the suction increases. At the point where this valve seats, an inlet k is provided through which, when the throttle a is closed, a current of air is drawn which opens the valve i and prevents violent and harmful movement of said valve. In a modification, Fig. 2, the valve a is a mixture throttle, and the valve i is located in the air inlet and is mounted on a spindle n which carries a vane q located in a chamber o. The space r on one side of this vane communicates through a tube m with the engine side of the throttle valve, whilst the space s on the other side of the vane is open to atmosphere. When the throttle a is closed, the valve i is moved to its open position by suction transmitted to the vane, which acts also as a damping means. In a modification of this construction, the valve i and its actuating means are placed at the side of the choke tube f instead of below it. The Specification as open to inspection under Sect. 91 (3) (a) describes also a still further modification, Fig. 5 (Cancelled), in which the valve i is opened positively from throttle a through linkage w, v, and a pin u engaging a notched arm on the spindle n, but this connection becomes inoperative as soon as the valve a has been opened. This subject-matter does not appear in the Specification as accepted.

Abstract: Thermoplastic synthetic unoriented filaments particularly substandard filaments, are stretched to improve their quality (such that they may be cut into uniform length staple fibres and spun into yarn) by winding a number of ends of the filaments in a spool in an accumulated strand having a total denier of 50,000 to 1,000,000, e.g. 350,000, leading a strand from each of a number of such spools separately through the nips of a series of three pairs of very heavy superposed rollers, rotating the second pair of rollers at a higher peripheral speed than the first and the third at a higher peripheral speed than the second, condensing the stretched strands into a single strand and winding the single strand on a spool.  A very high pressure is applied to the nip of the first and third pair of rolls in addition to that provided by the weight of the upper roll of the pair.  All of the steps are carried out at 20-35 DEG C. and the total draw ratio employed is 3.0 to 4.0.  It is stated that there is no significant advantage of applying pressure to the nip of the second pair of rolls in addition to that provided by the weight of the upper roll.  The stretched strands are condensed into a single stretched strand, the denier of which may, for example, be about 1,200,000, and the single strand is then wound on a spool.  The filaments may consist of nylon-66.

[Also in Division H1] A water-heating appliance, such as an electric kettle, for example, has a control switch which can be selectively set to cut-off the supply when the water boils or to cycle and keep the water close to boiling temperature. Steam from a kettle 1 passes through a hole 11 into an insulating housing 7 where it causes a bimetal strip 8 to urge a plunger 12 against a spring strip 13 to which is attached one end of a snap-action spring 15, the other end of this spring being secured to a blade 16 carrying a moving contact 18 and pivoted in a groove 20. When strip 13 is moved sufficiently for spring 15 to pass the axis 20, blade 16 snaps overcentre to open contacts 18, 17. A manual control member 22 can be selectively set such that an abutment 23 thereon limits the movement of blade 16, as shown, so that on cooling of bi-metal 8 the spring 15 returns overcentre and recloses the contacts 18, 17. If member 22 is set to its position, allowing blade 16 to move further away from fixed contact 17 (as in Fig. 3, not shown), the spring 15 does not return past axis 20 on cooling of the bi-metal and the contacts 17, 18 remain open until reset by depression of member 22 to the position shown in Fig. 1. Alternatively, a separate reset member may be provided in the form of a tell-tale which indicates when resetting is necessary.
