Title: Improvements in heating devices for the precombustion chambers of diesel engines
IPC: F02B19/14
Filed: 1933-10-26
Abstract: 426,013. Oil engines. DAIMLERBENZ AKT.-GES., Untert³rkheim, Stuttgart, Germany. Oct. 26, 1933, No. 29752. Convention date, Oct. 26, 1932. [Class 7 (iii)] A portion of the wall of a precombustion chamber of a Diesel engine which is not impinged upon by the fuel is heated by means surrounding the chamber, or is formed as an insert and heated either by the heat produced in the precombustion chamber or electrically. As shown in Fig. 1, the walls of the chamber a<1>, a<2 >are formed by insertions e<1>, e<2>, e3 which are partly cooled by the water jacket f in the cylinder head g, and the part el is surrounded by an incandescent spiral il. The wall of the chamber a<1> which is subject to less stress may be made of copper, whilst the highly stressed chamber a<2> is made of steel. In modifications, (1) the heating- member is provided on the inside of the insertion e<1> and consists of a metal spiral inserted in insulating-material; (2) the walls of the chamber are formed by two insertions and a heating-member, made of copper or other material of high thermal conductivity, which may not be heated electrically; and (3) the heating-member surrounds the chamber and is arranged between shoulders on the cylinder head and the insertion piece. The heating-member is used only during starting, idling, or running at low speeds, and may be insulated by mica or asbestos from the cooled outer wall. The Specification as open to inspection under Sect. 91 also states that the heating-member may be formed by pins projecting into the combustion chamber. In the construction shown in Fig. 5 (Cancelled), the current to the heating-member i, which forms part of the wall of the precombustion chamber and may be made of beryllium bronze, is controlled by a switch m or variable resistance which is operated by the accelerator pedal p or speed regulator, so that the heating occurs during starting, idling, or running at low speeds. A switch l operated by hand from the dashboard enables the current to be cut off when desired, and by closing the switch l and a switch n the current may be switched on permanently when desired. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to footwear
IPC: A43B9/10
Filed: 1959-09-01
Abstract: 905,540. Making footwear. KEFERSTEIN, C.G. Sept. 1, 1959 [Sept. 2, 1958], No. 29791/59. Class 17 (2). A method of making footwear comprises sliplasting an upper and insole which are secured together, a margin of the upper extending below the insole, and bonding the inner face of this margin to the outer edge of an outsole. Where the upper 5 has a lining 1, as in Fig. 4, the insole 3 is secured to this lining, e.g. by the line of stitching 2. The lasted assembly is placed over the outsole 6 with the extension of the upper 5 against the outer edge of the outsole 6, a lower pair of wipers 7 is moved inwardly to clamp the extension against the outsole, and then an upper pair of wipers 8 is moved inwardly to stretch and wipe the upper over the top face of the outsole and to conform it to the contour of the lower face of the last. In this position of the parts (Fig. 6), the outer face of the insole 3 which contacts the top face of the outsole 6 and the confronting faces of the outsole 6 and upper 5 are bonded together. This bonding may be effected by the use of a suitable cement between the parts or, in the case where an initially unvulcanized rubber outsole is used, by vulcanization. In the modification shown in Fig. 10, the extension of the upper 5 is shown as provided by a strip 10 secured to the upper, lining and insole as by a line of stitching 11. An inner clamping-plate 16 with two lateral clamping plates 17 may underlie the outsole 6 (Fig. 13), the purpose being to hold the marginal extension of the upper sufficiently tightly to the outsole to enable the stretch to be taken fully out of the upper when wiping under the last bottom. In a modified apparatus, the plate 16 forms an outsole mould and additional inner and lateral clamping-plates are provided beneath the plates 16, 17.

Abstract: 192,784. Passat, J. B. Nov. 9,1921. Screw propellers for aircraft with variable-pitch blades have controlling means whereby the blades are free during part of each revolution and are constrained to a graduated pitch during the remainder of the revolution. The blades 7 have stems 3 which are freely held in sockets 4 on a disc 5 attached by spokes 6 to the boss 1 and the stems are also stepped into sockets 2 on the boss 1. The leading edge of each blade is nearer the stem than the trailing edge, so that the blades tend to swing into the radial plane. Each stem 3 'has two tappet members 8, 9 with rollers 13 which are adapted to contact with a cam 11 during part of revolution to give the blades a definite pitch. Pitch control is effected by sliding the block 14 carrying the cam by means of a central rod 19 attached to the yoke 18. Further control, whereby the blades are retained in a definite pitch position during a complete revolution, is obtained by movement of a four armed member 20 which is connected by slotted rods 22 with radial projections 21 on the blade stems.

Abstract: 884,115. Centrifugal pumps. KLEIN, SCHANZLIN & BECKER A.G. Sept. 2, 1960, No. 30392/60. Class 110 (1). In the multi-stage centrifugal pump shown, end thrust is balanced by a disc 8 mounted on the pump shaft within a chamber 1 supplied via a conduit 3 with pressure liquid from an intermediate stage of the pump. Axial displacement of the shaft due to a change of impeller thrust varies the gap between the disc 8 and a stationary partition to provide a variable leakage from the chamber 1 whereby the pressure in the chamber 1 varies in the sense to restore thrust equilibrium, in the known manner. According to the invention, the conduit 6 which returns the leakage from the chamber 1 to the pump inlet (or to a reservoir upstream of the inlet) includes a flow-sensing device 7 which adjusts a throttle 4 in the conduit 3, whereby the pressure in the chamber 1 is varied in the sense to assist in restoring thrust equilibrium. If the pumped liquid is hot, a cooler 5 may be provided either in the conduit 3 as shown or in the return conduit.
