Title: Improvements in automatic windscreen wipers
IPC: B60S1/08
Filed: 1938-11-07
Abstract: 510,066. Windscreen-cleaners. ZEISS IKON AKT.-GES. Nov. 7, 1938, Nos. 32283 and 32284. Convention dates, Nov. 10, 1937, and Dec. 15, 1937. [Class 138 (i)] A windscreen-cleaner mechanism comprises means operable at will for lengthening the driving crank so as to increase the amplitude of oscillation of the wiper for parking purposes, and means operated automatically, as a consequence of such lengthening, for lifting the wiper off the surface of the screen before it is moved to parked position Means also may be provided for switching off the wiper motor when the wiper reaches its parked position. The wiper arm 1 is pivoted at 6 to a rock-shaft 2 which is axially slidable in a bearing 4 and carries a pinion 3 driven by a rack 5. When the crank which drives the rack is lengthened, a projection 8<1> on the pinion engages a fixed cam surface 8, so that the shaft 2 is moved axially. A fixed pin 9 then tilts the wiper arm clear of the screen. The crank 15 is slidably mounted on an eccentric sleeve 13 fixed by a pin 14 to a shaft 12 rotated by a motor 11. The disc 19 of the crank has a diametral groove 17 which is pressed into driving engagement with the pin 14 by a spring 16. When the wiper 29 is at rest and parked, the crank has an effective length R, Fig. 10. If, now, a button 21 is pushed, it first closes the motor contact 22, and then slides the crank out of engagement with the pin 14. Upon release of the button, the sleeve 13 having made one half revolution, the groove re-engages the pin 14, giving the crank an effective length r, Fig. 11. The crank now oscillates the wipers through their normal operative stroke by means of the link 23, racks 24, 24<1>, and pinions 28. Reciprocation of the rack oscillates contacts in a switch 33 in such a manner as to keep the motor circuit closed, although the contact 22 is now open. To stop and park the wipers, the button 21 is again pushed and released. This causes the groove to re-engage the pin 14 with the crank lengthened, so that the wipers are moved beyond the limits of their normal stroke, and lifted clear of the screen by the pins 9. At the same time, the motor circuit is broken at the switch 33. The racks 24, 24<1> are adjustable in a connecting member 27, for various sizes of vehicles. In a modification, the wiper shaft 2 is fixed, and the pin 9 is movable by means of a bell-crank lever and an abutment on the rack. The Specification as open to inspection under Sect. 91 states that the wiper may first be lifted from the screen, this operation automatically effecting the turning of the wiper. This subjectmatter does not appear in the Specification as accepted.

Abstract: 863,017. Valves. SOLTESZ, P., and TAMNENBAUM-, N. Oct. 17. 1957 [No. 21, 1956], No. 32404 /57. Class 135. [Also in Group XVII] A flow control valve for an infant's feeding- bottle comprises a member 22 fitted between a teat 6 and a connection 5 of a receptable 3 secured to the bottle neck, the member 22 having in its end an opening 23 shaped as a segment of a circle. An oblique slot 27 in the member 22 and a co-operating cam 28 on the connection 5 enable the member 22 to be moved axially thereon, the movement being effected by turning an apertured disc 7 which forms a tight fit on the teat so that the members 7, 6 and 22 rotate together to open or close the opening 23. In a modification, Fig. 7, the connection 5 has a recessed portion 29 so that, without axial displacement, the member 22<SP>1</SP> may be rotated to align or disalign the portion 29 with the segmental opening in the member 22<SP>1</SP>.

Abstract: 470,893. Feeding webs. RINCO AKT.- GES. Nov. 26, 1936, No. 32413. Convention date, Nov. 29, 1935. [Class 100 (i)] In a web-turning bar having longitudinally reciprocating web-engaging bars actuated by a helical cam surrounding the turning bar, the cam is in the form of a closed guide track having a diameter greater than that of the surfaces of the web-engaging bars. The web-engaging bars 12, Figs. 1 and 2, are made of thin hard steel and are secured at one end to members 8 mounted in radial grooves 7 in a cylindrical block 6 secured to a stub shaft 1 driven by a gear 5. The members 8 are provided with rollers 10 engaging a cam guide track 9<1> formed by the space between the helical ends of a pair of sleeves 9 secured within a fixed casing 3. The diameter of the track 9<1> is about twice that of the surface of the bars 12. The bars 12 are supported by guide rails 13 secured to a sleeve 1<1> mounted on the stub shaft 1, and provided with channels 14 through which cold compressed air is passed to remove any heat generated by the friction of the bars 12 on the rails 13. This friction may be reduced by allowing slight radial play of the bars on the rails.

Abstract: 1418491 Moulding BAKER PERKINS HOLDINGS Ltd 25 June 1973 [14 July 1972] 33003/72 Heading B3F [Also in Division B1] Means for preparing foundry sand for moulds or cores comprises means 12 for supplying successive batches of sand/binder mix and sand/ catalyst mix to a mixing chamber 14 having an outlet 14c for discharging the successive batches into a single core or mould box, means for purging the chamber with compressed gas between mixing operations and means 16 for controlling the number of batches and volume of each batch supplied to the mixing chamber. The units 12 are as described in Specification 1,051,651 having feed screw sections 12a, mixer blades 12b and paddles 12c. The units are supplied with foundry sand at a controlled rate by means 10 as described in Specification 1,286,162 having barrels each with a side opening surrounded by a sleeve rotatable to vary the size of the opening formed at the base of a sand hopper. The mixer 14 is as described in Specification 1,369,446 having a rotating mixing device with spring steel blades 14a which sweep the roof and walls of the chamber and blades 14b sweeping the base. The outlet 14c is in line with, or offset from, the roof inlet and is controlled by a sliding door 14d. Inlets 14e admit purging air from a ring main. The cold-setting mixture drops from the outlet into the mould or core box on a vibrating table, which may be pivoted to an inoperative position. The desired number of batches is set on a dial 16a and the weight by a dial 16b which allows a set number of revolutions of the screw (counted by a magnet-carrying disc), thus determining a weight. Thus 3 batches each of 50 lbs may be selected. In operation, a push-button causes the mixer door to be closed and the feed shafts of the units 12 rotate. When a set quantity has been fed, an electronic timer determines the opening of the discharge door of the mixer. The quantity dial is then automatically reset and the batch dial advanced. Timing means then control the purging of the mixer, the closing of the mixer and the sequential supply of further batches.

Title: Improvements in or relating to the production of artificial filaments
IPC: D01D5/04
Filed: 1932-11-23
Abstract: <PICT:0410795/IV/1> <PICT:0410795/IV/2> Apparatus for attemperating the spinning solution in the production of artificial filaments by dry spinning methods comprises a body such as a coil 12 through which the spinning solution passes and which is adapted to be exposed to the atmosphere in the spinning cell 3, and a shield 8 which is adjustable with respect to the body so as to regulate the extent to which the body is exposed to the atmosphere of the cell.  The cell which is heated by pipes 4 has a filter candle 5 with an adapter 6 carrying the nozzle 7.  The solution passes through the candle 5 to the adapter 6, up a pipe 11 and through the coil 12 to the jet 7, loss of heat from the heated solution being minimised by an asbestos washer 13.  The coil 12 and candle 5 are adjustably sheathed by a split jacket 8 fixed to the required position by tightening the band 9 by the screw 10.  The apparatus is applicable for use with solutions of cellulose esters, ethers or ether-esters.  Two or more candles in the same cell may have their shields differently adjusted so that the solution issues from the different jets at different temperatures, the resulting filaments therefore having different lustres.  The coil 12 preferably has a high heat conductivity and its surface may be corrugated, while the shield is of low conductivity and may be of asbestos.
