Title: Fluid mixing device
IPC: A47L15/44
Filed: 1963-11-15
Abstract: 1,064,497. Fluid mixing-apparatus. DEMA ENGINEERING CO. Nov. 15, 1963 [Jan. 10, 1963], No. 45224/63. Heading B1C. In apparatus for mixing liquid detergent with water, a chamber open to atmosphere is provided between a mixing valve body and a cap for connection to a pipe or faucet supplying water under pressure so as to prevent backsyphonage of detergent into the water supply line should a partial vacuum occur therein. As shown water flows through aperture 15 into a channel 30, any excess flowing down channels (35) (Fig. 2 not shown) between nozzle 27 and valve body 16. By pressing a button 42 air passage 40 is closed and detergent is induced, by the pressure differential thus caused, into the channel 30 in a proportion controlled by metering screw 50. Detergent flow is stopped by cutting off the water flow so as to equalise pressures at the restriction 32 and passage 40 whereupon button 42 is urged outwardly by spring 44. In either case reverse flow in the water line merely causes air to be drawn through passages (23) (Fig. 2 not shown) between cap 10 and body 16 into the chamber 21 and through aperture 15, flow through the channels 30, (35) ceasing automatically: In a modification (Fig. 4 not shown) the air passage 40 is omitted and the valve body 16 is closed at the bottom, the liquid flowing out through the side of the valve body into a pipe (80).

Title: Wheel brake having two brake shoes
IPC: B60T7/20
Filed: 1973-09-28
Abstract: 1438579 Internal shoe drum brakes V KNOTT [trading as MASCHINENBAU KNOTT EGGSTATT Ing VALENTIN KNOTT] 28 Sept 1973 [30 Sept 1972] 45489/73 Heading F2E In a wheel brake comprising a brake drum (not shown) rotatable relatively to a brake shoe carrier 4, Fig. 1, and two brake shoes 1, 2, each of which bears at one end against the brake shoe carrier and co-operates at the other end with a floating expander 5, the brake lining 7 of at least one of the shoes (shoe 1, as shown) being mounted on a lining carrier 6 which can move relatively to the brake shoe 1 the relative movement between the lining carrier 6 and shoe 1 is guided, and spring 9 (one not shown) are provided for biasing the lining carrier 6 towards a first position of operation relative to the associated brake shoe 1. As shown, the brake shoes 1, 2, bear at their lower ends against a slack adjuster 3 associated with the shoe carrier 4 and co-operate at their upper ends with the floating expander 5. The lining carrier 6 is movably associated with shoe 1 by cam surfaces 13, 14, on carrier 6 engaging pins 10, 11, respectively on shoe 1. The respective cams and pins are retained in contact by the pre-stressed tension springs 9 (one only shown) extending on both sides of shoe 1 and carrier 6 between bores 15, 16, in carrier and shoe respectively. Cam surface 13, Fig. 3, begins with a partcircular recess 13A of radius substantially equal to that of pin 10, continues with a further recess 13B of at least twice that radius and ends with a straight line 13C perpendicular to the direction 8, Fig. 2, of the expanding force. Cam surface 14, Fig. 2, begins with a straight line which, produced, makes an angle of 36 degrees with the direction 8 of the expanding force, continues with a part-circular recess 14A of radius substantially equal to that of pin 11 and to which the first line is tangential, and ends with a further tangent to the recess, at right angles to the first straight line. In operation, with travel in the forward direction 12, Fig. 1, springs 9 maintain carrier 6 in the position of Fig. 1, and the brake when applied, behaves as a two-shoe non-servo brake. When the direction of rotation is reversed and the brake is applied, lining 7, being entrained by the drum, not shown, causes movement of the carrier 6 relative to the shoe 1 against springs 9 in an approximately clockwise direction until pins 10, 11, occupy the positions, relative to carrier 6, shown dotted in Fig. 2. Thus the brake is less forcefully engaged, and, if mounted on a trailer, permits reversing of the trailer. On resumption of forward movement, springs 9 restore carrier 6 to the Fig. 1 position without delay and without the necessity for relieving the action of expander 5, so forward braking power is immediately available. During reverse movement, the brake may be more forcefully engaged, despite the movement of carrier 6 by the drum, by further application of expander 5.

Abstract: 1469256 Yarn splicing apparatus FIBER INDUSTRIES INC 21 Oct 1974 [31 Oct 1973] 45512/74 Headings D1F and D1W An apparatus and method for joining yarn ends has two clamp members to hold the yarn ends in abutting parallel alignment, means to draw by a predetermined draw ratio and then relax the yarn, a fluid jet entangling assembly and an actuator assembly to operate these parts in sequence. The hand held apparatus shown in Fig. 1 has a pair of clamping heads 14, 16, Fig. 2, which are forced apart by air pressure to hold the yarn. The draw relax assembly, Fig. 5, comprises two arms 84, 86 which are swung outward from the apparatus to draw the yarns and then continue to swing inwards to relax and at the same time deposit the yarns in a channel 48, Fig. 1, where a cover 64 descends to trap the yarns and air jets 56, 58 perform the entangling. The apparatus is operated by a trigger 110 which actuates valves 118, 120, 122 to operate the various air operated parts and by a pull cord 104 rotates shafts 80, (82) (not shown) which support the arms 84, 86 and hence effect the draw, relax operation. The time during which the fluid entangling assembly operates is determined by a spring loaded piston 162 in a controlled leakage air cylinder 166 which, via a mechanical linkage closes the appropriate air valve. In an alternative embodiment, Figs. 8 and 12, the yarns are held between a fixed clamp 214 and a movable clamp 216 this movement giving the draw, relax operation. The fluid eneangling assembly is formed in the join of a fixed part 240 and an advancable part 242. The moving parts are operated by air pressure, as is the entangling assembly and the whole operation is controlled by a bank of cams 304, 306, 308, 310, 312, Fig. 12.

An extension connected to a P.M.B.X. can seize an available exchange line by operating a push-button switch which causes the line to be seized and this action indicated to the operator. If the available exchange lines are busy, the normal call light signal is presented to the operator. In operation when the extension goes off-hook and the push-button is operated, relay E pulls up, locks over E3, E4, seizes an exchange line and gives a busy lamp signal to the operator. When the call is concluded, a relay CT (not shown) operates to release relay E. The exchange line is available to a plurality of extensions as well as to the operator so provision is made, by choice of resistor R1, to prevent a second relay gaining access to the same line, so when the operator is using the line contacts N are bridged so that relay E will not pull up. The relay may be replaced by transistor switches.
