Abstract: 822,184. Knitted fabrics. BUNGER, A. April 23, 1956 [Oct. 4, 1955; Feb. 21, 1956], No. 12420/56. Classes 74 (1) and 74 (2). Artificial Persian lamb comprises a warpknitted or crocheted ground fabric, the threads of which bind in curly cords a, such as chenilles or wicks of curled fibres, which cords extend side by side on the ground fabric, each over a part of the width of the fabric and generally in the direction of the wales, in lines which meander irregularly and in different ways as between adjacent cords. In Fig. 2, the ground fabric is of separate warp chains b held together by wefts h. In the ground fabric of Fig 4, the warp chains are interconnected; as in the right-hand wale, additional warp threads may be provided, each confined to the one wale, and inelastic or elastic warps m may be tied in. The cords may comprise groups, each containing cords 1-4; one cord of each group is supplied by a common feed-bar and, by giving the bars different movements, the individual cords within a group are made to follow different courses. Between the points at which they are tied in, the cords float, as at i, i<SP>1</SP>, k. The chenilles consist of longitudinally extending threads of cotton holding between their transverse threads of artificial silk, animal fibres such as wool or synthetic material such as a polyamide. The ground fabric threads may be of cotton, a super-polyamide or other synthetic material. A backing of, say, flexible synthetic material may be glued to the ground fabric.

Filed: 1944-06-30
Abstract: 584,450. Variable - pitch propellers. FORSYTH, A. G., and FAIREY AVIATION CO., Ltd. June 30, 1944, No. 12491. Convention date, Aug. 12, 1943. [Class 114] A control device for an electrically-operated, variable-pitch propeller, controlling two operating electric motors, is mounted centrally at the top of the operating gear housing. Two electric motors 10, 12 drive the worm-wheel 28 which is splined to the shaft 30. This shaft', through gearing 32, 34, arm 36 and sleeve 38 turns the gear ring 40 which operates the pitchchanging gear mounted on the propeller hubs, as described in Specification 580,488. Teeth on the sleeve 38 and teeth 50 on the ring 52 driven by the engine engage wheels 54 and 56 respectively. Relative movement between these wheels, caused by operation of the pitchchanging motors moves the nut 66 along the screw 64, this nut operating limit switches 68, 70, 76 and 78. With the hand control switch 86 in the position shown (Fig. 4), the motors 10, 12 operate to bring the propellers to coarse or fine pitch according to which of the switches 82 or 80 is closed by the engine-driven governor 84, movement in each direction being stopped by the limit switches 76, 70. Power from the motor is supplied by one of the batteries 92, 94. For feathering, the switch 86 is moved to contact 88 and both batteries are placed in series to give a quicker motor movement. Reversing is similarly effected. Switch 110 ensures that reversing current takes place until the engine speed has fallen below a predetermined r.p.m.

Filed: 1961-04-13
Abstract: 974,806. Packaging; endless conveyers. F. MONHEIM, H. MONHEIM, P. LUDWIG, H. G. MONHEIM, and D. MONHEIM, [trading as LEONARD MONHEIM K.G.]. April 13, 1961 [April 14, 1960], No. 13387/61. Headings B8A and B8C. In a method of packing articles e.g. chocolate creams P, in containers the separate articles are held by retaining means in a plurality of longitudinal rows arranged side by side so as to form a series of transverse rows of articles and released a transverse row at a time, whereby those articles in the same transverse row are transferred to the container, one or more articles being omitted from each transverse if it is required to arrange the articles in a desired pattern in the container. In one embodiment (see Figs. 1 and 2) the chocolates P are supported in longitudinal rows in inverted U-section magazines 10-15 moved step-by-step over a conveyer 40 which carries the boxes 41 transversely beneath the magazines. Each magazine contains a different kind of chocolate. The magazines have holes 30 above each chocolate, and at station A a bar 23 with downwardly projecting rams 21 is depressed against springs 24 to eject a transverse row of chocolates into a container, which then passes to station B where a bar 23 offset from the bar in station A is depressed to eject a transverse row from the next set of magazines. At station C a third transverse row is ejected. The rams may be simultaneously operated. The chocolates may be retained in the magazines by a sponge rubber lining or by springs or retaining ribs. Patterns of chocolates may be formed in the boxes by locking certain of the rams 22 in their uppermost position so that they do not eject a chocolate. Fig. 3 shows a magazine in the form of a belt with projections 31 which pick up the chocolates from a feed conveyer 33. The magazine may be supplied with chocolates only at particular places, the gaps in the boxes being filled at subsequent stations. The conveyer belts may be vertically arranged in pairs, as in Fig. 5, the chocolates being held between the belts by cushioned projections 32 and dropped directly into the container 41 at the bottom of the path of the conveyers. These pairs of conveyers may be arranged diagonally across the conveyer 40 (see Fig. 6, not shown).

Patent GB-134543-A (GB)
IPC: B60L15/34
Abstract: 134,543. Westinghouse Electric & Manufacturing Co., (Assignees of Hall, A. J.). Oct. 30, 1918, [Convention date]. A u t o m a t i c circuitbreakers; pneumatic actuation.-In a circuit-breaker which is operated to the closed position by pneumatic pressure, the pressure is admitted by manually-controlled electro-magnetic means, and means are provided for preventing such closure until a pre-determined degree of fluid pressure is available. In the arrangement shown for closing the switch 5 which may be the main supply switch on an electric locomotive, the pressure from the main pressure pipe 36, or from the auxiliary manually supplied reservoir 37 (if owing to the train being out of action for some time the main source is not available) is admitted through the three-way valve 35 through a supply valve 7 electro-magnetically controlled by a circuit containing the push-button 75 and through a quick-acting valve 8 to the underside of the piston 30 which is thereby moved upwardly against the action of the spring 32 to close the switch. The valve 8, Fig. 2, has an inlet port 61 admitting pressure to the underside of the piston 66; if the supply pressure is inadequate for the complete operation of the switch, the piston is only partly raised and the pressure escapes round the upper end of the piston and through the channel 73 to the atmosphere, without passing through the port 71 to the switch-actuating piston. With adequate pressure, however, the piston is fully raised and the outlet to the atmosphere is closed so that the pressure passes to the switch piston. The switch is held in the closed position against the returning action of the spring 32, when the pressure has been removed, by a detent armature 22 held by an electro-magnet 21 energized from a local battery circuit containing an overload time-limit relay 3 which opens the detent circuit and trips the main switch when the current from the trolly is excessive. The relay comprises a solenoid plunger 12 which is lifted to permit mercury to flow slowly from the outer chambers to the central chamber 13 of a mercury container and expose a contact 14.
