Title: Vehicle for delivering goods in measured quantities at different points of use
IPC: G01G19/00
Filed: 1948-06-14
Abstract: 646,109. Vehicle fittings. MERWEDE, W. J. S. VAN DER, and MERWEDE, J. F. S. VAN DER. June 14, 1948, No. 16007. Convention date, June 27, 1947. [Class 78 (iv)] [Also in Group XVIII] A vehicle for delivering goods in measured quantities by weight or by volume comprises a hopper for containing the goods in bulk and a discharge device having a measuring apparatus and a suspension means for a container intended to receive the measured quantity of the goods and a transporting device for the container for bringing the container to the required position for handling. The hopper 1 has a discharge shoot 4, a sieve 2 over a container 3 and a sliding closure 4<1> for the shoot. The outlet of the shoot can be closed by a counterweighted slide 5. A shoot 8 extends from the shoot 4 and guides the material into a sack 13. The weighing apparatus is suspended by a bracket 27 at the rear of the vehicle and comprises two horizontal weighing arms, one for the tare and the other for the load. The balance is supported in a framework 9 which is adjustably mounted in a horizontal shaft mounted anti-frictionally in bearings secured to the bracket. A spirit level 10 may be incorporated. The sack is supported by a hanger and hooked on to the weighing arm. The sack may be raised or lowered by a winch 36, and pulleys 24, 25, and cable 23, 40.

Abstract: 272,939. Naamlooze Vennootschap Nederlandsche Kunstzijdefabriek. June 16, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Cellulose xanthates, processes for making filaments from.-Artificial textile threads less glossy than artificial silk, and having a dull appearance, are obtained by employing a viscose containing sulphides, sulphites, thiosulphates or other substances which, during spinning, give rise to the deposition of sulphur. The threads are washed, bleached and dried, but they must not be subjected to the usual desulphurizing process. Threads so obtained may be used for the manufacture of hosiery and other knitted goods, fabrics &c., and for such purposes they may be used alone or mixed with other materials such as artificial silk, in which case goods showing contrasting lustre or colour effects are obtained. In an example, one per cent of sodium sulphite is added to the viscose, and the solution is spun into a bath as described in Specification 2485/15.

Title: Improvements in master-cylinders for hydraulic pressure systems
Inventor: BUTLER HENRY JAMES
IPC: B60T11/224
Filed: 1950-07-01
Abstract: 698,417. Mastercylinders. DUNLOP RUBBER CO., Ltd. June 13, 1951 [July 1, 1950], No. 16479/50. Class 103 (i). A mastercylinder for pressurizing brake and other hydraulic systems comprises, as shown in Fig. 1, a pedal-operated main piston 8 slidable in a cylinder 1 and having a plunger 13, 14, 15 projecting them from and slidable in a smaller cylinder 2. The cylinder 1 is supplied with liquid from a reservoir through a check valve 23 fitted adjacent a relief valve 22 which lifts to prevent excessive pressure being created in the cylinder 1. In the retracted position of piston 8 shown, the inside of cylinder 1 is in communication through passages 16 and 17 in the plunger part 15 with the interior of cylinder 2 so that as the piston 8 is advanced liquid is forced direct from the cylinder 1 through cylinder 2 and by connection 5 to the brake cylinders or other hydraulic device. When the plunger part 13 enters the cylinder 2 communication between the two cylinders is interrupted and thereafter the plunger transmits pressure at a higher ratio to the actuated device by reason of the smaller effective piston area. In a modified arrangement, the piston has a bore therein within which slides the plunger which is anchored to the opposite end of the cylinder. The bore in the piston is closed and forces liquid through a central passage in the plunger and out through an end connection to the brakes. In a further modification of such an arrangement, as shown in Fig. 3, the internal bore of the main cylinder 45 is stepped, and movement of the main piston causes liquid to be pumped through a connection 51 at the large part of the bore as well as the end connection 48, the two outlets being hydraulically separated when the piston enters the small part of the cylinder bore.

Another embodiment comprises 3 panels each with electrodes of one colour and electrode 5 continuous. Light guides extend from the panels to a display screen where they are arranged in triplets. The elements may be arranged in a figure-of-eight.

A man-hole cover assembly comprises a lid or cover 2 hinged to one side of a frame 1 and a spring-loaded extensible stay A pivotally connected between the frame and the cover and arranged so that when the cover has been raised a certain distance the stay will become operative to counterbalance and then overcome the weight of the cover and thereby to retain it in the fully open position. The stay comprises two telescopic tubes 11, 12 containing a spring 13 and pivotally connected between a bracket 29 on the frame and an arm 16 depending from the cover, the pivot 15 being located, when the cover is closed, either on or below the line joining the pivot 14 with the hinge axis of the lid. A second similar stay B may be pivotally connected between a short arm 23 on the cover and an oblique depending arm 21 on the frame so as to act on the cover with a different leverage from that of the stay A. This is stated to ensure a more even opening and closing effort and to avoid snap closing. A safety catch 25 pivoted to the coyer engages beneath a stop lug 27 (not shown) on the frame to restrict the initial opening of the cover.

[Class 143] Relieving and locking mechanism.-In a weighing scale wherein the pans are carried at opposite ends of a beam 10, a cranked arm 22 and stop 26 rotated by a handle 25 are situated beneath one pan support 12 so that the stop 26, in the position shown, limits the pan's downward movement, and on rotation of the handle to relieve the beam an antifriction roller 23 lifts the pan support 12 to its locked position. During the upward movement of the -pan support 12, the pan support at the other end of the beam descends on to. a pair of fixed buffers, the pan support 12 is raised off its knife-edges 14, and cover plates 16 engage the backs of the knifeedges and lift the beam so that its fulcrum knifeedges 14<1> are raised trom their seatings. Further upward movement of the beam brings the backs of the knife-edges 14<1> into engagement with their cover plates 16<1>' and tilts the beam until the knife-edges at the other end of the beam leave their seatings thus relieving all the knife-edges and locking the scale parts against movement. The roller 23 may pass beyond its. highest point until the cranked part 22a of the arm 22 engages the pan support so that the crank is self-locked.

Abstract: 704,456. Apparatus for making pile fabrics. DUNLOP RUBBER CO., Ltd. June 6, 1951 [July 6, 1950], No. 16867/50. Class 140 In an apparatus for the electrostatic production of pilefabrics which includes means for delivering fibrous material to the space between a pair of vertically spaced electrodes while adhesive coated backing material is passed in contact with the upper electrode, means are provided, movable independently of the electrodes, for vibrating the backing material as it passes through the space between the electrodes. Backing material 28 from roll 5 is fed through driven nip rolls. 6 to spreading knife 9 where the coating of adhesive applied from container 7 is levelled to 0.006- 0.012 in. thick. The adhesive coated fabric is then passed in contact with upper electrode 1 which has a solid or hollow hexagonal bar 3 mounted in a slot and motor driven to give a vibration frequency of 5,000-15,000 cycles/min. The pile fibres are extracted from hopper 24 by oppositely rotating brushes 25, 26 and showered on to endless belt 19 which carries them between electrodes 1, 2 where they become attached to the adhesive coated backing due to the effect of the electric field between the electrodes, e.g. a drop of 12,000 volts/cm. Excess fibres are collected at 27. After application of the fibres the backing 28 is passed through hot air chamber 11, to set the adhesive, and driven nip rolls 16 to ensure the backing is under tension to stock roll 17. The brush 26 may rotate at four times the speed of brush 25. Other forms of rod 3 may be used, e.g. star shaped, circular eccentrically mounted, or circular with paddles, and several rods may be used at the same time.
