Abstract: 446,945. Collapsable tubes. SANDER'S CHEMICAL PRODUCTS, Ltd., 43, Regent Street, Loughborough, Leicestershire.-(Sander, E. ; 2, Schackstrasse, Munich, Germany) Aug. 21, 1935, No. 23486. [Class 66] [See also Group V] The extrusion orifice of a collapsable container formed from a polymerizate of vinyl alcohol or acrylic acid consists of a slit 4, Figs. 1, 3, formed in the neck portion 3, which is of elastic nature, and adapted. to be opened by the pressure of the contents when the container is squeezed. The neck is encircled by a rigid metal collar 5 of elongated form provided with finger pieces 6, and by turning this through a quarter turn from the position shown the neck is distorted and the orifice prevented from opening to discharge the contents. A flexible metal strip 2 is inserted in the opposite end of the container before , closing, to assist in preserving the shape when rolled by a key. The containers may be made as shown in Fig. 4, by depositing from solution layers of the substance upon a glass or aluminium core 8 in such a manner as to produce a thickened, closed end, a suitable solution consisting of one part by weight of polymerized acrylic acid acetic ester and four parts of acetic acid ethyl ester ; the layers are deposited alternately from the solution given and from a similar one containing from 1 to 5 per cent of a softener such as di-isobutyl phthalate. The closed end is cut off along the line C-D and a block 12 of the substance rendered elastic by the softener is cemented by means of the solution in the opening, the slit being formed in the block either before or after attachment to the container. Specification 417,793 is referred to.

Abstract: 1433929 Lowering apparatus M TSUDA 18 May 1973 [22 May 1972 23 Dec 1972 (2) 18 Jan 1973 8 Feb 1973] 23757/73 Heading B8B [Also in Division F2] A slow descending mechanism for lowering a person on a rope 3 comprises a rope pulley 1 whose rotational speed is restricted by a centrifugal brake 7 drivingly coupled to the pulley 1 through planetary gearing 12, 14, 15 whereby centrifugal weights 20 of the brake rotate faster than the pulley 1. The weights 20 carried by a rotor 16, are engageable with non-rotatable V- sectional linings 21. On the opposite side of the pulley 1 to the centrifugal brake, an oil-hydraulic brake 9 in the form of a vane pump or inscribed gear pump is provided, connectable to the pulley 1 through a centrifugal clutch 8 so that the hydraulic brake 9 supplements the centrifugal brake 7 above a certain rotational speed of pulley 1. The clutch 8 includes pawls 28, 29, pivotally mounted on a plate 30 rotatably fixed to the rotor of the hydraulic brake 9, and a driving plate 23 rotatably fixed to the drum 1 and having radial projections 24 for knocking and rotating the pawls 28, 29 against spring bias towards hooked discs 25, 26 secured to the plate 23. With sufficient rotational speed of the plate 23, the pawls are knocked into locking engagement with the discs 25, 26 to engage the clutch, until the pawls are spring returned with reduction in pulling speed. The rope 3 is guided to and from the pulley 1 by rollers 60, 62 mounted in a swinging frame 63, 64 and the rope may be locked on the pulley 1 by spring biased rollers or a peripheral guide plate. The rope 3 is locked until the person attached thereto by a safety belt is ready, by a hand operated camming lever Fig. 14 (not shown) controlling a wave shaped rope clamp. In the embodiment of Fig. 17 (not shown) the pulley gearing is lockable by a hand operated plunger engageable with a slotted drum keyed to the gearing, the spring biased plunger being controlled by a cam profile or a ratchet wheel incrementally rotatable by a pawl on a hoist lever. In the embodiment of Fig. 19 (not shown) a safety bolt clamp facilitates attaching the belt to a said point of the rope, wherein the rope is laterally received in an opening and two wedge effect clamps are rotated to grip the rope. In the embodiment of Fig. 20 (not shown) the safety strap is coupled to the rope end through a bearing permitting the rope to whirl relative to the belt.
