Title: Fitments for containers from which liquid is intended to be withdrawn by a hollow needle or tube
IPC: A61L2/18
Filed: 1981-12-09
Abstract: A container 2 provided with a self-sealing closure member 4, through which a needle may be inserted to withdraw liquid 3 from the container 2, is fitted with a sterilizing cap 1. The space within the upper region of the cap 1 is divided into compartments 20, 21, each containing a sterilizing substance. A needle can be caused to penetrate a weakened region of the cap 1 and to pass through one of the compartments prior to penetrating the closure member 4 and being introduced into the liquid 3 within the container 2. After the needle has been passed through one of the compartments a number of times, it may be passed through another of the compartments which contains fresh sterilizing substance. <IMAGE>

Title: A master cylinder assembly for a vehicle braking system
IPC: B60T11/10
Filed: 1982-04-27
Abstract: Each piston (3) of a twin master cylinder assembly "A" is guided to slide in its respective bore (1) only by the sliding engagement with the bore (1) of a guide portion (9) of the piston (3) and the guide portion (9) is disposed on the outermost side of a transfer port (34) with which the transfer passage is in communication when the piston (3) is in a retracted position. In the master cylinder assembly separate master cylinders are connected by a common transfer passage (30) through which the pressure spaces (28) of the master cylinders in advance of pistons (3) are in communication when the master cylinders are operated simultaneously, and communication between the pressure spaces (28) is cut off by a transfer valve mechanism (33) when one of the master cylinders is operated on its own. <IMAGE>

Title: A closure device for a container having a cylindrical opening
IPC: B65D50/04
Filed: 1982-06-04
Abstract: The invention relates to a closure device 1 such as a screw cap for a container such as a medicine bottle having a screw neck, the device 1 having inner and outer caps 2 and 3 comprising respectively an end member 4 and 5 and a skirt member 6 and 7, there being first drive means 8 between the skirt members 6 and 7 and second drive means 9 associated with biassing means 10 in the form of a resilient ring formed integrally with the outer cap 3. In order to tighten the device 1 on a bottle, the outer cap is rotated, the first drive means comprising ratchets 12 and driving dogs 13 driving the caps in unison. If the outer cap is now unscrewed, the ratchets 12 click over the dogs 13 and the inner cap is not unscrewed until the outer cap is depressed to overcome the force of the ring 10, which normally acts to bias the caps apart, so engaging dogs 15 in sockets 14 comprising the second drive means. The two caps can then be unscrewed in unison.   <IMAGE>

Title: Soap bars
Inventor: SUBBA RAO BOOKINKERE CHENNAKES
IPC: C11D9/02
Filed: 1982-08-27
Abstract: Soap bars comprising at least 30% by wt of tallow scrap and 3-30% by wt of water soluble hydroxy stearic acid salts are obtained by using castor wax (hydrogenated castor oil) acids as substitute for the nut oil derived acids normally used in soap formulations. Castor wax is preferably utilised as a soap feedstock by ensuring the weight proportions of hydroxy- stearic acid (the major ingredient of castor wax acids) relative to oleic and lauric acids are within specified limits.

Title: Water heating apparatus
Inventor: JAMES JOHN FREDERICK COLSTON
IPC: F24H9/18
Filed: 1982-09-09
Abstract: Water heating apparatus of the invention comprises an inlet section (10, 140), an outlet section (11, 141) and a body (14, 139) between the two sections, the body (14, 139) containing a heater unit (26, 45, 124, 134, 137, 142, 149, 151, 155, 156, 160, 161, 162) including printed circuit heater means. In a preferred embodiment the heater unit (26) is in the form of a printed circuit heater (27) sandwiched between a pair of metal plates and rolled into a spiral. This gives a large contact area for water flowing around the spiral as well as an increased contact time, thus giving improved heating efficiency. In addition the printed circuit heater can be kept relatively short and compact, so that the water heating apparatus itself does not become bulky or expensive.

Title: Plant pots
Inventor: HUTCHINSON PHILIP
IPC: A01G9/10
Filed: 1982-12-16
Abstract: A plant pot 1 comprises a cylindrical body 2 of circular cross- section, which is slit along its length so that it may be expanded and compressed radially. A constraining ring 3 passes around the body 2. In use, a Dahlia tuber is planted within the plant pot 1, in suitable compost. As it grows, the tuber expands in the plant pot 1 and becomes increasingly constrained under pressure therein. To remove the tuber from the plant pot, the constraining ring 3 is removed from around the cylindrical body 2, whereupon the pressure of the plant pot 1 upon the tuber is sufficiently released to allow the tuber to be removed. The plant pot 1 may be used to grow Dahlias of consistent and uniform appearance, and with reduced likelihood of afflictions. <IMAGE>

Title: Fluid dispenser
Inventor: RUTTER CHRISTOPHER C
IPC: B67B7/18
Filed: 1983-10-24
Abstract: A fluid-dispenser for a bulk container for potable liquids such as wine comprises a tubular filling and dispensing gland 42 welded around a hole in a laminated plastic bag 24, a sealing cylinder 56 having a diaphragm 58 at an oblique angle that seals its inner end and a tubular dispensing member 66 with a sharp cutting edge 74 at a corresponding oblique angle.

Title: Thickening coal washery tailings
Inventor: LLEWELLYN LYN ILLTYD DAVIES
IPC: B01D57/02
Filed: 1984-07-16
Abstract: The tailings from a coal washery are fed to apparatus where they are subjected to a DC potential, thereby generating electrophoresis, which is used as an aid to drainage. In a batch process the tailings are delivered to a settling pond 1 whose base has a metal grid 2, 3, 4, 5 providing the cathode, the anode being lowered in to be immersed in the tailings. The base of the pond filters out the water to a drain 8. In a continuous process, the tailings are fed to a pressure vessel which has a wall (12) or walls (34) that are water permeable, the partially dehydrated tailings being directed further downstream to a controllable outlet (20, 39). The throughput of tailings can be controlled by governing the feed pressure, compressed air admitted to the vessel, and/or the degree of opening of the outlet. The water permeable wall portion may form the cathode for the DC potential, while an anode (19, 43) is suspended within the vessel. An alternative (Fig. 8) employs belt filtration, the belts (46, 47) serving as an anode and a cathode, the lower one (46) being the cathode and being water permeable. <IMAGE>
