Patent GB-657022-A (GB)
Title: Improvements in or relating to closures for cans or like containers
Inventor: LOFTS SIDNEY EDWARD
IPC: B65D55/08
Filed: 1947-04-01
Abstract: 657,022. Hollow-ware; closures. WELLSEALS, Ltd. April 1, 1947, No. 8804. Divided out of 651,514. [Classes 66 and 125(iii)] In a can or like container in which the closure member 49 is provided with a sealing ring 50 so secured in a groove 51 around the opening in the top ring 48 of the can that the sealing ring must be damaged before the closure member can b e removed, the groove 51, as seen in cross-section, slopes outwardly from the axis of the opening so as to expand the flange of the sealing ring pressed into it. As shown, Fig. 3, the base of groove 51 abuts the wall of the can for support during the pressing operation. The groove may also receive a complete or part ring 52 formed with a spout 53 which, when the opening in the top ring is eccentric, can be moved round from a position for pouring. The axial flange 75 of the sealing ring may be plain or, as shown, Fig. 5, notched, a weakening notch 74 also being provided opposite a slit 77 in the flange so that the ring can be broken by lifting a tab 72. Specification 480,338, is referred to.
Patent GB-704228-A (GB)
Title: Improvements in or relating to circuit-arrangements for use in automatic signalling systems
IPC: H04M1/515
Filed: 1952-04-07
Abstract: 704,228. Automatic exchange systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 7, 1952 [April 10, 1951], No. 8820/52. Class 40 (4) [Also in Group XXXVIII] In a system, e.g. for signalling digital information from a subscriber to a telephone exchange in which signals are transmitted to a receiver over a line loop by changing the value of the resistance inserted at the distant end of the loop, one leg a of the loop is connected to battery at the receiving end and the other leg b is connected to the cathode of a valve B1 the control electrode of which is fed with such a potential that the cathode remains substantially at earth potential irrespective of the value of the resistance inserted in the loop. This arrangement minimizes the errors due to leakage to earth in the line loop. Thus the current through the leak resistance of the leg b unlike that of the leg a passes through the signal receiver and may produce an erroneous operation therein. By maintaining the cathode of B1 at earth potential no current through the leakage resistance Rb of the leg b is permitted. The valve B 1  behaves as an earthed impedance equal to the reciprocal of its mutual conductance which is small compared with the values of the signalling resistors Rk1 ... Rk10 so that changes in current due to changes in these resistors produce only a small change in its cathode potential. This small change is however further reduced by the use of a negative feed backcircuit incorporating the valve B 2 . Changes in signalling current produce corresponding changes in voltage across the anode resistor R 1  which are detected by a known signal detector OI.

Filed: 1946-03-22
Abstract: 609,784. Vanity cases. ROSENFELD, M. Y. March 22, 1946. No. 8894. [Class 18] [Also in Group VII] In a vanity box of the kind in which a casing having a number of compartments forms part of a bracelet, the compartments are formed in a blank or block secured in a frame to which curved wrist bands are hinged. The box is made from a rectangular block 5 of the material known under the Registered Trade Mark "Bakelire," for example. Formed in its upper surface is a circular cavity 6 for face powder, a filter screen 7, and a powder puff.

Patent GB-716960-A (GB)
Title: Apparatus for mixing liquids for treatment thereof and then separating them
IPC: C11B1/10
Filed: 1951-04-17
Abstract: <PICT:0716960/III/1> An apparatus for treating a first liquid, such as a miscella having "fines" or colloids in suspension, with a second liquid, such as a coagulant solution, and for separating the treated liquid from treating liquid comprises a series of chambers, interconnected in series through weirs permitting flow of liquid from the first chamber of the series to the last chamber of the series, and provided with means to admit both liquids to the first chamber of the series, means to draw the treated liquid from the last chamber of the series, and means to return the treating liquid to the first chamber of the series.  The treated liquids may comprise miscellas or like liquids, such as solvents containing oils or fats leached from seeds, nuts &c. having minute solid particles and colloids held in suspension therein.  The coagulant solution precipitates both the "fines" and the colloidal matter.  Filtering of the miscellas and fouling of the evaporators when removing the solvents are thus avoided.  Any known coagulants, such as ferric chloride, may be used; a solution of alum in water is preferred.  A suitable apparatus for use when the miscella is lighter than the coagulating liquid comprises a closed tank A divided into compartments B . . . E with outlets N . . . N3 at the base thereof for the coagulating liquid mixed with the precipitated "fines" and colloidal matter, together with a pump F for circulating the coagulating liquid back to the top of the first compartment B of the series.  The coagulating liquid discharges against a baffle into a funnel J, to which the miscella to be treated is supplied through pipe H and further coagulating liquid if desired from a funnel Q.  The miscella rises in the compartment B and the coagulating liquid falls to the bottom.  The miscella eventually overflows through pipes L . . . L2 in successive settling compartments C . . . E to be removed through pipe M, any retained coagulating liquid with impurities settling out and falling to the bottom.  The exhausted coagulating liquid can be removed from the system by closing a cock O and opening a cock P which goes to waste, the liquid being replaced through the funnel Q.  In a modified settling tank for use when the miscella is heavier than the coagulating liquid the same system is employed with overflow pipes for the miscella connected near the base of the compartments and overflow pipes connected to the outlets N . . . N3 extending to the coagulating liquid layers, now at the top of the compartments.

Title: Tubular pit props, piles, arched roof supports and the like
IPC: E21D15/02
Filed: 1931-03-27
Abstract: 367,218. Mine roof supports ; piles. BROMFORD TUBE CO., Ltd., Wheelwright Road, Erdington, Birmingham, and SPENCER, R. W., Rothwell, Walmley Road, Sutton Coldfield. March 27, 1931, No. 9337. [Class 20 (ii).] A non-telescopic tubular pit prop, pile, arched roof support for mines, and the like, is packed with granular material and has its ends sealed and treated so that the granular material is further compressed. The sealing may be effected by a pressing operation after heating the end of the tube to a welding temperature, this operation resulting in a thickening of the wall of the tube at that end. According to one method, a pit prop is formed by heating one end of a tube to a welding temperature and applying to it a die so shaped as to bring this end to a point or rounded surface, as shown in Fig. 1. The walls of the tube are adapted to unite under the pressure of the die. The tube is then packed tightly with sand and the other end is then pointed or rounded in a similar manner. One end of the tube is again heated and placed in a die the walls of which encircle but are spaced clear of the tube. A male die is then forced into this tube-holding die and its operating surface is such as substantially to flatten the end of the tube and to spread the metal out laterally in the form of a flange as shown in Fig. 2. This operation places the sand under further compression. Plugs may be inserted in the tube to compress and support the sand during the end-closing operations. In a modification, an arched roof support, Fig. 4, has rounded ends 5 and is formed with ridges 2 adjacent each end. These ridges are formed by means of dies after the ends of the tube have been sealed, and serve to form abutments for sleeves 4 which are used to connect the roof support 1 with a supporting member 6. A tube for a pile may be packed partly with a non- granular material. Thus, the lower pointed end of the pile may be packed with concrete or cement, with the compressed granular material disposed above it.
