Title: Device for filling receptacles with cigarettes and like rod-shaped articles
IPC: A24C5/354
Filed: 1959-04-14
Abstract: 921,153. Filling cigarette containers. AMERICAN MACHINE & FOUNDRY CO. April 14, 1959 [June 20, 1958], No. 12700/59. Class 94(1). [Also in Group XXX]. A device for depositing cigarettes issuing from a cigarette making machine into containers for use in a packaging machine, comprises a conveyer belt having a horizontal and a vertical run, and a further belt parallel to the vertical run, the lower ends of both vertical runs being moveable horizontally and vertically to discharge and distribute cigarettes in the containers. Cigarettes on a belt 2 are pushed on to a belt 6 by a plunger 4 to form two rows, the opposed end of which are engaged by a member 18 and belts 22, 24 to ensure alignment of the ends in each row. Each row is received by a belt 32 which has a horizontal feeding run over pulleys 34,36, a vertical run round pulleys 36,38 40 and a return run round pulleys 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 34. The pulleys 44, 48, 52, 56 are carried on a vertically slideable member 43 and pulleys 36, 40 are mounted on a horizontally traversing carriage 60. The vertical belt 68 is also mounted on the carriage 60 and its pulleys 63, 66 and pulley 38 are arranged for vertical movement relative to the carriage. When the carriage 60 moves to the right, as shown, or the pulleys 38, 63, 66 are raised, movement downwards of the member 43 retains the belt 32 taut. At the commencement of filling an opensided container 70, the discharge point between pulleys 38, 66 is at the bottom left hand corner, as shown in Fig. 2, and traverses to the right. The speed of return to the left is such that no cigarettes are deposited, the discharge run of the belt 32 lengthening at the same speed. The discharge point reciprocates and is raised by steps until the container is full. An empty container is indexed into position during a return run. The descent of the discharge point into the new container is at such a speed as to prevent deposit of cigarettes by lengthening of the vertical run of the belt 32, until the bottom of the container is reached. The containers are brought into filling position by a conveyer 86 which is sloped to ensure that cigarettes rest against their closed sides. During filling, the containers are given a slow movement (see Group XXX) to the left as shown in Fig. 3 to ensure depositing of the cigarettes adjacent the closed sides. The rapid indexing movement is initiated when the final upward step of the pulleys 38, 66 operates a switch, Fig. 4 (not shown). Flaps 74, 75 adjacent the belt discharge are movable to guide cigarettes into the container carriers at the extremes of belt travel. U.S.A. Specification 2,124,397 is referred to.

Abstract: A composition for friction facing material, e.g. for clutches or brakes of vehicles consists of 55 to 90% iron, 5-30% graphite and 5-24% thermosetting resin.  The composition as it is cured may be simultaneously attached to a backing, e.g. a brake shoe, if desired with the use of a resin adhesive which is cured at the same time as the binder resin.

Title: Process for obtaining alkali metal cyanides
IPC: C01C3/10
Filed: 1964-03-26
Abstract: In a process for preparing alkali metal cyanides by neutralizing an alkaline solution with gases containing, besides hydrogen cyanide, at least one of ammonia, steam and carbon dioxide, the gases are treated with the alkaline solution, which may contain cyanide, in a film apparatus, which may be cooled, the gases and solution being in parallel flow, the temperature of the solution reaching at the highest 90 DEG  C., the final temperature of the gases being near that of the solution, the contact time of the gases with the solution being not greater than 2 or 3 seconds and preferably less than one second, and the contact time of the solution with the gases being a few seconds, for example 5 to 6 seconds.  Preferably, the vapour tension of the solution leaving the apparatus is higher than or equal to the partial pressure of the steam in the gases leaving the apparatus.  The temperature of the inlet gases to the apparatus may be between room temperature and 300 DEG  C. The process may be carried out either discontinuously, by neutralizing a strongly alkaline solution by contact with the gases during several cycles of the solution through the apparatus; or continuously, by use in the apparatus of a constant concentration alkaline solution which is recharged with alkali metal hydroxide after leaving and before being recycled to the apparatus. A suitable film apparatus is described and illustrated, and its use exemplified in the production of sodium cyanide.

Title: Improvements in the continuous measurement and recording of the conductivity of electrolytic solutions
Inventor: GOITEIN KARL
IPC: G01N27/04
Filed: 1952-05-23
Abstract: 781,058. Electric tests. ELLIOTT BROS. (LONDON), Ltd. May 26, 1953 [May 23, 1952], No. 13195/52. Class 37. The conductivity of a solution is measured in an A.C. bridge which is automatically balanced for resistance, the component of the unbalance current produced by the capacitative part of the solution, being neutralized by current from an auxiliary bridge fed with A.C. at 90 degrees to the A.C. feeding the main bridge. As shown, a first A.C. bridge 3 is fed from a transformer winding 22 and comprises a test conductivity cell represented by resistor 35 and capacitor 36 in one arm, a standard conductivity cell represented by resistor 33 and capacitor 34 in another arm, and a potentiometer 31 whose slider 32 divides it into the other two arms of the bridge. The unbalance current is fed via an amplifier 5 to a 2-phase servomotor 6 which moves the slider 32 to rebalance the bridge. Any out-of-phase component of the unbalance current is neutralized by the unbalance current of an auxiliary bridge 4, fed with out-of-phase A.C. the difference being fed via amplifier 5 to a second 2-phase servomotor 7, whose reference winding 71 is fed with in-phase A.C., so that the outof phase component of the total unbalance currents causes motor 7 to rotate and move the slider 44 of potentiometer 43 of bridge 4 to the balance position. Thus the position of slider 32 indicates the conductivity of the solution in the test cell by reference to the standard cell. Temperature compensation is effected by locating the standard cell in a sealed container in the test solution, or by introducing thermistor elements into the bridge circuits.

They may be prepared by reacting mercaptoacetic acid with an appropriate aldehyde or ketone, either in one stage or via an intermediate thiometal or thioacetal which is then heated to effect ring closure.
