Title: Method of and apparatus for packing articles with separators
IPC: B65B61/22
Filed: 1966-04-12
Abstract: 1,116,271. Packaging-machines. COMPAGNIE DE SAINT-GOBAIN. 12 April, 1966 [9 April, 1965], No. 15992/66. Heading B8C. Apparatus for inserting partitions into cartons previously loaded with articles with rounded shoulders comprises mechanisms 1, 3 which insert the longitudinal and transverse partitions 4, 21 respectively as the carton is fed past them. The articles, e.g. jars, are inserted in the carton in a conventional manner, e.g. suction gripper heads, and are fed to a position 1a. The carton trips a microswitch M 1  and a pusher P 1  thrusts a partition 4 through a slot in the base of the magazine S and into the carton. The carton progresses to a position 2a and trips a microswitch M 2  and an inclined plate P 2  descends and pushes the articles to the front of the carton to assure transverse alignment of the jars. The carton progresses to a plate P 22 , operating a contact (not shown), causing a piston-rod P 3  to be slowly extended in the conveying direction. Mounted on the piston-rod P 3  is a slide C 14 , and adjustably positioned cams 16- 19 which activate a valve V 4  causing a pusher 14 to thrust a transverse partition into the carton every time the valve V 4  is activated, e.g. four times in the embodiment. When the piston-rod P 3  is fully extended it trips a microswitch M 4  causing the plate P 21  to be withdrawn and allowing the carton to move away. To facilitate insertion of the partitions, the slots therein may be V-shaped.

Title: An improved method of and apparatus for exerting a force on a body rotating about a fixed axis
IPC: G01M1/30
Filed: 1960-05-06
Abstract: 956,443. Balancing shafts. COMPAGNIE DE SAINT-GOBAIN. May 6, 1960 [May 6, 1959], No. 16074/60. Heading F2U. [Also in Divisions B3 and G1] A balancing force is exerted on a body rotating about a fixed axis by applying an electromagnetic force to the body in a direction making a predetermined angle with the axis of rotation of the body, the intensity of the force being adjusted to the desired value or controlled in accordance with a predetermined law by varying the electric current producing the force. An electromagnet 2, Fig. 2, is carried by an arm 3 fixed to a rotating shaft 1, current being supplied to the electromagnet by brushes. The electromagnet 2 travels within a ferromagnetic ring 4. By making the internal surface of the ring 4 non-circular the force is varied during one revolution of the shaft. The electromagnet 2 and arm 3 are balanced by a mass 6. The electromagnet 2 and ring 4 may be inclined as shown in Fig. 3. In a modification, Fig. 5, the arm 3 carries a member 7a and a circular array of stationary electromagnets 2 is provided. In a further modification, Fig. 7, the shaft 1 carries a disc 8 having a ferromagnetic rim, and a single electromagnet 2 is provided. Several electromagnets may be arranged around part only of the circumference of the disc. Glass-polishing apparatus, Fig. 8, comprises a shaft 9 driven by a motor 10 and having a crank 11 carrying a polisher 12 comprising rouge-impregnated felt 13. Any change in the coefficient of friction between the felt and the glass 14 alters the power demanded of the motor 10 and this is used to vary the electromagnet energizing current.

Title: Mounting for telescope mirrors
IPC: G02B23/16
Filed: 1952-06-26
Abstract: 723,369. Mounting reflectors ZEISS OPTON OPTISCHE WERKE OBERKOCHEN GES: June 26, 1952 [June 29, 1951], No. 16125/52. Class 97 (1). To avoid distortion in plane or curved mirrors of reflecting telescopes due to the weight of the mirror the latter is mounted at its margins in a mounting body shaped to provide an enclosed hollow-space between it and the rear of the mirror, the pressure of the gas filling this space being automatically regulated so as to compensate the component of the mirror's weight perpendicular to its surface for every position of the mirror. As shown, the mirror a is mounted by a rubber ring b and clamping ring c1 in a mounting body c providing a hollow space communicating by a boring d1 and tube h to a bellows g compressed by a ring-shaped weight f freely slidable along an axis d coincident with that of the mirror. The pressure of the weight f on the bellows varies with the inclination of the mirror a to the vertical and so automatically adjusts the pressure within the space to compensate the weight of the mirror. By choice of a gas of a suitable density, such as sulphur hexafluoride, to fill the space, distortion of the mirror in its vertical position may be compensated.

Filed: 1970-04-07
Abstract: 1,242,982. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 7 April, 1970, No. 16397/70. Heading H4K. In an automatic telephone system a cord circuit is connected to a remote operator's position through one or more switching stages and signals are sent by the operator to set the cord circuitry into conditions for communicating with the called or calling party or both or to monitor the connection. A call requiring the operator is routed to cord circuit CC through exchange switches A and is connected to an operator through a transformer (TR2) having one pair of its three pairs of windings connected to switch MX. It is stated that the operator may set up a call by switches B to the required party. The operator may listen and speak to one or both parties by switching a potential on to the centre-tap of the windings of a hybrid at the operator's position, Fig. 4 (not shown). This potential is sensed in the cord circuit, Figs. 2 and 3 (not shown), and causes the state of transistors to alter accordingly to give the following states. Monitor.-Potential of -12 v. applied causing the signal in the third pair of windings of transformer TR2 to be amplified and applied to the operator's headset. Speak.-Potential of + 6 v. applied causing some of the line current to be directed through the first pair of windings of transformer TR2 without interrupting the through transmission. The operator's microphone circuit is energized. Speak ANS.-Potential of +12 v. applied causing all the line current to be diverted into the first pair of windings of TR2 and the called connection effectively disconnected by terminating the called end of the cord circuit in an appropriate impedance. Speak call.-Potential of - 12 v. applied but causes a higher current than the monitor current to apply an appropriate impedance at the input of the cord circuit effectively disconnecting the calling subscriber. The third pair of windings of TR2 carries the whole line current in this case.

IPC: C01B31/30
Filed: 1957-05-28
Abstract: An intimate mixture of a titaniferous ore, e.g. Ilmenite, Perovskite, or Sorel slag, and coke, e.g. petroleum coke, optionally together with sawdust and water, is heated in an Acheson-type resistance furnace, preferably with a substantially constant power input, to a temperature of at least 1500 DEG C., and the crude titanium carbide product thereby produced is cooled, crushed, preferably to lumps of 1/4 -3 inch diameter, and leached with aqueous hydrochloric or sulphuric acid having a pH of not more than 3.  In the Acheson-type furnace heating is effected by passage of an electric current through a central core of carbon extending between two electrodes, the charge being packed around said central core.  In the leaching step the acid may be passed upwards through the crude carbide, and recycled a number of times maintaining the pH at a value below 3, preferably of 2-3, until reaction is complete.  Three examples for the treatment of Perovskite, Ilmenite and Sorel slag, respectively, are given. Specification 867,205 is referred to.

The grain enters through the opening 8, is forced against the baffle 11 and then passes over an horizontal sieve 13 and a plate 14 to the second baffle 15 which may be adjusted and locked in the desired position by a pin 16. The baffle 15 may be provided with a fluted edge. A second sieve 17 is arranged behind the baffle. A wedge-shaped projection 10 is situated in the upper part of the drum to force the straw along the drum to the further beating and straw-reducing devices comprising rotating fingers 6 co-operating with fixed fingers 7. The fingers are trapezium shaped in cross-section and are obliquely fluted on their sides and edges as shown on Fig. 5. They may be exchangeable and adjustable and may have an asymmetric cross-section. An adjustable end plate with a detachable rim 21 is fitted between the beaters 6 and a flywheel 25 carrying wind vanes 33 and distributing forks 31, both vanes and forks being adjustable.
