Title: Hormone-Like Preparations Derived from Thymus Gland and Methods of Producing the Same.
IPC: A61K35/26
Filed: 1967-08-17
Abstract: 1,195,980. Active thymus gland extracts. YESHIVA UNIVERSITY. 17 Aug., 1967 [24 Aug., 1966], No. 37903/67. Heading A5B. Hormone-like extracts of thymus gland called "Thymosin" and "anti-thymosin" are obtained by homogenising thymus glad tissue in saline, centrifuging and treating the supernatant with acetone after heating to 100‹C. for 15 minutes to produce a precipitate containing the thymosin and a supernatant containing the antithymosin. The precipitate may be worked up by passing its solution in 0.15M NaCl through a polyacrylamide gel column, lyophilization of the percolate and fractionation of a solution thereof in phosphate buffer on a DEAE-cellulose column. The supernatant may be worked up by passage of an aqueous solution of the lyophilizate thereof through a polyacrylamide gel column. "Thymosin" is stated to stimulate lymphoid tissue proliferation, "anti-hymosin" to have the opposite effect.

Abstract: 1,192,555. Piston and connecting-rod assemblies. GLACIER METAL CO. Ltd. 31 July, 1967 [24 Aug., 1966], No. 37943/66. Heading F2T. In a piston and connecting rod assembly of a two-stroke internal combustion engine comprising a gudgeon pin 5 secured to the piston 4 and journalled in a plain bearing 3 in the connecting rod small end 2, in order to ensure adequate lubrication of the bearing 3, the thrust load thereon is relieved during a part or parts of the engine cycle by struts 9 located between thrust surfaces 8 and 10 on the gudgeon pin 5 and connecting rod 1 respectively, the surface 8 being displaced from the gudgeon pin axis 5B so that during operation the distance between the surfaces 8 and 10 varies, whereby during said part or parts of the engine cycle the struts 9 are compressed and exert a force in opposition to the gas pressure load on the piston. The gudgeon pin is secured to the piston by bolts 6 and the thrust surfaces 8 and 10 are formed by hemi-spherical sockets in flat surfaces 7 on the gudgeon pin and abutments 11 on the connecting rod respectively. In the embodiment shown, the sockets 8 are on the side of the gudgeon pin axis 5B remote from the piston crown 4A so that the struts are in compression and oppose the bearing load when the connecting rod is in the top dead-centre and lower dead-centre regions. In a modification, Fig. 4 (not shown), the sockets (8A) are nearer the piston crown (4A) than the gudgeon pin axis (5B) so that the bearing load relief occurs in the half piston stroke regions.

Title: Improvements in or relating to mechanism for registering sheets being fed to printing machines and the like
IPC: B65H9/10
Filed: 1946-12-30
Abstract: 619,813. Feeding sheets. LINOTYPE & MACHINERY, Ltd., and ROWLANDS, T. Dec. 30, 1946, No. 37982. [Class 100(i)] In a sheet-feeding device for printing and like machines, the sheets are registered laterally by means of a slidable member 27 formed with a projection 28 which is made to engage the side edge of a sheet being fed as a support 25 is moved inwards from the position shown in Fig. 2 until the slide 27 is arrested b y engagement of the projection 28 with the edge of the sheet. The slide 27 is of dovetail shape and slides in guides in a support plate 2-5 attached to an extension plate 26 of a reciprocating carriage 12. The sheet is held to the slide 27 by a gripper member in the form of a roller 16 mounted on a lever 15, and as the support 25 is moved outwards the projection 28 engages a fixed side gauge 29 which arrests the slide 27 with the sheet correctly registered as shown in Fig. 5. The mechanism is supported by an adjustable clamp 1, and operated by a shaft 7 which is mounted similarly to the shaft of the side-registering device described in Specification 501,364, and is moved inwards by spring action and outwards by a Bowden wire or like member 23 operated by a cam on the printing-machine. As the support 25 moves inwards the cam roller is held raised by the action of a collar 9 upon the end 17 of gripper lever 15, but when the support moves outwards a collar 18 pressed by a spring 19 moves the gripper on to the sheet. The gripper lever may be detachably mounted so as to be replaceable by levers which exert a different pressure so as to deal with sheets of different thicknesses, or it may be mounted about an eccentric which can be adjusted to vary the gripping pressure. The sheets are guided into position by pivotally mounted guides 31 which are raised to an adjustable extent by outward movement of the reciprocating carriage 12 which supports the registering devices, and the guide 31 nearer to the printing- machine is given an extra movement so as not to impede the travel of the sheet towards the machine.

The direction of winding of the cable or band 18 is such that in the normal forward drive from the driving shaft 1 to the driver 2 no drive is transmitted thereby but when the driven shaft tends to drive the driving shaft 1 the coils are tightened on the drum 17 to effect a drive. The arc enveloped by the coils and the tension of spring 20 is calculated to transmit a torque slightly greater than the maximum resistant torque of the engine and less than a limiting value which might damage the transmission.
