Title: Improvements in or relating to perforators for telegraph apparatus
IPC: H04L17/20
Filed: 1963-08-01
Abstract: 1,038,516. Selective punching apparatus. TELETYPE CORPORATION. Aug. 1, 1963 [Aug. 16, 1962], No. 30549/63. Heading B4B. Punching apparatus comprises a plurality of punches 82 each connected through a pivotallymounted lever 55 to a spring-urged pawl 73 to which a spring-urged pivotally-mounted sensing lever 42 is capable of being latched, a plurality of code elements 20 to be sensed by the levers 42 to permit selected levers 42 to move into latching engagement with certain ones of the pawls, and a pivotally-mounted driving bail 56 for moving latched levers and pawls to cause the corresponding punches to perforate a record tape. The levers 42 have tines 43 for sensing tines 41 on the elements 20 which take the form of extensions of selectively settable code bars 137 of the printer described in Specification 1,021,027. The bail 56 is operatively connected to an oscillatable main drive shaft 21. During clockwise oscillation of the shaft 21, Fig. 4, bail 56 is moved upwardly in a clockwise direction away from lugs 57 on the levers 42 so that the levers rotate counterclockwise under the action of springs 48. Those of the levers whose tines are not blocked by the tines on the elements 20 move upwardly until shoulders 75 on projections 70 of the levers are above shoulders 74 on associated pawls 73, whereupon springs 76 move the pawls clockwise, Fig. 4, to snap the shoulders 74 under the shoulders 75. At this juncture, the bail 56 is moved counterclockwise, Fig. 4, to engage the lugs 57 on the selected levers 42 and drive them downwardly with their latched pawls. This movement of the latched pawls pivots the associated levers clockwise to drive the corresponding punches upwardly to perforate the record tape. After the punching operation, the bail 56 is moved clockwise, Fig. 4, and a spring-urged stripper bail 92 unlatches the latched pawls from the associated levers and exerts an upward force on the pawls tending to return the punches. If a punch has not returned under the combined forces of the bail 92 and springs 48 and 76 acting on the levers 55, the bail 56 engages a cam surface 96 on the corresponding pawl. The tape is fed by rollers 100, 112, the roller 100 being moved incrementally by means of a ratchet-wheel 101 engaged by a spring-urged pivotally-mounted pawl 102 connected to one, 58, of the arms 58, 59 carrying the bail 56. A pivotally-mounted cam-operated nudger lever 127 pulls a loop from a roll of tape once in each punching cycle. Attached to punch die block 85 is a chip collecting trough 86 having a shoot 87. The elements 20 may, alternatively, be moved by magnet controlled mechanism.

Title: An improved lubricating grease composition
Filed: 1945-11-19
Abstract: Low temperature lubricating greases comprise one or more compounds having the formula COOR1(R)COOR2, where R is a bivalent aliphatic hydrocarbon radical and R1 and R2 are branched chain hydrocarbon radicals; an alkali or alkaline earth metal soap and a stabilizer, i.e. a material used to improve the mechanical or physical stability of the grease.  R may be a polymethylene radical having 8 methylene groups, as in sebacic acid, and R1 and R2 may be 2-ethyl hexyl radicals or secondary butyl radicals.  The esters may contain additional constituents or functional groups.  The proportion of soap present may be 6-30 per cent and the lithium soap of hydrogenated fish oil acids is preferred.  The proportion of stabilizer may be 0.5-5 per cent, e.g. 1 per cent of the soap of an amphoteric metal. The esters may be di-2-ethylhexyl sebacate or a mixture of this with di - secondary butyl sebacate, 1-isobutyl-2-ethyl hexyl sebacate, or a mixture of di-secondary butyl adipate and di-isopropyl sebacate. In an example, 12 per cent lithium soap of hydrogenated fish oil acids, 0.5 per cent aluminium stearate, 0.5 per cent zinc naphthenate and 87 per cent of 2-ethyl hexyl sebacate were mixed together, heated to 360-400 DEG  F., rapidly cooled by running over a drum, chilled and worked to the desired penetration.  The resultant lubricating grease shows considerably less evaporation at elevated temperatures and less resistance to torque at very low temperatures than conventional low temperature lithium soap greases made with low viscosity petroleum distillates.

Title: Improvements relating to electrically operated indicating instruments
Inventor: SNELL MAURICE SAXON
IPC: G08B5/22
Filed: 1952-12-08
Abstract: 731,967. Electrically operated indicating instruments. DOWTY EQUIPMENT, Ltd. Nov. 27, 1953 [Dec. 8, 1952], No. 31081/52. Class 3(1). An indicating instrument comprises a a plurality of prisms 49, preferably of equilateral triangular cross section, mounted side by side on parallel axes 50 pivoted at their ends, with driving mechanism for simultaneous rotation of the prisms to bring their corresponding faces in turn into a display position wherein the faces displayed are co-planar, and electro-magnetic means including an armature to operate the driving mechanism. As shown the instrument has a cylindrical casing 10 with a square box-like head 12 fitted with a transparent window 11 and is held against a panel 13 by means of a spring 16, bearing against a retaining ring 17 and pips 18. The driving mechanism consists of a U-shaped rack 46 with teeth 48 along the tops of its two sides, these teeth engaging those of gear wheels 53 mounted on the axes 50 of the prisms 49, the rack being slidable and operated by the peg 44 which is attached to the armature arms 38, 39. The armature consists of the two arms 38, 39 projecting from the U-piece 37, the legs 42 of which are pivoted by pins 43 in a yoke 23 of magnetic material which is secured to an insulating base 22. The cores 26, 27 of two electromagnetic coils 28, 29 are secured to the web of the yoke 23. When neither coil 28 nor 29 is energized the peg 44 is in a central position and one set of faces of the prisms 49 is displayed. When coil 29 is enerzed the arm 39 is attracted to the pole piece 41 of the core 27, the armature pivoting about pins 43. This moves peg 44 and causes the rack 46 to move laterally, so rotating the prisms 49, when another set of faces is displayed. The de-energizing of coil 29 and energizing of coil 28 displays the third set of faces of the prisms. Springs 57 return the rack 46 to the central position when neither coil is energized. The extension of the arms 42 beyond the pivots 43 balances the armature, also the width of the arms 42 is less than that of the yoke 30 (see Fig. 3) to avoid adverse magnetic effects. In another embodiment, the instrument may have a single electro-magnetic coil and a permanent magnet armature which is displayed to one side or the other of its neutral position according to the direction of the current in the coil.
