Title: Improvements in or relating to apparatus for mechanically operating keyboards of typewriters and the like
IPC: B41J29/393
Filed: 1944-02-03
Abstract: 576,600. Typewriters &c. CREED & CO., Ltd., and DREWELL, W. B. Feb. 3, 1944, No. 1978. [Class 100 (iv)] Apparatus for mechanically operating the keyboard of a typewriter or the like for testing purposes, comprises actuating members 11 for the respective keys supported above the keyboard and reciprocated towards and away from the keys, and means for allowing only a selected actuating member to actuate its corresponding key consisting of a set of notched combination bars 16 arranged transversely of the actuating members. All the keys may be actuated in any desired sequence or a limited number of keys may be operated any desired number of times. The actuating members 11, Fig. 9, are mounted on L-shaped members 12 each pulled downwardly by a spring 15 and are normally kept raised by the engagement of projections 13 thereon with a common bail 14. Slidable transversely in guides 17, Fig. 4, beneath the horizontal arms of the members 12 is a series of notched combination bars 16, the setting of which selects the member 12 which is to operate. Springs 19, 20, urge the bars 16 into engagement with wards 24 on a drum 23, which determine the setting of the bars. Theapparatus is driven from an electric motor 29 coupled to a cam-shafts 28. In operation, a cam on the shaft 28 first actuates a lever 18 to withdraw the bars 16 to the left, Fig. 4, and then another cam turns the drum 23 one step through ratchet- and-pawl mechanism 38, 39 to present a new ward 24 to the bars 16 which are reset thereby when released by the lever 18. Further cams 25 now operate on arms 42 to allow the bail 14 to fall and thus permit the members 12 under the action of springs 15 to engage the bars 16 which form abutments for all the members except the selected member which continues to move downwardly in aligned notches to actuate the corresponding key. The wards are readily interchangeable so that any desired sequence can be made. A revolution counter is actuated from the shaft of the drum 23. The apparatus is set initially by a handle which can be coupled to the motor shaft, a spot on a disc fixed to the shaft 28 being visible through an opening in the casing when such position is reached. The tension of the springs 15 can be adjusted by a hand wheel 60 turning a screwed shaft 56 on which rides a nut 57 fixed to a bar 53 to which the springs are attached. A tension indicator 61 is actuated from the nut 57 through a lever 62. As an alternative to the drum 23 and wards 24, a perforated tape may be employed which, in the case of a paper tape actuates the bars 16 through interposed levers.

Title: Improvements in or relating to crusher plates for jaw crushers and the like
IPC: B02C1/10
Filed: 1939-12-06
Abstract: 537,289. Jaw crushers. NORDBERG MANUFACTURING CO. Dec. 6, 1939, No. 2032/41. Convention date Dec. 12, 1938. Divided out of 537,117. [Class 59] A crusher plate for a jaw crusher has a rearward wedge-shaped extension which fits into a complementary recess in the jaw, the plate being held in place by bolts. The plate may be made of manganese steel and may be flat, as shown at 12, or curved as shown at 12a. Instead of manganese steel, any metal having the same ductility and the same resistance to wear and abrasion may be used. Each plate is provided on its back with a wedge-shaped extension 15 which is provided with an insert 20 of metal preferably less ductile than manganese steel. The extension fits into a complementary recess 10 in the crusher jaw, and the plate is held in place by one or more bolts 24 which pass through the jaw and screw into the inset 20. The construction enables the plate to be turned end-for-end to compensate for uneven wear and allows the plate to spread slightly in use without effecting its attachment to the jaw. Specification 537,117 is referred to.

Abstract: 489,044. Universal joints. VOIGT, C. A. Jan. 26, 1937, No. 2323. Convention date, Jan. 28, 1936. [Class 80 (ii)] Spaced parts of an intermediate member 10, Fig. 4, are associated with or form part of a rubber-metal unit, comprising two rubber blocks 7 and three metal plates 8, 5, 8, arranged alternately and adhesively secured together along flat faces perpendicular to the plane of the intermediate member 10, the inner plates 5 or outer plates 8 of alternate units being secured to the driving and driven shafts 1, 2 respectively. The driving torque subjects one half of the rubber blocks 7 to compression, the other to tension, whilst relative axial and /or radial displacement of the shafts subjects the blocks mainly to shear stress. As shown in Fig. 4, the outer plates 8 are integral with the intermediate member 10, and the inner plates 5 are integral with members 3, 4, secured to the respective shafts. In Figs. 1 and 2, the rubber-metal parts are formed as separate units, the inner plates 5 being bolted to shaft flanges 3, 4, whilst the outer plates 8 fit in radial recesses 13 in, and are attached by bolts 9 to, the intermediate member, which is formed of two axially spaced discs 10, having central holes to accommodate the nuts 12 which secure the flanges 3, 4 to their shafts 1, 2. The plates 5, 8 have oblique driving faces, and the free ends of the rubber blocks are relieved by notches. In the case of a coupling driving always in one direction the rubber blocks subjected to tensile stress may be thinner or thicker than those in compression.

Title: Process of producing lactic acid esters
IPC: C07C69/68
Filed: 1930-01-25
Abstract: An alcohol, such as butyl alcohol, is caused to interact with the lactic ester of another alcohol, such as ethyl lactate, and the alcohol displaced is removed by continuous or intermittent distillation, leaving behind the ester.  Usually, a slight excess of the alcohol is taken, and the reaction is conducted in the presence of 2-3 per cent of hydrogen chloride, sulphuric acid, or other strong acid.  The mixture is refluxed, and then the alcohol produced is slowly and carefully distilled off.  The acid catalyst is neutralized or washed out, and the desired ester distilled.  In the example the production of butyl lactate from ethyl lactate and butyl alcohol is described.  Specification 341,961 is referred to.
