Title: Improvements relating to pour depressors, wax modifying agents and the like
IPC: C07C2/68
Filed: 1941-12-24
Abstract: 557,177. Lubricating oil compositions. STANDARD OIL DEVELOPMENT CO. Dec. 24, 1941, No. 16607 Convention date, Jan. 2. [Class 91] [Also in Group IV] Condensation products which may be used as pour depressors in waxy lubricating oils or wax modifying agents are prepared by condensing an aliphatic olefin having at least 5 and less than 10 carbon atoms with an aromatic compound in presence of a Friedel-Crafts catalyst and recovering from the reaction product by distillation a fraction substantially non-volatile below about 600 F. Suitable olefins are amylenes or hexylenes or cracked gasolines containing these. The aromatic compounds are preferably polynuclear hydrocarbons, such as naphthalene, anthracene, phenanthrene, fluorene and diphenyl, but α- and #- naphthol, benzene, toluene, xylene, amyl benzene, phenol, or cresols may also be used. The catalysts may be boron fluoride, zinc chloride, ferric chloride, titanium tetrachloride, boron chloride, or anhydrous hydrogen fluoride. A solvent such as kerosene, tetrachloroethane, carbon disulphide or nitrobenzene is preferably used. An example is given of a product obtained from naphthalene and mixed, amylenes. The product lowers the pour point of a Pennsylvania type lubricating oil and can be incorporated in paraffin wax to be used for coating or impregnating paper or making moulded products.

Title: Improvements in or relating to percussive tools
IPC: B25D11/10
Filed: 1946-06-03
Abstract: 612,866. Percussive tools. STEVENS, A. H. (Wodack Electric Tool Corporation). June 3, 1946, No. 16778. [Class 124] In a percussive tool in which an impact member is retracted and released by power-actuated means and then advanced by a spring, a force-transmitting member is movable with the impact member during the latter portion of the travel thereof and engages the spring to render it operative to cushion the impact member during idle strokes. In the form shown, the tool is in the form of an attachment for use with an ordinary portable electric drill 12, the spindle of which drives a cylindrical cam 21 through the intermediary of a cup-shaped head 30. The cam coacts with a follower 26 on the impact member 13 which is prevented from rotating by a splined connection 15 with a plug 14 forming a tool-bit socket 11, the impact member being surrounded by a power spring 16. The force-transmitting member may take the form of a flanged sleeve 35 surmounted by a loose collar 37 which are so dimensioned that the follower 26 rests on the collar and the arms of the follower are held out of engagement with the surfaces of the cam when the impact member is in its normal position of rest. During idle blows the impact member is carried by inertia beyond its normal rest position, and the impact falls on the collar 37, instead of on the cam and follower arms, and is transferred through the sleeve 35 to the spring 16 after the latter has expended its power to advance the 'impact member. In another form, the collar 37 is integral with the sleeve 35, and the flange of the latter is replaced by a loose washer.

Title: Control apparatus for a warp knitting machine
IPC: D04B27/08
Filed: 1974-04-18
Abstract: 1473344 Warp knitting machines MATSUURA KIKAI SEISAKUSHO KK 18 April 1974 [26 April 1973] 17154/74 Heading D1C [Also in Division G3] A warp knitting machine has the guide bars moved by a drive mechanism controlled, for each course of the knitting by output data from a memory. The drive has an electric stepping motor or an hydraulic motor, the rotary motion being converted to linear movement by a screw coacting with a nut or a recirculating ball arrangement. The linear motion may be applied directly to the guide bar or, alternatively, a pin and drum arrangement as shown in Fig. 7 may be used. The pins 30 contact, at position P1, the fork 52 mounted on the longitudinally moved rod 51 and, at position P2, the ends 40 come into contact with the respective shogging lever. The action of cam 39 and pawls 36, 37 is to force the pin to its extended position before it is pressed into the required operating position at P1. The bridge pieces 41 are used to ensure that a smooth outer surface is provided. In a further method, Figure 11 (not shown), the shogging lever is connected by a flexible wire which passes over a pulley to the linearly moving member. The machine is stated to produce a course of stitches during 120‹ revolution of the main shaft so that 240‹ can be used for positioning the guides. The control system shown in Figure 12 includes a memory store 89 which stores information S1 about each course of the knitting. The store may be loaded either directly or through a punched card input. The main motor M drives a revolution detector 104 which causes the store to be addressed by device 90 once every revolution and the course information is extracted and stored in distributor 91. Trains of pulses are sent to the individual guide bar motors PM1-PMm in accordance with the pattern signals stored in 91 so that the guide bars are linearly moved the required amount. After a course has been knitted the control 90 addresses the store to read out the information on the next one. Ambient temperature is measured at 96 and used to adjust the number of operating pulses from the distributor 91 so that the movement of the guide bar still corresponds to a whole number of needle pitches. Backlash in the mechanism similarly is compensated for by device 100. The machine is controlled to complete a knitting course before coming to, not when the stop command is given.

[Class 12 (ii)] [See also Group XXVI] A rotary compressor for use in a refrigerating- machine is kept off load on starting until speed has been attained by arranging an adjustable spring 57 to hold the sliding abutment 40 out of action until a predetermined pressure has been established in the lubricating system. The rotor 35 is driven by an electric motor 12, the assembly including a fan 30 being supported by springs 15, 16. An extension of the rotor shaft drives a gear-wheel type pump 47, 49 which forces lubricating oil from a sump 29 through a strainer 52 into the interior of the rotor 35. A passage 56 leads oil to the back of the abutment 40 and when sufficient speed has been attained the abutment is forced into the working space against the action of the spring 57, and so puts the compressor on load. If excessive pressure is set up in the oil system a valve 61 byepasses oil to the sump. The refrigerant is circulated by the compressor through a condenser 18, a float-controlled tank 21 and evaporator pipes 23.
