Title: Improvements in and relating to windshields for motor cars and the like
IPC: B60J1/04
Filed: 1933-01-23
Abstract: 399,062. Vehicle windscreens and window regulators. KITAMURA, Z., 264, Powell Street, Vancouver, Canada. Jan. 23, 1933, No. 2155. [Class 103 (ii).] In a motor-car or like vehicle a front glass windscreen extends in an unbroken line from the front of the car and around the sides to points intermediate the width of the doors and to afford or prevent access to the car through the doors the screen is movable longitudinally of the car by gearing operable by the driver or by the movement of one of the doors. The screen may be locked in its rear position simultaneously with the closing and locking of this door. The screen 7 is mounted in a frame 12 supported on guide rods 14, Fig. 1, and a rack 15, the rack meshing with a pinion 20, Fig. 2, connected through pinion and chain gearing to a pinion 40 engaging rack-pedals 41, 43 and 42, 44 or to equivalent mechanism controlled by the driver, such that rotation of the pinion 20 moves the screen forwards or rearwards. The right-hand door 4, Fig. 1, is also connected to the pinion 20 by means of a recessed link 49 pivotally secured to a rack 48 engaging a pinion 47 for operating the pinion 20 through mechanism including a friction clutch 26, 29. The recessed end 50 of the link 49 slides on a lip 53, Fig. 6, on the door and the recess is engaged normally by a bolt 55 vertically movable in a slide 54 fixed to the door, the slide being slotted to accommodate a pin 57 on the bolt. When the door is closed the bolt 55 seats in a hole 51 in the recess 50, as shown in Fig. 6, and the rack 48 is not in engagement with its pinion 47 so that operation of the screen by the pedals 43, 44 simply rotates the pinion 47. Opening the door 4 moves the bolt 55 to draw the link 49 rearwards bringing the rack 48 into mesh with the pinion 47 and thus moving the screen forwards. If the screen is left in a slightly forward position, opening movement of the door brings the rack 48 into mesh with the pinion 47 to move the screen to its fore. most position, and further movement of the door causes the clutch plate 29 to slip on its coacting plate 26. To lock the screen the door is opened and the bolt 55 raised from the hole 51 by the pin 57 to permit it to slide in the recess 50 so that closing the door causes the bolt first to engage the forward end of the recess and then to move the rack less than its total stroke thus leaving the rack in mesh with the pinion and thereby preventing its rotation.
Patent GB-631522-A (GB)
Title: Rich mixture motor fuel
IPC: C10L1/14
Filed: 1946-01-22
Abstract: Leaded gasolines (particularly suitable for aero engines) having an F-4 rating at least equal to that of iso-octane containing 1 ml. of tetraethyl lead per gallon, comprise a leaded base fuel having a motor method octane rating of at least 100 and boiling in the gasoline boiling range, and at least 1.0 per cent by volume in addition to any amount which may be required for the inhibition of gum formation, of one or more primary aromatic amines having the formula C6R5.NH2, wherein the R's are hydrogen and/or a methyl radical, at least one R being a methyl radical.  The amines may be toluidines or xylidines, e.g. 4-amino-1,3-dimethyl benzene or 2-amino-1,4-dimethyl benzene, or pseudo-cumidine.  By way of comparison other aromatic amines not coming within the scope of the invention, e.g. o-anisidine, benzylamine, diethylaniline and dimethylaniline, are stated to have F-4 ratings lower than S+1.  The base fuel may contain at least 1.5, suitably 2.5, ml. of tetraethyl lead per gallon.  The base fuel may be a straight-run petroleum distillate, a thermally or catalytically cracked fuel, an isoparaffinic fuel obtained by the polymerization of olefines and hydrogenation of the polymers, an isoparaffinic fuel from the alkylation of isoparaffins with olefines, an aromatic fuel, or a blend of two or more of the above types of fuel.  The preferred fuels are blended fuels such as a straight-run distillate - sulphuric acid alkylate - isopentane blend.  The base fuel may be a gasoline derived from coal or oil shale.  The leaded base fuels to which the amine is added preferably have an F-4 rating of at least S.  In general not more than 10 per cent by volume of the amine need be added.  In a series of three examples 1 per cent by volume of om- and p-toluidine respectively is added to a 100 octane aviation gasoline having an F-4 rating of S+0.7 and containing 4 ml. tetraethyl lead per gallon.  The base stock consists of 35 per cent by volume of isoparaffinic alkylate, 7 per cent by volume of isopentane and 58 per cent by volume of Midway California straight-run gasoline. Specifications 140,041, [Class 91], 385,593 and 530,597 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of aromatic amines having the formula C6R5.NHR, wherein R may be hydrogen or the methyl group, and at least one R is a methyl group, e.g. N-mono-methyl aniline, mesidene, and the N-mono-methyl derivatives of the toluidines, the xylidines, mesidine and pseudo cumidine.  Examples are furnished showing that N-ethylaniline, N - propylaniline, N - isopropylaniline and N-monobutylaniline effect little or no improvement or may even depress the F-4 rating when added to leaded gasoline, whereas the addition of N-methyl toluidines increases the F-4 rating.  The base fuel may contain no lead and its motor method octane rating may be equal to or below 100, e.g. 90. This subject-matter does not appear in the Specification as accepted.
Patent GB-383641-A (GB)
Title: Improvements relating to gas filled electric discharge tubes
IPC: H01J17/26
Filed: 1931-11-23
Abstract: 383,641. Discharge apparatus. SCHALLREUTER, W. L. W., 73, Cambridge Terrace, London. Nov. 23, 1931, No. 2163. [Class 39 (i).] Hardening or reduction of pressure in a gas-filled tube is avoided by continuously liberating the gas or vapour temporarily taken up by the material of an electrode, by continuously exposing the combination of the gas &c. with the electrode material to such a high temperature, during the operation of the tube, that the combination is split into its components. The electrode should be a metallic or non-metallic element which is not contained in the filling. In one arrangement, particles splashed from an electrode are caused to pass through a zone of high temperature to release gas &c., for example by confining the glow discharge to the inner surface of the electrode so that the highest temperature is at the centre; this arrangement is applicable when the combination is not solid, for example in a nitrogenfilled tube with carbon electrodes, the product being cyanogen ; or a chlorine-filled tube with electrodes of thallium may be used. In another arrangement, splashed particles after being deposited on another part of the electrode or on a screen surrounding the electrode are subjected to a high temperature by the discharge. The movement of the particles may be controlled by an electromagnetic field by means of an electrode or winding. In a further arrangement, the outer surface of an electrode is coated with a material such as fireclay, earthenware, or steatite, which allows the passage of gas but not of splashed particles carrying the gas. Tubes may contain two or more gases or vapours and may produce ripple and similar effects.

Title: Improvements in and relating to lubricating greases
Inventor: PARRY GEORGE ALWYN
IPC: C10M169/00
Filed: 1952-01-30
Abstract: Lubricating greases of high drop point are prepared by heating a mixture of a lubricating oil, an alkali metal or alkaline earth metal soap and an inorganic nitrite at a temperature above the temperature at which the mixture assumes a grease structure and thereafter cooling the mixture to produce a grease structure. Alternatively, an already-formed grease comprising lubricating oil and alkali metal or alkaline earth metal soap may be heated with the inorganic nitrite until it loses its grease structure and thereafter cooled to reproduce a grease structure.  According to another alternative, the inorganic nitrite may be added to a mixture of a lubricating oil and a fat, fatty oil or fatty acid and an alkali metal or alkaline earth metal saponifying agent, heat applied to effect saponification of the fatty material, and the mixture thereafter cooled to produce a grease structure.  The lubricating oil may be a mineral lubricating oil or a synthetic lubricating oil such as an ester (e.g. di-(2-ethylhexyl) sebacate) or a silicone (e.g. dimethyl silicone).  Nitrites which may be employed are those of Na, K, Li, Ca, Ba, Sr or Mg.  They may be added as such or in the form of solution or dispersion in a liquid medium such as water or an organic solvent.  Thus, they may be added in the form of a slurry in some of the lubricating oil used in the grease.  Fatty materials from which the soap may be derived are saturated or unsaturated fatty acids or substituted fatty acids (e.g. myristic, palmitic, stearic, oleic or 12-hydroxystearic acid) or mixtures thereof, animal oils and fats, vegetable oils, fats and waxes, fish oils, beeswax and degras. The metal radicle of the soap may be Na, K, Li, Ca, Ba or Sr, or the soaps employed may contain more than one metal as in the case of soda-lime greases.  Where saponification is carried out in situ, the oxide or hydroxide of the metal may be employed as saponifying agent, and the nitrite may be added before, during or after saponification.  The grease compositions may contain additional ingredients such as pour-point depressants, viscosity index improvers, anti-oxidants, anti-corrosion agents and extreme pressure agents.  Suitable anti-oxidants are phenyl alpha- or beta-naphthylamine, benzyl phenyl naphthylamine di (p-aminophenyl) phenyl methane, and p, p1- (N, N1-tetramethyl) diamino phenyl methane.  In the examples, the preparations are described of greases consisting of the following ingredients:-(a) mineral lubricating oil, sodium stearate, 12-hydroxy stearate, palmitate or myristate, and sodium nitrite, (b) mineral lubricating oil, calcium stearate and calcium nitrite, (c) mineral lubricating oil, lithium 12-hydroxy stearate and lithium nitrite, (d) mineral lubricating oil, lithium soap of hydrogenated castor oil, sodium nitrite and phenyl beta-naphthylamine and (e) dioctyl sebacate, lithium stearate and lithium nitrite.  According to the Provisional Specification, the soap employed in the lubricating grease may be an aluminium, zinc or lead soap.

Title: Improved Apparatus for Concentrating Sulphuric Acid and other Liquids.
Inventor: DURON ALPHONSE GERVAIS
IPC: C01B17/88
Filed: 1916-02-24
Abstract: 104,034. Duron, A. G. Feb. 24, 1916. Acids, concentrating; bulk evaporators; progressive evaporators.-In order to concentrate sulphuric acid and other liquids by a current of gases of high temperature without causing decomposition of the sulphuric acid, the hot gases, before they come into contact with the acid, are made to give up a part of their heat to the gases in contact with the acid. For this purpose, the gases entering by a port i are caused to flow first over and then under a partition n extending over the surface of the acid, the temperature of the gases in contact with the acid being thus kept constant by transfer of heat through the partition. By providing a number of longitudinal partitions, the acid may be made to flow in a zigzag path through a series of channels through which the hot gases flow in parallel. The gases finally flow to a recuperator a, in which the dilute acid is first treated.

Title: Improvements in devices for taking up the play in gearing
IPC: F16H25/20
Filed: 1927-02-01
Abstract: 267,094. Maag-Zahnrõder und-Maschinen Akt,.-Ges. March 3, 1926, [Convention date]. Screw-and-nut mechanism.-In means for preventing backlash in screw-and-nut gearing, for feeding a lathe slide &c., and in worm gearing, an auxiliary screw or worm member is so operated as to engage with the face of the threads or teeth opposite to that engaged by the main operating screw or worm. In the screw gear shown in Figs. 1 and 3, a nut 2 connected to a lathe slide (not shown) is operated by a main screw spindle 1 and carries an arm 4 in which turns a toothed segment 8 splined upon a shaft 10. The segment 8 gears with a segment 7 secured to a nut 5 which screws upon the spindle 1 and has an external thread of the same hand but of steeper pitch engaging an internal thread on the nut 2. The shaft 10 carries an arm 20 acted upon through a. link 18 and springs 19 by a strap 15 frictionally secured to a driving-shaft 12, the movement of an arm 16 on the strap 15 being limited by adjustable stops 21. The shaft 12 and spindle 1 are connected by a lost-motion coupling 14. Motion of the shaft 12 in either direction causes a preliminary movement of the nut 5 into engagement with the face of the threads on the nut 2 opposite to that which is engaged by the spindle 1 upon commencing its rotation, superfluous movement of the arm 16 causing compression of the springs 19 until the arm engages a stop 21, when the strap 15 slips upon its shaft. Adequate engagement between the nuts 2, 5 is maintained in spite of irregularities on the pitch of the thread on the spindle 1. In a modified construction, the nut 5 engages with the nut 2 and with a thread on a second screwed spindle driven by gearing in the reverse direction of the spindle 1. The backlash in such gearing obviates the need for the use of the coupling 14.

[Class 51 (i).] A thermostatically controlled electric motor operated damper for a stove or furnace with reduction gear incorporated in the drive, has an electromagnetic clutch interposed between the low speed shaft and the damper so that on failure of the electricity supply the damper is released and returns to its closed position. The clutch winding 13 is supplied through a rectifier 14 and a condenser 15 is connected in parallel with it when the supply 6 is alternating current. A contact 16 opened upon the damper reaching closed position, is arranged between the supply circuit and the winding and a contact 17, opened when the damper is fully opened, connects the winding in parallel with the motor. The clutch is therefore normally engaged whenever the motor is running and when the damper is open. These contacts may be operated by cams 1, 2 on the low speed shaft which also operate contacts 4, 5 in the control circuits. The system described is controlled by a thermostat in the boiler controlling contacts 9, 11 and a room thermostat controlling contacts 10, 12 ; the contacts 9, 10 are closed when cold and are in series, and the contacts 11, 12 are closed when the desired temperatures are reached and are in parallel. A three-way switch 8 provides for automatic control in its mid-position and for opening and closing the damper at will in its respective outer positions.
