Title: Improvements in Lubricant Testing Machine.
Inventor: LOWRY JOHN WILLIAM
IPC: G01N33/30
Filed: 1916-10-25
Abstract: 101,975. Lowry, J. W. Oct. 25, 1915, [Convention date]. Testing lubricants.-In a lubricant-testing machine, the power required to drive a lubricated member is indicated by an index connected to a power transmitting member which is responsive to the relative displacement between driving and driven members. The driven member comprises an axle 20 in a split bearing, the parts 17, 18 of which are pressed on to the axle by a pair of levers 91 and connecting-links 93, Fig. 1, the pressure being adjustable by weights 90 slidable upon the levers. Oil to be tested is placed in receptacles 25, from which it passes to the axle 20. The axle is driven by a cross-pin 35 from a disk 39, Fig. 3, to which is secured a ring 40, Fig. 4, carrying cams 51, 52, Figs. 4 and 8. A belt-driven pulley 36 carries a ring 46 provided with cams 47, 48 adapted to act in scissors-like fashion in conjunction with the cams 51, 52, to which they transmit their rotation through a member 55 provided with two pairs of rollers 61, 62 engaging with the cams. The member 55 is connected by a rod 78 with an adjustable spring 85, which resists its axial movement due to the scissors-like action of the cams; this movement, which is a measure of the power transmitted by the member 55, is shown by an index 82 carried by a spindle 80 carrying a pinion in engagement with a rack on the rod 78. A rotating index carried by a spindle 100 having worm gearing with the shaft 64 of the pulley 36, when observed in conjunction with a watch, indicates the speed of the machine. An orifice in the bearing 18 accommodates a thermometer 27.

Title: Turret lathe with reciprocating carriage
IPC: B23B3/16
Filed: 1930-05-19
Abstract: 355,245. Lathes. MAGDEBURGER WERKZEUGMASCHINENFABRIK AKT.- GES., Schwiesaustrasse, and MÍBIUS, W., 2, Schwiesaustrasse, both in Magdeburg, Germany. May 19, 1930, No. 15301. Convention date, April 24. [Class 83 (iii).] The control elements for the slides of a lathe or like machine tool are mounted in fixed positions in the bed of the machine, connection between the fixed and movable parts being effected by bevel gears mounted on oscillatable shafts. The drive for the slides may be taken from slow or highspeed shafts 6 and 7 respectively, the former driving through a wheel block 46, 47, selectively operated by dive keys, and thence through reversing gear and clutches 54, 55, Fig. 4, to spur wheels 13 and 23. The turret head 3 is longitudinally or transversely operated by a handle 15 which shifts the wheel 13 to drive either the pinion 10 engaging a rack on the slide, or a transverse shaft 16 connected to a screw 18; longitudinal movement of the drill turret is obtained by a fixed pinion 23, driven from the clutch 55, engaging a rack 24 fixed to the slide. The high-speed drive for the slides from the shaft 7 is obtained by movement of levers 22 and 30 controlling clutches and reversing gears 20 and 28 respectively. Operation of the lever 30 to effect rapid movement of the drill turret away from the headstock, Fig. 5, rotates by means of segments 31 and rod 32, a cam block 35, mounted on trunnions 34, into such position that when the turret slide reaches the end of its travel a roller 62, Fig. 5, engages the cam block and rotates the lever 39 in the direction B ; this action releases a brake 38, disengages an index pin 42 for the turret through the arm 40 striking a rod 41, and in turn sets in motion the drill turret by engaging the clutch 43. Movement of the drill turret away from the headstock is arrested by an abutment 61 on the slide striking a roller 60 on the cam block, Fig. 6, thus disengaging the clutch 59 ; rotation of the turret, however, continues until the index pin springs into its next stop position and disengages the clutch 43, bringing to rest also, the stop bar 45, at the same time an abutment 64a is released from a tongue 64, Fig. 5, which prevented the clutch 59 from being engaged for the reverse travel, on the clutch being thus engaged the turret moves towards the headstock and a roller 63 moves over the cam block, Fig. 12, (not shown), to again apply the turret brake 38.

Title: Improvements relating to electric amplifier circuit arrangements for recurring sweepwaveforms
IPC: H03K4/28
Filed: 1952-06-18
Abstract: 708,214. Saw-tooth generating circuits. EDISON SWAN ELECTRIC CO., Ltd. June 18, 1952 [June 21, 1951], No. 15386/52. Class 40 (6). [Also in Group XXXV] A saw tooth wave generator comprises a spacecharge grid valve feeding an inductive load through a transformer and the secondary winding of the transformer applies a voltage to the space charge grid which is positive during the scan to damp spurious oscillations and negative during the flyback to cut off the anode current. A saw tooth wave is applied from a blocking oscillator (not shown) to the control grid 17 of a valve 14. The output of this valve is fed through a transformer to a point 26 connected to the scanning coils of a television receiver. This point, which is positive during the scan and negative during the flyback is connected to a space charge grid 16 to increase the current during the scan and to assist in cutting off the current during the flyback. The current through a space charge grid serves to damp out oscillations initiated during the flyback and charges a capacitor 29 which may supply I-F or other valves with H.T. current. Negative feedback is also effective at the spacecharge grid since if the voltage across the scanning coils rises the space-charge grid voltage rises and collects more current causing the anode current to fall. Specification 667,521, [Group XXXV], is referred to.
Patent GB-890463-A (GB)
Title: Improved method for the separation of tantalum from niobium
IPC: C22B34/24
Filed: 1959-05-05
Abstract: Tantalum halide and niobium halide are separated by fractionally distilling a crude mixture of the anhydrous pentahalides in the absence of oxygen and moisture, to obtain a substantially pure fraction of tantalum pentahalide and a substantially pure fraction of niobium pentahalide.  The crude mixture may be obtained from an ore containing tantalum and niobium by mixing the crushed ore with carbon, heating it in a stream of chlorine or bromine, and collecting a liquid condensate. The ore may have first been fused with caustic soda and leached with water.  The crude mixture may also be obtained by halogenating a powdered tin smelter slag containing tantalum and niobium.  The crude mixture is distilled in the presence of a dry, oxygen-free inert gas, e.g. argon or helium, or chlorine or bromine. Sodium chloride or bromide may be added to the crude mixture to repress iron halide present.  A fore-run fraction is first collected, then a tantalum pentahalide fraction, then an intermediate fraction, then a niobium pentahalide fraction, and finally an after-run fraction.  When present, a tungsten halide fraction may be separated from the after-run fraction.  The intermediate fraction, and, if desired, the fore-run and after-run fractions, may be recycled to later distillations.  Examples are given.

Title: Improvements in and relating to process of making confections
IPC: A23G3/00
Filed: 1931-05-26
Abstract: Invert sugar for use in making confections containing protein, such as candies, marshmallows, coco-nut pieces, and cream centres, free from discolouration, is prepared under such conditions of acidity and temperature that the rate of the conversion of sucrose to invert sugar is fairly high, while the rate of production of decomposition products is zero or extremely low.  Thus, an organic or inorganic acid such as acetic, citric, hydrochloric, phosphoric or sulphuric acid is added to a solution of sucrose in water at 40 DEG  C., the normality of the acid being about 6/100.  The temperature is kept below 45 DEG  C. until the inversion has progressed to the desired extent.

Filed: 1944-08-22
Abstract: 581,284. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Aug. 22, 1944, No. 15985. Convention date, Oct. 21, 1943. [Class 40 (iv)] A two-way junction between an automatic office B and a manual office A terminates, at B, in a repeater which includes an amplifier 180, which is inserted (a) when the associated incoming selector 380 selects a junction to a further manual office C over level " 0 " (these junctions being also accessible over level " 5 ") or (b) when the repeater is seized by the incoming selector of one of the junctions between B and C over level " 0 " instead of the alternative level " 8." Calls from A to C. When the operator at A plugs in, line and release relays 130, 210 pull up. In addition a relay 200 is energized which operates line relay 310 of the associated selector in series with the polarized supervisory relay 220, but the latter does not operate under these conditions. When the operator dials, relay 130 repeats the impulses to relay 310 and to dialling relay 230 which shunts the line winding of relay 220 to improve the impulsing circuit and the call is extended by the selector in the usual way. The reply of the operator at C, by means of the usual current reversal, operates relay 220 which energizes relay 120 to repeat the reversal to operator A. If the junction 340 is seized over level " 0," post springs NPS operate relay 270 and the operation of relay 120 then energizes relays 140, 160 to insert the amplifier 180. The operator A can signal the operator C by intermittently releasing relay 130, the signal being repeated by the repeater 330. Operator C signals operator A by intermittent reversals of the current in the junction 340, the signals being repeated by relays 220 and 125. Calls from C to A. Selector 350 is controlled over the junction in the usual way. When it seizes the junction circuit, relay 240 pulls up and is followed by relays 120, 150, 250 and 110, the last mentioned connecting ringing generator to junction 190 which is disconnected shortly afterwards by relay 100 to terminate the signal. (Relay 100 is energized by a pulse from the generator via condenser 195 and locks up.) At the same time ring-back tone is connected by relay 150. When the operator replies relays 130, 210 and 260 pull up, the last mentioned reversing the connections of relay 240 to give the usual signal. If the junction is seized over level " 0 " instead of level " 8," relay 280 is energized in addition to the foregoing and when relay 260 pulls up it also operates relays 140 and 160 to cut in the amplifier. The operator at C can signal the operator at A by releasing relay 240 momentarily to cause a current reversal in the junction 190 by means of relay 120. The operator at A signals operator C by momentarily releasing relay 130, the signal being repeated as a current reversal by relay 260. Relay 230 is held during this operation.
