Title: Equipments for the remote control and reading of the amount of displacement of a slide
IPC: B23Q17/22
Filed: 1961-04-10
Abstract: 949,648. Machine-tool details. HENSOLDT & SOHNE, OPTISCHE WERKE A.G. April 10, 1961 [May 5, 1960], No. 12765/61. Heading B3B. Means for the remote control and reading of the amount of displacement of a slide 2 wherein the displacement is read off a measuring scale 3 by a device 1 comprises at least one further reading device 50 connected by electrical means to the device next to the scale so that the values indicated by the first device are transmitted to the other. Two images of a point M on the scale are produced by a light source 5, lenses 6, 7, prisms 8, 11 and lenses 12, 13, 16. The images are reproduced by photo-electric cells 17, 17<SP>1</SP> as bands 19, 19<SP>1 </SP>on a tube 18, the currents in the cells being alternating due to a shutter 9 which is moved periodically to interrupt light from the source 5. When the point M is exactly on the axis of a lens 10, the lengths of the bands 19, 19<SP>1</SP> are equal. To adjust the lengths of the bands, a slide 20 carrying the prisms 8, 11 is moved by a screw 21. Rotation of the screw rotates 1/1000 ths. and 1/100 ths. scales 29, 22 and moves a mm.-reading scalepointer 24. An image of the point M is also projected on to a scale-reading window 31. The reading shown in Fig. 1 is 192.411 mm. as indicated in the windows 31, 25, 23, 30. The screw 21 is rotated by a motor 40 controlled by forward and reverse buttons 43, 44. The scale reading is repeated at the remote position 50 by counting mechanisms 51, 52 driven by means 71, 72 from the motor 40 and by means 81, 82 driven by a rack-and-pinion 4, 80. The mechanisms 51, 52 are associated with duplicate motor-operating buttons 43<SP>1</SP>, 44<SP>1</SP> and a valve 18<SP>1</SP> repeating the indications of the valve 18. Actuation of buttons 43<SP>1</SP>, 44<SP>1</SP> renders the buttons 43, 44 inoperative. In a modification, both reading devices are mechanical counting devices. A button is provided to operate an electromagnetic clutch to permit the counters to be set to zero.

Title: Improvements in and relating to the production of dextrose hydrate
IPC: C13K1/10
Filed: 1938-04-28
Abstract: 514,182. Glucose. INTERNATIONAL PATENTS DEVELOPMENT CO. April 28, 1938, No. 12768. Convention date, May 14, 1937. [Class 127] [Also in Group III] Dextrose hydrate of high purity is produced from converted starch solutions by crystallizing and centrifuging an impure sugar and then, without washing, remelting, recrystallizing, centrifuging and washing. Preferably the converted starch solution is given a partial clarification with spent bone char before the first crystallization. As shown, starch is converted in the vessel 1. After filtration it is passed through spent bone char clarifier 2 and concentrated in vacuum pan 3 to about 30‹ BÚ, and then in vacuum pan 4 to about 40‹ BÚ, after a further treatment, if desired, in spent bone char clarifier 2a. It is then run into crystallizer 5, together with " greens " from the final centrifuge 22 and " foots " composed of a mixture of converted liquor from 3 and solid dextrose from centrifuge 15. After crystallization, the mass is spun in centrifuge 6. The sugar is melted in tank 7, clarified in vessel 19, concentrated in pan 20, crystallized in vessel 21 and spun and washed in centrifuge 22 to give dextrose hydrate and " greens " which after concentration in pan 25 are mixed with the liquor entering crystallizer 5. The mother liquor from centrifuge 6 is acidified and diluted in vessel 8 and fed to a converter 11 where further conversion takes place as by the methods of Specifications 290,847, 303,142, [both in Class 127], or 489,937. It is neutralized in vessel 12, concentrated in vacuum pan 13, crystallized in vessel 14 and centrifuged at 15, the mother liquid being discharged at 16 and the sugar being mixed in vessel 17 with converter liquor as described above. Specification 232,160, [Class 127], also is referred to.

Title: Automatic regulator for automobile clock or the like
IPC: G04B18/02
Filed: 1965-03-25
Abstract: 1,031,330. Clocks. GENERALE TIME CORPORATION. March 25, 1965 [April 29, 1964], No. 12777/65. Heading G3T. In a clock, particularly for automobiles, a hand setting knob 49 operates means for simultaneously regulating a spring balance. As shown, and in Figs 3 to 7 (not shown), a mainspring 22 wound by a motor 20 drives the minute shaft 42 through pinion 40 engaging a frictionally mounted wheel 41. The hour wheel 47 is driven through a train 44, 45, 46. Input shaft 21 is geared through a train 23-26 to an escapement 27, 28 controlled by the balance 30, 32. On pulling out knob 49, a pinion 67 engages wheel 44 to enable the hands to be set by rotation of the knob. Wheel 44 and pinion 46 are fast with a first clutch member 51 of a clutch 50, this assembly being movable axially by a resilient arm 69 on hand setting spindle 66. A record clutch member 52 is fast with a pinion 57 engaging a toothed sector 61 which rotates a curb 63 for the balance spring 30 to regulate the balance. Between the two clutch members is a rotatably mounted shift member 53 having serrations on opposite sides to engage corresponding serrations on the clutch members. Between the shift member 53 and the first clutch member 51 there is a stationary support 71 forming a rectilinear guide for a diametrally movable slide 82, 83 which has a lug 88 engageable in one or the other of two angularly spaced notches 86, 87 formed in an arm 53c of the shift member 53. Normally the shift member is biased to a central position with respect to the support 21 by a spring 76, the slide 82, 83 in the corresponding position being biased in that lug 88 abuts a surface 85 between the notches 86, 87. Thus on pulling out the knob and rotating it, clutch members 51, 52 are engaged through the shift member 53 which moves only through a limited angle in either direction until locked by lug 88 in notch 86 or 87. Further rotation of the knob causes the clutch to slip so that regulation is limited to a precise amount and corresponds with setting the hands back or forward. Further regulation is prevented until a cam 93 on the hour shaft engages a follower 92 on the slide 82, 83 and releases the shift member for return to mid position.

IPC: B60G11/27
Filed: 1958-04-22
Abstract: 913,984. Fluid-pressure servomotor-control systems. DOWTY ROTOL Ltd. April 22, 1959 [April 22, 1958], No. 12793/58. Class 135. [Also in Group XXXII] In a pneumatic suspension system for vehicles in which air or other gas is supplied to or exhausted from a pneumatic spring of telescopic construction or a flexible bag to maintain the vehicle at a predetermined height above the road wheels the pneumatic spring is connected at 22 to a valve which is mounted on the frame of the vehicle and carries a shaft 46 on which is mounted an arm linked to the road wheels whereby any deviation of height from the predetermined value causes turning of the shaft 46 to operate a cam (not shown) which deflects a flexible strip 42 relative to a pair of orifices 38, 39 to vary the pressures on either side of a flexible diaphragm 26, or a piston, bellows, &c., which actuates ball valves 18, 19, the valve 18 controlling the supply of gas under pressure from an inlet 16 to the connection 22 and the valve 19 controlling the escape of gas from the connection 22 to an outlet 23. The supply of gas to the orifices 38, 39 is through restrictions (not shown) and the connections to the two sides of the diaphragm 26 are taken from points between the restrictions and the orifices. The relationship between the sizes of the orifices and the volume on either side of the diaphragm 26 is such that the system will not respond to oscillations at a frequency corresponding to or higher than that of natural oscillation of the vehicle on the suspension. If necessary, additional volume chambers may be connected to the spaces at either side of the diaphragm 26. To cause the system to operate only at a certain time, such as when the vehicle brakes are applied or when passenger doors are opened, the conduit supplying gas under pressure to the orifices 38, 39 may contain a valve which is opened only when it is required that the system be operative. Upstream of this valve is provided a reservoir into which gas is supplied through a restriction whereby the levelling operation can take place for a limited period only depending upon the capacity of the reservoir.

Abstract: 310,881. Andrieux, P. J. J., (Assignee of Soc. Generale des Chaux et Ciments). May 2, 1928, [Convention date], Pulverulent-fuel and atmospheric gas and vapour burners.-A burner for the combustion of a mixture pulverized, liquid, or gaseous fuel and a fluid supporting combustion comprises a hollow body or tube traversed by the mixture an elongated core arranged within and extending beyond the body or tube and defining therein an annular channel of decreasing cross section, the length of the core being many times its diameter and the mixture being delivered in the form of a hollow sheath. The portion of the core extending beyond the body or tube is surrounded by a tube providing an annular passage through which air is induced by the fuel mixture. Fig. 1 shows a burner in which a mixture of powdered fuel and primary air delivered by a blower from a pipe 1 to a conduit 3 passes through an annular passage between an outer casing 4, 5, 6 and an inner cone 7, 8 to an annular discharge nozzle formed between an outer casing 10 and the core 8. The part 4 of the outer casing and the part 6 of the inner core are both tapered outwardly, the parts 5, 8 are of uniform diameter, while the part 6 tapers inwardly, so that on the fuel mixture reaching the outlet from the part 6 its velocity has reached a maximum and, owing to the ejector action produced, additional air will be drawn in at the tapered end 12 of the casing 10. The end 12 may be adjustable so that the amount of additional air drawn in mav be varied. The core 7, 8 may be made hollow and additional air may be supplied to it through a pipe 13. The burner therefore discharges, as shown in Fig. 4, a layer of fuel mixed with air enclosing an air jet 14 and surrounded by an annular air stream 16, an ellipsoidal flame being produced in which the strongest combustion occurs at the outer surface. The additional air currents 14, 16 may be heated bv contact with hot material being cooled in a cold part of the furnace or by separate heating means. In the revolving furnace 17, Fig. 4, such as used in the cement and metallurgical industries, the additional air 16 is heated by passing from the conduit 21 over the material cooling in the region m - - n of the furnace. The joint between the pipe 1 and conduit 3 is formed with inclined surfaces 2 so as to allow of angular adjustment of the burner.
