Title: Writing telegraph system
IPC: G08C21/00
Filed: 1974-04-30
Abstract: 1473234 Wow and flutter correction POLAROID CORP 30 April 1974 18957/74 Heading H4R In an arrangement for reproducing on a writing telegraph, frequency modulated signals, representing movements of an original stylus, which have been recorded and reproduced with frequency errors due to the record/replay system, a reference signal having proportional frequency errors is reproduced from the record, the frequency of the reproduced reference signal is divided by the ratio of the reference signal frequency to the centre frequency of the frequency modulated signals to derive a control signal having frequency deviations equal to the error in the frequency modulated signal, and the control signal is combined with the frequency modulated signal to produce a signal in which the frequency errors are substantially reduced. As described a carrier signal fi of 3 kHz is frequency modulated with positional information in respect of the stylus of a writing telegraph to produce an information signal (fiŒ#fi) which is recorded, e.g. on magnetic tape 1, at an instantaneous tape speed N1 and is reproduced by a reproducing head 7 from the tape moving at an instantaneous tape speed N2. Also recorded with the information signal is a reference signal fr of 9 kHz. After reproduction the reference signal and the information signal, which are respective at instantaneous frequencies N2/N1 fr and N2/N1 (fiŒ#fi) are separated by filters 9 and 14 and have their delays equalized in delay devices 10 and 15. The reference signal is modulated by a fixed frequency f3, e.g. of 12 kHz. The lower sideband f3 - (N2/N1)fr is selected by filter 12 and applied to a frequency divider 13 where it is divided by a factor fr/fi and applied as a carrier to a modulator 16 which is also fed with the information signal N2/N1 (fiŒ#fi). The output of modulator 16, after filtering off one sideband, provides a signal which is applied to a further modulator 18, fed from a local oscillator LO2 with a carrier of ((f3 fi)/fr)-fi, to provide, after filtering off one sideband, a signal fiŒ(N2/N1)#fi, which is the original information signal centre frequency fi with the information signal modulation reduced by a factor N2/N1 due to wow and flutter.

Abstract: 941,919. Controlling reactors. GENERAL NUCLEAR ENGINEERING CORPORATION. May 26, 1961 [May 31, 1960], No. 19067/61. Heading G6C. The core of a reactor consists of a fixed central part 14 and outer parts 16 which can be moved laterally to control the reactor. The outer parts are carried in risers 18<SP>1</SP> pivoted at the top so that their weight tends to move the parts 16 away from part 14; actuators 26 are provided to control the movement. In the boiling water reactor shown the actuators are controlled by servo S 0  to keep steam pressure in the reactor constant. Further control is obtained by varying the proportion of feed water fed to the central part 14 through steam drum 48 and conduit 36 and to the outer parts 16 through conduit 68. A proportioning valve V-2 is positioned as a function of the position of the throttle of a steam turbine 56 or by the error between demand and reactor power. A turbine by-pass valve V-5 is connected to both control systems. Various controls are provided to maintain desired liquid levels and rates of flow. An orifice 76 produces a pressure drop which increases circulation in outer parts 16. As shown the outer parts are closed at the top and connected to an annular header, but they may alternatively be open at both ends. Specification 934, 656 is referred to.

Patent GB-192708-A (GB)
Abstract: 192,708. Stahle, G. Feb. 19, 1921, [Convention date]. Milling-screws; chucks.-A milling-machine is provided with mechanism for feeding metal rods or bars to an automatically-operated chuck mounted in an axially-movable work-holder. In Fig. 1, which shows the invention applied to the machine described in Specification 175,616, the work-holder 50 is moved forwards and rotated by mechanism including gearing 57, 58 and withdrawn after disengagement of the pinion 58 by means of a weighted cable attached to the wheel 57. Chuck jaws 82 are operated to grip the work by means of a member 84 having threaded connection with the work-holder and terminating in clutch teeth 90. A loose collar 86 on the rod 84 is connected to a long rod 88 carrying a stopmember 112. A cradle 92 provided with a screwed bushing 89 accommodates a spring- pressed clutch-member 91 and is normally held by a spring 98, Fig. 3, against an abutment 96. An inclined blank-holding table 103 extends into a recess in the cradle-member which carries a slotted blank holder 104 into which the blanks may pass when the cradle is suitably tilted. In operation, when the work-holder 50 approaches its rearmost position the tube 84 enters the bushing 89 and the clutch teeth 90, 91 are brought into engagement, thus arresting the movement of the member 84, whereupon continued movement of the work-holder screws out the member 84 and disengages the chuck jaws. During the retracting movement a plunger rod 109 controlled by a spring 115 mounted in an oil-filled cylinder is withdrawn by means of the abutment 112, thus allowing a fresh blank to drop into axial alignment with the chuck. The abutment 112 is finally tilted by a stop 114 to allow the plunger to move forward and so actuate the line of blanks to position a fresh blank in the chuck. When the driving pinion 58 is reengaged for the forward movement the cradle is tilted away from its abutment and the tube 84 is screwed inwards to close the chuck until the clutch teeth disengage. In order to regulate the braking effect on the forward movement of the plunger the cylinder 115 may be of slightly varying diameter.

IPC: A23F5/22
Filed: 1929-06-24
Abstract: 314,308. Neustadt, G., and Neustadt, I. June 22, 1928,. [Convention date]. Coffee preparations.-Extracted and decaffeinized coffee beans are enriched by a caffeine-free extract obtained in a similar manner from a larger quantity of coffee beans, or coffee substitutes in order that the extractive matter in the treated beans may correspond to the extractive content of the untreated beans. The beans are first treated with water from 60-90‹ C. and the extract withdrawn. They are then treated with wet steam, the condensate being continually removed. A thickened neutral extract is next added and the drum rotated and heated, from 60-90‹ C. The remaining extract is then withdrawn and the beans washed and dried, so that their weight corresponds to their original weight. The first extract is freed from caffeine and added to the extract residue, and concentrated ready for a second batch. A small percentage of beans may be withdrawn before the thickened extract is added, and treated with extract to form inferior coffee or coffee substitute.

Title: Improvements in weight totalisers and recorders used on automatic weighers of goods in transit
IPC: G01G23/18
Filed: 1930-06-26
Abstract: 353,652. Weight-totalizers for automatic weighing-apparatus. BROWN, S. C., 40, Gloucester Road, North Harrow, Middlesex. June 26, 1930, No. 19433. [Class 143.] Relates to a rotary numerical weight-totalizing counter and recorder operating in conjunction with an automatic weight-indicating and totalizing mechanism applied to a conveyer, telpher, hopper, track or other weigher and comprises means for exhibiting simultaneously the grand weight total with the trip weight total, the latter being provided with any type of zero resetting mechanism, means for locating and journalling the operating shaft of the zero resetting gear axially of the counter trunnions, means for indicating temporarily by the use of a hand-operated pointer or pointers either or both the aggregated plus and minus fluctuations of the weigher when rotated in an unloaded condition to test the zero setting, and means for exhibiting temporarily the total of any totalized weights, or any individual weight, by the use of a hand-operated index pointer or pointers, without interrupting the continuity of weight recording and weight totalizing. The totalizing counter, Fig. 1, is mounted on trunnions 2, 2a so that it may be swung into convenient position for reading, and is driven from the weight-totalizing mechanism by a spur-wheel 3 which actuates, by means of a shaft 4 and spur-wheels 5, 6, 7, the grand weightcounting wheels 9 and the trip total weight wheels 9a. The trip total wheels 9a may be reset by wellknown mechanism by means of a key applied to a shaft 12 coaxial with the trunnions. The dial pointer 20, Fig. 2, is mounted on the spindle 16 behind the glass face 21a. The spindle is extended through a hole in the glass face and terminates in a knob 22 carrying by means of a boss 23 a spring- depressed spindle 24 terminating at the lower end in a collar 26 and at the upper end in a knob 25. Two hand-set pointers 19, 19a are journalled in the hole through which the spindle 16 protrudes and rest upon the upper surface of the glass so that the pointers are frictionally held. To test the zero balance of the machine, the pointers 19, 19a, 20 are set to zero and the collar 26 is lowered to a position between the pointers 19, 19a as shown in Fig. 3. If the weigher is now run unloaded the maximum fluctuations of the main pointer 20 will similarly displace the pointers 19, 19a and from these plus and minus errors the mean balance of the weigher may be obtained. The collar 26 may be lifted out of operative position and retained by a pin 28. To avoid zeroizing the main pointer 20, a pointer 31 forming part of a rotatable bezel cover 32 may be provided. The two pointers 19, 19a may be used for indicating the extent of movement of the main pointer 20 between one weighing and the next; the pointers may be arranged under instead of above the glass cover 21a. One of the pointers 19, 19a may be dispensed with. The counter may embody a ticket-printing mechanism.
