Title: Improved label
IPC: G09F3/04
Filed: 1961-03-23
Abstract: 985,212. Moulding labels. R. E. CHAPMAN. June 20, 1962 [March 23, 1961], No. 10556/61. Heading B5A. [Also in Division B8] In moulding a band label (see Division B8) incorporating a legend of contrasting colour, a metal tube or former of circular section has engraved letters at spaced intervals along its length and the letters are filled with a puttylike paste including polyvinyl chloride and a black pigment. The former is then dipped into a plastisol containing polyvinyl chloride and a red pigment and then into a bath of glycerol. The product was a red tube with raised black lettering which was then cut to provide rings each having raised letters. In another method a thin strip of black P.V.C. is heat-fused to a strip or band of red P.V.C. by means of a highfrequency current heated die having the legend so that on removing the surplus black strip a red strip with a black legend remains. Specifications 965,901, 979,766 and 985,211 are referred to.

Title: Frequency band converter
IPC: H04B14/06
Filed: 1971-04-21
Abstract: 1325621 Frequency compression and expansion RAYTHEON CO 21 April 1971 [7 May 1970] 10561/71 Headings H4J and H4R [Also in Division G4] In a frequency band converter in which signals to be compressed or expanded in frequency are entered into storage at a first rate and read out at a second rate, two stores are provided, read out from one taking place while signals are being entered in the other. As described analog speech signals are converted to digital delta modulated form and groups of 400 bits are fed alternately into two 400 bit shift registers. The register currently receiving the signal is stepped at a first frequency equal to the bit frequency while the other register is stepped at half or double that frequency reading out half the previously stored group or that group and a repeat of that group. The output signals which are digital representations of the input signal at half or twice its frequency are integrated to convert to analog form. As shown the converter described above is incorporated at 65 in a diver's telephone equipment to compress voice frequencies distorted by the use of helium into the normal 5 KHZ speech band which is modulated with a 10 KHZ carrier at 66 and transmitted to the surface unit in audio frequency form. At the surface unit the received signals are demodulated at 68 and applied to an earphone or loud-speaker 71. Speech in the opposite direction employs carrier working as shown with frequency compression or expansion. The analogue to digital converter comprises (Fig. 3) a comparator 13 which gives a positive output if an input 21 exceeds a feedback 20 by a fixed amount, gives a negative output if the feedback 20 exceeds the input 21 by the fixed amount and produces no output if the input and feedback differ by less than the predetermined amount. Positive output of the comparator sets a J-K flip-flop at the next clock pulse 26 to give a positive output at 17 driving an inte-  grator. When the rising level of the feedback 20 exceeds the input by the predetermined amount the comparator gives a negative output which on the arrival of the next clock pulse resets the flip-flop. The output of the integrator drops until the comparator reverts to positive output and the cycle repeats. The resultant digital output at 18 is a "1" level pulse of duration equal to a number of clock pulse periods proportional to an input signal level separated by single period "0" level signals.

Title: Improvements in Stop Mechanism for Talking and other Sound Reproducing Machines.
IPC: G11B17/02
Filed: 1918-06-27
Abstract: 128,023. Marks, E. C. R., (Columbia Graphophone Manufacturing Co.). June 27, 1918. Periodic.-Stop mechanism for talking-machines is arranged to arrest the machine when the stylus reaches a pre-determined point during the playing of a record and also when the tone-arm is given a manual reverse movement. As shown in Fig. 1, a bent lever 12 pivoted on a pin 13 is urged by a spring 12<1> towards a position in which a brake block 11 engages and arrests a rotary disk 9. During the playing of a record, the brake is kept off by the engagement of a latch 21 with a sector 27 concentric with the tone-arm pivot and frictionally coupled to the vertical portion of the tone-arm. The latch 21 is pivoted to the lever 12 and is held by a spring with a shoulder 23 in engagement with a pin 24 on the lever 12. The sector 27 is carried by a collar 29 which is held between friction disks on the tone-arm, a, spring affording axial pressure to the disks. Thus the sector 27 normally moves with the tone-arm, but may be adjusted relative thereto by pressure applied to the knob 37, or otherwise. When the stylus reaches the end of a record, the latch falls over the edge 28' of the sector 27, and the brake 11 is applied. Moreover, a reverse movement of the tone-arm in any position causes the latch 21 to turn on its pivot, and allows the spring 12<1> to apply the brake. If desired, the sector 27 may he so adjusted that the mechanism does not operate automatically at the end of a reproduction. On the other hand the sector 27 may be adjusted so that the stop operates at any desired point by moving the tone-arm inwards until the stylus reaches the desired point. During this inward movement a pin 38 on the sector engages a fixed abutment 39 so that further movement of the tone-arm causes the sector to take up the necessary position relatively to the tone-arm. The brake is taken off by a hand-lever 14 having a spring coiled round its pivot 15 so that it springs back to the position shown when released. A shield 35 conforming in shape to the tone-arm housing may be used to stiffen the arm 29 and sector 27.

IPC: D06F37/36
Filed: 1920-04-17
Abstract: 166,679. White, A. E., (Pittsburgh Gage & Supply Co.). April 17, 1920. Reversing - gearing suitable for washing-machines is automatically operated and comprises resilient means 23, Fig. 9, for cushioning shocks. A shaft 6, Fig. 3, driven from an electric motor drives a double gear 11, which is connected through a gear 55 to an oppositely-driven gear 16. The gears 11, 16 are loose on a shaft 12 and adapted to be connected thereto in succession by a dog clutch 13 sliding between them. The shaft 12 through a pinion 17 drives a gear 18, Fig. 9. resiliently connected to the driving-shaft 20 of the washing-machine. A crank-arm 21 secured to the shaft 20 has a pin 22 encircled by a rubber ring 23 residing, in a recess in the gear 18. The clutch 13 is operated through a fork 42 and rod 39 connected to a slotted link 36, Figs. 5 and 8. A pin 29 carried by an arm 28 loose on the shaft 20 passes into the slot 37 in the link 36 and also carries a starwheel 30, having, say, six teeth. A single tooth 33 on the boss of the gear 18 engages the starwheel, so that after six revolutions of the shaft 20, a lug 31 on the star-wheel strikes a lug 32 on the arm 28, which is then carried round with the shaft 20. When the arm 28 passes through the vertical, a weight 35 upon it throws it over and completes the reversal of the gearing. The shaft 20 then turns six revolutions backwards, and so on. The slot 37 allows the automatic action to be stopped at any time. The rod 39 is connected by a pin 48 secured to it to a lever 45, Fig. 3, which swings to and fro over a plate 53, Fig. 5. When a spring pin 50 is turned to a free position, it presses against the plate 53 until it drops into a hole 55 at the middle of the stroke, and so stops the clutch 13 in neutral position. To start the machine, the pin 50 is turned to disengage it from the plate. and the arm 45 is turned to one side or the other. The shaft 56, Fig. 3, of the idler 55 may be used to drive a winger.

Title: Aromatic dipivalates
IPC: C07C69/34
Filed: 1959-03-31
Abstract: The invention comprises the dipivaloxy esters of dihydroxy-polyphenyls, dihydroxy-diphenylalkanes, and dihydroxy-polyalkylene polyphenols; and a process for the manufacture of the esters by reacting the appropriate dihydroxy compound with two equivalents of trimethylacetyl chloride, preferably in the presence of a HCI-acceptor, such as pyridine. In Example 1, 4,41-dipivaloxy biphenyl is prepared by heating a mixture of p, p1-biphenol, trimethylacetyl chloride, and pyridine on a steam-bath.  Example 2 describes the preparation of 2,2-bis (p-pivaloxy phenyl) propane. These esters are stable at high temperatures and have radiation-resistant properties; they are therefore suitable for use as coolants, hydraulic fluids, moderators, shields and lubricants in apparatus exposed to high temperatures and/or ionizing radiation (see Groups III and XL(a)).  In general the pure esters are solids; and it may be desirable to lower the meltingpoints by using mixtures of the esters.  Such mixtures are obtained by treating two or more different dihydroxy compounds of the type specified with pivalyl chloride.  The dipivalic ester of bis (p-hydroxy-b -cumyl) benzene is referred to.ALSO:The diesters formed between pivalic acid (trimethyl acetic acid) and certain dihydroxy aromatic compounds (namely dihydroxy polyphenyls, dihydroxy diphenylalkanes and dihydroxy polyalkylene polyphenyls having no more than one hydroxyl group on each phenyl radical) are used as coolants, hydraulic fluids and lubricants in apparatus exposed to high temperatures.  In general the pure esters are solids; and it may be desirable to lower the melting-points by using mixtures of the esters. Example 4 relates to the high-temperature lubricating properties of the ester derived from 4,41-dihydroxy biphenyl.
