Abstract: 455,720. Endless - belt conveyers. COUCH, F. J., 216, Brooks Avenue, Rochester, New York, U.S.A. June 21, 1935, No. 17892. [Class 78 (i)] [See also Groups VIII and XVI] An apparatus for stacking towels A and other articles of flat work coming from an ironing-machine 5 comprises endless conveyer bands 54 on to which the articles drop as they come from the machine and from which they drop as the conveyer starts its return lap. The conveyer is surrounded by a series of rollers 44 which are rotatably mounted in endless side chains so that the roller beneath the turning point of the conveyer intercepts the falling article and draws one end thereof forwardly whereby the article is laid on top of the pile accumulating on a table 62. The conveyer bands are arranged to be driven faster than the side chains of the rollers so that they will tend to draw the towels &c. off the rollers as they come from the ironing- machine. The rollers are rotated on their own axes for a portion of their passage over the top lap of the conveyer by the frictional engagement of their ends with the angle irons of the side frames. The central portions of such irons are omitted and the side chains alone are supported at such points so that the rollers are free to rotate under the weight of any towels &c., still remaining thereon.

Abstract: 855,576. Transistor amplifier circuits. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd., and BRITISH TELECOMMUNICATIONS RESEARCH Ltd. May 22, 1959 [June 6, 1958], No. 18087/58. Class 40(6). The Figure shows a buffer amplifier circuit for connecting at least one signal source to at least one output circuit, the signal source having two voltage conditions represented by -6 volts (the on condition) and 0 volts (the off condition) and exemplified by the voltage of the collector of transistor TX3 of a bistable trigger circuit. (not shown). In the off condition the junction of resitors R1 and R2 is at earth potential due to diode D1 conducting the base of transistor TX1 is thus at approximately 1 volt above earth so that the transistor is non-conductive. In the on condition the junction of resistors R1, R2 is at - 6 volts so that transistor TX1 is conductive but places no load on the signal source represented by transistor TX3. Since the driving current for transistor TX1 varies in dependence upon the number of stages, such as transistor TX2, to be fed from its collector circuit the value of resistor R2 is varied in dependence upon the number of stages. With a given number of stages TX2, current is fed into resistor R2 from + 24 volt supply over resistor R3 and from the emitter of transistor TX1 which is its conductive condition and this may make the junction of resistors R1, R2 positive with respect to the - 6 volt supply. Diode D1 blocks this condition from the collector of transistor TX3 i.e. from the signal source. Stage TX2 is similar to stage TX1 but a single value of resistor R5 caters for a variety of loads in the collector circuit of TX2 and this value of resistor R5 will not cause the on condition to make the junction of resistors R4, R5 positive in respect to - 6 volts so that diode D1 is not required. The clamp D2 and resistor R5 although part of the collector circuit of TX1 are shown as part of the base circuit of TX2 so that when the components are separately mounted, for example with printed circuits, if TX1, TX2 become separated TX1 is not damaged by excessive collector voltage from resistor R5 since the collector circuit is broken. TX2 is similarly protected against excessive collector volts if the - 6 volt supply fails when TX2 is cut off by the provision of resistor R7. Clamp D5 protects further against supply failure if both the - 6 and the + 24 volt supply fail the collector of TX2 is protected since the voltage at the junction of D7 and R9 is such that D6 is backed off.

Title: Improvements in or relating to the preparation of novolak resins
IPC: C08G8/28
Filed: 1946-06-18
Abstract: To prepare a phenol-formaldehyde novolak resin, one mol. of a phenol is reacted with not more than 0.9 mol. of formaldehyde in presence of an alkaline catalyst until substantially all the formaldehyde has combined, the reaction mixture is acidified with sufficient acid to prevent formation of a rubbery resin upon subsequent dehydration and the mixture is then dehydrated.  Any phenol having at least two free reaction positions may be employed.  The proportion of pehnol employed in the initial alkaline reaction may be greater than that specified in which case extra phenol is added to adjust the balance either before or during the acidification.  The initial reaction may be at room or elevated temperature.  It should be terminated when all the formaldehyde has combined.  Condensation may be continued after acidification, particularly if the amount of acid added does not greatly exceed the necessary minimum.  Suitable alkaline catalysts are alkaline hydroxides or carbonates or organic bases, e.g. dimethylamine or piperidine.  The products may be rinsed with hexamethylenetetramine and fillers to form moulding powders.  In the examples: (1) phenol and formaldehyde are condensed in the presence of sodium hydroxide and hydrochloric acid added; (2) cresol-formaldehyde condensate catalysed with caustic soda and then hydrochloric acid; (3) p - tert. - amyl - phenolformaldehyde condensate formed in the presence of caustic soda and sulphuric acid; (4) phenol and formaldehyde condensed with caustic soda, phenol added, followed by hydrochloric acid and the whole condensed further; (5) phenol and formaldehyde are condensed in presence of ammonia, and the mixture acidified with hydrochloric acid before dehydration; (6) magnesium oxide is used as the alkali and hydrochloric as the acid. Specification 159,461, [Class 2 (iii)], is referred to.

Abstract: 373,458. Pencil holders. PRINTATOR GES., 20, Lehderstrasse, Weissensee, and HAHN, H., 8, Olberstrasse, Charlottenburg, both near Berlin. June 24, 1931, No. 18302. [Class 146 (iii).] In a pencil holder of the type having a spring-controlled lead-. guide tube adapted to slide relatively to the outer tube and projecting beyond the forward and rear edge of the outer tube, the forward end being of double conical formation externally and split longitudinally so that when in the retracted position the projecting end coacts with the front end of the outer tube to grip the lead, the guide tube is held in retracted position by a spring acting between a shoulder on the guide tube and on the conical portion of the inner wall of the outer tube, and the guide tube is moved forward by means of a cap fixed on the rear end of the guide tube. The guide tube comprises a front portion c for the lead b, and a rear tubular portion d having a sliding fit in the outer tube a and constituting a spare-lead magazine e. A plug f, into which the front end of the guide-tube c is screwed, is secured in the rear end of the rear portion d and is provided with a flange g which serves to centralize a spiral spring h disposed between the end of the plug f and the inner wall of the tapered portion a<1> of the outer tube a.

Patent GB-532520-A (GB)
Title: Improvements in or relating to knitting machines
IPC: D04B35/00
Filed: 1939-06-23
Abstract: 532,520. Knitting-machines. TOONE, H. B. S., TOONE, H. S., (trading as TOONE & CO., B.), and COLE, B. T. June 23, 1939, No. 18330. [Class 74 (ii)] A circular machine having a cutter for severing a yarn withdrawn from knitting is provided with means for regulating the length of the loose end of the yarn that projects from the fabric at the point of introduction or at the point of introduction and at the point of withdrawal. The invention is described in connection with a seamless hose machine having splicing mechanism and, in addition to a main cutter and trapper 52, an auxiliary cutter 29, 30 for the splicing yarn. The splicing yarn S is fed to the needles by a guide 10 under control similar to that employed on Scott and Williams machines, and on an arm 16 pivoted about the same axis 14 as the guide 10 a yarn-tensioning device 19 is provided. The arm 16 is operated from the guide 10, an adjustable screw 17 carried by the arm resting upon a pin 18 projecting from the guide, and the lowermost position of the arm is determined by a second adjustable screw 20 engaging the feeder bracket 15. Thus, when the splicing guide 10 is lowered into feeding position, the arm 16 and the tensioning device 19 carried by it are brought to rest before the guide reaches its feeding position so that the tensioning device draws back the loose end of the yarn through the guide 10. The extent of this draw-back, which is regulated by adjusting the screws 17, 20, determines the length of the loose end of the thread projecting from the fabric at the commencement of a splicing course. The movable blade 30 of the cutter is operated by a lever 61 overlying an adjustable tappet screw 28 carried by the arm 16. When the guide 10 is raised, the arm 16 is lifted, and after a lag determined by the adjustment of the screw 28 the lever 61 is actuated to operate the blade 30. The lag between the withdrawal of the splicing yarn and the operation of the blade determines the distance between the cutter and the last splicing needle at the point of severance, and so regulates the length of the loose yarn projecting from the fabric at the withdrawal of the yarn. A tapper may be associated with the cutter 29, 30 and may comprise a blunt knife blade in advance of the blade 30. In a modification, the lever arm 61 is dispensed with, and the tappet screw 28 engages directly with an arm carrying the cutter blade 30. The lever 61 may support a bent wire member 63 so disposed that when the lever is actuated the wire enters between the two discs forming the yarn tensioning device 19 to release the friction on the splicing yarn to prevent the loose end of the yarn acquiring undue twist such as would cause it to fly about when cut. Alternatively, or in addition, the yarn may be guided after it has left the guide 10 by the slotted end 66<SP>1</SP> of a lever 66 arranged within the needle circle. Specification 532,586 is referred to.
Patent GB-979701-A (GB)
Title: Skew correction buffer
IPC: G11B20/12
Filed: 1963-05-09
Abstract: 979, 701. Magnetic tape stores. SPERRY RAND CORPORATION. May 9, 1963 [May 22, 196; No. 18331/63. Heading G4C. In an arrangement for deskewing data read from a multi-channel magnetic tape, the data is translated to serial form before application to a deskewing circuit comprising a plurality of buffer registers, the number of such registers depending only on the maximum possible amount of skew which can be expected. The arrangement describe relates to a magnetic tape 1 having data arranged as shown in Fig. 2 in nine channels 0-8, each 9-bit work being called a "frame" of data. A data record consists of a 28-frame start pattern followed by an arbitrary number of data frames followed by a 28-frame stop pattern. The data when read from the tape appears in a skewed manner as shown in Fig. 3, where the third bit of channel 0 is read before the first bit of channel 8 (i.e. there is a skew of three frames). The nominal time interva between consecutive bits of any channel is 10 Ás, the bits read out being stored temporarily in flipflops (not shown) in a READ AND SYNC circuit, Fig. 1, the flip-flops being cyclically and continuously sensed every 4 Ás by a clock pulse train consisting of machine cycles 4 us in duration and having nine timing pulses t 0 -t 8  corresponding to the nine data channels. Each time a clock pulse senses a clock pulse senses a new bit in its corresponding flip-flop, this bit is read out to an INFORMATION line and together with a pulse on a SPROCKET line, transmitted to the deskewing circuit 3 which thus receives serial data comprising the bits of different frames interlaced in a manner dependent on the amount of skew. Deskewing circuit, Figs. 5A, 5B. The deskewing circuit 3, Fig. 1, is shown in more detail in Figs. 5A,5B and comprises four "frame registers" FROFR3 each capable of storing nine bits in a recirculatory manner, the registers FR1-FR3 being each connected to the input of the next lower register, the deskewed output being obtained serially from the register FRO and supplied to a utilization circuit. If more than four frames of skew are detected, an OVERSKEW signal is produced to alert the utilization circuit. When data frames are being read the registers FR0-FR3 collect data bits belonging to the same frame and when the register FR0 is filled with a complete 9-bit frame, this is shifted to the utilization circuit and the frames FR1-FR3 are shifted up. The "start pattern" bits in each channel include three "sentinel" bits 011 in the 26-28th positions, which bits are employed to preset the frame registers FR0-FR3 to receive the data appropriately. The elements employed in the circuit 3 include "negative OR" or "negative AND" gates marked with a "+" or "o" respectively, which gates are logically identical and produce a positive output only when all inputs are negative. An ordinary AND gate is marked "F" and the circuit includes also pulse formers PF which have an inherent one-pulse delay, and 7-bit delays marked "#".
