Title: Improvements in and relating to exhaust brakes for internal combustion engines
Inventor: SEDLACEK LOTHAR
IPC: B60K26/00
Filed: 1959-07-30
Abstract: 906,824. Controlling motor vehicles. SACHSENRING AUTOMOBILWERKE ZWICKAU VEB. July 30, 1959, No. 26170/59. Class 79(5). An engine exhaust brake is operated by movement of an accelerator pedal 2 into a retracted position considered relative to an idling position thereof and comprises a lever 3 mounted on the accelerator pedal shaft 1 and adapted to cause closing movement of a throttle 23 in the exhaust pipe 24 of the engine and shutting off a fuel supply to the engine without influencing the setting of the engine speed control on movement of the pedal 2 from the idling to the retracted position, a mechanism being provided for returning the pedal 2 to the idling position if the clutch pedal 20 is operated. The lever 3 is connected to the engine speed control by a link 4 and to the throttle 23 or to a valve 28 controlling the throttle 23 by a link 5. A dog 9 on the shaft engages an arcuate recess 10 in one face of a lever 6 which has its angular movement limited by adjustable stops 7, 8 and is engaged by a tooth 13 on a lever 14 connected to the clutch pedal 20 and urged endwise by a spring 15. When the pedal 20 is operated with the accelerator in the retracted position for engine braking, the lever 14 rotates the lever 6 and the shaft 1 which has its dog 9 engaged by one end of the recess 10 until the accelerator reaches the idling position and the lever 6 engages the stop 8. During gear changing, the tooth 13 permits the lever 14 to rotate relatively to the lever 6 while during acceleration the dog 9 traverses the recess 10. The stop 7 limits rotation of the lever 6 after it has been reengaged by the tooth 13 on upward movement of the clutch pedal 20.

Title: Improvements in or relating to yarn-winding machinery
IPC: B65H54/14
Filed: 1945-10-08
Abstract: 619,499. Winding yarn. KIMPTON, W. H. Oct. 8, 1945, No. 26174. [Classes 120(ii) and 120(iii)] An automatic spindleless pirnwinding machine adapted for winding pirns of different lengths, comprises an inner driving centre, an outer centre movable towards and awav from the inner centre so as to co-operate therewith to grip and release a pirn tube, an arm carrying the outer centre and extending substantially at rightangles to the line of centres, said arm being adjustable as a whole in a direction parallel to the line of centres to accommodate pirn tubes of different lengths, and pirn tube supplying means, adjustable for tubes of different lengths for supplying tubes in alignment with and between the centres. A constantly running shaft 21, serving a series of 10-20 spindles, drives a gear 23 freely mounted on a cam shaft 16 to which it may be clutched at 30, 32, to initiate doffing &c. The clutch, which may be of the kind set forth in Specification 475,157, is engaged by a lever 15 operated on completion of a wind to stop the pirn-driving collar 4 and the traverse 7. A cam 43 on the shaft 16 then moves the pirn and holder 5 which is supported on a spring- pressed lever 37, away from the completed pirn to release the same. The position of the end support may be adjusted in a slot 101 to accommodate different sizes of pirns, the length of the actuating chain 39 being adjusted accordingly. The released pirn falls into a chute 48. Another cam, on the shaft 16 swings a lever 50 to engage a bell-crank lever 51 on the yarn guide carriage 13 to move the same back towards the pirn driving centre 3. At the same time, a lever 60 brings the thread extending from the traverse guide 12 to a position to cross the pirn-driving collar 4. The thread is later severed by a knife 68 mounted on a vertical shaft 69. and moving between spring plates 70, 71, the motion being effected by a cam 78 on the shaft 16, the cut thread being gripped between the knife 68 and the plate 71. An empty pirn-tube from a magazine 81 is now fed between the centre 3 and the cup 5. The magazine 81, which is designed to feed tubes of a particular length, carries spring strips 82 which turn upwards at the bottom to support the empty tubes. When a different size of tube is required, the magazine is replaced by another. A shaft 84 carrying levers 85, 86 and pivoted claws 90, 91 is swung by a chain 92, operated by a cam 97 on the shaft 16, to feed the lowermost pirn tube from the magazine into position between the centre 3 and cup 5, the lever 86 being adjustable on the shaft 84. The thread is now gripped between the pirn tube and collar 4, and the cam 78 withdraws the knife 68 to free the end of thread. The cam 43 then moves the handle 15 to initiate a new wind. Specification 534,337 also is referred to.

Title: Process for treating rubber latex
IPC: C08C1/02
Filed: 1927-10-05
Abstract: 282,011. Jackson,L. Mellersh-, (Naugatuck Chemical Co.). Dec. 9, 1926, [Convention date]. Treating latex.-Concentrated latex containing alkali preservative is neutralized or slightly overneutralized to improve its plasticity and cohesiveness on the mixing mill or other machine. The neutralizing agent may be an acid, such as phosphoric or acetic, or a buffer material or salt which hydrolyzes to give an acid reaction, such as primary sodium phosphate or zinc acetate. The neutralization may be effected at any stage prior to complete drying. In one example, 100 parts of rubber in the form of 60 per cent latex containing 1 per cent ammonia is added to 22 parts carbon black and 30 parts clay in a closed mixer, and after most of the ammonia has volatilized, 1“ parts phosphoric acid is introduced and the mixture dried and milled. Vulcanizing ingredients may be added before or after the batch is dry. Compounding, acid treatment, drying and milling may all be effected on the same machine. The physical improvement of the rubber by the acid treatment is most marked when it contains a non-volatile alkali such as potassium hydroxide.

Patent GB-486641-A (GB)
Title: Improvements in or relating to rubber sheets and methods of making the same
Filed: 1937-10-01
Abstract: Porous rubber sheets suitable for bandages, garments or battery separators, are made by spraying a latex composition containing vulcanizing ingredients and non-volatile stabilizers, on to a heated deposition surface, or by spraying it alternately with a coagulant, under such conditions that a continuous layer of rubber is not formed.  The backing surface may be thin metal foil, e.g. of aluminium or a knitted or woven fabric, which may be stretched round the periphery of a hollow drum through which a heated fluid may be passed, the latex being sprayed thereon by a series of spray guns during a number of revolutions.  The sheet, with the backing, is then removed from the drum and vulcanized.  For bandages it is then cut into strips and rolled, together with the backing; the composition may include a water soluble resin, e.g. the reaction product of a polyhydric alcohol with boric acid, to render the bandage self-adherent.  Porous rubber stockings with or without a fabric backing may be formed by spraying on to an appropriately shaped former.

Title: Improvements in and relating to resin-impregnated mica paper insulation
IPC: H01B3/04
Filed: 1952-10-23
Abstract: Electric insulation is formed of micaceous sheet material, e.g mica paper impregnated and coated with a mixture of (1) an acidic polyester from glycerine and an aliphatic dicarboxylic acid having 5-10 carbon atoms, and (2) an epoxide resin formed from epihalohydrin and a polyhydric alcohol or phenol.  The resinous composition may be partially condensed and is applied to the micaceous material from solution, e.g. in acetone or in a mixture of isopropanol and toluene. The impregnated material is preferably applied in the form of tape to electrical conductors and then consolidated and thermoset by the application of heat and pressure.  The epoxy resins are of the type described in Specifications 518,057, 579,698 and marketed under the Trade Names "Epon" and "Araldite" (Registered Trade Mark).  A typical one is prepared from bis-(4-hydroxyphenyl)-2,2-propane and epichlorhydrin.  The polyesters are preferably prepared with sufficient excess of acid or anhydride to have an acid number of about 300.  Acids mentioned are adipic, glutaric, pimelic, suberic and sebacic.  Resin compositions of the type employed in the invention are described in Specification 732,253.  In a modification a cellulosic paper containing longitudinal glass fibres on its surface is impregnated, concurrently with mica paper, with the resinous solution and the two then laminated.  A number of examples are given using mixtures of various "Epon" resins with acidic glyceryl adipates.  The electrical properties of the insulations are compared.

Title: Circuit arrangement for processing and/or amplifying electrical  message signals
IPC: G06G7/19
Filed: 1973-06-05
Abstract: 1432588 Correlators NORMA MESSTECHNIK GmbH 5 June 1973 [16 June 1972] 26693/73 Heading G4A A function of an input signal is derived by using the signal as one of the parameters involved in the formation of a correlation function of an auxiliarly signal. The cross-correlation function of two time-dependent signals e 1 , e 2  is defined as and the auto-correlation function of a single signal e is given by putting e = e 1  = e 2 . The parameter t 1  is an arbitrary time delay. Figs. 1, 2; 3, 4; 8, 9 (taken in pairs) indicate the auto-correlation functions k of various kinds of auxiliary functions S of periodicity 2T 1  and it will be noted that the functions k are periodic. Fig. 10 shows one of a number of similar arrangements for forming the correlation function k using an auxiliarly signal (s) source 1, A/D converters 3a, 3b in respective parallel channels, a delay device 5 (which may be a shift register) in one channel, a correlation function generator 6 (which may be an AND gate) and, optionally, a D/A converter 7. The variation of the correlation signal with the various formation parameters A, T and t 1  are apparent from Figs. 1-9 and the invention consists essentially in varying one or more of these in accordance with an input signal u. Thus, Fig. 2 shows that variation of the delay t 1  in accordance with u such that t 1  < T 1  results in linear amplification of u. Amplification with inversion may be obtained by varying t 1  about a mean value t 1  = 1À5T, within the linear range (Fig. 3, not shown). If t 1  is varied about the value t 1  = T 1 , full wave rectification is obtained as shown in Fig. 4 and half-wave rectification may be obtained by modifying the auxiliary signal s as shown in Fig. 5 and varying t 1  about a value t 1  = (2n-1)T 1  (see Fig. 6). If the auxiliary signal is sinusoidal, the correlation function is a sinusoidal function of t 1  and, for small signals, a variable amplication factor may be obtained to realize dynamic range compression or expansion. The correlation characteristic (Fig. 9) of a sawtooth auxiliary signal (Fig. 8) may be used for measuring the r.m.s. values of periodic signals of indeterminate shape. In the above application where t 1  is the varied parameter, the input may be applied as a variation of the frequency of a clock 4 controlling one of the A/D converters which, in this case, are ergodic converters. The output of the ergodic converter 3b will be time-delayed in accordance with variations in the clock frequency. Otherwise, the input signal is applied to the shift register 5 or to both the clock and the register to obtain similar results. It is stated that the above operations may be performed in a hybrid circuit in which the A/D converter is omitted so that an analogue signal is fed to the device 6 which is, in this case, a multiplier (not fully described). The Specification also describes the use of a stochastic signal to form the autocorrelation function.
