Title: System for sorting postal documents or letters

IPC: B07C3/00
Filed: 1965-06-14
Abstract: 1,111,061. Sorting machines. DE STAAT DER NEDERLANDEN, TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR-GENERAAL DER POSTERIJEN TELEGRAFIE EN TELEFONIE. 14 June, 1965 [26 June, 1964], No. 24967/65. Heading G4M. In a letter-sorting machine, the transport path is divided into equal sections, and the entry of a letter into each section is detected by respective photo-cells #1-#8 and #1.1-#1.8 to #8.1-#8.8, Fig. 1, which control the advance of sort-control signals through a pair of shift registers a, b so as to operate deflectors at the appropriate times. Register b controls the main path deflectors k1-k7 and register a controls the branch path deflectors k1.1-k8.8. Each stage S1b-S7b of register b controls the associated deflector through a decoding logic circuit, whereas each stage, escept S1a of register a controls a pair of branch path deflectors such as k1.1, k1.2 through respective decoding circuits, Fig. 5 (not shown). After passing read-station l, a letter, which is to be sorted into the third compartment of the second branch path, covers f thereby causing the sort-control signals binary " 2 " and binary " 3 " to be entered in stages S1b, S1a respectively. The decoding circuit associated with S1b can only produce an output in response to binary " 1," k1 is not actuated and the letter proceeds to the next main path section. When #2 is covered, the sort-control signals are advanced to S2b, S2a and k2 is actuated by the decoding circuit associated with S2b. The next photo-cell covered by the letter is #2.1 which advances the sort control signal to S3b, S3a. Neither k2.1 nor k2.2 is actuated and the letter proceeds to #2.2 which advances the sort-control signals to S4b, S4a, the decoding circuit associated with S4a then actuating k2.3. Any letters which are not directed to a compartment are fed on to return path r. Logic circuits are also illustrated in Fig. 5 for indicating malfunction of the machine. If a letter which should have been deflected e.g. by k2.1 or k2.2 subsequently covers #2.2, a lamp is lit to indicate incorrect operation at junction k2.1, k2.2. Conversely, if the letter should have passed k2.1, k2.2 but does not subsequently cover #2.2 the same lamp is also lit (indicating a jam).

Abstract: 1,022,882. Electric control systems. CINCINNATI MILLING MACHINE CO. June 24, 1963 [Nov. 29, 1962], No. 24986/63. Heading G1N. The error signal in a closed loop servo system for positioning a controlled member is limited to a predetermined level so that the controlled member moves at a constant speed over a long range of movement between two points. The desired position of a machine tool slide 10 is set in position store 16, and position analogue unit 20, which employs resolvers, generates an error signal dependent in amplitude on the distance between the actual and desired positions of the slide. The amplified error signal is applied to a detector 30 which gives a D.C. output. The signal is then fed to limiter 36 which gives an output having a maximum amplitude determined by the voltage applied at 40, 42. A rate signal is added at 46 and the resulting signal is applied to compensating network 56, which is an RC network or integrator circuit comprising a D.C. amplifier, to raise the low frequency response of the rate feedback loop. The amplified signal then operates a hydraulic motor 12 driving slide 10. The limiter 36 comprises a diode bridge 66, 67, 68, 69, (Fig. 5, not shown) the input being applied at 34 and the output appearing at 38. A A.C. from source 82 is rectified and smoothed, and is applied to leads 40, 42 to define the limit to which the circuit is set, which is adjustable by slider 84.

Title: Method of product control in aqueous suspension polvmerizations of alkenyl aromatic compounds
IPC: C08F2/18
Filed: 1959-07-24
Abstract: An alkenyl aromatic compound is polymerized in an aqueous medium containing 0,023 to 0,4% of a salt of a sulphonated polyvinyl toluene, until from 8 to 60% of monomer is polymerized and before agglomeration occurs, and then an anionic or nonionic surface active agent is added and polymerization continued to give a non-sticky granular product.  Optionally 0,5 to 0,01% of a divinyl aromatic compound may be present.  The presence of neopentane, pentane, hexane, heptane, iso-octane, or dichlorodifluoromethane gives products which expand to a cellular mass on heating.  Polymerization is accelerated by the use of a peroxygen catalyst or mixtures thereof and in examples other ingredients used are potassium dichromate, ammonium sulphate, sodium sulphate, and ammonium or sodium hydroxide for adjusting pH to 6.ALSO:Products which can be foamed on heating, e.g. by steam, are obtained by polymerizing an alkenyl aromatic compound in an aqueous medium containing 2 to 25% based on the monomers of neopentane, pentane, hexane, heptane, iso-octane, dichlordifluoromethane or dichlorodifluoromethane, and also containing 0,023 to 0,4% of a salt of a sulphonated polyvinyl toluene, the polymerization being carried out until from 8 to 60% of monomer is polymerized and before agglomeration occurs, and then polymerization being continued in the presence of an anionic or nonionic surface active agent whereby a non-sticky granular product is obtained.  Optionally 0,5 to 0,01% of a divinyl aromatic compound is present and polymerization is accelerated by the use of peroxygen catalysts.  In examples the monomers used are styrene, ethylvinylbenzene and divinyl benzene, and the pH of the media used are adjusted to 6.

Title: Improvements in or relating to binary information transmission systems
IPC: H04L27/233
Filed: 1963-06-27
Abstract: 1,030,194. Data transmission. SIEMENS & HALSKE A.G. June 27, 1963 [June 28, 1962], No. 25549/63. Heading H4P. The invention provides a binary data transmission system in which, from a series of data bits, are selected groups of n bits, each group commencing with the first mark bit to occur after the end of the preceding group. Each group is characterized in transmission by one of 2<SP>(n-1)</SP> " characterizing signals." Any space bit which is not included in one of the selected groups, e.g. the final S in a series MSS when n = 2, is represented by no change of characterizing signal from that previously transmitted. The arrangement permits increased input and output data bit rates without increasing the transmission rate. Phase-shift transmission is employed. In one arrangement of the transmitter in which n = 2, Fig. 1 (not shown), binary data feeds a logic circuit which provides a pulse whenever there occurs a 2-bit group starting with a mark bit. These pulses, together with the input data, are fed to a 3-stage reversible counter. The group MS causes stepping of the counter in one direction, and the group MM stepping in the other. The counter output controls the phase of a carrier, which is thus shifted to one of three phases, the direction of the shift relative to the previously received phase indicating the group being transmitted. No change in phase indicates the presence of an ungrouped space pulse. At the receiver, Fig. 3 (not shown), the phaseshifted signals are limited and passed to modulators both direct and via a delay and phase shifters. The modulator outputs, after processing to reduce the effect of parasitic pulses, are respectively stretched to 1 and 2-bit lengths. By summing these stretched signals the original data is reproduced. Because the rate of change of phase corresponds to the frequency change relative to a constant carrier frequency, a receiver as in Fig. 7 (not shown), may be employed. Here the received signals, after limiting, pass to a frequency discriminator which provides a pulse of polarity dependent on the direction of change of frequency (and hence of phase). These pulses are separated to positive and negative channels and act on a pulse-stretching arrangement similar to that described for Fig. 2 to reproduce the original data.
