Abstract: 618,975. Combined child's seat and carrier for cycles. NIELSEN, P. I., and HANSEN, A. N. C. Sept. 26, 1946, No. 28802. Convention date,. March 11. [Class 136 (i)] In a cycle carrier adapted to form a seat for a child and embodying a collapsable back-rest and means for readily securing the carrier to the cycle frame, the back-rest is connected to the seat so that it can be swung downwards into the collapsed position against the seat and carries a pair of side arms having free front ends, the front end part of the seat being fitted with means adapted to readily detachably receive and secure relatively fixedly to the front end part of the seat, the free ends of the arm rests to maintain the back-rest in the erected position. The carrier 1 is attached to the bicycle frame by legs 2, 3 and by clamps 20, 21 on the centre bar 16. The carrier has a tiltable back-rest 4 having a pair of arms 6, 7, the free ends 8, 9 of which, when the back-rest is erect, are held in the ends of a tube under the carrier. The ends of the tube are partly cut away. The arms are released by turning the tube by means of a handle. When folded down, the part 4 is secured by a spring hook. The carrier has two spring-loaded tiltable flaps 5 and 13, of which the flap 5 forms a luggage carrier when horizontal and part of the backrest when the part 4 is erect. The flap 13 forms a horizontal carrier. Downward tilting of the flaps is limited by stays 11, 12 and 14.

IPC: D06B5/00
Filed: 1959-08-26
Abstract: In a dyeing machine of the type comprising two compartments in which the dye liquor is at different levels and connected by one or more channels containing propellers which maintain the pressure difference, a by-pass round the propeller is provided between the high and low pressure compartments and means are also provided for introducing concentrated dye solution under pressure into the by-pass the arrangement being such that the introduced solution, mixed with short-circuited liquor flowing through the by-pass is drawn through the propeller.  Fig. 1 shows one form of the invention in which one <PICT:0898874/IV (c)/1> <PICT:0898874/IV (c)/2> zone is formed by the inner tank 5 including the space 7 beneath the false bottom 6 and the other zone comprises the space 4 between the inner and outer tanks, the pressure difference being maintained by circulator propeller 9. The by-pass 10 has openings 10a and 10b into the two zones and is connected by pipe 12 to dye-bowl 11.  In a modification in which there are two channels and propellers connecting the two zones the by-pass has one opening in the middle zone midway between the two propellers and splits to form two streams travelling in opposite directions each having an outlet on the other side of one of the propellers.  Fig. 5 illustrates a mixing box for the latter modification in which p  aperture 32 connects with the middle portion of the inner zone, the concentrated dye solution enters through holes 12a in pipe 12 and the mixed dye solution and circulating liquor pass out through pipes 34.  A modification of the dyeing apparatus disclosed in Specification 883,352 is described incorporating such a by-pass.

Abstract: 1,118,305. Multiplex pulse code signalling. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. 9 July, 1965 [10 July, 1964], No. 29186/65. Heading H4L. In a time division multiplex P.C.M. system each channel of a group of l channels A, Fig. 2, is subdivided into groups B of m channels each, each channel of a group B is further subdivided into groups C of n channels each, and so on, the necessary timing pulses being supplied from a pulse generator operating at the basic repetition frequency by repeated frequency division. Transmitting equipment.-Speech signals applied at channels 1, Fig. 4, are sampled by l channel pulses applied in succession to the l sampling circuits S1, the resulting t.d.m. output being sampled at S2 by pulses at a repetition frequency lm, speech inputs being applied to the remaining sampling circuits S2 so that m samples (including the narrower sample from S1) are included in each time slot from S1. This process is repeated for samplers S3, S4, S5 and the resulting multiplexed P.A.M. signals are converted into P.C.M. by a common coder 7 for transmission. Relay stations.-Means may be provided for adding two groups of signals Figs. 6 or 7 (not shown) the groups being combined in digital form and a phase comparison effecting any necessary timing adjustment by means of an automatically controlled delay circuit affecting one of the pairs of groups. Should there be any error in timing the combination of the smaller group with the larger is prevented until the error has been corrected. Each group also has individual frame error correcting means responsive to the corresponding sync. signal. A similar group "dropping," arrangement is described, Fig. 8 a  (not-shown). Fault conditions.-An emergency switching system is described, Figs. 10, 11, 12, (not shown) in which signals are re-routed in the event of failure of normal channels. " Group recognizing digits " are transmitted which may indicate the degree of importance of each channel group so that in, the event of failure unimportant channels may be put out of service and: reallotted to important channels. The arrangement may be used in a link-by-link switching system, Figs. 9, 10 (not shown) or an end-to-end switching system, Fig. 13 (not shown).

Abstract: 1,127,664. Digital conversions. SIEMENS A.G. 30 June, 1966 [1 July, 1965], No. 29339/66. Heading G4H. [Also in Division H1] A sheet of insulating material carries incoming lines on one side and outgoing lines on the other and has apertures to hold ferromagnetic plugs to couple the incoming and outgoing lines, the plugs being U-shaped, the arms of the U forming an air-gap therebetween which is at least twice as long as it is wide and the width of which is no greater than twice the breadth of the arms. Conducting loops incorporating diodes, printed on one side of the insulating plate, constitute incoming row wires of a matrix. Conducting loops printed on the other side form outgoing column wires of the matrix. U-shaped magnetic plugs having flat closely-spaced inner faces are inserted in selected holes in the plate, each plug having one arm passing through both a row loop and a column loop, and the other arm passing through no loop (and providing a return path for the magnetic flux). A similar plate with plugs is also provided. Switches select an input row wire for receipt of a pulse which is routed by the matrices to one of the output column wires. Application to telecommunication, especially telephone, systems is mentioned.

Title: Improvements in and relating to the determination of electric discharge
Filed: 1947-11-06
Abstract: 640,188. Detecting faults. AKT.-GES. BROWN, BOVERI, & CO. Nov. 6, 1947, No. 29589. Convention date, Nov. 6, 1946. [Class 37] [Also in Group XXXIX] Faults in an oil-immersed winding, particularly when testing with surge voltage, are detected by converting pressure surges caused 'by an electric discharge in the insulating liquid into electric indicating values by electroacoustic means. The high tension winding a, Fig. 1, of a transformer is housed in an oilfilled tank b into which projects an electroacoustic apparatus c. If during a surge test there occurs a flash-over or breakdown of the winding a, an electric discharge takes place and causes pressure surges in the oil which are transformed into electric impulses by the apparatus c. These are passed through an amplifier d and indicated by an instrument e or an oscillograph. As shown in Fig. 2, the apparatus c consists of a carbon powder or crystal microphone f which is mounted outside the tank b. The membrane of the microphone closes the upper end of an insulating tube g which is inserted into the tank through the filling tube h. The lower end of the tube g, which is immersed in the oil, may be left open or closed by a membrane i, pressure surges caused by a discharge being transmitted by the column of oil in the tube and the air above it to the diaphragm of the microphone f. The tube g may be filled with gas under pressure which causes the lower membrane to assume a spherical form as shown dotted and so form a greater surface for the transmission of the pressure surges. Alternatively a condenser microphone k, Fig. 3, may be used, the oscillatory circuit k, m being tuned to the frequency of the feeding source of current n. On surges impinging on the condenser k the capacity is varied and changes the natural frequency of the circuit. This change is indicated by an instrument e after amplification in an amplifier d. Alternatively the microphone may be mounted directly on the outside of the tank. Frequency filters may be inserted in the microphone leads to eliminate disturbing frequencies.
