Title: Improvements in or relating to electric connector arrangements
IPC: H01R9/26
Filed: 1962-12-05
Abstract: 1,010,636. Two-part couplings; couplings. M. HARTING, [trading as WILHELM HARTING WERK FUR ELEKTROTECHNIK UND MECHANIK]. Dec. 5, 1962 [Dec. 21, 1961; April 26, 1962], No. 45902/62. Heading H2E. Mating pairs of contacts, which may be plugs and sockets, or hybrid type, are held in engagement by mounting them in a common rack which retains them against axial separation when forces tend to pull them apart. Plugs 6 and sockets 6<SP>1</SP>, crimped or soldered to leads 5, 5<SP>1</SP> and mounted while plugged together in a resilient insulating rack (Fig. 1), have enlarged parts which engage in regions 3 and 3<SP>1</SP> of rack recesses 2 to prevent axial separation. An insulating cover 7 fits on rack 1, and notches 10 and depressions 10<SP>1</SP> are provided on rack 1 and cover 7 respectively to facilitate breaking the rack into required lengths. The rack recesses may be deep enough to hold two pairs of contacts (Fig. 8) which are electrically and mechanically connected at both sides by resilient clips 13, or by double clips 14 used to interconnect parallel recesses. A modified type of clip in two parts is also described (Fig. 12, not shown). The engaged contacts 6, 6<SP>1</SP> may be sheathed in insulating sleeves before being placed in recesses 2, the sleeves being cut-away where resilient clips are used. A different type of rack, of metal or plastic, is used where contact elements 23, 27 are mounted in resilient insulating bodies 21, 26 (Fig. 13). The bodies 21, 26 have grooves 32, 32<SP>1</SP> which fit into recesses 35 in the two limbs of a U-shaped metal retaining rack 34 (Fig. 16). In an alternative construction (Figs. 17 to 20, not shown), the insulating sleeves of the contact elements are identical, having projecting front portions which overlap to form a closed cylinder. Each projecting portion has a groove which registers with the corresponding groove in the mating portion to form one continuous groove which fits into a recess in a single-limb retaining rack which thus holds the sleeves together.

Title: Machine for making net
IPC: D04C3/06
Filed: 1970-10-02
Abstract: 1332491 Braiding machines AUGUST HERZOG MASCHINENFABRIK 2 Oct 1970 [3 Oct 1969] 46898/70 Heading D1C A braiding machine which comprises a plurality of braiding heads, each consisting of four harndogs and producing a braid, arranged in an arc includes switches for diverting bobbin supports from one head to an adjacent 'head to interconnect the braids, and a take-up with guides engaging the interconnections. The machine, Figure 1, comprises a plurality of units 4 see e.g. Figure 11, bearing several heads e.g. three arranged in an arc around a central drive 1. Take up rollers 13 are mounted on a gantry above the braiding point and the guides 34.  Each braiding head, see Figure 11, comprises four harndogs arranged below a track 23 in the shape of two adjacent 'figures of 8'. While each head is producing a separate braid, control points, or switches, 32 between adjacent heads, are set in the position shown. When braids are to be interconnected by transferring bobbin supports the points are moved to the right, or rotated see Figure 11', so that the cross-over tracks are operative. The tracks are re-switched where the braids have been joined. The points are slid across by a forked lever (68, Figure 12, not shown) engaging a pin by means of linkage from a rotatable tracked cam, (64, Figure 13, not shown) at the dictates of a punched tape. The control, Figure 25, comprises a spring- urged reading needle 49 for sensing a punched tape, and carrying a pawl 51 which in the absence of a hole, rotates a roller 52. Pins on the roller trip switches to govern the control points and guides 34. Two sets of alternately operative guides 34 to engage the intersections and push them towards the braiding point are provided and controlled from units 9, 10 respectively. Each guide consists of lever 34, see Figure 16, carrying a pin 98 and mounted on a carriage 86 sliding on a rail 94. The lower guides are pivoted into an operative position and the carriage slid along its rail by a linkage 79-85 operated by a rotatable cam drum 78. The upper guides are similarly operated in synchronism. The bobbin supports, see Figures 21, 22, comprise a hollow rod on which the bobbin 42 is mounted and in which a spring 36 is housed. The top of the spring is fixed to a head 47 carying a guide eye, while the lower end is attached by a flat spring 38 to an eccentric 41 fixed to a disc 39. The head is also connected to the disc via a member 40. If the thread runs out the disc is permitted to rotate so that a pin 44 strikes a lever 45. The tension on a spring 43 encircling a friction disc 46 on which the bobbin is carried is therefore relieved. Thread separators 100, see Figure 26, are also provided and are driven by an endless chain engaging the sprockets 104. Cams 106 are thereby rotated to move the calipers 107.

Abstract: 1506768 Ultrasonic beam direction control FURUNO ELECTRIC CO Ltd 26 Nov 1975 [13 Jan 1975] 48610/75 Heading GIG In an ultrasonic beam transmitting system, equally spaced transducers 24A-E in a row are activated at their common resonance frequency with a common but controllable phase relation between neighbouring transducers to produce a beam of controllable direction. As claimed the system comprises a row of equally spaced transducers 24A-E, a first clockpulse generator 20 for generating a first train of pulses of a frequency which is a multiple of the common resonance frequency of the transducers, and frequency dividers 18A-E driving each transducer, and a second clockpulse generator 2, 4, 6, the dividers 18A-E being sequentially initiated by sequential pulses derived from the second clockpulse generator. As described, pulses from a second clockpulse generator 2, 4, 6 are fed to a shift register 8 having the same number of BITs as there are transducers. The gate generator 16 primes the register 8 by a single pulse of duration t 1  emitted by flip-flop 12 whereafter pulses of duration t 1  (e 1-5 , Fig. 2,) (not shown) are emittedsequentially at outputs 8A-E at intervals of t 1 . These pulses sequentially trigger dividers 18A-E (which produce the transducer resonant frequency) such that there is a phase or time lag tibetween the output of any divider and its neighbour. A subsequent gate generator pulse passes the divider pulses to the corresponding transducers for the duration of the gate pulse. Beam Guidance. The time interval t 1  is controlled by a number N fed to the back-counter 4 (which outputs a pulse when N is reduced to zero) such that NE o =t 1  where to is the period of the third clock pulse generator 2. For given operating conditions to is selected so that N represents the value of the beam angle in degrees. The numerical input unit 6 can vary N so that the direction of the beam can be altered.
