In the idler circuit arrangement of Fig. 3, the parallel circuits C 1 , L 1  and C 5 , L 2  are tuned to the pump frequency and are overcritically coupled by capacitor C 3  so that a minimum of pump voltage is required. The input to the up-converter includes the circuit of Fig. 4 connected across the input terminals, the whole circuit being tuned to the signal frequency f s . The series connection of L 3 , C 4  and resistor R is tuned to the pump frequency f b  and together with capacitor C s1  forms a # circuit, the values of the components being such that the pump voltage applied to diode D 1  is 90 degrees out of phase with the voltage applied to diode D 2 . A reciprocal coupling network comprising an inductance or capacitance is connected from the output of the downconverter to the input of the up-converter neutralizes the susceptance of the converters.

Abstract: 1,054,304. Franking-machines. HASLER A.G. Sept. 26, 1963 [Oct. 23, 1962], No. 37984/63. Headings B6C and B6D. A letter 13, Fig. 2 (not shown), introduced into the machine moves a stop 16 about its pivot 16 until a control slide 20 abuts a lever 22, a pawl 29 dropping on to a shoulder 31 to release a member 33 on a locking rod 32 (Fig. 6, not shown) which is thereupon moved axially by a spring to a position which allows a rotor 26 carrying three adjustable figure-bearing discs to be rotated by a crank handle or an electric motor to print on the letter. At a certain point in the rotation, a cam 27 allows a spring 25 to swing the lever 22 about its pivot 24, causing an impression roller 23 to grip the letter between itself and the rotor, while a rail 37 on the lever 22 swings the stop 16 out of the path of the letter. After impression ramps on the rotor restore the rod and the pawl 29, the cam 27 restoring the lever 22. The rotor is thereby locked. The figure-bearing discs are adjustable by rotating rings 52, Fig. 6, when the rotor is locked. When the rotor is free, a rod 67 coupled to the locking rod is in an axial position wherein toothed wheels 53 thereon co-operating with the rings 52 are prevented from rotation by members 73, and detent rollers 62 are at the same time held in one of notches 59 by the locking rod 32. When the rotor is locked, the rollers 62 are aligned with reduced-diameter portion of the rod 32. The machine is only operable when the insertion of a key brings a stepped portion of an element 77 into alignment with the slide 20 to allow movement of the latter.

The port 80 is connected to an outlet passage 84 whereas the port 78 is connected to an outlet port 52 adjacent one end of the rotor by bores 76, 58 and a chamber 61 containing a filter 62. Surplus fluid is returned to the inlet side of the pump through a passage 66 that is controlled by a non-return valve 68. Alternatively, surplus fluid is either delivered to a point of utilization from the chamber 61 through a bore 60 that is normally closed by a plug 64 or returned to the inlet side of the pump through an external non-return valve (not shown in the drawings). The vane 24 is biased towards the member 20 by a spring 86 situated in an annular groove 90 and attached to the housing 18 by a pin 92.

A synthetic resin spinneret is made by (i) disposing a plurality of vertically extending taut synthetic filaments in a mould, (ii) pouring a thermoplastic or thermosetting synthetic resin into the mould and allowing it to set surrounding and embedding the filaments, (iii) taking the body of set resin out of the mould, and (iv) removing the filaments to leave orifices extending through the synthetic resin body. Preferably the filaments 1 are first passed tautly around and fixed to a frame structure 2, which may consist of a plurality of frame units clamped together or may be a single frame with holes to receive the filaments, and the frame structure 2 is then placed in the mould 4 which is filled with resin 5. After setting, the block of resin is removed from the mould, the frame structure 2 is cut away, the end surfaces of the block (perpendicular to the filaments) are polished, and the filaments are removed by dissolving in a solvent, by heating and melting, by applying ultrasonic vibrations, or a combination of such methods. In a modification, the frame structure 2 is separable into upper and lower parts, the filaments first being passed tautly around the frame in the mould, and resin is poured in not higher than the junction of the two parts and allowed to set first. The upper frame part is then raised to stretch the filaments above the first resin layer and the mould is filled. The resin block is then treated as above, and has orifices as shown in Fig. 3. Preferred resins are epoxy and polyester thermosetting resins, when the filaments used are nylon and polyethylene respectively, The synthetic resin spinneret has low thermal conductivity (10<SP>-3</SP> cal. cm.<SP>-1</SP> sec.<SP>-1</SP> ‹C.<SP>-1</SP>).
