Title: Improvements in condensate return apparatus for steam heating systems
IPC: F24D19/08
Filed: 1933-08-08
Abstract: 423,801. Valves. INDUSTRIAL HEATING CONTROL PROPRIETARY, Ltd., 436, Bourke Street, Melbourne, and MURRAY, E. A., 2, Zeal Street, West Brunswick, Victoria, both in Australia. Aug. 8, 1933, No. 22155. [Class 135] [See also Group XIII] Condensate from a steam heating system is returned from a sump 18 to the boiler 11 when a control valve 23 in the steam pipe 22 between the boiler and sump is opened, the pressures in the pipe 22 and the sump being then equalized. The control valve is opened by a spring 32, Fig. 3, when the pressure on a diaphragm 24 is released, and closed when the diaphragm is under pressure. In the former position of the valve, the diaphragm chamber 25 is connected to atmosphere by the opening of a relay valve 35 operated by a float 37 which rises with the level of the condensate in the sump. In the latter position of the control valve, the relay valve 35 is closed and the diaphragm chamber is under the pressure of the steam in pipe 22 through a byepass 26. A diaphragm 42 operates simultaneously with the diaphragm 24 and opens a check valve 41, controlling the steam outlet pipe 40 from the sump, when the control valve is closed. The condensate primarily collects in a closed sump 14 from which it is forced under pressure to the sump 18, a pressure reduction unit 47 being provided between the steam outlet pipe 40 and the return steam pipe 13 from the heating system. To avoid banking up of condensate in pipe 13 due to excessive pressure in the sump, the pressure is released through a pipe 56 and being greater than the steam pressure acting through a pipe 55 on the underside of a diaphragm 54, opens a break valve 51 operated by the diaphragm allowing air and steam to escape from the sump to atmosphere. In a modification, the sump 14 is replaced by an open sump, the unit 47 then being unnecessary, and the break valve is replaced by a valved connection which, when the control valve is closed, allows steam to flow to an ejector in the riser pipe 16 to cause condensate to be fed from the lower to the higher sump. In a modification, employing a single sump, after the condensate is discharged, steam from the sump byepasses to the pipe line 13 and is cooled by the condensate so rapidly that the apparatus resumes normal functioning instantaneously.

Title: Digital telemetering system
IPC: G08C19/18
Filed: 1960-06-24
Abstract: 937,522. Analogue to - - digital converters. STANDARD TELEPHONES & CABLES Ltd. June 24, 1960 [June 25, 1959], No. 22223/60. Class 40 (1). The output voltage of a transducer TR is applied to one input of a comparator comprising a Wheatstone bridge modulator MO, a variable reference voltage being applied to the other input of MO from a resistance network supplied by a counter in a converter DAC1. A train of pulses from generator GR2 is applied to MO over transformer T1 and a sinusoidal voltage whose amplitude represents the difference of the analogue and reference voltages is derived from transformer T2 and is applied to a Schmitt trigger AS. Pulses from generator GR1 are supplied to the counter in DAC1 over gate G1 until the output of MO is zero, whereupon AS changes state and triggers monostable circuit MS1 to close gate G1. The pulses supplied to DAC1 are inverted at I1 and fed to a modulator TD which transmits a train of pulses, equal in number to those supplied to DAC1, the train being terminated by the triggering of MS1. A long reset pulse is then transmitted and the counter in DAC1 is reset. At the receiver, the pulse train is supplied to a converter DAC2 through gate G2 and a corresponding analogue voltage is developed. The long reset pulse at the end of the conversion cycle is detected by a Miller integrator DC which then applies a pulse to set bi-stable circuit BS to the 1 " state, thereby applying the output voltage of DAC2 to a recorder RE through gate G5 and resetting a further converter DAC3 which is then conditioned to receive the next pulse train via gate G4. At the end of this next train, the output voltage of DAC3 is supplied to RE via gate G3 and DAC2 is reset and conditioned to receive the next pulse train over gate G2. If the output of TR is only slowly varying the system may be modified, Fig. 3 (not shown), so that a conversion only takes place when a significant change occurs. A modified form of converter is described which comprises two counters, one of which initially registers zero and each pulse supplied thereto increases the comparison voltage by nv whereas the other counter initially registers its maximum count n and each pulse supplied thereto decreases the comparison voltage by v. The output of the comparator is used to gate pulses to the counters in such a way that pulses are supplied to the first counter until the comparison voltage exceeds the analogue voltage, and then pulses are supplied to the second counter until equality' is reached. Means, not described, are provided for dif. ferentiating between the two trains of pulses transmitted.

Title: Method and apparatus for splicing cinematograph films
Inventor: CATOZZO LEO
IPC: G03D15/04
Filed: 1960-06-24
Abstract: 881,463. Kinematograph film splicers. COSTRUZIONE INCOLLATRICI RAPIDE S.a.r.l. June 24, 1960, No. 22226/60. Addition to 876,393. Class 98(2). The splicer of the parent Specification is modified by an adaption enabling it to be used with film having perforations along either both edges or one edge only. As in the parent Specification, the two ends of film to be joined are first trimmed by a subsidiary guillotine 13. They are then placed in the groove 2 of a die plate 5, where a single row of register pins 4 hold them in correct alignment. A double row of holes 3 in the die plate correspond with the film perforations. A roll 7 of adhesive tape is so mounted as to unroll across the two ends of film to be joined. Finally, as in the parent Specification, an arm 16 mounted on a pivot bolt 15 carries a pair of cutter blades 20, 20<SP>1</SP> arranged transverse to the pivot 15, to cut the tape to the length required. The arm 16 also carries a set of punches to punch out the perforations once more when they are covered by the .tape. In the present device, two rows of punches 17, 18 are provided, corresponding to the two rows of perforations, punches 17 being longer than punches 18. Also pivoted on bolt 15 is an upper die plate 22, having notches which allow passage of the punches 17, 18. On plate 22 siides a stop plate 24 having an upwardly bent tongue 24c. When this is slid fully back, the tongue 24c can enter into a slit 16a in the arm 16 when this is lowered. Thus the arm can be pressed completely into contact with die plate 22, and both sets of punches 17, 18 will penetrate the tape, forming perforations along both edges of the film. When the stop 24 is slid forward on plate 22, the tongue 24c will not enter slit 16a as the arm 16 is lowered, and will hence prevent the latter from coming into full contact with plate 22. Thus only the longcr punches 17 will penetrate the tape, so forming perforations along one edge only. The punched-out portions of tape adhere to the tongues of a pair of steel combs mounted under die plate 5 for that purpose. Specification 855,321 also is referred to.

Title: Improvements in combination locks or padlocks
IPC: E05B37/00
Filed: 1919-09-10
Abstract: 154,008. White, A. E., (Soc. Anon. pour l'Exploitation des Brevets Descalles). Sept. 10, 1919. Locks, permutation; padlocks. - In a permutation lock or padlock, the bolt or hasp is released when the combination disks are set to permit motion of a locking-lever. The combination disks are operated by rotating a single knob, which is rotated in one direction to bring all the disks into a predetermined position, and then alternately in opposite directions to set the disks in succession in the unlocking position. The combination can be changed when the lock is open. Fig. 1 shows disks 10', 11<1>, 12<1> operated by a single knob 14' and which correspond to the toothed wheels 10, 11, 12 of the padlock shown in Fig. 2 with part of the casing removed. The hasp 1 is locked by a spring-lever 3 which can only be released when its projections 7 is able to move into notches 8 in toothed wheels 5 gearing with the toothed wheels 10, 11, 12 which are provided with spring clicks 23. The wheel 11 has a deep tooth for locking engagement with its click when setting the wheels or disks in the predetermined position referred to above. In setting the disks 10<1>, 11<1>, 12<1> in this position the knob 14<1> is turned clockwise, so that a tooth 15<1> on disk 10<1> engages a long tooth 16<1> on a slide 18<1> carried by the disk 11<1>. A tooth 21<1> on the disk 11<1> engages a spring- tooth 22<1> on the disk 12<1>. When the disks approach the initial position, the tooth 22' reaches a recess in the padlock casing into which it is pushed by the bevel of the projection 21<1> which snaps past it, the disk 11<1> being then arrested by a click engaging its deep tooth. A projection 20<1> holds the slide 18<1> in the position shown so that, when the knob is turned in the opposite direction, the projection 15<1> is kept in engagement with the short tooth 17<1> of the slide 18<1> and all the disks are turned together. On now turning the knob clockwise, the disk 12<1> is left in set position and the slide 18<1> is freed from the projection 20', the disks 10<1>, 11<1> being moved together to set the disk 11'. The disk 10' can now be set without disturbing the disk 11<1>, as the projection 15<1> acts on the short tooth 17' to push up the slide 18<1> and then to pass it. The wheels 5 are mounted on a pivoted plate which can be operated from outside the padlock, when open, so as to throw the wheels 5 out of gear when it is desired to change the combination.
