Title: Improvements relating to gas meters, electricity meters and the like
IPC: G07F15/08
Filed: 1937-03-13
Abstract: 485,795. Prepayment mechanism for meters. ROBINSON & CO. (LIVERPOOL), Ltd., J. H., and FOX, T. March 13, 1937, No. 7404. [Class 27] In a prepayment gas meter of the kind in which the tariff can be altered after a predetermined prepayment has taken place and wherein two sets of gears operatively engageable alternatively are interposed between a meter driven shaft and the quantity mechanism, the alternative gear sets are moved into and maintained in their respective engaged and disengaged positions by positively acting means which is positively driven by the coin-released manually-operated driving mechanism of the meter. After the insertion of a coin, a handle 11, Fig. 4, is turned to rotate a ratchet wheel 12 and an internally threaded sleeve 13 engaging a screw 15 and having a collar 14 for opening the valve. The screw 15 is rotated by the meter to return the sleeve 13 and close the valve, the screw having a worm wheel 26 engaging a worm 25 driven by worm gearing from a shaft 22, Fig. 2. A shaft 16 driven by the meter has fixed to it a wheel 17 which drives a gear 21 fixed to the shaft 22 either through an idler gear 18 or, when the tariff is to be reduced, through reduction gear 19, 20. The change-over to the reduced tariff is effected positively by a cam wheel 27 having peripheral teeth 29 engaged and driven by a pin 32 projecting from an arm 33 fixed to the boss of the ratchet wheel 12, so that, at each prepayment, the cam wheel 27 is moved through one tooth. The wheel 27 has a scroll cam 28 engaged by a pin 35 on the lower end of a two-armed lever 36, on the upper end of which the gear 20 is journalled. The gear 18 is mounted on a plate 39 pivoted on the same axis as the lever 36 and connected to the lever by a pin-and-slot connection. The plate 39 has a pointed projection 42 which engages the side of a movable block 43 pivoted on the pin 35 and guided by an angular slot 45 in the block engaging a fixed pin 44. The block 43 maintains the gear 18 in mesh with the gear 21 until the pin 35 reaches the outer portion of the scroll cam whereupon the gears are changed over sharply. The cam has a displaceable cam wall portion 47 which allows the pin 35 to pass so that the cam can then be rotated without further action on the lever 36.

Filed: 1965-02-22
Abstract: 1,072,633. Plastics cups. ILLINOIS TOOL WORKS Inc. Feb. 22, 1965 [Feb. 21, 1964], No. 7554/65. Heading A4A. [Also in Division B8] A nestable plastics cup or like container consists of a bottom wall 28, an upwardly extending side wall 14 which bells outwardly to form an open mouth, a downwardly and outwardly extending skirt 22 integrally joined at the bottom wall and an annular step 16 to permit the skirt of an identical cup to rest on the step without the side walls of adjacent cups jamming together, the resilience of the skirt allowing relative axial movement of individual cups within a nested stack. The skirt 22 comprises an inner wall section 27 which is overlapped and folded back on an outer wall section 24. The bottom wall 28 is is joined integrally to the inner wall section 27 along a circumference 29, about which circumference the skirt deforms when an axial downward force is applied to the cup. The skirt 22 may be strengthened by fusing together the wall section 24, 27 along the circumference 29. Greater resistance to deformation of the skirt is provided by forming inward annular ridges in the inner wall section 27. The annular step 16 is constructed so that it is sufficiently large to ensure that the resulting small increase in the radius of the skirt 22 due to the axial force when a nested stack is compressed does not cause one cup to become jammed within another. The lower portion of the cup, which may be used for gripping purposes, consists of an outwardly convex axially resilent portion and a cylindrical portion 20 joined integrally to the other wall portion 24. The open mouth may be strengthened by forming a rolled lip 32 and a lid seat 30 spaced slightly below the mouth.

Abstract: 439,866. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. March 12, 1934, No. 7730. Void [Abridged as open to inspection under Sect. 91 of the Acts, Sept. 12, 1934]. [Class 40 (iii)] Picture signals are transmitted on one shortwave carrier and sound signals on another spaced from it by such a frequency-interval that at the receiving station a single loca oscillator can be used for producing the two subcarriers required for superheterodyne reception. The sound-receiving circuits are designed for a subcarrier of 150 kc. /sec. and the picturecurrent circuits are designed for a subcarrier of 1500 kc. /sec. The tuning of the local oscillator is varied until optimum soundreproduction is obtained ; it is then known that the sound subcarrier, and consequently the picture subcarrier, have the correct frequencies. Thus at the receiving station the common oscillator 7 is tuned to such a frequency that a subcarrier of 150 kc. /sec. is derived from the sound carrier and emerges from the rectifier 12. The sound signals are demodulated by a second rectifier 13 and amplified by a low-frequency amplifier 14. When optimum sound-reproduction is obtained the oscillator 7 is known to be correctly tuned ; and under these conditions a subcarrier whose frequency is 1500 kc. /sec. is derived from the picture-carrier and emerges from a first rectifier 8 and amplifier 9. It is demodulated by a second rectifier 10 and passed through an amplifier 11 to an oscillographic receiver 20. In a modification, Fig. 2 (not shown), the oscillator 7 may serve as first rectifier for producing one or both subcarriers, and the inductive coupling 27 may be replaced by capacitive couplings.

Title: Improvements in or relating to apparatus for tagging and tying articles
Inventor: PITKANEN ALAN RALPH
IPC: B65C7/00
Filed: 1967-02-17
Abstract: 1,129,931. Tying and tagging machine. ROYAL INDUSTRIES Inc. 17 Feb., 1967 [25 April, 1966], No. 7758/67. Headings B8C and B8P. An apparatus for tying and taging articles, e.g. sack necks, comprises means for automatically feeding and tying by twisting a predetermined length of tie around an article, means for feeding and positioning automatically a tag adjacent the tying means in order to be engaged by the tie material and tied to the article by it, and means responsive to the withdrawal of the tied article to set the automatic means for the next tagging and tying operation. Tying means, Figs. 13, 14.- A sack neck (not shown) is manually introduced into the throat 13 of the machine, displacing a control arm 84 which disengages a stop 30 from an abutment 28 to permit rotation by a one-revolution clutch of a programme plate 35. The plate comprises a feed disc 40 and as it rotates a length of tie 16 is delivered through a guide 63 and past a twister head 54 till its end reaches a point P. Concurrently, the rotary action causes an arm 104a to be disengaged'from a cam 52, the arm being moved anti-clockwise by a spring 111 to cause a wrapping finger 98 to pivot anti-clockwise to double over the tie material 16 about the sack neck and position the free end in the head 54. A segmented gear 36 on the plate 35 now engages a pinion 74 to rotate a shear blade 56 and twister head 54, thus severing tie 16 and twisting it around the sack, while guides 81 (one only shown) force the tie against the back of the head 54. The operator removes the sack and the control arm 84 resumes its starting position, causing stop 32 to re-engage abutment 28 and cease rotation of the programme plate. Means to brake the tie material supply roll is described (see Division B6). Tagging means.-The described machine may be arranged to tie only or to tag as well, by turning a knob (321), Fig. 2 (not shown). For tagging and tying, a shaft 320, Fig. 7, is so positioned by the knob that a button 307 is released and presses against a tag E lying in holding means 306b, 306c. When a tag is removed by removal of a tied sack or if none is present, button 307 will be released thus actuating switch 316, which energizes a motor which causes indexing rotation of a feed drum 303. The indexing motion is achieved by a Geneva mechanism. Fig. 4 shows how tags E are chain-fed to the throat 13 of the tying means. Each tag has an aperture E A , and the drum has pins 304 engaging the apertures in the tags which are supplied from a roll as a continuous strip. The leading tag is positioned aperture foremost so that the tie 16 passes through its aperture as it is fed towards point P, Fig. 13. A cutter, Fig. 14, see also Figs. 6, 10, 11 (not shown), severs the tags along line "X" in scissors fashion.

Direct air pressure apparatus, non - automatic. - A portable fire extinguisher of the kind wherein an extinguishing liquid such as carbon tetrachloride is expelled from a container by air pressure set up by a pump is provided with valves from the air chamber to the fluid chamber and from the fluid chamber to the discharge pipe which can be opened or closed simultaneously. The extinguisher comprises concentric cylinders 25, 26, 27, Fig. 5, forming a fluid chamber 15, an air pressure chamber 16, and a pump chamber. The pump comprises a tubular piston rod 36 having air inlets 40 and closed at the lower end by a piston head 41 with a one way valve 44. On the down stroke of the piston the air passes by a cup washer 45 to the space between the cylinder 27 and pump 36, and thence by a passage 19 controlled by a ball valve 52 and hand valve 55 to the air chamber 16. The air chamber 16 communicates with the liquid chamber 15 by means of a passage 72, Fig. 6, valve chamber 63, and passage 70 under control of a valve stem 65 slidably mounted on a bearing surface 68. Liquid passes from the chamber 15 by a tube 100 and valve bore 89 to the flexible discharge hose 22 under control of a valve disc 82 loosely mounted on a shaft 77 but held from endwise movement thereon. One end 76 of the shaft 77 is threaded to engage the stem 65, and the other end carries a handwheel 93. Rotation of the latter moves the shaft 77 and stem 65 in opposite directions simultaneously to open or close the liquid and air valves. The flexible rubber discharge pipe 22 is connected to the liquid valve by a nipple 102. A hole in the wall of the valve bore 89 and a vent passage normally closed by the cap 122 of the filling opening 120 for the chamber 15 allows the hose 22 to drain after use. The hose is retained in position when not in use by a clip on the cylinder 25. The filling opening 120 is extended as a small tube into the chamber 15 so that an air space is left above the liquid in the chamber. To prepare the device for use the chamber 15 is filled, the wheel 93 is operated to close the air and liquid valves, the pump is operated until the required pressure in the chamber 16 is obtained and the valve 55 is then screwed down to prevent air leakage.

A recording-apparatus comprises a generator of infra-red rays and means to direct a beam of the radiation on to a continuouslymoving recording surface while deflecting the beam transversely in accordance with changes in a variable to be recorded on the surface, which surface is of such nature as to change its appearance under exposure to infra red rays. Infrared rays from a source 2 are directed on to a reflector 3 whose angular position is controlled by a galvanometer 4 influenced through lines 5 by the variable to be recorded and the reflected rays play upon the wax-coated surface of a strip 1 either directly or through a reflector 6. When in use, the strip 1 is drawn from a supply spool 9 by a roller 10 driven, e.g. by a small electric motor, in a direction transverse to the oscillations of the rays which melt the wax and expose the differently-coloured surface of the strip 1 along a trace 8. The wax may be softened before recording by a device, e.g. a small electric heater or lamp 12 and to allow the wax to solidify after recording the path of the strip 1 may be extended by passing it over another roller 11. In apparatus for recording by angular co-ordinates the record surface would be given an angular movement. The apparatus is stated to be particularly suitable for electromedical purposes such as producing direct reading cardiograph records.
