Patent GB-1251404-A (GB)
IPC: B27F7/34
Filed: 1969-07-17
Abstract: 1,251,404. Stapling machine. U. MONACELLI. 17 July, 1969 [19 July, 1968], No. 36165/69. Heading B4C. A pneumatically actuated stapling machine includes an anvil 17 movable relative to a staple guide 8 by means of support members 15 slidable in guides 18 and an auxiliary piston 11, the tubular rod 12 of which is secured to the members 15. Auxiliary cylinder 9 for the piston 11 is coaxial with a cylinder 5 (in an alternative arrangement it may be parallel with cylinder 5) in which a staple driving piston 6 slides. Compressed air in reservoir 31 is permanently supplied to a chamber 30 above a differential piston type valve 27, and to a tubular rod 22 via ducts and ports (not shown). A differential piston type spring urged valve 28 controls opening and closing of chamber 30 to atmosphere via port 26<SP>1</SP>. In operation actuation of a trigger 32 moves a control rod 33 upwardly to permit compressed air to pass via passages 34 -38 into the cylinder 9 to thus raise the piston 11 and the anvil 17. When material to be stapled is clamped between the anvil and staple guide air pressure in cylinder 9 below the piston increases and, upon attaining the pressure of the air in reservoir 31, overcomes the bias of the spring 29 and air pressure on the lower surface of the valve 28 to move the valve 28 and to open chamber 30 to atmosphere. The valve 27 then rises and permits compressed air to pass into cylinder 5 for driving the piston 6. If no material or insufficient material is between the guide 8 and the anvil 17, port 25 in cylinder 9 will be exposed and the valve 28 will not be moved to open the chamber 30 to atmosphere. Upon release of the trigger after a staple driving operation the air below the piston 11 will be exhausted to atmosphere via passages 37, 38, 45 and passages not shown, and air introduced via rod 22 into chamber 20 will force the piston 11 downwardly. The valve 28 is closed due to pressure differential acting on the valve surfaces and chamber 30 is closed to atmosphere. The valve 27 is then moved downwardly by air pressure in chamber 30 and communication between the cylinder 5 and reservoir 31 is closed. The drive piston is then returned by air in chamber 47 compressed during the driving stroke. The cylinder space above the piston 6 during the return stroke via annular gap 61 and passage 45. The gap 61 is closed by valve 60 when the valve 27 is in the position of Fig. 3.

Abstract: 1,266,783. Spectroscopic cells. MERESTECHNIKAI KOZPONTI KUTATO LABORATORIUM. March 4, 1969 [March 5, 1968], No. 11552/69. Heading G2J. In an optical liquid sample cell for liquids containing gaseous and/or solid phases, the sample is subjected to centrifugal forces to cause separation of the phases which may then be examined individually. In a through flow cell, having an inlet 2, outlet 9, and radiation guides 5, 6, the sample, for example, a liquid gas mixture, is introduced tangentially through inlet 2, and the rotational flow caused concentrates, for example, gas particles at the longitudinal axis of the cell. By masking the guides, as at 7 and 8, radiation is passed only through the liquid phase. The guides 5, 6 may be respectively replaced Fig. 5 (not shown) by a disc having two transparent windows and a reflective disc. Radiation enters through one window and is reflected back through the other. In a further throughflow cell, Fig. 3, a stationary blade wheel 14 introduces the rotational flow, and by situating the radiation guides 17, 19 on the longitudinal axis of the cell the gas phase may be studied. In non throughflow cells, Figs. 5 and 6 (not shown) rotatable blade wheels drive by an external magnetic source are provided, and the radiation guides may be arranged as in the through flow cells.

Abstract: 1305359 Preventing acoustic reaction SZM GABR 20 Jan 1970 32411/72 Divided out of 1303792 Headings H4J and H4R In a loud-speaking substation including transmit and receive transducers and at least one amplifier, part of the signal in one channel (transmit or receive) is fed back through a selectively variable modifying network and combined with the signals in the other channel between the transducer and an associated amplifier to render the net signal in that channel independent of the signal in the first channel. As described, part of the output of the microphone amplifier is delayed in phase (e.g. inverted) and combined with the loud-speaker amplifier output to cancel signals reaching this amplifier from the microphone via a hybrid or via the transmission path. It is stated that cancellation could alternatively be effected at the microphone. In one form as shown, the loud-speaker has two coils 12 and 14. The coil 12 receives incoming signals from the line 19 via hybrid 18 and amplifier 16. The microphone 10 is coupled to the line via an amplifier 15 and the hybrid. The hybrid inevitably partially couples the microphone output to the loud-speaker and additional coupling may be effected via the line. The effect of this is eliminated by providing a second path via a variable attenuator 21 and a variable phase shifter located at 22, 22a or 22b to the second loud-speaker coil 14 to provide a second input in opposition to the undesired signal. In a second embodiment the loudspeaker has a single coil coupled to the secondary of a transformer having two primaries functioning like coils 12 and 14.

The silverware may be fed on to the bed 12 by hand or by means of an apparatus 14 comprising a perforated drum and a chute 20. A lower bed 30, to which the vibrator 46 is connected, is attached to the bed 12 for receiving the knives and is formed with grooves 36, Fig. 4, at the end of which are provided discharge openings 38, Fig. 1, for the knives. Funnels 40 and receptacles 44 are positioned as shown to receive the knives, spoons and forks. The recess 54 is cut into the bottom of the bed 12 beneath each opening 24 so that the handles of the spoons bear against its walls to maintain the small bowl spoons 50 in suspended relationship. The recess 54 communicates with a larger recess 56, Fig. 10, which allows the small bowl spoons to tilt and slip through the opening 24. The width of the opening 24 is however too small to permit passage of the large bowl spoons. The bed 12 is formed with a plurality of V-shaped grooves 22, Figs. 2, 4 and 10, at the bottom of which are the openings 24, 26, 28 and along which the silverware pieces travel. The use of V- shaped grooves enable forks to lie flat on the bed 12 until they reach the openings 26 so that they by-pass the openings 24 and 28. The movement of the sliverware along the bed 12 may alternatively be effected by bushes or water streams. The latter could also be used as a supplementary moving means and for rinsing the silverware.
