Title: Improvements in shoulder box machinery
IPC: B31B7/00
Filed: 1958-08-14
Abstract: 838,385. Making boxes. SCHWARZ, L. Aug. 14, 1958, No. 26135/58. Class 18. In making a shoulder box, i.e. a box having an insert 3, Fig. 1, standing up above the box walls 2, the walls are bent over the base before assembly of the box to increase the flexibility of the sides and to cause them to adhere to the insert 3 more readily. The blanks are cut from a roll of stout paper or cardboard by a press or a rotary tool and fed either to a hopper or directly to a first conveyer 17. Helical ramps 19 bend up two opposed walls 2 of each blank and fingers 21 turn the walls back again. The blanks then pass to a second conveyer 18 where ramps 20 turn up the remaining opposed sides and similar fingers 22 return these sides to their original position. Alternatively, the conveyers may be in line and means provided for turning each blank through a right angle. The punching of the blanks can be stopped if the assembly of the boxes is stopped. Top rails 23 retain the central portion of each blank. The inserts 3 may be supplied from a shoot 8, pass through wheels 9, be supplied with adhesive by wheels 9a pass through a device 10 which dries the adhesive to a tacky condition and then is opened by suction pads 11, 12. Subsequently, a plunger forces the insert and the blank through a die thereby folding up the walls 2 into contact with the insert.

Title: Rotation sensor
IPC: G01P3/36
Filed: 1966-06-13
Abstract: 1,102,827. Lasers. VABIAN ASSOCIATES. 13 June, 1966 [21 June, 1965], No. 26193/66. Heading H1C. The circulated radiation in a ring laser used for rotation sensing is frequency-modulated to prevent locking of the two counter-circulating frequencies #, #<SP>1</SP> at very low rates of rotation. As shown in Fig. 1, a c.w. gas laser 10 is located in a closed loop path formed by mirrors 12a- 12d, the path including an acoustic modulator 14 such as a quartz crystal or rutile which is powered by a signal generator 16 at a microwave frequency #s. The modulator diffracts the counter-circulating frequency modes #, #<SP>1</SP> into a second closed loop path formed by mirrors 18a-18d, the modulated frequencies in this path being #+ #s and #<SP>1</SP> - #s respectively. The frequency difference, viz. 2#s+ #- #<SP>1</SP>), is detected by a photo-detector 22 after the modulated frequencies are extracted from the second loop by a partially-transmitting mirror 18b and are reflected by respective mirrors 20, 24. The detected frequency is then combined with a reference frequency 2#s obtained by doubling the modulating frequency #8 in a multiplier 26, a mixer 28 providing the difference output # - #<SP>1</SP> due to rotation of the laser. In an alternative arrangement, the ring laser comprises two separate laser devices 30, 32 located in a closed loop path formed by reflecting mirrors 34, 36, 38 and a semi-transparent mirror 40, an optical shutter 42 being located midway between the two laser devices. The shutter is operated at a frequency which is a multiple of the mode spacing and may consist of a crystal energized from a generator 44 so as to support an acoustic standing wave. Only short pulses of radiation are able to circulate in the closed loop, and since during rotation these pulses of counter circulating radiation arrive at the two laser devices at different times then mutual reaction and locking is avoided. A modified arrangement uses two optical shutters, Fig. 3 (not shown). In a further embodiment, Fig. 4 (not shown), a a ring laser of basic form has an electro-optic modulator crystal, e.g. of KDP, in the closed radiation path, this crystal being energized so as to modulate the circulating radiation.

Title: Improvements in or relating to loading gate assemblies suitable for the control of the discharge of fluent materials
Inventor: GRIESELHUBER WILLIAM
IPC: F16K3/18
Filed: 1956-08-28
Abstract: 846,386. Valves. WESTERN STATES MACHINE CO. Aug. 28, 1956, No. 26310/56. Class 135. A gate valve for opening and closing a discharge spout 10, Fig. 1, from which, e.g. a mixture of sugar crystals and syrup is discharged into a centrifugal separator, comprises a body 11 secured to the spout having a seating facing 16, a closure member 15 connected to a crosshead 17, Fig. 2, for movement therewith, by the engagement of bolts 19 in sockets 20 in the closure member and an inflatable bag 46 to which high-pressure fluid is admitted through a pipe 49 to urge the closure member into sealing engagement with the facing 16 when the valve is closed and to which lowpressure fluid is admitted at all other times to permit ease of movement of the crosshead and closure plate over the facing 16. The crosshead 17 which is connected to the body 11 for movement relative thereto by slide plates and bolts (not shown) is formed with parallel bores into each of which is clamped a cylinder 35, co-operable with a fixed piston 37. On movement of a control valve 60, Fig. 5, to its full-line position, high-pressure fluid is directed through pipes 65, 44 to the lower ends of the cylinders and exhausted from their upper ends through pipes 43, 66 to move the cylinders downwardly to close the valve. When the valve reaches its closed position the spring-loaded plunger of a valve 52 secured to the crosshead engages an adjustable stop 59, to move the plunger upwardly to interconnect lines 57, 56 so that high-pressure fluid is directed into the bag 46 to urge the closure member sealingly against the facing 16. On movement of the control valve 60 from its full-line position to its chain-dotted position to open the valve, the lower ends of the cylinders 35 and the bag 46 are momentarily connected to exhaust through a port 67 to reduce the pressure before the top ends of the cylinders are connected to pressure fluid and their bottom ends to exhaust. After the gate has been raised a short distance the spring acts on the plunger of the valve 52 to connect the bag 46 to pressure fluid reduced in pressure by passage through a pressure-reducing valve 68. Clearance between the bolts 19 and sockets 20 permits slight further downward movement of the crosshead 17 after inflation of the bag 46. In a modification, the inflatable bag 46 may be replaced by a rigid member flanged around its periphery and engaging the closure member, a flexible diaphragm sealingly clamped against the flanged periphery and a backing plate disposed between the diaphragm and the crosshead.

Title: Method of producing tone films
IPC: G03B31/00
Filed: 1930-09-04
Abstract: 368,689. Recording sound. JELINEK, S., 43, Alserstrasse, Vienna. Sept. 4, 1930, No. 26360. Convention date, Sept. 6, 1929. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] A series of sounds recorded at different times and in different places is combined into a single sound record so that the sounds may be simultaneously reproduced. The actions relating to these separate sounds may also be photographed and combined, in known manner, so that a single complete talking-picture film is produced. According to the invention, the sounds originally recorded are converted into the corresponding current variations which are caused to influence the galvanometer of the studio sound-recording apparatus which is also effected by the sounds produced by the actors &c. during the enactment of the scene in the studio. Thus a sound record is produced which contains, in their appropriate blending, the series of sounds which were originally recorded separately. The action in the studio is also superposed on the scene previously photographed so that a combined talking-picture film is produced which when reproduced conveys the impression that the whole of the sounds and action were simultaneously recorded. The relative strengths of the various series of sounds united in the final sound record may be varied at will. In an alternative method, the separate sound records are mechanically united in their correct relationship and run through the soundreproducing apparatus simultaneously so that the reproducing photo-electric cell is influenced by the light passing through each of the record tracks. The invention may be applied to the recording of a talking-picture film in different languages. Specification 347,625 is referred to.

Title: An indicating circuit, particularly for digital data storage apparatus
IPC: H03K17/62
Filed: 1964-06-25
Abstract: 1,038,539. Semi-conductor pulse circuits. BUNKER-RAMO CORPORATION. June 25, 1964 [July 18, 1963], No. 26388/64. Heading H3T. [Also in Division G4] In apparatus for determining the lowest one in order of a plurality of terminals arranged in a predetermined order that is supplied with a signal, each terminal is fed via a variable conductance device (such as a transistor) to a different tapping point in a series chain of diodes connected across a current source so that the variable conductance device corresponding to the first signal-carrying terminal becomes conductive, diverging current from the diode chain. Fig. 1 shows apparatus for extracting data from a content addressable data store (associative store). The store output is available on terminals 10 1  ... 10 N  which are connected to respective bi-stable circuits each comprising a reciprocally coupled pair of transistors Q1, Q2. In the absence of signals on any terminal 10 1  ... 10 N , the NPN transistor Q1 will be off, turning on the NPN transistor Q2 and turning on the PNP transistor Q4 so as to divert the standing current normally flowing via resistor 14 and diodes D 1  ... D N , through the resistor R5 appropriate to the lowest order terminal not carrying a signal. A signal will thus be fed on the appropriate line 16 1  ... 16 N  to an encoder 17. Advance pulses from 12 are fed to transistors Q3 of each stage so as to reset the bi-stable circuit in which transistor Q4 is conductive. This action turns on the transistor Q4 of the next stage having no input signal, so that the output line 16 1  ... 16 N  receives a signal. Capacitors C1 prevent the resetting of two stages by the same advance pulse. Each diode D 1  ... D N  has a threshold voltage of 0À6 v., hence the maximum number of terminals which can be monitored by this circuit is of the order of 16. Fig. 3 shows an arrangement in which a large plurality of terminals are monitored by circuits subdivided into segments 1 ... P. Each terminal (not shown) is coupled to a bi-stable circuit FF comprising transistors Q1 ... Q3, as shown in Fig. 1, controlling transistors Q4 which divert current from tapping points on respective diode chains. The diode chains corresponding to segments 2 ... P are supplied with current via emitter followers Q7 only in the event of none of the stages of the previous segment carrying signal. Diodes 36, 38 are provided for this purpose. In Fig. 2 (not shown) the base/emitter path of a further transistor is included in series with the lower diode of each segment, the collector voltage of said further transistor being fed to the base of the appropriate transistor Q7.
