Title: Smoking method
IPC: A23L27/27
Filed: 1969-01-31
Abstract: 1,208,852. Smoking food. DEVELOPMENT CONSULTANTS Inc. 31 Jan., 1969 [1 Feb., 1968], No. 5493/69. Heading A2D. Foods are smoked using liquid smoke, by atomising the liquid smoke to form a vaporous cloud, and exposing the food to this cloud without directing the spray to impinge directly on the product. During smoking, the food may be heated. The cloud may be circulated about the food or attracted thereto by electrostatic means. A suitable apparatus for carrying out the process may comprise a number of spraying nozzles arranged to direct a cloud of liquid smoke towards the food, and means for causing the droplets forming the cloud to impinge on the food. Suitable means are air circulation vents positioned above the food so that the air stream issuing therefrom will drive the droplets on to the food. Alternatively an insulated grid is provided on one or more sides of the food and adjacent to the nozzle, the food being earthed, so that when the grid is electrically charged the droplets are attached to the food electrostatically. The smoking of wieners, bacon, ham, chicken portions, fish and cheese is exemplified.

Abstract: 728,860. Endless conveyers. UNITED STATES HAT MACHINERY CORPORATION. March 2, 1953, No. 5720/53. Class 78 (1). [Also in Group VII] In a machine for felting, shrinking and crozing bats from which fur or felt hats are made (see Group VII), the bats are repeatedly-passed through the felting rollers 34, Fig. 4, by endless-belt conveyers 226, 210 and pairs of upper and lower conical rollers 310, 312, Figs. 8, 9 associated with the conveyer 226 are alternately and automatically operable to engage the flat bats 40 on the conveyer and angularly shift the bats within their own planes so that the crozing of the bats is successively effected in different directions. The conveyer 226 consists of a series of horizontally spaced endless chains which engage spaced grooves in rollers 228, 234. The bats are conveyed from the felting rollers 34 by engaging between juxtaposed portions of the conveyers 210, 226, Fig. 7, and when the bats reach the outer end of the conveyer 210 transfer rollers 262, 264, 266, 268 transfer the bats to the conveyer 226 which takes them to the felting rollers 34. One of the transfer rollers 264 is pivotally supported and is so arranged that after a predetermined time interval or after a predetermined number of bats have been crozed, control mechanism which may include a photo-electric cell operates to move the roller 264 out of contact with the other transfer rollers to function as a bat effecting means. In operation a hat bat 40, Fig. 8, tip foremost, moves towards the roller pair 312 which are in engagement while the other roller pair 310 are out of engagement and the hat bat is rotated by the pair 312 only to the position shown in Fig. 8 with its edge A forward, in which position it will pass through the crozing mechanism. On the bat's next cycle, the roller pair 312 are out of engagement and the pair 310 are in engagement, this pair 310 moving the bat 40 back to its original position tip foremost whilst on the following cycle the roller pairs are left as in the previous cycle so that the pair 310 again acts to swing the bat 40-45 degrees to bring its edge B forward. On the subsequent cycle the rollers 310 are brought out of engagement and the pair 312 into engagement to swing the bat tip foremost and the whole cycle of operations then repeated for a predetermined number of passages of the hat bat pass the photo-electric cell 298 which then operates to eject the bat. Specifications 240,513, [Group VII], and 674,479 are referred to.

Title: Improvements in or relating to electric telecommunication systems
IPC: H04M15/08
Filed: 1947-02-28
Abstract: 644,997. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Feb. 28, 1947, No. 5833. Convention date, March 2, 1946. [Class 40 (iv)] A calling line B is identified by a linefinder CE which finds an A.C. marking applied over the connection between the called line A and the calling line B. The test is made by means of an A.C. network in which the impedance between the line A and the tested line is balanced against a standard impedance EQ equivalent to a through connection. A.C. is supplied from 0 to the network over a transformer T<SP>1</SP>. The network is normally unbalanced and the output on the secondary of transformer T2 controls the anode current of a triode V1 so that the voltage across the cold cathode tube V2 is insufficient to cause excitation. When a through connection is found, the A.C. circuit is balanced, the tube V2 discharges and relay TR operates to stop the switch by disconnecting the magnet CEM. The Specification as open to inspection under Sect. 91 states that the resistance at A, corresponding to RTB, is grounded so that the finder is not stopped by the called line. This subjectmatter does not appear in the Specification as accepted.

Title: Digital-to-analogue converter arrangements
IPC: H03M1/00
Filed: 1976-02-12
Abstract: 1536863 Digital to analogue converter GENERAL ELECTRIC CO Ltd 12 Feb 1976 [12 Feb 1975] 5930/75 Heading H3H A digital to analogue converter comprises means to inject current or voltage increments into one input of an amplifier 1 and storage means selectively switchable to either the amplifier output or an input, in operation, an analogue output being built up by recirculation of the amplifier output and current/voltage injections controlled by a compression low coded input. In the embodiment using a CCITT "A" low code either source 6 or 7 is used according to the sign bit and the position within the segment built up from digits 5 to 8. Since the amplifier has a gain of 2, injections corresponding to these positions eventually have weights 8-4-2-1 giving 16 positions within each segment. This signal is then recirculated to give the final analogue according to segment indicating digits 2 and 4. In a modification to decrease the error due to noise the noise voltage increment is multiplied by 32 and after the initial phase the signal on capacitor 8 is shared with a further capacitor having 31 times its capacity (Fig. 2, not shown).

Abstract: 540,936. Photographically recording the order of passage of moving objects. DEL RICCIO, L. August 14, 1939, No. 6161/41. Divided out of 537,253 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 21, 1940. Drawings to Specification. [Classes 97 (i) and 98 (i)] A permanent visual record of the order of passage of moving objects, for example contestants in a race, across a reference line, in which the objects appear in linear spaced relation corresponding to the intervals of time between their respective crossings of the line, is produced by projecting optically the images of the objects as they respectively cross the line upon a light sensitive surface which is simultaneously moved in the same direction and at substantially the same speed as the images, the exposure area of the surface at any instant being confined to a narrow strip extending transversely to the direction of movement of the surface and including the projection of the reference line. The apparatus described for carrying out the method is that forming the subject of Specification 537,253, comprising a camera with means for running a film continuously behind a slit which limits the exposure area to a narrow strip. One edge of the slit lies on the optical axis of the objective, the camera being so set up that the image of the reference line coincides with this edge. The other edge of the slit is inclined to the first to limit the field of view to a narrow space bounded by parallel planes, one of which contains the reference line, so that the photographing of each object commences at the instant its foremost part arrives at the reference line.
