Title: Treatment of oil palm fruit
IPC: A23N5/00
Filed: 1974-10-14
Abstract: 1463565 Treating oil palm fruit GUTHRIE CORP Ltd 14 Oct 1975 [14 Oct 1974] 44465/74 Headings A2E, A2D Fruit bunches of the oil palm Elaeis guineensis Jacq., and/or the oil palm Elaeis oleifera (HBK) are exposed to a gaseous mixture of air and an unsaturated hydrocarbon to loosen the fruit from the bunch. Hydrocarbons specified include acetylene, ethylene, propylene and butylene. Treatment is carried out for at least 5 minutes at room temperature, preferably higher, using a gaseous mixture containing at least 0.01% hydrocarbon. Superatmospheric or subatmospheric pressure to cause the hydrocarbon gas to enter the tissues of the bunch may allow shorter treatment times or lower hydrocarbon concentrations to be used. The contentration of carbon dioxide in the treating gas may be reduced by means of an absorbent such as NaOH, this also shortening the treatment time. Heating during or after the treatment will also accelerate the action of the hydrocarbon and sterilize the enzyme system to prevent the build up of free fatty acids.

Title: Improvements in or relating to radio and like receiver installations
IPC: H04B7/08
Filed: 1964-11-05
Abstract: 1,028,084. Relaying system; radio receiving circuits. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT. Nov. 5, 1964 [Nov. 7, 1963], No. 45124/64. Headings H3Q and H4L. In a radio system, comprising two identical automatic gain-controlled receiver channels, continuously operating in parallel, loss of amplification in an early stage 3 of one channel normally causes the automatic gain control 15 of that channel to increase the gain of the later stages 7 until the output signal level is restored. The noise level at the output of the early stage is however also over amplified, such that the signal to noise ratio at the radio output 13 is much worsened. The invention overcomes this fault by coupling together corresponding early low-power points A and B, by means of a cable 14 whose electrical length l is a whole multiple of the wavelength # of the signal at the coupled points. By this means failure of an early stage 3 in a channel causes power to be transferred to that channel, from the other channel, by means of the cable, without any alteration in phase. The automatic gain control of the defective channel is therefore no longer caused to over-increase the amplification of the later stage. The invention is described as applied to a television relay station, wherein signals are received at 1, frequency changed in stages 4 and 8 and retransmitted at 13.

Abstract: 1,048,416. Television. BRITISH BROADCASTING CORPORATION. Dec. 6, 1963 [Dec. 6, 1962], No. 46148/62. Heading H4F. A pulse h (Fig. 2) termed a " guide " pulse, and comprising the first line synchronizing pulse (after differentiation in 14, Fig. 1, not shown) occurring at the end of the field synchronizing period of a television waveform is gated out by the arrangement of Fig. 1 from the waveforms of both local and remote video sources and, by phase comparison of the two pulses utilized to enable the field synchronization of the latter source to be brought to within one line of synchronization (with the local source) after which exact synchronism is effected by known "genlocking." Fig. 3 (not shown) depicts one way in which near synchronization may be effected by employing the local guide pulses from selector 17 (e.g. embodying the arrangement of Fig. 1) to open a 90 microsecond gate 20 through which the remote guide pulses from selector 18 pass only when both guide pulses are within one line of correct phase. The local video is then mixed with the passed guide pulses in 22 and fed to the main simultaneous broadcast network the signal from which, if available at the remote station, is utilized to enable the field phase control of the latter station to be adjusted to bring the guide pulse on to the selected line of its waveform so that genlocking then effects exact synchronization. If the network signal is not available at the remote station the guide pulses may be transmitted to the latter over a telephone line as pulses of a 1000 c.p.s. signal so that a steady tone indicates correct phase. The remote guide pulses and the output of the pulse generator 19 controlling gate 20 may be combined in mixer 21 and the output displayed on local picture and waveform monitors to provide information as to the relative phases of the two signals.

Abstract: 1,036,887. Photographic processing apparatus. AGFA A. G. Dec.28, 1962 [Dec.29, 1961], No. 46777/61. Heading G2A. A photographic processing apparatus has an endless flexible band which circulates through the apparatus, part of its path being outside said apparatus so that the photographic material may be attached at that point; the said material normally passes from a light-tight enclosure directly through a light trap into the apparatus (but being brought outside for the said initial attachment). In the form shown, the photographic material is conveyed through one or more processing tanks 12 by means of an endless band 16, guided into and out of the tanks by rollers 15,14. During part of its return run, the band is brought outside an end wall 17 of the apparatus. The strip of photographic material to be processed is enclosed in a lighttight cassette 19 which is attached in a holder 31. The leading edge of the film strip 18 is drawn between two rollers 35, 36 by means of a knob operating the latter, and led into the apparatus through a narrow horizontal tunnel 21 acting as a light trap. During normal operation, the film strip then passes round a guide roller 29 and takes the path 28 leading directly to the conveyer belt 16. For initially attaching the leading edge of the film strip to the belt, the strip passes along the tunnel 21 and then continues straight along, to be guided downwards by a curved part 22a of the outer wall 22. The curved wall part 22a continues as a straight part 22b, which eventually terminates at an edge 23. At this point there is a narrow opening through which the leading edge of the film strip passes out, and can then be attached manually, as shown at the loop 25, to the moving belt 16. This leading part of the film strip will of course be fogged, and not usable. After attachment, the belt 16, moving upwards, draws the attachment point of the film back into the apparatus, and eventually the film is once more passing along its normal path 28 from cassette to tank 12, the whole of the film in the cassette now being progressively drawn into the apparatus for processing under light-tight conditions. The apparatus can be adapted for use with more than one film strip.
