Abstract: 1366574 Electrostatic precipitators POLYSIUS AG 29 March 1972 [11 June 1971] 14659/72 Heading B2J The exhaust gases from a furnace 1, e.g. a rotary cement kiln, are cleaned in an electrostatic precipitator and are brought to a desired temperature, e.g. 400‹C to 420‹C, for this purpose by suitably controlling both the flow of the gases 11 from the furnace and the flow of raw material 8, e.g. ground cement, to the furnace through a pre-heater. As shown, the preheater has three stages 3, 4, 5, stages 3 and 4 being by-passed by a path 10 for the raw material 8 and by a path 16 for the gases 11. Thus part of the flow of raw material, and/or part of the flow of exhaust gases may be diverted from the preheater so that the gases have the required temperature when they reach the precipitator 6, this control being effected in dependence upon the degree of cleaning in the precipitator. Should the exhaust gases be used for grind-drying in a mill 7, the by-passes 10 and 16 are closed so that the gases are not overcooled.

Title: Improvements in or relating to quality control methods for meat processing
Inventor: HAYWOOD LESLIE HERBERT
IPC: G01N23/08
Filed: 1966-04-04
Abstract: 1,077,868. Photo-electric meat testing. SAUNDERS ROE & NUCLEAR ENTERPRISES Ltd. April 4, 1966, No.14944/66. Heading G1A The fat to lean meat ratio of a meat product, e.g. sausage meat, is tested by passing γ- radiation from a promethium-147 bremsstrahlung source through the product and obtaining a count of the radiation transmitted, this count being compared with that obtained, using a standard filter of a material other than the product, and equivalent to an acceptable fat to lean meat ratio for the product. The apparatus used comprises a holder 7, for the source 8 (promethium with an aluminium or zirconium target) mounted on a turn-table 3 within shielding 2. The sample 16 can be moved to locate it underneath the detector, a Geiger-Muller chamber 18, whose pulse output is counted by a counter 22, controlled by count selector 23, timer 24, start control 25 and reset 26. The standard filter is of aluminium, for example, and its thickness is decided by comparing the count time obtained with filters of different thicknesses with the count time obtained using a predetermined quantity of meat of satisfactory fat to lean meat ratio. In this calibration, five counts were taken for the sample each filter and the average times compared. An unknown sample of sausage meat can thus be tested by comparison with this standard filter, the quantity of meat used being the same as that used in the calibration. If the difference in the counts is outside the permissible circuits, the fat to lean ratio is unsatisfactory. The method relies on the high absorption by lean meat over that by fat due to differences in the atomic numbers of the elements contained therein, and so the presence of other ingredients in the meat may decrease the sensitivity of the method.

Patent GB-149800-A (GB)
Abstract: 149,800. Relay Automatic Telephone Co., Bryant, G. H., Johnson, B. B., and Ward, F. M. May 30, 1919. Automatic exchange systems.-In systems in which the connecting-means, such as relays, are controlled by initial energizing-circuits picked out by an impulse-responder, a group of lines, such as to a private branch exchange, has a common initial circuit and also individual initial circuits for each line. A subscriber calling a number corresponding to the group of lines A, B, C, Fig. J, energizes the common initial circuit 1, 4, 7, which' extends over the front contacts of the relays F of busy lines to the line relay of the first idle line of the group, to which connexion is made, or a busy signal, is given, as described in Specification 11600/15, if all the lines are engaged. On the other hand a subscriber may call a number representing an individual line of the group, and in that case energizes the corresponding initial circuit 11, 12 or 13, and either makes connexion to that line or gets a busy signal. The connecting system may be of the kind described in Specifications 9840/14, 105,363, and 109,380. The relays CO are the cut-off relays and F the fault relays of the various lines. A fault relay is energized whenever the corresponding cut-off relay is energized, and also when the line is faulty, as described in Specification 112,650. If one of the lines is faulty and the other lines of the group are busy, a call on the common circuit 1, 4, 7 is taken over a special signal circuit 14 through front contacts of the three relays F and a back contact of the relay CO of the faulty line. In the modification shown in Fig. III, a call to an individual faulty line (say A) is taken to the signal circuit 15.

[Also in Division G1] The speed of a vehicle over a predetermined distance is measured by recording constant frequency pulses on a track driven at a speed proportional to the vehicle speed, subsequently driving the track at a constant speed in playback apparatus, measuring the intervals between successive pairs of pulses, and continuously displaying the results of repeated measurements. Fig. 9 shows part of the playback apparatus, in which a timer TG supplies pulses through an AND-gate UZ to a counter ZK. Pulses J from the pick-up head trigger a monostable multivibrator M3 to close the AND-gate for a time t3. Simultaneously evaluation device AE (digital printer or curve recorder) is put into operation to record the number in counter ZK. When M3 reverts to its initial state the counter is reset and gate UZ is opened. The measured value differs from the interval between a pair of pulses J by t3, a known constant. Instead of resetting counter ZK to zero it may be reset to a number corresponding to the time t3 so that the numerical result is directly equivalent to the pulse spacing. In a modification AND-gate UZ and multivibrator M3 are omitted. When a pulse J arrives the value stored in ZK is transferred to AE and ZK is simultaneously reset. Arrangements are also described in which a capacitor is charged at a constant rate during a pulse-interval and the charge at the end of the interval is measured (see Division G1).
