Title: An installation for the treatment of plants with carbonic acid gas, derived from impure gases or waste gases
IPC: A01G9/18
Filed: 1920-07-12
Abstract: 149,008. Riedel, F. Nov. 24, 1917, [Convention date]. Plants, treating with air and gases.-Carbonic acid is separated from combustion gases by alkali carbonates or other solutions which give it up again on heating, and the heating is effected to such an extent as to liberate steam with the carbonic acid so as to distribute the gas in a pipe system, the condensed water retaining any injurious impurity. The invention is described with reference to the supply of heat, steam, and carbonic acid to a greenhouse. The combustion gases from a stove 2 pass by a flue 1 into a packed tower 4 in which they are treated with alkali carbonate solution. The solution leaving the tower is filtered and returned by a pump 6 and pipe 7 to the boiler 3. Liquor is drawn from the upper part of that in the boiler by a pump 13 and pipe 14, and is sent through a cooling-pipe 15, which serves to heat the greenhouse, to the. nozzle 5 which supplies the tower 4. The carbonic acid and steam liberated in the boiler 3 are drawn off by a pipe 16 leading to perforated pipes 8, 12 'n the greenhouse. Carbonic acid with some steam escapes into the greenhouse while some of the steam condenses and retains any sulphur dioxide present. The condensate flows by a pipe 9 to a vessel 10 in which it is neutralized by caustic soda and is returned to the boiler 3 by a pump 11.

Title: Device for replacing used gloves in a glove box
Inventor: CLIQUE ALAIN-MARIE
IPC: G21F7/053
Filed: 1971-04-19
Abstract: 1,273,926. Glove boxes. COMMISSARIAT A L'ENERGE ATOMIQUE. 19 April, 1971 [4 Feb., 1970], No. 20925/71. Heading B4Q. A device for replacing a used outer glove 7 by a new glove 10 in a double-walled glove box having an inner wall 1 and outer wall 2, the wall 1 having a glove ring 3 of smaller diameter than the ring 4 of wall 2, comprises a tubular body 8 which is placed in position within the ring 4 after removal of an inner glove (not shown) located in a groove 5 on the ring 4, this glove extending into the interior of the glove 7. Prior to positioning the device the new glove 10 is attached thereto as shown by turning the gauntlet inside out and placing the glove bead 14 in a groove 13 formed in a skirt 12 of the body 8. When it is required to change the glove 7 it is moved manually from the groove 5 to the groove 6 of the ring 3 and the inner glove is then removed from the ring 4. The device is then placed in position. This device comprises a sleeve 16 having a chamfered end surface 16a is slidably mounted on the body 8 but is prevented from rotation thereon by slots 20 cooperating with stops 18 on the body. Rotation of the assembly 8, 16 relatively to the rings 3, 4 is prevented by a collar 24 having arms 22 extending through the slots 20, screws 28 in the arms being clamped against the groove 6 of ring 4. Springs 26 acting between the collar 24 and the body 8 bias the latter so that the end surface 12a of the skirt 12 causes the glove 10 to abut the inner wall 1 and effect a seal therewith. Thus the used glove 7 may now be detached and drawn into the glove box without leakage of the glove box atmosphere. A ring 30 is rotatably mounted on the body 8 between guides 32 and operating arms 34 on the ring extend through a helical slot 36 in the sleeve 16. These arms 34 are moved along the slot so  that the sleeve 16 moves axially towards the wall 1 causing the glove bead 14 to leave the groove 13 and abut the wall, further movement of the arms causing the assembly 8, 16 to move away from the wall against the action of springs 26 and the bead 14 slides on to the ring 3. A slight pull on the glove 10 brings the bead 14 into groove 5. The screws 28 are now loosened and the device removed and the inner glove is replaced in the ring 4.

Title: Web advancing mechanism
IPC: G03B1/18
Filed: 1971-04-19
Abstract: 1349857 Cinematography EASTMAN KODAK CO 19 April 1971 [6 Feb 1970] 21018/71 Heading G2E A mechanism particularly for the transport of unperforated film includes a continuous, flexible, transparent belt 21 which carries film 11 through an area illuminated by lamp 12. The film 11 is drawn from a spool 14 and received on spool 24. Roll 17 is driven by motor 18 and rolls 22, 23 rotate due to contact with the belt 21. The belt 21 is of a shallow U-cross section so that the film 11 fits therein and does not project above and is fictionally gripped by its sides. The film may be advanced intermittently or continuously. In the former arrangement a regular pulse from a clock circuit (72), Fig. 3, (not shown), causes an amplified output from a waveform generator (73) to drive the motor 18 long enough to move the film through one frame. The same pulse from the clock (72) is also electronically delayed so that it can actuate an optical detector (74) to determine whether the frame is correctly aligned for projection and, if not, to send a correction signal to the motor 18 to reposition the frame. In an alternative circuit, Fig. 5, (not shown), no correction signal is transmitted to the motor 18 but a differential optical detector (94) checks the position of the frame as before and by combination of its output with a reference signal from a source (102) the net signal modifies the gain of amplifier (93) which amplifies the signal from the waveform generator to the motor 18 to correct subsequent film movements.

Abstract: 1,209,115. Electrostatic recording heads. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 3 May, 1968 [6 May, 1967], No. 21032/68. Heading G5R. Information is electrostatically recorded on, or erased from, an insulating carrier 2 by an electrode 5 housed in an insulating member 1 having a sharp edge, the electrode being located "upstream" of the edge; and a conducting layer 3, which may be attached to the carrier 2, being located on the side of the carrier remote from the member 1. The electrode is spaced from the edge slightly less than a critical distance d 1  below which charge density varies linearly with the applied voltage. Recording is effected with a D.C. bias of, e.g. 600 V and optionally a H.F. bias voltage. Erasing is effected by applying a H.F. bias voltage. Cleaning.-The member 1 may be oscillated at twice the H.F. bias frequency such that the sharp edge contacts the carrier at the maximum amplitude of the bias. This is said to remove impurities.

Abstract: 673,604. Amplifying circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Aug. 25, 1950 [Aug. 30, 1949], No. 21069/50. Class 40 (iv). [Also in Group XL (c)] An amplifier comprises a valve stage and a transistor stage fed from the same supply source, the input being applied to one stage and the output being derived from the other, a D.C. coupling being provided between the stages. As shown, N-type transistors are connected to the output of the valve stages shown in Figs. 1 and 2 and P-type in Fig. 3, the resistances being chosen such that in Figs. 1 and 2 with respect to the base electrode 6 the input electrode is slightly positive and the output electrode 8 considerably negative, whereas in Fig. 3 and Fig. 7 (not shown) the input electrode is slightly negative and the output electrode considerably positive. The D.C. level of the output voltages is suitable for direct connection to a similar succeeding stage (Figs. 4 and 5, not shown), and in such an arrangement positive feed-back may be applied by means of a resistor between electrode 8 and the preceding grid and overall feed-back may be provided to reduce the gain to the value produced without the positive feed-back. In Fig. 1 positive feed-back is provided by resistor 15 and negative feed-back by resistor 18 and the effect on the input impedance of the base electrode resistor 9 may be neutralized by a suitable choice of the output resistor 10. In the Fig. 2 circuit the cathode resistor 3 may be omitted (Fig. 4, not shown). Pushpull output potentials may be obtained from between the valve anode and base electrode of either circuit (Figs. 6 and 7, not shown), providing approximately equal D.C. biases for the succeeding valves. The transistor may be structionally combined with the valve and an internal connection provided between the two in order to save valve pins.

Title: Improvements relating to the indicating and recording of variable quantities
IPC: G01N27/22
Filed: 1947-08-01
Abstract: 654,064. Electric measuring apparatus. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Aug. 1 1947, Nos. 21095 and 21096. Convention dates, Aug. 5, 1946 and July 19, 1947. [Class 37] [Also in Group XIX] The invention is based on the contention that each of a family of curves can be represented by a point in a plane thus, if there is a family of exponential curves of which 1, 2, Fig. 1, are members, each can be represented by points 9, 10 obtained by drawing horizontal lines 3, 4 intersecting the curves, and drawing from the points of intersection lines at, e.g. 45 degrees to the axes. According to the invention, recording apparatus makes a line record at one predetermined value of one of the variables, and, at another predetermined value makes a second line record intersecting the first line to define the point stated to be representative of the curve. As shown in Fig. 3, rotation of a screwed shaft 36 moves a paper carriage 35 under marking blades 31, 32, set at an angle and at the same time varies the resistance 23 in a circuit comprising a source of current 21 and apparatus 20 whose nature is not specified but whose response with variation of input voltage is to be investigated. When, as a result of the resistance variation, the output of 20 reaches one predetermined level, a relay 28 is actuated to cause the vertical blade 31 to mark, when the output of 20 reaches the second predetermined value, relay 29 is actuated to cause blade 32 to mark. If this operation is performed repeatedly with different values of a particular component in 20, a series of points of intersection of blades 31, 32 is obtained representative of the effect of varying that component. When the curves are resonance curves as in Fig. 2, the apparatus is arranged to record at one value when increasing and at the same value when decreasing. This application is illustrated in Fig. 6, which shows apparatus for measuring moisture content. An oscillator 54 has its frequency varied cyclically by cyclical variation of condenser 53 in synchronism with the traverse of the record paper ; the moisture content of the material in condenser 66 determines the resonant frequency of the circuit 64, 65, and as the frequency increases the output of 64, 66 increases until it reaches a pre-determined value when relay 47 energizes to energize one of the marking relays 50, 51 over change-over switch 52 ; when the frequency has reached its maximum, it begins to decrease, and the traverse of the record paper is reversed, this reversal changing-over switch 52, so that when the predetermined value of the output of 64, 66 is again reached, relay 47 is again energized to energize the other marking relay. In this way the lines 14, 15, Fig. 2, and 14, 16 are produced to define the point 14 indicative of curve 11.

Title: Improvements in or relating to supports or brackets for small electric generators
IPC: B62J6/06
Filed: 1935-07-25
Abstract: 460,246. Dynamo supports. COOKE, N. July 25, 1935, No. 21123. [Class 35] In a support or bracket for small electric generators as used for cycle lighting &c., a spring or the equivalent maintains the roller on the generator spindle in contact with the driving means and in addition, a safety catch is provided which is released to permit the generator to move into an inoperative position when the force tending to move the roller away from the driving means exceeds a predetermined value. A clip A clamped to a part B of the front or rear fork of a bicycle is formed integrally with a flat plate A<2> to which is fixed a bearing plate C having a pin D which serves as a pivot for a substantially circular disc E at one end of an arm E<1> carrying the generator F. A spring D<2> acting between the plate A<2> and an adjustable nut D<1> on the pin D presses the adjacent surfaces of the plate C and disc E together. The plate C is formed with three or another number of sockets symmetrically disposed about the pivot pin, and steel balls G in these sockets project into recesses E<2>, E<3> arranged in two series in the disc E. When the disc E is turned so that the balls project into the recesses E<2>, the generator is in the operative position, whereas undue pressure tending to separate the roller F<2> from the tyre B<1>, e.g. due to clothing &c. being caught between the roller and the wheel, causes the disc E to turn until the balls engage the recesses E<3> and the generator is in the inoperative position. The generator is pivotally mounted on the arm E<1> by means of a pivot rod F<1> mounted on or forming part of the casing F and pivoting in a hollow bearing member H carried by a housing E<4> formed integrally with the arm E<1>. A spring J acts to turn the generator so as to urge the roller F<2> into contact with the tyre and this movement is limited by a stop H<2> co-operating with a pin F<4> on the pivot F<1>. The pivotal axis of the generator is arranged at an angle of about 35‹ to the wheel axis so that when the generator is moved about its pivot to contact with the cycle wheel, the movement of the roller is partly in the direction of the normal motion of the wheel so that the action of the spring is supplemented. Specification 453,152 is referred to in the Provisional Specification.
