Title: Improvements in or relating to sealing devices
IPC: F16J15/38
Filed: 1968-12-11
Abstract: 1,201,975. Seals. ETABS. POMPES GUINABD S.A. 11 Dec., 1968 [18 Dec., 1967], No. 58837/68. Heading F2B.  A standby seal 3, 8 for a pump 2 or compressor is brought into operation in the event of deterioration of a normally operative seal 16, 18 by means of a piston assembly 14, 10 in communication with the leakage fluid recovered at the outlet 31. A further mechanical seal 22, 23 and a floating ring seal 24 are also provided downstream of the other seals. Normal leakage occurs through the seal 16, 18 at 29 and a pump 33 returns it to the pump 2 at 35. A diaphragm or constriction 36 is set so that normally the pressure in the line 39 and passage 38 is unable to displace piston assembly 14, 10. When the leakage flow exceeds a given value, the increased pressure in the passage 38 moves the piston assembly 14, 10 and seal ring 8 into engagement with rotary seal ring 3 which is supported by springs 6 on a shaft sleeve 4. If the main seal 16, 18 regains its sealing function after being momentarily put out of action because of sudden heating or entry of a foreign body, the drop in pressure at 38 and the increase in pressure at 35 causes the assembly 8, 10, 14 to move to the right out of engagement. The main and standby seals may also be put into or out of action manually by use of valves 40, 41; the closing of the valve 40 causes an increase in pressure in the passage 38 and consequent movement of the assembly 8, 10, 14 to the left while the operation of the valve cock 41 diverts part of the pump delivery into a passage 42 causing movement of the assembly 8, 10, 14 to the right. Secondary seals 9, 20 allow the seal rings 8, 18 to tilt.

Patent GB-681866-A (GB)
Abstract: 681,866. Workmen's time-recorders. NILSON, C. E. J. Sept. 1, 1950 [Sept. 9, 1949], No. 21642/50. Class 106 (iv). A workmen's time-recorder comprising a series of type-wheels and two card-funnels one behind the other is provided with card-actuated mechanism such that upon insertion of a card into one funnel printing from some only of the type-wheels is effected, whilst upon insertion of a card into the other funnel printing from all the type wheels is effected. A movable card-funnel 11 comprising an orifice 14 and guide bars 12, 13, is moved in front of a fixed funnel 10, comprising an orifice 17 and guide bars 15, 16 by means of a screw 44 working in two cars 55, 56 of the funnel 11 and the front part of the funnel 10 forms a partition 18 extending across the whole path of the funnel 11. Printing is effected on a card 35 when one or both hammers 23, 24 press the card against type-wheels 19-22 with a typewriter ribbon intervening. The wheels 19, 20 bear minute and hour digits while the wheels 21, 22 record day and week number or other data such as day and month and other wheels may be provided to record other time particulars such as total working hours. The correct insertion of a card into either funnel completes a circuit to an electromagnet 41 which then attracts its armature 42 and rocks an arm 45 about an axis 25 so that a peg 46 pushes the hammer 23 forward to print minutes and hours. If the card is inserted in the fixed funnel 10 it depresses an arm 26 pivoted at a fixed point 27 causing an arm 30 to move against a spring 32 to engage a peg 31 in a slot 34 of the hammer 23 so that the peg 31 moves forward with the hammer 23 and also pushes forward the hammer 24 to print the remaining data. To avoid damaging the card upon withdrawal the tip 51 of the arm 26 is pivoted at 53 and drawn against a stop 54 by a spring 52.
Patent GB-713631-A (GB)
Abstract: 713,631. Telemetering. GENERAL ELECTRIC CO., Ltd. Jan. 16, 1951 [Jan. 25, 1950], No. 1987/50. Class 40(1). In a system for transmitting intelligence originating at random from a plurality of sources, e.g., changes in the readings of meters M1-M40, the message sources are grouped so that the mean rates at which messages originate in the several groups are. approximately equal; the groups are connected to respective primary selectors PD1, PD2-PD4, each of which selects from its group one source with a message to be sent, the intelligence therefrom being transmitted together with a signal identifying the source within the group, over a secondary selector SD. In the embodimentshown each primary selector hunts until it reaches a contact corresponding to a meter in which the reading has changed and the change in this meter reading is transmitted from therespective group during the next rotation of the secondary selector SD which is motor-driven and preferably synchronised with a corresponding distributer at the receiver e.g., by means of synchronising pulses sent once per revolution when an auxiliary wiper MC1 engages contacts CX1, CX2. With the secondary distributer synchronised in this way, no signal identifying the operative primary selector is necessary. The meters of a group, e.g., M1-M10 are assumed to be ammeters, and as shown for M5, Fig. 2, are series connected with an associated resistor R2 to produce a voltage on the left hand plate of a condenser C2 proportional to the meter reading. After transmission of a meter reading the right hand plate of the associated condenser C2 is temporarily clamped to zero potential by a clamp circuit CL, Fig. 5 (not shown), so that only if the meter reading subsequently changes is the potential of the associated selector contact varied from zero. Assuming the reading of M5 has changed sufficiently to require transmission, the voltage on the associated selector contact, is, when the selector PD1 reaches this contact, amplified at AMP, Fig. 3 (not shown), to produce a corresponding +ve output whether the input is +ve or-ve, and passed to a relay circuit REL, Fig. 4 (not shown), to stop the motor MR driving the selector. The primary selector is held in this position while the secondary selector wiper MC explores the associated' contacts FC1, FC<SP>1</SP>1. Over FC1 a voltage of magnitude indicative of the meter M5 in the group M1-M10, and derived from a potentiometer VR over a second bank of the primary selector, is fed to the coder PCM., after which a voltage taken from the amplifier AMP and proportional to the change in the meter reading is fed over contact FC<SP>1</SP>1 to the coder for transmission. As the wiper MC leaves contact FC<SP>1</SP>1 a +ve pulse is sent over a second bank SD1 of the secondary selector to the clamp circuit to earth the right hand plate of condenser C2, Fig. 2, associated with meter M5, as above described, and also to the relay circuit REL to start the motor MR so that the primary selector PD1 again hunts. The secondary selector SD may be replaced by an electronic distributer.

Patent GB-2006539-A (GB)
Title: Dual Evanescent Mode Waveguide Filter
IPC: H01P1/208
Filed: 1978-07-28
Abstract: A waveguide filter incorporates both dual mode operation, in which orthogonally plane polarised waves traverse the same filter cavity, and evanescent operation at a frequency below the cut-off frequency of the guide. The combination of dual-mode and evanescent-mode operation is achieved by the introduction of capacitive susceptance (11) balanced between the orthogonal modes. Different coupling coefficients, and therefore different transmission characteristics, for the two orthogonal modes are obtained by differential loading of the resonant cavities. This is achieved by differential inductive susceptances (13) having e.g. three posts extending in one orthogonal direction and two in the other. <IMAGE>

Title: Selectible adsorption from solutions such as coffee extracts
IPC: A23F5/22
Filed: 1978-08-07
Abstract: The selectivity of an adsorbent for the preferential adsorbed component of a multi-component aqueous solution (e.g. caffeine in aqueous coffee extracts) is improved by means of passing an aqueous solution 21 of the adsorbed solids eluted from the most spent stage 1 of a multi-stage countercurrent adsorption process 2-4 through a fresh bed 5 of the same adsorbent to produce at least initially a solution 40 containing substantially no preferentially adsorbed component. The solution 21 is obtained by treating the bed 1 with a desorbent 19, removing the desorbent at 7 and concentrating at 8 if necessary, and the bed 5 is treated with a desorbent 43 to recover the preferentially adsorbed component as a solution 44. By means of this process the preferentially adsorbed component is concentrated in the fresh bed. The adsorbent may comprise non-ionogenic, macroreticular particles of, e.g., divinylbenzene polymer or styrene-divinylbenzene copolymer. <IMAGE>
