Title: Improvements in and relating to eccentric epicyclic gearing
IPC: F16H1/32
Filed: 1935-03-25
Abstract: 447,444. Eccentric epicyclic gearing ; pulleyhoists. FLIESBERG, E. A. M., 4, Stora Mossens Backe, Appelviken, Sweden. March 25, 1935, No. 9206. [Class 80 (i)] [See also Group XXX] In an eccentric epicyclic gear in which the middle radial planes of the gear wheels coincide, the driving member is journalled in the casing and carries the eccentric, which has a concentric bore to receive the driven member. The driving and driven members may be reversed. In the pulley block shown in Fig. 1, the driving shaft 1 is supported in the frame 3 at each end by self - aligning bearings 2, 5. The hoisting wheel 13 is supported on the shaft 1 by a bearing 14 and by a sleeve 15 supported inside the eccentric 17 by a needle bearing 16. The eccentric 17 is secured to the end 18 of the shaft 1 and supports the double gyrating gear 21, 22, which engages the fixed rim of teeth 24 and the gear 23 on the wheel 13. The driving wheel 7 is connected to the shaft 1 through a slipping coupling 9. In the gear shown in Fig. 2, the driven gear 29 is mounted in the casing 30 by a self-aligning ball-bearing 31, and is secured to a driven shaft 28 supported by needle bearings 33 within a sleeve 34 secured to the driving shaft 44 and carrying the eccentric 35, whose internal eccentric surface 351 supports, through a needle bearing 36, the gyrating gear 37. The sleeve 34 is supported by the self-aligning ball bearing 43 in the hub of the gear 42, which is fixed in the casing. The outer surface of the eccentric 35 is also eccentric so that the eccentric acts as a counterweight to the gyrating gear. The sum of the heights of the teeth in the co-operating gear-wheels is preferably not greater than the eccentricity so that there may be only a small difference in the number of teeth (say 1 to 4) in the different wheels. The pressure angle is preferably not more than 35‹. The addenda of the internal teeth may be half as high as those of the external teeth co-operating with them.

Title: Arrangements for monitoring ionising radiation
IPC: G01T1/16
Filed: 1972-02-29
Abstract: 1346711 Monitoring ionizing radiation INTERNATIONAL STANDARD ELECTRIC CORP 29 Feb 1972 [1 March 1971] 9238/72 Heading G1A In a supervisory circuit monitoring a measuring device which comprises a measuring channel(s) 1, 2 including an ionizing radiation source(s) 5, 6 and a detector(s) 8, 9, a reference source of radiation 7 and a detector 10 are selected such that the dose rate of reference source 7 should be less than (or greater than) the dose rate(s) due to radiation source(s) 5, 6, and the count rate from each detector 8, 9 and 10 of each channel is converted to an analogue electrical signal in corresponding converters 15, 16, 17, the analogue electric signals due to source(s) 5, 6 being compared in a comparator 21 with the analogue signal due to the reference source 7, wherein the comparator operates an alarm 22 when the measuring signal(s) are smaller than (or greater than) the reference signal. The converter circuit may comprise a buffer amplifier, an integrating element, and an analogue amplifier (Fig.3, not shown). The comparator circuit may comprise two differential amplifiers for measuring channels 1 and 2 each amplifier also receiving the reference signal, the outputs from the differential amplifiers being fed to a comparator including a reference voltage or current which sets a threshold for an output by the comparator and the reference source is chosen so that one measuring signal is usually greater than the reference signal and one is usually less. In a further similar embodiment, Fig.4, the converter circuits 15, 16 and 17 each comprise a gate 40, a digital counter 41 and a digital-toanalogue converter 42. When a digital counting circuit reaches a predetermined count (erase count) the digital counting circuit produces on a reset line 44 a pulse which via an OR circuit 45 resets the digital counting circuit 41 to zero and during this operation blocks via a further OR circuit 46 the gate circuit 40 to counting pulses. As shown the reset line 44 of each converter arrangement is connected to the reset inputs of all other converter arrangements. The outputs are connected to differential amplifiers 36, 37 as shown whose outputs pass via an OR circuit to an alarm or recording device 22.

Title: Improvements in and relating to automatic switching systems
IPC: H02H3/06
Filed: 1925-04-07
Abstract: 232,226. British Thomson-Houston Co., Ltd., (Assignees of McDonald, U. R.). April 8, 1924, [Convention date]. Cut-out arrangements.-In systems wherein a generator 1 is connected to a load circuit 2 through two or more switches e.g. 3, 4, of which one, 3, on closing connects the source to the load circuit through a resistor or resistors 5, afterwards shortcircuited by the closing of the other switch or switches e.g. 4, which cannot close till the first switch is closed, means are provided to prevent the later switch or switches from closing until the current which will be supplied on its or their closing is less than the pick-up value of the overload relay 9. As shown in Fig. 1, closing of the switch 7 closes the circuit-breaker 3, with the circuit for the coil 8 of the short-circuiting switch 4 left open, but, the contacts 18 being bridged, a voltage relay 12 is put in between the load circuit and the generator, so that, if there is no overload &c. on the circuit or as such an overload clears, the contacts 15 are bridged and the switch 4 closed. In the modification shown in Fig. 2, the switch 4 is a latched-in circuit-breaker and a current relay 25 put into the load circuit so cooperates with a coil 31 that it can only close its contacts 32 when the coil 31 is de-energized. As before, the switch 7 closes a circuit to operate the switch 3 and so closes at 16 a locking circuit for the coil 6 and at 30 a circuit for the coil 31, whose coil 28 after a predetermined time moves up and thus allows the relay 25, as soon as the conditions in the load circuit are satisfactory, to break contacts 32 and complete at 27 circuit for the coil 8 of the short-circuiting switch 4, which is latched at 29 on closing and its coil circuit broken at 34. In a further modincation, there are a number of short-circuiting switches combined with resistors and operating both ways in sequence so as to introduce or take out resistance gradually. One of the breakers is of the kind described in Specification 187,993 and is adjusted only to open in the case of severe overloads and short-circuits when it immediately opens the main circuit-breaker 3.

Title: Process and apparatus for recovery of carbon disulphide or other solvents
IPC: C01B31/26
Filed: 1937-04-03
Abstract: In recovering solvents of low solubility in water from gaseous mixtures containing troublesome impurities such as sulphuretted, arsenetted or selenietted hydrogen, by the aid of solid or liquid absorbents, the gaseous mixtures are freed from the troublesome impurities prior to the absorption by being contacted with activated carbon highly charged with water, the carbon employed in this initial purification being periodically regenerated by a suitable washing, e.g. with a dilute sodium carbonate solution or superheated steam. The process may be applied to the recovery of carbon disulphide, ethyl ether, benzene, ethers, esters and other paraffinic or aromatic hydrocarbons.  The initial treatment with water-charged activated carbon may be preceded by a preliminary washing with water to remove a part of the impurities.  The subsequent recovery of the solvents may be carried out in known p  manner, e.g. by means of dry activated carbon, silica gel or oil-washing.
