Filed: 1939-01-17
Abstract: 523,910. Distilling fatty acids. FOSTER WHEELER, Ltd. (Foster Wheeler Corporation). Jan. 17, 1939, No. 1585. [Class 32] Fatty acids are distilled from fatty acidcontaining stock by passing the stock .through a heating zone, fractionating the vapours formed in a fractionating tower in contact with reflux, and withdrawing overhead and from intermediate points in the fractionating zone the separated fatty acids, which are preferably stripped after withdrawal. A stock comprising a mixture of fatty acids is passed by a pump 11 through a heater 13, which may be heated in a furnace or through the medium of a heated liquid, into a fractionating tower 15 maintained under vacuum and heated at the bottom by superheated steam injected through line 18. Side fractions are taken off through lines 34, 44, to stripper towers 35, 45, from which intermediate acids are withdrawn through lines 42, 51. Vapors pass off from the top of the tower through line 21 and condenser 22 to receiver 24 from which steam is removed by the vacuum pumps through a catch all 28. Part of the condensate in the receiver 24 is recirculated through line 25 as reflux while the remainder is withdrawn through line 31. Heavy fractions may be recirculated through lines 54, 53 while the residues are withdrawn through line 58. The feed stock may comprise a mixture of palmitic, linoleic, oleic and stearic acids and is heated sufficiently to vaporise these from the residual tar and glycerides. The palmitic acid is taken overhead as vapor while the remaining acids are withdrawn as side streams.

In an electric winder system, one or more A.C. motors are arranged to be automatically operated by closed-loop control to provide the whole of the driving torque during periods of constant speed of the conveyance, and to provide this static component of torque during speed-change periods. Another motor, or group of motors, supplies a torque during accelerating and decelerating periods only, and its operation is by open-loop control. This auxiliary drive is automatically disconnected from the A.C. source during periods of constant speed of the conveyance, and is connected to provide an accelerating torque, dynamic braking torque, or a driving torque, opposing the conveyance motion at the time. The auxiliary drive may be controlled by switches situated at predetermined positions in a lift shaft for mechanical actuation by the conveyance, or by means of a speed-responsive switch. A position-switch in the shaft may also disconnect the auxiliary drive at the beginning of a creep period.

Abstract: 1,062,245. Transistor bi-stable circuits. SQUARE D CO. Jan. 18, 1965 [Jan. 16, 1964], No. 2069/65. Heading H3T. [Also in Division H2] In a bi-stable circuit a transistor TN4 is arranged to be rendered " conductive when initially connected to the supply. When a switch 88 is closed a capacitor C3 gradually charges to - 20 v. A diode D7 has a high forward resistance requiring 5 v. before it conducts. With all transistors non-conductive, the base of TN4, being fed through parallel sets of resistors R9, R16 and R10, R15, will be at a more negative potential than the base of TN3 hence TN4 will conduct first and ground the base of TN3. After the threshold potential of diode D7 has been overcome TN10 will conduct and ground the base of TN4 but this will be without effect due to the bias through resistors R10, R15. During this time the point B will be grounded in another part of the circuit (not shown). On the appearance of a negative voltage on B, TN3 will conduct again grounding the base of TN4 through R15 switching it off and removal of the signal on B will leave the circuit in this condition so that point 46 gives a negative output voltage.

Abstract: 1,023,662. Multiplex transmission systems. POSTMASTER GENERAL. Jan. 10, 1963 [Jan. 19, 1962], No. 2101/62. Heading H4R. A two wire carrier multichannel communication system has three terminal stations and four groups of communication channels allotted to each station, the stations being interconnected by a branching device such that transmission from a first to a second terminal station and vice-versa is by a first and a second group of channels, one group for each direction of transmission; transmission from the first to a third station is by a third and a fourth group, one for each direction of transmission, while transmission between the second and the third terminal stations takes place on the third and fourth group at the second station via a modulator which transposes the signals to the first and second group for handling at the third station. Fig. 2 shows diagrammatically the preferred allocation of channel groups between the three stations A, B and C. Two other arrangements are also described, Figs. 3 and 4 (not shown). Fig. 1 shows the arrangement of filters and the modulator in the preferred embodiment in which signals from terminal stations A, B and C are applied to the branching network via amplifiers 1, 2 and 3 and power supply filters PSF1, PSF2 and PSF3 respectively. Transmission between stations A and B takes place in the frequency bands 156 kc. to 300 kc. and 456 to 600 kc. via filters LPF1, HPF1, LPF2 and HPF2, HPF4, HPF3. Transmission between station A and C takes place in frequency bands 60 to 156 kc. and 360 to 456 kc. via filters LPF1, LPF3, LPF4 and HPF5, LPF5, HPF2. Transmission from station B to station C originates in the band 360 to 456 kc. and is applied via filters HPF3 and LPF6 to modulator M where it is transposed to the band 156 to 252 kc. and then fed via filters HPF7 and LPF4 to station C. In a similar fashion signals for station B originate at station C at 456 to 552 kc., are fed via filters HPF5, HPF8 and BSF1 to the modulator M, are transposed to the band 60 to 156 kc. and fed via filters LPF8 and LPF1, to station B. The carrier frequency of 612 kc. for modulator M is generated at station C and fed via filters HPF3, HPF8 and BPF1 to the modulator M, the band pass filter BPF1 preventing signal input to the carrier terminal of the modulator and band stop filter BSF1 preventing carrier input to the signal terminal of the modulator.

Abstract: 138,977. Medley, R. Jan. 30, 1919. Hoods.-The cant-rail is connected to the rear pillar by a pair of links so that it lies along the pillar in a contracted position when the hood is folded, and, during the folding movement, one of the links is adapted to break the joint of the rear stretcher-bars after a stop which holds these bars in the straightened position has been moved away by the other link. An intermediate hoop-stick mounted on the cant-rail is folded by connexions from one of the links. The links i, f extend respectively from pivots h<2>, f<3> on the cant-rail g to pivots i<3>, e<4> on the pillar a. Rigid with the pivot e<4> is a lever e connected to a spring plunger c, which urges one end e<5> of the lever e against the stretcher-bar d to hold it in the straightened position. The link i has an extension i<4> which is adapted to contact with an extension d<5> of the stretcher-bar, which bar is pivoted at d<2> on the pillar. Upon raising the forward end of the cantrail, the latter turns at first mainly about the pivot h<2> on the link i, thereby moving the link f downwardly and the end e<5> of the lever e away from the stretcher-bar d. The link i also then moves downwardly and effects the breaking of the joint d<4> of the stretcher-bar by the engagement of the part i<4> against the extension d<5>, and the rear part of the hood may be then folded with the cant-rail. A hoop-stick l is pivoted at l<2> on the cant-rail, and is folded by a link m connected at m<2> to the link i and to an arm n on the pivot l<2>.
