Title: Improvements in or relating to cigarette making machines
IPC: A24C5/32
Filed: 1935-04-08
Abstract: 447,705. Endless-belt conveyers. RUAU, F. F., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. April 8, 1935, No. 10823. [Class 78 (i)] In the delivery of cork-tipped cigarettes or cigarettes with printed matter from machines of the continuous-rod type, successive cigarettes cut from the rod' have the tips &c. pointing in opposite directions. In order to arrange the cigarettes for packing &c. it is necessary that all similar ends of the cigarettes lie in the same direction, and the invention provides means for reversing the cigarettes of one order on the conveyer, so that all cigarettes shall be delivered lying the same way. As shown, tipped cigarettes 1 are brought from the cut-off mechanism of a rod machine by a conveyer 2, and alternate cigarettes are fed on to a continuously moving conveyer 4 by deflectors 3 in two rows, axially transverse to the movement of the conveyer and slightly spaced apart, the tips in the row C being oppositely disposed to those in the row D. A device 5 is arranged above the conveyer to reverse the cigarettes in the row C. The device comprises four suction heads 6 at right angles to each other, capable of rotary movement. In the position shown in Fig. 2, a group of cigarettes in the row C has collected against a lip 11<a> on the underside of the suction head. At this moment a valve 12 is rotated to connect the suction to the right hand head, causing it to pick up the batch of cigarettes thereunder, and to disconnect the left hand head, which drops a reversed batch again on the conveyer. The valve 12 is operated from a cam 14 by links 15, 16 and the intermittent rotation of the heads is effected by the engagement of a pin 11 on a crank 9 with slots on a spider 7 arranged above the heads. In a modified form, Fig. 4, the head 5 is continuously rotated by an elongated pinion 20 engaging a gear 21 and is raised and lowered at the appropriate times by a cam 22 and rollers 24. The cigarettes are collected by a stop 27 on a dividing rib 18.

Patent GB-437022-A (GB)
Title: The manufacture of copper salts
Filed: 1934-04-14
Abstract: Pure copper salts are obtained by a two stage process from solutions obtainable by lixiviating chlorinated roasted burnt pyrites containing copper.  In the first stage the copper is separated as a difficultly soluble copper salt containing the acid ions originally present in the lye, and in the second stage the separated copper salt is converted into a pure solid copper salt still containing the said acid ions.  Thus the copper may be separated as the double salt sodium sulphate-copper sulphate by adding a sodium salt and stirring at say 50 DEG  C., or as copper oxychloride by adding zinc hydroxide or oxychloride, or by adding copper and blowing air through the solution, or as cuprous chloride by means of sulphurous acid or copper.  From the double salt, copper sulphate or basic sulphate may be obtained, the copper oxychloride may be converted to chloride, and the cuprous chloride be purified by dissolving in common salt solution, separating the residue, and the pure salt be recovered by cooling or dilution with water.  According to the Provisional Specification, the cuprous chloride may be converted to cuprous hydroxide.  Reference has been directed by the Comptroller to Specifications 260,294 and 285,662, [both in Class 1 (iii)].

Title: Improvements in or connected with apparatus for indicating movements or positions of machinery or parts of apparatus or the like from a distance, and for transmitting actions or signals
IPC: B63H25/36
Filed: 1924-05-09
Abstract: 238,004. Knowsley Electrical Co., Ltd., Woodroffe, F. K., and Dawson, R. H. N. May 9, 1924. No Patent granted (Sealing fee not paid). Rudders, indicating position of.- In apparatus for signalling the movements of a ship's rudder head to a distance, in which a contact arm cooperates with resistances to vary the resultant field of electromagnets having a rotatable armature carrying a pointer, one or other of three lamps is lit when the pointer &c. is in its central or side positions. As shown in Fig. 1, a rudder head 13 operates a contact arm 1 through quadrants 14, 15 which are connected by chains &c. 16 to allow a small movement of the rudder without affecting the contact arm. The arm 1 has a contact 3 which engages two sets of resistance elements 4, 5 and a contact bar 6. The ends of the resistances 4, 5 are connected through electromagnets 23, 24 to magnets 17, 18 controlling a pivoted armature 19 and pointer 20. Located between the resistances 4, 5 is an insulated contact 10 which is connected to an electromagnet 30 and a white lamp 31. The contact 3 is of such a width that when in its central position it bridges the contact 10 and makes contact with the resistances 4, 5. In this position, the magnets 17, 18 are equally energized to hold the pointer illuminated. The magnet 30 holds an armature 25 against operation by one or other of the magnets 23, 24. When the arm 1 is deflected over one or other of the resistances 4. 5 the circuit of the magnet 30 and the lamps 31 is broken and the field of one or other of the magnets 17, 18 is strengthened whilst the other is weakened to move the pointer into its indicating position. Simultaneously, one or other of the magnets 23, 24 attracts the armature 25 to close one or other of the contacts 27, 28 of lamps 32, 33 which are red and green respectively. In the modification shown in Fig. 3, the arm 1 is directly connected to the receiver and the signalling lamps are controlled by contacts 26, 28 which are operated by a cam 40 on the pointer spindle. The cam has a contact which in the normal position of the pointer engages both contacts 26 to illuminate the lamp 31. A modified form of connection between the rudder head and the contact arm is shown in Fig. 4. A bar 42 on the rudder head 13 is connected to a bar 43 mounted on the contact arm by spring controlled plungers 44. The resistance sections 4, 5, Fig. 1, may be formed with plug and socket so as to ba readily removable in case of failure. The Provisional Specification refers to the use of a curved tubular lamp with coloured sections lit by separate filaments.

Abstract: 1,196,400. Vocoder synthesizer. INTERNATIONAL BUSINESS MACHINES CORP. 5 March, 1969 [7 March, 1968], No. 11656/69. Heading H4R. In a channel vocoder system excitation function characteristics are derived at the receiver, voiced/unvoiced switching being controlled by a comparison of the energy levels in the lower frequency channels relative the energy levels in the higher frequency channels, and the pitch frequency being generated at a frequency controlled in accordance with the energy levels in predetermined low-frequency channels. Fig. 1 shows a block diagram of a vocoder in which the energy levels in a number of frequency bands F1, F2, Fn &c., are determined and transmitted in P.C.M. multiples to a vocoder synthesizer where the channel signals are decoded and demultiplexed to provide energy level signals for the synthesis channels. The two lowest frequency channel signals are combined in an analogue " or " gate 7 and via amplifier 18 control the frequency of an oscillator 6 controlling the supply of excitation pulses to a switching device 10 which feeds either the excitation pulses or a noise signal from generator 12 to the synthesizer channels, depending on the form of the voiced/unvoiced signal A. The excitation signal is fed in a normal fashion via channel filters f 1 , f 2  &c., to modulators M1, M2 &c., fed with the respective channel energy level signals, to synthesize the speech. The energy level of the two lowest frequency channels is arranged to control the frequency of oscillator 6 inversely, so that an increase in energy produces a decrease in excitation frequency, this relation having been found to be consistent with normal speech. Fig. 5 shows a block diagram for the derivation of the voiced/ unvoiced switching signal A by comparing the total energy in channels 1 to i, i.e. channels in the region 250 to 5000 Hz. with the energy in channels j to n, i.e. channels in the region 5000 to 10,000 Hz. The comparison determining whether the original speech was voiced, i.e. energy mainly below 5000 Hz., or unvoiced, i.e. energy mainly above 5000 Hz. The energy level signals in the respective channels 1 to n are fed to the modulators via delay devices #t to synchronize the spectrum energy function signals with the excitation function derived from the channel energy signals.
