Title: Improvements in or relating to combing machines
IPC: D01G19/14
Filed: 1930-05-13
Abstract: 360,906. Combing - machines. NASMITH, J. W., Leegate, Mauldeth Road, Heaton Mersey, Manchester. May 13, 1930, No. 14672. [Class 120 (i).] In a combing-machine of the type described in Specification 344,102 having a detaching roller D forming a detaching nip with the combing cylinder segment, and which is caused to move towards and from the machine nipper N, the top comb reciprocating therewith over a lesser distance, the comb is given a slight dwell just before moving away from the nipper to offer resistance to the pull of the detaching means upon the fibre tuft and ensure a clean and even separation. The comb is also given a slight lift during the detaching operation to ease the pull and minimize the formation of waste. The detaching roller D is reciprocated by means of the weight-hook 4 hinged on a pin 1 fixed in a lever 2 which is pivoted on a stud 3 fixed in the framing, the lever 2 being rocked from a shaft W through the members L, R. The upper end of the lever 2 is adapted to engage a screw 5 in the top comb carrier 6 to give the ordinary lift to the top comb to clear the cylinder needles. The carrier 6 is connected to an arm 8 on a shaft 9 which is timed to oscillate relatively to the shaft W to produce the slight dwell of the top comb. When the lever 2 is out of contact with the screw 5 a bowl 14 on the carrier 6 rests on the horizontal arm of a two-armed lever 13 pivoted on a stud 12 fixed in a frame-member 10, the vertical arm, carrying an adjusting screw 17, engaging a set screw 15 carried by a vertical projection 11 of the frame 10, the screw 15 being adjusted so that the top comb needles are at the appropriate distance from the cylinder segment. When the detaching roller D is about to make contact with the cylinder segment the shaft 9 is displaced counterclockwise the comb being moved to the right, as shown at 18, the detaching roller D reaching the position 19. If the screw 17 is withdrawn from engagement with a second bowl 16 on the carrier 6 there will be no lift of the top comb. If the screw 17 is adjusted to rest against the bowl 16 when the displacement of the shaft 9 begins the lever 13 will be turned on its pivot 12 and the horizontal arm will raise the comb from the cylinder.

Title: Telecommunication switching systems
IPC: H04Q1/18
Filed: 1944-08-01
Abstract: 600,504. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Aug. 1, 1944, No. 14672. Convention date, Aug. 28, 1943. [Class 40 (iv)] [Also in Croup XXXVII] A register-controller comprises ten pairs of thermionic tubes, Fig. 2, each associated with a coldcathode tube GV and a relay GVR, each pair being differently biassed and incoming numerical signals, consisting of brief impulses of different polarity, being applied to all the pairs simultaneously over a wire 6. In one arrangement, a calling PBX subscriber takes into use the circuit shown in Fig. 1, in which DR pulls up over the loop, locks and energizes HR, MR. By means of a keyboard, the subscriber now sends single short impulses of characteristic voltages from a local potential divider fed by the exchange battery or by a local rectifier over the b wire and at each keyoperation unlocks DR shortly before the impulse is generated. The impulse thus passes to the wire 6. The associated relay GVR then energizes appropriate relays of a 4- relay register such as XR1 ... XR4. These energize a transfer relay such as TR1 to ensure the registration of the next digit on another register (not shown). The registers control the selectors by applying a characteristic potential as described in Specification 592,846. When the register-controller has completed its function, it grounds wire 8 to cause CR to switch through. In a modification, Fig. 3, ordinary impulses are dialled to a register-switch associated with the outgoing end of a junction and this selects a characteristic potential for application over the b wire of the junction in the interval between the relapse of the dialling relay BR and a relay ICR controlled by it. The register subsequently goes home in readiness for the next digit. JR at the incoming end, which operates initially to energize IHR and remains locked, is unlocked when BR falls back to connect the b wire to the wire 6 of the register-controller and re-operates when ICR falls back. When wire 8 is grounded, QR operates to release THR. When the called party replies. ISR energizes KR., which completes the talking circuit 4, reverses the connections of VR to operate a supervisory relay MR. Specification 577,088 also is referred to. Sub-station keyboard. The depression of any key slides a bar 14 to the left and with it a contact-carrying bar 18 which is engaged by a pivoted latch 20. Contact which is normally made between 24, 25 is thus broken (to release DR or JR) and subsequently contact is made between 24 and 26 (to complete the feed-circuit to the potential divider). At the same time the individual key contacts 16, 17 apply the selected potential to the b wire. In the extreme position of the key, the latch member 20 is disengaged from the bar 18 and the contact 24 returns to the position shown.

A copying machine comprises a latent image storage means which is internally polarized by the application of radiation and an electric field, means for subjecting the image storage means to a radiation image to selectively discharge areas of the storage means, means for dispensing toner over the storage means, means for transferring the toner from the storage means to a member for permanent retention, means for irradiating the storage means to destroy the residual polarization therein, means for removing residual toner therefrom and means for transporting the storage means past each of these means. A conductive drum 20 carries plates 21a - 21c which exhibit persistent internal polarization. The plates have photoconductive particles dispersed in a matrix 23, Fig.2 secured to the drum 20 and preferably covered by a transparent electrically insulating layer 25. The photo-conductive particles may be zinc cadmium sulphide, alkali halides, anthracene or chrysene. The matrix may be cyclicized rubber, cellulose nitrate, polyvinyl acetate acrylonitrile - butadiene - styrene terpolymer, oxidized polystyrene styrenated alkyd and polyvinylidene chloride - acrylonitrile copolymers. At station A, Fig. 1 the plate 21a is uniformly exposed to a filament 27 within a N E S A tube 26 having an external coating of tin oxide. Simultaneously or sequentially an electric field is applied between coating 28 and drum 20. Due to P I P, the plate becomes charged as shown, in Fig.3. At station B Fig. 1 the previously charged plate is imagewise exposed e. g. by a flying spot scanner or by an optical system causing certain charged areas to be discharged or the charges to be weakened. In a modification, a reverse field can be applied by an electrode (37) Fig. 5 (not shown) to produce a charge pattern Fig. 5a (not shown). The charge pattern may be developed with two colour toner (46, 47). At station C, Fig. 1, a hopper 41 dispenses toner through openings 44. The toner may be dry powder e. g. nigrosine dye impregnated with polystyrene mixed with iron powder or toner suspended in a carrier e.g. carbon black in kerosene, petroleum ether or (Registered Trade Mark) "Freon" The developed image is transferred at station D to a sheet 49 by contact preferably assisted by a potential difference applied between drum 20 and roller 50. In the case of a dry toner a fixing device is provided. Free residual charges on the plates are eliminated by flooding with radiation from a photo-flood or infrared lamp 51 at station E. Residual toner is removed by a brush 52 at station F. In a modification, the insulating layer 25 is replaced by a conductive layer in contact with the plates 21a - 21f. If desired stations, A, E and F may be combined so that residual charges and toner are removed by light or light and applied field acting simultaneously or sequentially. By deactivating stations C, D, and F multiple copies are produced from a single exposure.
