Patent GB-357919-A (GB)
Title: An improved process for washing and after-treating filaments, strips or the like of artificial silk spun in the form of spun cakes
IPC: D01D10/04
Filed: 1931-02-14
Abstract: <PICT:0357919/IV/1> A plurality of spun cakes of artificial silk is subjected to the various wet treatment processes in an ordinary large centrifuge, each cake having been wrapped up in, or bound up in, a wide meshed, net-like fabric and pressed to form a flat skein or hank. The fabric used for protecting the cakes may be of the nature of the so called hair-nets, and may be in the form of a tube; artificial silk is preferably used as filament material for the fabric, but twisted cotton yarn is also suitable.  The cakes are wrapped by inserting the tube-like fabric through the cake so that the end of the tube projecting at the top may be turned over outwardly and caused to embrace the whole cake; in a similar manner the end of the tube projecting underneath the cake is bent over outwardly and caused to embrace the cake.  Alternatively, the tubular fabric may first be drawn over the exterior of the cake and the ends then inserted through the cake.  The length of the tube may be just sufficient to pass round the cake and in this case, the fabric is provided at both ends with strings which are tied together as soon as the tube has been drawn over the cake on all sides.  The assembled cakes 1 are placed in the centrifuge 2 preferably by arranging several circular series in one layer in a radial direction and a series of such layers are arranged one above the other.  The treatment liquids are introduced into the interior of the centrifuge through the perforated spray tube 3 and are atomized against the layers of spun cakes after the centrifuge has been started up.  The cage of the centrifuge may be made resistant to all the treatment baths such as acids and salts, desulphurizing baths, bleaching baths, and scrooping baths.  For this purpose the cage and other moving parts of the centrifuge may be made of a special resistant steel or of an artificial material. The non-resistant metal parts may be coated with protective layers for example a noble metal or an artificial substance.  Coatings of hard rubber are suitable when the centrifuge is to be used for acid treatment, and ordinary iron is suitable for alkaline treatment as in the case of desulphurizing. Separate centrifuges may be employed for the acid and the alkaline treatments.

Title: Improvements in or relating to telegraph receivers
IPC: H04L27/233
Filed: 1935-02-15
Abstract: 436,188. Induction relays. SOC.FRANCAISE RADIO-ELECTRIQUE, 79, Boulevard Haussmann, Paris. Feb. 15, 1935, No. 4970. Convention date, Feb. 15, 1934. [Class 38 (v)] [See also Group XL] Telegraph signals, sent by varying the phase of a radio frequency signalling current to distinguish " marks " from " spaces," are received by beating the incoming signal with a local polyphase current of about the same frequency, setting up a rotating field by the polyphase beat current, and utilizing such field to actuate indicating- apparatus. The system does not require exact synchronism between the incoming signal and the local source. In the receiving relay shown, the coils 14a, 14b are located in slots in a rotor mounted on a vertical spindle, the two-phase beat current being led in through slip rings 13. The rotor can turn freely within a stator formed by semicircular magnets 16 with upstanding like poles 17 separated by air gaps. A magnetic needle 18 is freely pivoted at 19 on the rotor spindle and passes through the two gaps. At one end the needle is centralized by light springs 21 and the other end lies between fixed contacts 20. When signal transmission is started, the rotor slowly rotates at the beat frequency (or is stationary if the local oscillator is in strict synchronism) and the needle lies between the contact 29. With a sudden change of phase due to keying, the rotor tends to jerk forward or backward, but is prevented by its inertia. Owing to the change of flux direction in the rotor, however, the light needle 18 will be displaced on to one or other of the contacts 20 which may be connected in the circuit of a recorder or telephone. In a modified construction of relay, Fig. 6 (not shown), the stator is divided in a horizontal plane, the lower sections being permanent magnets, whilst the upper sections with the upstanding arms 17 are of soft iron.

Title: Improvements in or relating to the manufacture of crown stoppers for containers
IPC: B21D51/48
Filed: 1950-02-28
Abstract: 677,745. Making crown stoppers. CROWN CORK CO., Ltd., and BECK, N. Feb. 28, 1951 [Feb. 28, 1950], No. 5118/50. Classes 83 (ii) and 83 (iv). Stamping.- A machine for making crown stoppers for containers of the type in which sheet stock is fed between opposed tubular dies one of which is movable and has its cutting edge on its outer circumference, the other stationary die having its cutting edge on its inner circumference is characterized in that corrugation-forming serrations are located on the movable cutting die or on a member nested therein and the said movable cutting die is directed against that face of the blank which will be the upper face of the finished crown when the crown is in position on the top of the container. A machine according to the invention comprises an upper slide 12 reciprocated by a cam-operated rod 13 and a lower slide 14 similarly reciprocated by a rod 15. A cylindrical plunger 16 is nested in a tubular blank cutting-die 17. The plunger is pinned to a rod 18 adjustably attached to the slide 12 and the die 17 is adjustably connected to the slide 14. The die has its cutting edge on its outer circumference and co-operates with a stationary tubular cutting die 22 supported on a holder 24 on a table 11. Longitudinal adjustment of the die is effected by shims 26. A backing ring 25 inside the holder 24 screws on to a support 27 which passes through the table 11, the support being locked by a ring 28 clamped to the table. Inside the die 22 and located opposite to the die 17 is a spring-loaded tubular ejector 33. Corrugation-forming serrations 38 are located on the die 17 and inside the plunger 16 is a spring-loaded ejector 39. Surrounding the die 17 is a spring-loaded stripper 42. In operation, the slides 12 and 14 are timed so that the plunger 16 and the head 35 grip the work and the die 17 moves into the die 22 so cutting out the blank and drawing the edge of the blank around the head 35 and simultaneously forming the corrugations. In an embodiment a single slide 45, Fig. 4, replaces the slides 12 and 14 and the bore of the rod 18 extends through to the top of the rod where it is closed by a plug 47 against which a spring 41 abuts. The slide operates the die 17 and also the plunger 16 through a resilient connection comprising a pillar 48 on the slide and two bearing plates 49, 50 having a spring 51 between them. Thus, when the work is gripped between the plunger and the head 35 the plunger ceases to move but the die 17 continues its movement and forms the stopper. The serrations 38 may be formed on an extension 52 of the perimeter of the plunger 16, Fig. 5. Alternatively the serrations may be on a detachable surround mounted on the plunger or on a detachable insert 54, Fig. 7, nested in the die 17. Specification 659,200 is referred to.

Title: Improvements in storage batteries
IPC: H01M50/112
Filed: 1928-02-18
Abstract: 285,501. Espagnent, M. Feb. 18, 1927, [Convention date]. Cases; cells; separators; supports for electrodes.-In a portable storage battery in which the plates are separated by vertical ribs 3 within the cell, the ribs are cut away to receive strips 6 of insulating material bearing against the upper edges of the plates 4 to prevent vertical displacement and the plates are drawn upwards against the strips by means bearing on the upper surface of the cell cover to hold it in place. The construction allows ready removal of the plates when required. The plates of each polarity are connected as by welding to corresponding collecting bars b, b<1>, and the strips 6 are held against accidental dislodgment by insulating material such as rubber tubes 7 placed between the upper edges of the plates and the edge of bar b, say at the ends of each strip. As shown, the bar b has a tubular member 9 passing through the cover C and receiving a lead-antimony nut 12 holding the cover in place and connected by connector 13 with a terminal 14 on the cover. Bar b<1> has a rod 9<1> passing through and insulated from the member 9, the upper end having a terminal 16 one member of which is screwed down against an insulating washer 17 bearing on member 9. The cover has a peripheral groove with rubber ring 19 and fits a tapered seating. In modifications, members 9, 9<1> are separated and symmetrically disposed towards the ends of the cell, each having a terminal such as 16, in one such modification the terminals being relied on to hold the cover in place, and in the other the cover being secured by a nut on a centrally placed rod the lower end of which engages an insulating rod passed transversely through aligned perforated lugs formed on the plates.
