Patent GB-1377127-A (GB)
Title: Charge coupled circuits
IPC: G11C19/28
Filed: 1972-01-05
Abstract: 1377127 Charge coupled devices RCA CORPORATION 5 Jan 1972 [14 Jan 1971] 20044/74 Divided out of 1377121 Heading H1K The input to a charge coupled device comprises a source region and a control electrode which are pulsed concurrently with the supply to a first storage electrode to inject charge carriers into the potential well produced under the first storage electrode. As shown, Fig. 5, the source S1 is given a bias of -15V on which may be selectively superimposed a positive going 10V pulse. The control electrode 14-0 is connected to a negative going 10V pulse supply and the electrode 14-1 is the first storage electrode of the register and is connected to a first phase of a multipled phase power supply. The pulses applied to the source S1 and control electrode 14-0 are timed to occur within the #1 pulses applied to electrode 14-1 and overlap to a large extent but with the control electrode pulse V c  starting and stopping before the corresponding edges of the source pulse. When the source pulse is present the source potential rises to -5V and the control electrode pulse opens a channel between the source and the potential well generated by the #1 pulse under electrode 14-1. This potential well is therefore partially filled with minority carrier (holes) until its effective potential equals that of the source S1. The termination of the control electrode pulse before the source pulse closes the channel so that the injected charge is stored under the electrode 14-1. If the source voltage pulse is absent however the source remains at -15V and no charges can be injected even when the control pulse is applied, the source in fact acting as a "drain" to remove any residual charge from the potential well. The Specification also includes a description of a charge injection arrangement in which the source is not pulsed, see abridgement of the parent application.

Title: Improvements in or relating to machines suitable for use in the manufacture of shoes
IPC: A43D3/02
Filed: 1956-06-29
Abstract: 863,784. Moulding soles on to footwear uppers. BRITISH UNITED SHOE MACHINERY CO. Ltd., and FRAMPTON, S. E. June 28, 1957 [June 29, 1956], No. 20130/56. Class 87(2). A machine for moulding soles on to footwear uppers comprises a two-part foot 19 on which a footwear upper may be placed, a holder 12 for the foot with which the latter may be moved bodily from a loading position to an operative position in which a sole may be moulded to the upper, locking means 44 arranged to lock a movable heel part 62 of the foot against movement from a position in which it is in alignment with the other part 20 of the foot correctly to define the shape of the foot, and an operator-actuatable member 38 arranged, on actuation, to unlock the heel part 62 and then foreshorten the foot 19 by moving the heel part 62 relatively to the other part 20 of the foot. In the machine illustrated for moulding and vulcanising rubber soles to shoes, the foot 19 is secured to a support block 18 which is set in a dovetailed slot in the base of a block 2, carried by a supporting member 102, which also has a channel extending longitudinally in which is adjustably mounted a member 26. One arm 36 of a bell crank lever 34, which is pivoted at its elbow between forward end portions of the member 26, extends rearwardly between the walls of this member and is pivotally connected to a link 40 which at its rearward end is pivotally and loosely connected to and between the arms of a fork 42 forming the forward portion of the locking member 44. When in operative position, this locking member wedges against the upper cross face of the channel in block 2. Lever plates 52 set on either side of the locking member 44 are pivoted on pins 54 to the walls of member 26. The movable heel part 62 of the foot is connected by rod 60 through pin 58 engaging slots 56 to the pivoted member provided by lever plates 52, rocking movement of which brings about endwise movement of the rod and causes the movable part 62 to slide on part 20. Furthermore the lever plates 52 engage by means of rolls 48 and slots 50 with the locking member 44 which is coupled, by means of a toggle formed by arm 36 and link 40 to the operator-actuatable member provided by the handle 38. In order to remove a shoe from the foot 19 after vulcanisation, piston means move the foot to the loading position on supporting member 102 and handle 38 is moved upwardly so as to break the toggle formed by arm 36 and link 40. This movement of link 40 causes the locking member 44 to move out of wedging engagement with the block 2 and further upward movement of the handle 38 causes the lever plates 52 to be swung about their pivot points 54 and, by reason of slots 56 engaging the pin 58, the arm 60 and hence also the heel part 62 move upwardly so as to allow the finished shoe to be removed from the foot 19. Specification 859,671 is referred to.

Title: Process for the manufacture of fashioned articles from fabrics containing artificial filaments, threads, straws and the like
IPC: D06M11/05
Filed: 1934-07-10
Abstract: Fashioned articles of wearing-apparel, e.g. brassieres, suspensories, hats, hat shapes, caps, and girdles are made from a fabric of an organic derivative of cellulose free from plasticizer, by fashioning the fabric by distortion of the filaments of the fabric while they are in a heat-softened state. The fabric may be woven, knitted, or netted from filaments, bristles, or straws made of an organic cellulose ester or ether. The flat fabric may be placed between the members of mould-like devices of the desired shape which are heated by steam, electricity, flame, or the like.  In the case of a fabric made of cellulose acetate, a temperature of 125 to 180 DEG  C. may be employed, but by using temperatures of above 180 DEG  C. a stiffened article is obtained due to coalescence of the filaments.  When steam or water is present during the shaping operation, p  temperatures of about 100 DEG  C. are sufficient.  If a stiffened product is required, the shaped article may be treated either with a solvent which will cause coalescence of the filaments, e.g. acetone, methyl acetate, and dioxane; with a solution of a cellulose derivative in a liquid which may or may not have a solvent action on the filaments of the shaped article; or with solutions of dammar, copal, elemi, or other resin, or gelatine.

Patent GB-456547-A (GB)
Title: Improvements relating to the conversion of ethers to alcohols
IPC: C07C29/10
Filed: 1935-07-22
Abstract: Ethers are converted to alcohols by hydration with a dilute aqueous acid catalyst such as sulphuric, phosphoric, hydrochloric or, less advantageously an organic acid such as acetic acid, or alternatively an acidic salt such as zinc or aluminium chloride at elevated temperature and pressure such that the bulk of the alcohol formed is retained in the liquid phase and preventing substantial increase in the concentration of the acid.  The activity of the catalyst may be increased by adding other substances such as silver salts, or oily substances such as fatty or mineral oils or turkey red oil.  Ether entering at 1, Fig. 1, is forced by a pump <PICT:0456547/IV/1> <PICT:0456547/IV/2> 2 through a heater 3 and steam may be added at 4. The vapour enters a packed tower 6 having a heating-jacket 9 and acid liquor is introduced at 7.  Any olefine formed is withdrawn by a pipe 10 and passed through a condenser 11 to recover ether which separates from the water in a vessel 13.  Acid liquor containing alcohol is withdrawn by a pipe 17 through a pressure-reducing valve 18 to a distilling column 19 having a cooling-coil 21 at the top, alcohol vapour containing some ether being drawn off at 22 to a column 23 for separation.  In a modification, Fig. 2, the ether vapour meets sprayed acid liquor in an unpacked reaction vessel 106 having spraying nozzles 107.  The temperature may be 200--300 DEG  C.  Some production of olefine may occur at 250 DEG  C. and increases at higher temperatures; this may be checked by adding steam.  The pressure may be 225--3000 lb.  In the examples, sulphuric acid of 10 per cent and 5 per cent strength is used.  The Specification as open to inspection under Sect. 91 states that the reaction temperature may be as low as 20 DEG  C.  This subject-matter does not appear in the Specification as accepted.
