Title: Locks
IPC: E05B47/04
Filed: 1975-11-26
Abstract: 1529228 Locks CISA COSTRUZIONI ITALIANE SERRATURE AFFINI SpA 26 Nov 1975 [3 Dec 1974] 48507/75 Heading E2A A lock is formed from a casing 1 through an aperture 9 of which projects a spring latch 10 mounted rotatably on a sliding element 4 so that its axis of rotation is perpendicular to the direction of sliding i.e. of withdrawal of the latch. In ordinary opening of the door &c to which the lock is attached pressure in the direction of arrow A (Fig. 3) would cause the latch to rotate so that face 16 is at an angle to the edge 74 of keeper 72 thus providing a camming surface to force the element 14 into the casing 1 against spring 43 and permit the door to be opened. When the lock is in the locking position however pawl 68 engages recess 71 in the latch and so prevents the rotation and door opening. The pawl is maintained in this blocking position by means of flag 46, the edge 51 of which holds pawl 68 in place. Electrical and mechanical means are provided to remove the blocking and permit the door to open. The electrical means comprises an electromagnet 57 possessing two plungers 60, 61 biased outwards by springs 62, 63 (Fig. 5). When the current is applied the electromagnet attracts plate 54 which in turn attracts flag 46 partly by magnetic force and partly by hooking it by means of hook 55 on its lower edge. This removes flag 46 from the pawl 68 and so permits the door to open. The flag 46 is held in this position, even when the current is switched off, by means of tooth 64 which springs into retaining engagement under the action of spring 65. When the door is opened, however, element 14 slides, carrying flag 46 with it and so bringing the notch 50 on the lower edge of the flag into alignment with the tooth and so freeing the flag so that it can resume, under the urging of plungers 60. 61 the blocking position on later closure of the door. The mechanical means comprises a cylinder lock 42, actuation of which with a key moves element 41 against a side 36 of an angle element 33 (see Fig. 2). This pushes nose 37 against the flag and forces it out of the path of pawl 68 into the same position as before. Means to prevent picking are also provided. This comprises a rotatable plate 77 and a spring loaded rod 82 bearing a cross-pin 81. When the door is closed spring 86 urges plate 77 to a position in which tooth 87 blocks attempted withdrawal of sliding element 14 by picking. When the door is unlocked and opened, pawl 68 engages cam surface 92 and pushes the plate into a position in which the tooth 87 is free of element 14. Spring 85 urges the rod 82 out to the furthest extent, forcing pin 81 against the cam surface 80 to push the nose 91 of the plate out of the path of the pawl which can then return, on closure of the door. without hindrance.

Title: Tufting machines pattern control arrangement
Inventor: ELLISON RONALD
IPC: D03C3/20
Filed: 1964-11-30
Abstract: In a tufting machine in which the file height is varied by a pattern control, the control is synchronised to change the pattern at a predetermined phase of the movement of the needles.  The pattern drum P Figs. 1, 2 (not shown) is scanned by photocells which control via amplifiers 59 brakes 50 acting on the yarns.  A photocell can only energise its amplifier when the synchronising means, which is connected to all the amplifiers, has been activated.  In a preferred embodiment the synchronising pulse is provided by contacts 18 closed by cam 17 rotating with the needle shaft 11.  In modifications a light reflecting spot or magnet on the cam energises a photocell or magnetic pick-up respectively.

Abstract: 1482016 Epitaxial deposition on substrates PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 Nov 1974 [15 Nov 1973] 48965/74 Heading B1S [Also in Division H1] In a method of succesively epitaxially depositing two semi-conductor layers of different conductivty on a semiconductor substrate from a common melt in which an impurity is added to the melt after deposition of the first layer, the substrate 27 (Fig. 1) e.g. of GaP and melt 21 e.g. a saturated solution of Tedoped GaP in Ga are maintained in contact in a crucible on the axis of heater 19 in vessel 13 during said deposition while the impurity e.g. zinc is held, in a container integral with an operating rod extending outside the vessel, remote and radiation shielded from the heater. When the first layer (of N type) is complete container 11 is brought over the crucible and inverted to empty its contents into the melt. In the embodiment shown crucible 10 has movable partitions 14, 15, portion 14 being used to isolate melt and substrate while impurity is added and mixed into the melt and partition 15 to exclude dirt during deposition. All apparatus parts are of quartz. After adding the impurity container 11 is withdrawn to the position shown where it may be supplied with further zinc (or other impurity) 25 by tapping inclined side tube 23a. After deposition of the zinc-doped P type layer partition 14 may be closed and the substrate cooled to room temperature and removed. Alternatively the further zinc may be added to the melt as before and deposition continued to produce a more heavily doped contact layer, to give a structure useful as an LED. A suitable temperature cycle for the deposition process is described.

Abstract: A process for the continuous pre-treatment of a metallurgical charge in a rotary kiln comprises charging ore and carbonaceous reductant to a heated rotary kiln, the charge occupying no more than 15% of the cross-sectional area of the kiln, maintaining a positive pressure of reducing gas at least adjacent to the discharge end of the kiln, injecting sufficient oxygen-containing gas (e.g. air) at a first injection point no more than one-third the length of the kiln from the feed end to effect combustion and consumption of residual reducing gas between the said point and the feed end, the quantities of carbonaceous reductant and reducing gas being such that the total residual carbon content of the partially reduced mixture discharged from the kiln is at least the stoichiometric quantity required for effecting total metallization of the metallic content thereof upon subsequent smelting of the kiln discharge. The temperature and reducing atmosphere within the kiln are preferably controlled such that the component of the charge are reduced without substantial fusion or agglomeration over at least two-thirds of the length of the kiln nearest the discharge end.  The carbonaceous reductant produces hydrocarbons, or hydrocarbons and hydrogen, on heating and additional carbonaceous reductant may be added at a plurality of points between the first position at which the oxygen-containing gas is injected and the discharge end of the kiln.

In a rug cleaning machine through which a rug is conveyed on a backing support at least one massaging roll having radially projecting fingers is movable transversely of its axis parallel to the table of the rug to cause its fingers to knead the nap of the rug, whilst washing solution is supplied in sufficient quantity to wash the massaging roll and the nap being treated thereby. The machine illustrated comprises a pair of massaging rolls 126 mounted on a carriage 118 which is reciprocated horizontally above a table 25 along which rugs are conveyed by endless belts 31. The rugs are fed into the machine by a freely rotating or power driven roll 23 having radially projecting pins 22. Before reaching the massaging rolls 126 the rugs are treated with jets of hot washing solution from nozzles 151, and between the rolls 126 are similarly treated from nozzles 185 which move to and fro with the carriage 118 longitudinally of the rugs and are also reciprocated transversely of the latter. On leaving the massaging rolls 126 the rugs are raised by jets 190 and drawn against a roll 71 before being treated with further rinsing liquid from nozzles 194 reciprocated transversely of the rugs. The rinsing liquid is squeezed from the rugs by resilient rolls 73, 74, and the rugs are finally formed into rolls 21a by a roller 90 having projecting pins 91. The massaging rolls 126 are provided with assemblies of resilient ribbed peripheral rings, the ribs of adjacent rings being out of alignment with each other; and whilst being reciprocated with the carriage 118 the rolls 126 are rotated either by the engagement of pinions thereon with a fixed endless chain or by a driving motor.
