In a two needle sewing machine bottom thread loops are prevented by applying a brake to the shuttle when the corresponding needle is taken out of action during the working of a corner piece. A Bowden cable operated lever has a pivot on which is mounted pivoted lever 31 with a brake shoe 33: as the pivot point moves towards the shuttle during operation one arm of the lever 31 strikes an abutment 34 thus operating the brake. A return spring 35 is provided. To prevent thread breakage in the inoperative shuttle as the operative needle moves beyond the point at which the other needle is taken out of action and into the extreme corner of the work piece the thread leaves the shuttle through a moveable segment 11 which can be moved by the thread 9 against a spring 17. When the operative needle again returns, after the corner is turned to the appropriate point adjacent the inoperative needle the spring 17 pulls back the thread 9 by the segment 11 and the inoperative needle is restarted.

Title: Fluid apparatus
IPC: G01B13/10
Filed: 1965-06-24
Abstract: 1,111,717. Fluid sorting devices. BENDIX CORPORATION. 24 June, 1965 [25 June, 1964], No. 26848/65. Heading G4P. [Also in Divisions Gland G3] The fluid pressure in a line 14, which is dependent on the internal diameter 25 of a workpiece such as an annular ring 26 is used for controlling a bi-stable device 16, to indicate that the workpiece is oversize, acceptable or undersize. If the workpiece is too large, that is the pressure in line 14 is small, the bi-stable device 16 is not switched by the flow from channel 15 and so an output is obtained along channel 28 to switch two further bi-stable devices 32, 33 to give output along channel 62, 63 respectively. Since there is no flow along channel 64, a valve device 39 is not operated by the flow from channel 63 and so the only signal passed is to read-in memory 46 which provides a signal to ejector device 85 as the workpiece passes station 87 to eject it. If the workpiece is of the correct size a portion of the flow from channel 28 is deflected into channel 27 but the flow remaining in channel 28 is not sufficient to deflect the bi-stable device 32 so that flow continues through channel 64. The flow from channel 28 to channel 61 however is sufficient to deflect the bi-stable device 33 and since there is thus flow on both the inputs to valve member 39 a signal is passed to read-in member 47. This signal is successively passed to members 56, 76, 90, 95 so that when the workpiece reaches station 103 a signal to the ejector member 102 ensures that it is ejected at this station. In a similar manner if the workpiece is undersize it is ejected when it reaches the station 113.

Valves controlled from a distance. - A distributing system for the supply of gas to burners for street lighting has n groups of apparatus all of which are opened by increasing the pressure from a minimum to a normal working value, while the first n-1 groups are closed successively by a series of pressure waves the first wave closing the first group leaving the other groups unaltered, the second wave closing the second group and so on, the nth group being closed not by a pressure wave but by reducing the pressure to the minimum. Fig. 5 shows a form of apparatus for use on the first of the first n-1 groups and comprises a rotary disc valve 11<a> having a series of ports adapted to co-operate with a port 15a in a fixed seat and operated by a ratchet wheel 10 having a series of large teeth 10<a1> equal in number to the number of ports 12<a2>. The ratchet wheel is actuated by a pawl 9<a> pivoted to a diaphragm actuated by gas pressure against the action of an adjustable spring 5 and is arranged so that increasing the pressure from the minimum to the working pressure rotates the ratchet wheel half a tooth. Fig. 6 shows a form of valve and ratchet wheel for use on apparatus of the second group, here the large teeth are separated by small teeth and the port 15<b> is elongated so that the disc may be rotated through an angle equal to one small tooth without closing the valve when once opened. The apparatus in the third group has the large teeth separated by two small teeth and so on. By dividing the outlet chamber into two or more compartments each having a separate port in the fixed seat a single valve may be arranged to control two or more groups. The magnitude of the successive pressure waves may differ from each other and may be negative in sign.

Filed: 1948-10-21
Abstract: 690,212. Methods of physical development. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Oct. 21, 1948 [Oct. 24, 1947], No. 27357/48. Class 98 (ii). A process for producing metal images in exposed photographic material by physical development, in which the whole of the material to be developed is introduced to the developer at the same time and later is removed therefrom at the same time, comprises supplying a quantity of developer stabilized against decomposition to the exposed material, removing the material from the developer or the source of supply of developer from the material, and thereafter allowing development to proceed while heating the material and the developer applied thereto. The developer may be stabilized by cooling, dilution or acidifying to pH less than 1. The photographic material may have developer applied to it by impregnating, dipping, spraying or sprinkling and development effected by heating with steam, hot air, infra-red radiation, hot water, or by application to a hot plate or drum. Thus a regenerated cellulose film is sensitized with 1-hydroxy 2- diazonium 6-methyl benzene 4-sulphonic acid, mercurous nitrate and nitric acid, dried, exposed, and wound helically on to a drum which is then rotated in a bath of developer, the drum then being removed and steam passed into its interior to accelerate development, the film thereafter being washed with boiling water and then aqueous glycerol. The developer bath may contain either a metol-silver nitrate developer stabilized with nitric acid or a hydroquinone-tartaric acid-silver nitrate developer, to which glycerol is added to prevent freezing, stabilized by cooling to - 6 ‹ C. A paper support similarly sensitized is developed in a similar manner, heating being achieved by means of steam or on a print glazing drum. Alternatively there may be used a hydro. quinone-silver nitrate developer stabilized by dilution, more especially by lowering the concentration of the reducing agent. Specifications 439,005. and 545,901 are referred to.
