Abstract: 1,197,355. Retractive switches. LA TELEMECANIQUE ELECTRIQUE. 27 June, 1968 [30 June, 1967], No. 30802/68. Heading H1N. A pushbutton switch comprises a fixed contact 9 and a movable contact 7 on the end of bent strip 3 the free end of which is gripped between extensions 8a or arm 8 of intermediate element 1 pivoted at 2 and having a second arm 14 actuated by dog 11 on extension 12 of the pushbutton. Spring 17 urges the free end of strip 3 towards the fixed contact but movement is prevented by dog 11 engaging surface 15 of arm 14. When the pushbutton is depressed, extension 12 and dog 11 move downwards and arm 14 is freed and the contacts are closed. When the pushbutton is released a retractive spring urges it upwards so that dog 11 engages cam surface 16 of arm 14 and cams it back to its original position breaking the contacts. Surfaces 15 and 16 on the end of arm 14 may be arranged, Figs. 4, 7, 8 (not shown), so that the contacts are normally closed and when dog 11 moves downwards it engages cam surface 16 and opens the contacts. There may be two sets of contacts each with its element 1 on each side of centrally disposed extension 12. A number of pushbutton units may be mounted in control panel, Fig. 10 (not shown), each secured by a ratchet spring 22, Fig. 1 (not shown). A signal lamp is provided within the pushbutton.

Title: Improvements in and relating to machines for sorting articles according to weight
IPC: B07C5/20
Filed: 1932-11-03
Abstract: 409,722. Sorting bodies by weight. POINTON, J. E., HARBER, L. S., Westwood Works, Peterborough, and BAKER PERKINS, Ltd., Hythe Road, London. Nov. 3, 1932, No. 31062. [Class 143.] Apparatus for classifying articles of a plastic nature, such as dough, according to weight, comprises means for checking the weight of an article including a scale pan, and means adapted to engage and apply a rolling propulsion to the article, for removing it from the scale pan to the classifying means. Pieces of dough are delivered down a shoot or by a band conveyer or other mechanical feed upon a scale pan 10 covered with fabric or dusted with flour and locked by catch device 18 and detent 17. A piece of dough on the scale pan 10 closes the sensitive contacts 11, 12 through the contact maker 13, to actuate the electromagnet 27 to pull the trigger 26 out of engagement with the heel 28 of the pawl 25 which is then spring pressed into engagement with the ratchet wheel 22 fixed to the constantly rotating shaft 21. The pawl 25 is carried by a cam 23 or a lever associated therewith, the cam 23 and a cam 24 integral therewith being loosely rotatable on the shaft 21. The cam 24 during its rotation raises the locking catch 18 through the spring- controlled lever 48 and releases the scale pan 10 which is balanced through a known arrangement of levers and linkages 14 by a predetermined loose or adjustable counterpoise 15. If the piece of dough is underweight the pan 10 rises and with it the vertical spindle 16 to break the contacts 19, 20 to de-energize the electromagnet 41 to cause the spring 42 to disengage the trigger 39 from the detent 40 to allow the spring 43, through the link 44, to move the flap 37 or shoot to the left in Fig. 1. The flap 37 is reset through the link 44 coupling it to the bell crank lever 45, 45<a>, moved by the extension 30 of the pivot of the pawl 25 near the end of a revolution. Movement of flap 37 to left is limited by the engagement of a projection 46 on the bell crank lever 45 with a stop 47 on the latch lever 29. The cam 23 during its rotation engages with rollers on bell crank levers 35, 36 to rotate arms 31 carrying a fluted roller 32 having a gear wheel 33 engaging with a stationary arcuate rack 34 to rotate the roller 32 and remove the dough by an upward rolling action, the dough taking one path or another according to the position of the flap 37. The discharge arms 31 may be spring-actuated in one direction and cam-actuated in the other. The apparatus may be modified to detect both light and over-weight pieces, the spindle 16 being provided with a contact maker sliding over a fixed contact so that a break in the circuit would be effected and the flap 37 actuated should the spindle rise or drop corresponding to the light or over-weight pieces.

Abstract: 328,636. Dreyfus, H. Oct. 29, 1928. Grant of Patent opposed. Cellulose esters and ethers, processes for making filaments and films from.-By employing acetone solutions of cellulose acetate or other esters or ethers of cellulose containing such a proportion of water that the viscosity of the solution is substantially reduced as compared with that of a solution of the cellulose derivative in commercial acetone, the filaments obtained by the extrusion of such solutions may be drawn out to give products of exceptionally fine denier, for example, to below 3 deniers down to one denier or even less, or thin films or ribbons mav be similarly produced. The products possess high tensile strength. It is preferred to employ solutions of minimum viscosity, preferably such as contain. 10-12 per cent of water. The acetone may be in part replaced by other solvents of lower or higher boiling point, for example, diacetone alcohol; or it may be replaced by an organic diluent such as ethyl alcohol.
