Patent GB-226167-A (GB)
Title: Improvements in or relating to stencil sheets
IPC: B41N1/24
Filed: 1924-09-30
Abstract: A coating-composition for stencil sheets comprises viscose which is prepared by soaking cotton in caustic soda or other alkaline solution for twenty-four hours, expelling surplus moisture, standing the cotton in a closed vessel for forty-eight hours, adding carbon-bisulphide, stirring for four hours and then adding caustic soda solution.  The mass is now dissolved in water and is wholly or partly neutralized by the addition of an organic acid such as malic, butyric or malonic acid.  The sheet is drawn over the viscose solution, dried and then drawn over a solution which includes a coagulating agent such as formaldehyde and a tempering-agent such as glycerine or a sulphonated oil.  Reference has been directed by the Comptroller to Specification 216,307, [Class 100 (ii), Printing processes &c.].

Title: Improvements in or relating to spinning and twisting frames
IPC: B65H63/08
Filed: 1926-09-20
Abstract: 277,496. Smith, W. Prince-, and Lumby, L. Sept. 20, 1926. Stop-motions; stop-apparatus, non-automatic.- In spinning, twisting, and like frames the starting-rod A is engaged while the frame is running by a catch B, which is coupled to a member of the knock-off motion E by a flexible connection, such as a Bowden wire, so as to be released thereby and to permit the starting-rod to move by the action of a spring A<2> to shift the driving-belt or otherwise to stop the frame. The catch B is mounted on a bracket C carried by a finely threaded rod D, and in order to start the frame, the rod is operated by a hand-wheel D<3>, so that the bracket C is advanced to engage the catch with a hook A<8> on the starting-rod and is. then retracted to the position shown. The knock-off motion, which may be of the " spooltype " or " length-type," on each side of the machine is connected to the catch, and each motion may operate independently of the setting of the other. The catch and the starting-rod remain in engagement until the bobbins are full, and during the intervening period, such as at meal times, the frame may be stopped and restarted in the ordinary manner. Instead of the starting-rod being engaged by the catch R to effect the starting of the frame, a lug may be fitted to a sliding member operated by the screw and adapted to engage a collar or abutment on the starting-rod.

Title: Improvements in the production of dough
Inventor: ROLLETT ANTHONY VICTOR
IPC: G05D24/02
Filed: 1965-08-04
Abstract: The supply of one of the ingredients to a dough mixer is automatically controlled in dependence on the consistency of the dough to maintain the consistency at a desired value.  In one arrangement, flour and water are mixed to form dough in batches and each batch is mixed until the mixer has used a given quantity of electrical energy.  The times taken to mix each batch are measured and stored in a digital computer which continuously averages the last eight batch times and determines the additional amount of water supplied to the next batch so as to correct consistency variations. A time corresponding to the desired consistency is set into the computer and actual times are compared by back counting.  A modification is referred to in which the amount of water is modified if a predetermined number of mixing times in a group vary by more than a predetermined amount from a preset time.  The power, current or torque of the mixing motor may alternatively be used as a measure of consistency.
