Abstract: 1,242,144. Shirring sausage casings. KALLE A.G. 23 Dec., 1968 [27 Dec., 1967], No. 61047/68. Addition to 1,131,880. Heading A2B. In the shirring of artificial sausage casings wherein one end of the casing is passed over a mandrel to a stop and the casing is subjected to internal gas pressure during advancement of the casing on the mandrel towards the stop with concomitant compression and creasing of the casing against the stop, the force causing this compression is applied at two or more locations on the casing by means of the grooved rims of wheels, which wheels are simultaneously oscillatable about the axis of the mandrel. A suitable apparatus for the method of the invention is shown in Fig. 1 wherein a sausage casing in the form of an inflated tube 4 is passed over a mandrel 9. The tube is pressed against a stop 8 by rotating wheels 6, thus pleating the tube. The wheels are mounted in such a way that they are oscillatable about the axis of the mandrel (Fig. 2, not shown) thus achieving a more uniform distribution of pleats.

Abstract: 636,649. Electrically - actuated valves. RADIATION, Ltd., BRATT, L. A., and SEALEY, S. Dec. 22, 1947, No. 33767. [Class 135] A solenoid-operated valve for controlling the gas supply to main and pilot burners comprises a casing a with an inlet b, a main outlet d controlled by a main valve member f, and a pilot outlet c controlled by a pilot valve member h. The pilot -valve stem, which has a lost-motion connection with the main valve member, is carried by an armature m and extends through a floating armature p. When the winding n is energized, the armature m rises into contact with the armature p and opens the pilot valve. If the winding o is now energized, both armatures rise together and open the main valve, and both armatures will be retained in the raised position on the subsequent de-energization of the winding n. Should winding o be energized first, the armature p rises but only pushes up a loose washer s and both valves remain closed. Circuits containing the windings and an electric ignition device for the pilot burner may be controlled by a switch actuated by a bi-metal strip in the path of the pilot flame.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 7, 1947.] Drawings to Specification. Class 106 (i). A machine for effecting automatic short-cut multiplication comprises means for storing the multiplier, means for sensing in turn the denominations of this storer, mechanism controlled by the sensing means for causing the repeated entry of the multiplicand, the mechanism being such that when the multiplier digit sensed is, e.g., 6 ... 9, the multiplicand is subtracted 3 ... 1 times and the value of the multiplier digit in the next higher denomination is increased by 1. When the multiplier digit is, e.g., 1 ... 5, the mechanism causes the multiplicand to be added 1 ... 5 times, there being no alteration to the next higher multiplier digit. This is in " positive" multiplication. In " negative " multiplication, multiplier digits 1 ... 5 cause the multiplicand to be subtracted a corresponding number of times, and digits 6 ... 9 cause it to be added 3 ... 1 times and the next higher multiplier digit to be increased by 1. The machine described is the same as that disclosed in Specification 674,827. Specifications 413,205, 551,311, 582,052 and 582,223 also are referred to.

Patent GB-750128-A (GB)
Abstract: 750,128. Grinding. JONES & SHIPMAN, Ltd., A. A., and HOULDSWORTH, J. July 9, 1953 [April 10, 1952], No 9247/52. Class 60 [Also in Group XXIX] In a grinding machine, means for controlling the feed of the tool or wheel into the work comprises a disc 1 rotatable in response to the forward feed; the disc 1 carries a dog 2 adjustable along an arcuate slot 2<SP>1</SP> or alternatively secured in a selected hole of a series. At a predetermined stage of the feed the dog 2 contacts the nose of a spring-locked lever 6 thus closing switch 7 and energizing relay SCR; this closes switches SCR1 and SCR2, the former completing a holding circuit for relay SCR, and the latter energizing a solenoid 10 which moves a valve 11, against the action of a spring 12, so that exhaust fluid from the feeding mechanism normally flowing through throttle valve 16 is diverted through throttle valve 17, both valves being adjustable. The rate of feed is thus varied e.g. reduced. Just prior to the engagement of a stop projection 4 on the disc 1 with a dead stop 5 to terminate the feed, the nose of the lever 6 enters a notch 3 in the disc 1, causing closure of switch 8 to supply current to a timing unit 34. This energizes a coil 35 which sets in motion a time delay mechanism, settable by the operator, to determine the length of time desired to elapse before further action takes place. On completion of the delay period a switch 36 is closed so that solenoid. 21 is energized; this disengages a catch 19 on the solenoid core from a lever arm 18 which, under the action of a spring 24, rotates to open a switch 20 through which the control circuit is fed. Release of the lever arm 18 also causes, through the resultant rotation of its shaft 18a, operation of a reversing valve so as to reverse the feed, and also through rod 23 interrupts traverse of the wheel longitudinally across the work.
