Title: Improvements in Methods and Apparatus for Making Bread.
Inventor: JACKEL SIMON SAMUEL
IPC: A21C1/00
Filed: 1968-03-15
Abstract: 1,182,221. Bread. S. S. JACKEL. 15 March, 1968, No. 12687/68. Heading A2B. In the manufacture of bread by the continuous mix process, wherein the bread ingredients, including a liquid ferment, are blended in a premixing zone to form a premixed dough lacking effective development, which premixed dough is thereafter subjected to continuous working to provide a developed dough having greater gas cell retention properties than the premixed dough, at least a part of the premixed dough is subjected to ultra sonic vibrations prior to the developing step. Thus, the premixed dough may be forced through a nozzle, which is preferably in the form of a slit, under pressure to form a stream of dough, which impinges on a vibratory element, for example in the form of a flat blade having its free edge directed towards the nozzle whereby the dough stream passed to both sides of the blade, thereby setting up ultrasonic vibrations in the element, which are in turn transmitted to the dough stream.

Title: Drilling apparatus
IPC: B23B49/06
Filed: 1957-04-24
Abstract: 819,980. Drilling-machine details. BENDIX AVIATION CORPORATION. April 24,1957 [May 28, 1956], No. 13087/57. Class 83 (3). A machine for drilling, tapping, &c., arcuate linings, e.g. brake linings 57, comprises a rotatable drum 12 supporting the linings during drilling, and a locking pin 78, Fig. 7, operated automatically to hold the drum in predetermined positions during the drilling operations. The linings 57, stacked in a shoot 13, are released singly by a dispensing apparatus 14 beneath the shoot, and are gravity-fed into recesses 22, formed by replaceable spacers 28 on the periphery of the drum, in which they are held by the roller 68 on a pin 64 spring-pressed towards the drum. A pneumatic cylinder 63 retracts the roller during delivery of a liner, and is controlled by micro-switches 36, 38 which also control a pneumatic cylinder 40, Fig. 4, for operating the dispensing apparatus. The switches are operated by a pair of lugs 32, 34 mounted on the drum-rotating shaft 24, which is driven through a friction clutch 26 by a sprocket 27. A handle 66 adjusts the radial setting of the roller 68. Operation.-The drum is stopped, with one of its two diametrically opposite recesses 22 in position to receive a liner, by the pin 78, which is operated by a pneumatic cylinder 80 acting against the pressure of springs 79. The springs withdraw the pin from an index hole 76 in the bottom of the drum when a timer (not shown) interrupts the supply to the cylinder 80, thus enabling the clutch to recommence rotation of the drum and carry the liner past a drill-head traversed by power means 86 and having a pair of drills 88, the distance between which may be adjusted. The drum is stopped in the drilling positions by further index holes 76, from which the pin is again withdrawn under control of the timer, which preferably also controls movements of the drill-head. Some of the holes 76 may be plugged to vary the drilling pattern. Springs 72, on posts 74 adjacent the drills, press the liner against the drum as it approaches the drills and storage shoot 18, on to which it is released with the drum in position to receive a further liner from the dispensing apparatus. Dispensing apparatus.-The stack of liners is normally held by the leading stop 54 of a pair of stops 54, 56 disposed one behind the other in the direction of advance of the stack. The stops are mounted respectively on levers 50, 52 operated by links 46, 48 connected one to each side of a pivot 44 for a lever 42 operated by the cylinder 40. Thus, upon operation of the cylinder to release a liner, the leading stop 54 is lowered, releasing the leading liner, and the trailing stop 56 is raised, preventing escape of the rest of the stack. Upon a return operation of the cylinder, under the control of a timer, the stop 54 is again raised and stop 56 lowered, causing the stack to move forward against stop 54,

IPC: G01C3/12
Abstract: 135,223. Barr & Stroud, Barr, A., and Stroud, W. Oct. 30, 1916. Range-finders.-In single-observer range-finders comprising a double telescope supported within a comparatively long outer tube carrying doubly reflecting prisms or mirrors at each end, an extra telescope for coincidence instruments, and one or two extra telescopes for stereoscopic instruments, are provided so as to present to the observer one or more large fields of view surrounding or adjacent to the small fields of view presented by the double telescope. Fig. 8 shows, in plan, a coincidence range-finder having a third objective 20 the rays from which are deflected upwardly and then horizontally by a prism system 22 to a prism 23 by which they are deflected downwardly into the eyepiece prism system. Various eyepiece prisms systems may be employed. In the system shown in Fig. 4, which is applicable to the construction of range-finder shown in Fig. 8, the central ray from the right-hand end of the instrument is reflected by the hypotenuse of the prism 8 on to the face 15; it then strikes the silvered upper half of the hypotenuse of the prism 13 and is reflected through the prisms 5, 6 to the eyepiece 3. The central ray from the left-hand end is reflected by the hypotenuse of the prism 9 through the lower half of the prism 13 to the eyepiece. This system may be modified by the substitution of a rhomboidal prism for the prisms 5 and 13. Fig. 2 shows an eyepiece prism system similar to that shown in Fig. 21<b> of Specification 1462/03. The central ray R from the right-hand end of the instrument is deflected downwardly by a double reflecting-prism before entering the prism 8, and it is then reflected as indicated to the upper face of a biprism 5. The central ray L from the left-hand end enters the prism 9 and is reflected as indicated to the lower face of the biprism 5. In the system shown in Fig. 3, the rays entering the prisms 8, 9 are reflected by the surfaces 12, 10 respectively through the prisms 5, 6. In each of these systems, the rays from the extra telescope pass normally through the face 7 into the prism 6 and are reflected by its hypotenuse so as to present a field of view surrounding the small fields, the image being formed in the plane of the separating-line 1. In stereoscopic range-finders, an extra telescope may be provided for one or each eye, and the. eyepiece prism systems may be suitably modified.

Abstract: 623,716. Protective cut-out arrangements; actuation of switches. SMITH & SONS (ENGLAND), Ltd., S., and MEREDITH, F. W. May 20, 1947, No. 13576. [Class 38(v)] Polyphase apparatus 11, such as the automatic pilot of Specification 611,037, is protected against fault by means of a switch comprising a torque motor, such as that described in Specifications 576,248 and 576,249. Under normal conditions the motor torque balances the restraining torque of a spring 7, which upon failure of one phase, due e.g. to the blowing of a fuse 14, and the consequent reduction of the motor torque, causes an arm 4 to rotate and open contacts 6 in the circuit of contactor 15. Similarly, contacts 6 are opened with low voltage conditions or incorrect phase rotation. If, however, the voltage is too high, the motor torque will overcome the restraining torque to open contacts 5. The motor shaft may be damped by a cup operating between a permanent magnet and a yoke ring (Fig. 3 not shown).
