Abstract: 1,261,204. Pure fluid oscillation. NATIONAL RESEARCH DEVELOPMENT CORP. Feb.20, 1969 [Jan. 24, 1968], No.3818/68. Heading G3H. [Also in Division G4] Fluid from an inlet port 13 Fig. 1 passes to one of two-or more outlet ports 15, 16, under the control of fluid from one or more control ports 20, 21, by attachment to a wall 17, 18 of chamber 11. In the embodiment of figure 1, with flow initially through port 15, control signal at port 20 results in a build-up of pressure in region 24 so that the fluid attaches itself to wall 18 and the output switches to port 16. Further control signals at port 20 have no effect but a signal at port 21 switches the flow back to port 15. In a modification Fig. 2 (not shown) a single control port (25) controls the switching, a continuously applied control stream producing free running oscillation, discrete control pulses producing switching between the outlet ports (15, 16).

Abstract: 455,085. Television. LUBSZYNSKI, H. G., 36, Cherry Grove, West Drayton Road, Hillingdon, and RODDA, S., 170, Ladysmith Road, Enfield, both in Middlesex. Feb. 9, 1935, No. 4237. Addition to 442,666. [Classes 39 (i) and 40 (iii)] An object is imaged on a photo-electric screen 1 to produce electrons which are accelerated towards and focused, e.g. by a solenoid 2, upon a mosaic electrode 4 to produce an electron image upon the electrode 4 making each element thereon more negative. The mosaic 4 is scanned by a cathode ray beam from a source 7 which is at such a potential that secondary electrons are emitted from each element of the mosaic in turn in sufficient numbers to make each element more positive and to bring each element to an equilibrium potential at which the emission of secondary electrons is equal to the reception of primary electrons. The change of potential so produced is transferred through the condenser formed by the element and the signal plate 5 to the grid of a valve 10 and forms the picture signal. A similar arrangement is described in which the mosaic is scanned on the side opposite to that on which the photoelectrons impinge, Fig. 3 (not shown). Secondary electrons emitted as the result of the photoelectrons may be repelled back to the mosaic by a further electrode at a suitable negative potential.

Title: Improvements in delayed-break electrical contactors for vehicle direction indicators
IPC: B60Q1/34
Filed: 1960-02-08
Abstract: 885,555. Road traffic signals on vehicles. ETABLISSEMENTS ED. JAEGER. Feb. 8, 1960 [Feb. 9, 1959], No. 4431/60. Class 118. An electric switch having a delayed breaking action and suitable for the control of vehicle direction indicators, is combined with a contactmaking mechanism the breaking of which is determined by the travel of a vehicle over a predetermined distance. Operation of the control lever 1 (Fig. 1) to right or left completes a circuit through contacts 5, 7 or 4, 6, respectively, for relay 9, operation of which closes contacts 28, 29 to extend battery via flasher unit 23 to the indicator lamps (not shown). Operation of lever 1 also rotates the arm 12 anticlockwise about the pivot 13 thus closing the contacts 18, 20 between the bi-metal strip 16 and the resilient strip 21 to complete a second circuit to the flasher 23 and the lamps. A tooth 15 on the end of the arm 12 engages in a hole 17 in the bimetal strip serving as a latch to prevent the strip springing back to its rest position. Current also flows via the contacts 20, 18 and the arm 12 to the heating coil 19 of the bi-metal strip 16 and the resulting heating bends strip 16 towards strip 21. After an interval the tooth 15 disengages from the hole 17 and the bar 12 is returned by the spring 14 to its normal position. The strip 16 cools and eventually the strip 21 meets the stop 22 and the contacts 18, 20 are opened. In the meantime operation of the relay 9 raised the armature 26 thus disengaging the catch 31 from the notch 32a of the wheel 32. This wheel 32 is loosely mounted on the spindle 33 (Fig. 3), which is a part of the vehicle mileage counter, between a washer 34 keyed on the spindle 33 and urged to the left, by spring 35 acting against washer 36 and spacer 37, into frictional contact with the member 136 which is keyed on the spindle 33, and bears at its centre against a central boss of a bearing block 38. A disc 40 is interposed on the boss of block 38 and is applied against a toothed disc 41. The disc 40 has an axially extending projection 42 passing through apertures 43 and 44 in disc 41 and wheel 32, respectively, the end of which is urged anticlockwise by the spring 45 wound round the spacer 37 and anchored to the bolt 46 on wheel 32. Hence, when the armature 26 is raised a tooth 41a (Fig. 1) of the disc 41 is moved by the spring 45 to close the notch 32a, the catch 31 being supported on the head of tooth 41a to maintain contacts 29, 30 closed. The current supply to the flasher 23 is thus maintained after the lever 1 returns to its neutral position and after contacts 18, 20 are opened. When the vehicle moves forward the wheel 32 and disc 41 are driven anticlockwise the contacts 29, 30 remaining closed until the catch 31 encounters the front edge of the next tooth on disc 41, whereupon the spring 45 is re-tensioned and the catch 31 drops into the next notch 32a in wheel 32, thus opening contacts 29, 30.

[Class 128] A stand 1 for teapots, jugs, bottles and the like formed of heat resisting material such as an artificial resin to which is applied a piece of felt or other liquid-absorbing material 2 has attached at diametrically opposite points flexible members adapted either to be passed over the top of the vessel to retain a lid if necessary, to be hooked to the open edge of the vessel or to be attached to the neck of the vessel by a ring. As shown each holder, which consists of a small piece of chain connected to a piece of elastic material and covered with a flexible sleeve 3, is secured by a hook 8 at one end to the stand. The free ends are connected together by two pieces of elastic material 4 adapted to be passed round the knob of the lid. The connections 4 may be replaced by hooks adapted to engage over the rim of a jug or by a felt-padded ring to be passed over the neck of a bottle. Hooks 8 and the length of chain may be dispensed with, the holders being entirely of flexible elastic material attached directly to the stand.

Abstract: 1496425 Peeling and mashing potato PILLSBURY CO 3 Feb 1975 4484/75 Heading A4C [Also in Division H2] A process of preparing a dehydrated potato product comprises cutting the potatoes into pieces that are not more than an inch in thickness, blanching the cut potatoes to swell the starch granules without softening the potato, exposing the potato to a cortex discoloration inhibiting agent after mashing the potato, cooling the  potato to a temperature of not more than 100‹F, exposing the potato to sufficient heat to cook it to a mash consistency, placing the cooked potato having peel on it between pressing elements, at least one of the elements having openings therein whereby cooked portions other than the peel of the potato are forced through the openings therein, severing the peel from the cooked portions whilst returning the peel on the surfaces of the pressing elements and thereafter drying the mashed potato by exposing the mash to a drying medium to obtain a non-pasty dehydrated potato. Preferably the pressing elements comprise a pair of parallel pressing drums having openings through them and being mounted adjacent to one another, said drums being rotated upon their longitudinal control axes in opposite directions whereby successive portions of the drum converge toward one another. The peeling step of the above process may be carried out in the apparatus shown in Fig. 4 wherein the cooked potato pieces are placed between the  rotating drums 20, 22 and the cooked portions of potato are squeezed through the openings in the drums and augered by auger flights 34 and 36 to the collecting shoots 42 and 44. The peel is further pressed by drum 62 to remove any residual edible material that clings to peel 78 that has accumulated on drum 20 and to peel that is removed from drum 22 by blade 80. Any peel adhering to drums 62 and 20 is removed by blades 82 and 84. Drums 20 and 62 are removably positioned by means and pneumatic cylinders 54, 56 and 74, 76, also see Fig. 2 (not shown). In an alternative form of apparatus, Fig. 5, the peeling step is carried out by placing cooked potato pieces on to movable perforated screen 210, and passed beneath rolls 214 and 216 so as to force the edible portions of the potato through the opening in the screen into auger trough 222. Doctor blades 226, 228 remove potato solids from the underside of the screen whilst other blades remove peel from the rolls and upper side of the screen.
