Title: Improvements in or relating to range finders
IPC: G01C3/10
Filed: 1946-05-28
Abstract: 617,916. Range-finders. ABBEY, A. (Arenco Aktiebolag). May 28, 1946, No. 16159. [Class 97 (i)] In a long home-base range-finder, the two sighting instruments are interconnected by a differential wheel gear, one wheel of which rotates in accordance with the variation of the angle alpha between the lines of sight from the instruments on to an object, rotation of this wheel causing electrical means to move a member for indicating the range from one sighting instrument tc the object, which member rotates a parallax angle member until the angle between this member and the path of movement of the range member equals x, whereupon the parallax angle member opens the circuit of the electrical means and thereby stops the movement of the range member. As shown, the telescopes 1, 2 pivot in the same horizontal plane and are each connected with a differential gear system 7-9, the telescope 1 being connected therewith through a self-synchronous electric transmission system 5, 6. The rotation of the spur-wheel 11, in which the wheel 9 is rotatably mounted, therefore corresponds to the variations in the angle alpha. Rotation of the wheel 11 causes rotation of an arm 14 to close one of two contacts 42 on a rotatable disc 15 and start up an electric motor 21 which drives a screwed arm 20.along which a nut 19 moves, this nut comprising the range member. Engaging the roller 18 which is rotatable on the nut 19, is a spring-urged arm 17 pivoted at 16 and connected through a gear system 39 with the contact disc 15; this arm is the parallax angle member. As the nut 19 moves along screw 20, the arm 17 rotates and imparts angular movement to the disc 15 until the electrical contact is interrupted. The angle which the arm 17 makes with the line joining the pivots 16 and 41 is then equal to alpha. An arrangement whereby the range from the telescope 1 to the target can be read directly from a scale may be used with the apparatus and comprises a slotted arm 22 pivoted at 44 on the nut 19 and through which projects a fixed stud 23. Slidable in said slot is a pin 24, which also engages slots 46, 25 in T-shaped carriages 28, 26 respectively, the slot 25 in carriage 26 also having a pin 31 on an arm 34 riding therein, the arm 34 being connected through bevel gearing with the telescope 2 so that it is maintained parallel therewith. The distance of the pin 31 from the pivot of the gear-wheel carrying the arm 34 may be adjusted to correspond with the length of the base line and with the arm 17 making the angle alpha with the line joining pivots 16, 41, the range indicated on the scale 29 which is engaged by the carriage 28 will give the distance from the telescope 1 to the target. Instead of the arm 17 engaging the roller 18, it may slidably or pivotally engage the rod 34 which may be rotatably journalled on the nut 19. In another embodiment, the arm 17 itself is journalled in the nut 19.

Title: Manufacture of boric acid
Inventor: BROWN MICHAEL PETER
IPC: C01B35/10
Filed: 1960-05-07
Abstract: Boric acid is made by treating an aqueous solution of an alkali metal borate with a cationexchange resin containing COOH groups. A Na borate, e.g. tetra borate decahydrate (borax), tetrahydrate (kermite), pentahydrate, or a polyborate may be treated at below 100 DEG  C., e.g. 80 DEG  C., with a cross-linked methacrylic acid resin, e.g. by passage through beads of resin in a column, and the boric acid may be crystallized from the solution by cooling.  Further borate may be added to the mother liquor which may then be treated with resin.  The resin may be regenerated by treatment with an aqueous solution, e.g. 20% of a strong acid, e.g. H2SO4, HCl or HNO3, in not greater than the theoretical amount for conversion to the H+ form.  The acid solution may contain the alkali metal-acid salt in such amount that the solution is not saturated at the resin treatment temperature, e.g. 70 - 90 DEG  C., but is saturated at a lower temperature, e.g. 20 DEG  C., and treatment of the resin with the acid solution is preceded by treatment with a neutral solution of the alkali metal salt, e.g. Na2SO4, which is crystallized by cooling (which may be preceded by evaporation) the effluent from the above acid solution.  Further acid may be added to a portion of the mother liquor which is then used to regenerate the resin.  The boric acid production and resin regeneration steps may be cyclic and the resin may be washed with water before each step.

Filed: 1962-04-30
Abstract: 969,272. Respiratory appliances. O. H. DRAGER, [trading as DRAGERWERK HEINR & BERNH. DRAGER]. April 30, 1962, No. 16521/62. Heading A5T. Breathing equipment for underwater use, incorporating a breathing bag and a carbon dioxide absorber, has means for supplying oxygen at a constant rate, irrespective of depth, and for supplying helium, or other inert gas, at a rate which increases with increase in depth. The breathing circuit comprises a mouth-piece connected through tubes 3, 5 to a breathing bag 1, within which is a carbondioxide absorber 2. The bag is supplied with oxygen from a container 6 through a pressure reducer 7 and constriction 8, the diaphragm of the pressure reducer being loaded solely by a spring. Helium, from a container 9, is however supplied through a pressure reducer 10 and constriction 10a, the former having two control diaphragms, one of which is responsive to water pressure while the other is responsive to the pressure in the bag 1. This is so adjusted that helium is supplied only at depths greater than 10 metres. A supplementary valve 11, connected to both supplies, controls the admission of both gases to the bag 1 and may be used for initially inflating the breathing bag. It is, however, dependent on the reducing valve 10 so that only oxygen can be supplied at depths down to 10 metres.

Title: Improvements relating to laundry folding machines
Inventor: ODD LESLIE FREDERICK
IPC: D06F89/00
Filed: 1952-07-02
Abstract: 754,109. Photo-electric control systems. BAKER PERKINS, Ltd. Sept. 25, 1953 [July 2, 1952], No. 16678/52. Class 40 (3). [Also in Group VIII] In a laundry folding machine of the type wherein articles are advanced by a conveyer to a folding station, the fold initiating means is displaceable by a reversible electric motor controlled by a thermionic valve circuit the circuits being actuated by means such as a photo-cell detecting the presence of the article to be folded. As shown, a sheet to be folded is carried by conveyer 2 between a light source 12 and photo-cell 11 and between a movable gripper 3 and fixed gripper 4. Interruption of the light beam to the photo-cell causes, after an appropriate delay to allow for spacing of the photo-cell and grippers, the lower gripper 3 to be rotated upwards driven by a motor 7 until the leading edge of the sheet is held. Motor 7 is then stalled. The conveyer then continues driving so as to form a bight in the article until the sheet has so far advanced as to restore the light beam when motor 7 is reversed allowing the leading edge of the sheet to fall on the trailing edge the motor again stalling. Circuit, Fig. 2. The motor M for adjusting the grippers is of the shunt wound D.C. type, its field being energized from an A.C. supply through a full-wave rectifier, and its armature MA being connected in series with thyratrons V1, V2 which are so arranged as to conduct in different directions. Thus according to which thyratron is fired the armature current consists of one set of half-cycles or the other of the A.C. supply. When the grippers are in the position shown in Fig. 1, cell P is illuminated causing VI to conduct so that motor MA is held stalled while tending to lower the gripper still further. The voltage drop across resistor R2 or in the anode circuit of V1 blocks V2. When cell P is covered V1 blocks, unblocking V2 which causes motor MA to reverse driving the gripper to its upper limit. To allow for the spacing of the photo-cell from the grippers, condenser C2 and resistor R3 delay the operation of valve V1 while resistor R4 and condenser C3 delay the operation of V2. The stalling current is limited by cathode resistors R8 and R7 the drop being impressed on the screen grid of V1 and grid of V2.
