Title: Periscope
IPC: G02B23/08
Filed: 1965-01-11
Abstract: 1,272,742. Periscope. ERNST LEITZ G.m.b.H. Jan. 11, 1965 [Feb. 15, 1964], No. 1260/65. Heading G2J. A periscope comprises a head 2 provided with a mirror 4 rotatable on a spindle 3 by a servomotor 5 and adapted to deflect light entering the head 2 through an aperture 1 down through a vertically mounted tube 7, the head 2 being rotatable in a bearing 6 at the top of the tube 7 by means of a motor 13. The motor 13, whose speed may be varied by a rheostat 13a and which may be switched to forward or reverse movement by a change-over switch 14, rotates the head 2 through a gear wheel 9 which meshes with internal teeth 8 on the head 2 and which is mounted on a shaft 10 driven through a clutch 12 and gears 11. The clutch 12 permits adjustment by means of a hand wheel 15 instead of by the motor drive. Mounted on the shaft 10 is a second gear wheel 16 which engages a gear wheel having internal teeth and carrying an image-erecting prism 17, the speed of rotation of which is in the ratio of 1:2 to the speed of rotation of the head 2. Thus, if the head 2 rotates 180 degrees, the prism 17 rotates 90 degrees. A zoom lens system 18 is provided between the prism 17 and the deflecting mirror 4 for producing a change in the scale of magnification. The light from the prism 17 is deflected by a prism 19 to a horizontal eye-piece 20. The periscope may be focused on a specific object by hunting (switching the motor over to forward and reverse) and switching off when the desired position is reached, or by manual adjustment after disengaging the clutch.

Title: Improvements in ornamental illuminating devices
IPC: F21S10/00
Filed: 1943-01-26
Abstract: 558,108. Ornamental lamps. OTIS, C. W. Jan. 26, 1943, No. 1304. [Class 75 (iv) ] An ornamental illuminating device shown in Fig. 3 suitable for Christmas tree decoration comprises a low wattage electric lamp bulb B mounted in a housing 16 supporting a pellucid tube 36 containing a volatile liquid such as wood alcohol, ether, or methylene chloride, means being provided at the bottom of the tube for preventing dissipation of the heat by circulation of the liquid and so promoting the formation of bubbles which rise to the top of the tube and are condensed in the partially evacuated space 52 above the liquid. In Fig. 3 these means consist of a tube 54 of glass, cellulose acetate or other pellucid material, closed at the top and having its open bottom resting on a seating 55 in the tube 36. The tube 54 is maintained in rapid vibration as bubbles of vapour formed below it escape and replenishing liquid flows beneath it. The tube 54 in urged downwardly by a spring or its own weight. In Fig. 4 the means consist of a solid glass cylinder 62 surrounded by a slightly larger open ended tube 68 which is of slightly smaller diameter than the tube 36. At starting the small body 66 of liquid below the cylinder 62 vaporizes and passes between the cylinder and tube 68. As larger amounts of vapour are generated the tube 68 is raised and vapour also passes between the tube 68 and the tube 36. The housing 16 may comprise upper and lower bells 24, 26 of tinted celluloid or formaldehyde condensate secured together by adhesive. Vents 44 are provided on both bells to allow a circulation of air through the housing.

Title: Improvements in or relating to impact wrenches
IPC: B25B23/145
Filed: 1963-01-11
Abstract: 965,516. Nut runners. FORGES ET ATELIERS DE MEUDON. Jan. 11, 1963 [April 27, 1962; Nov. 5, 1962], No. 1328/63. Heading B3N. A portable nut runner of the impact type comprises a tool holder having two opposite anvils, a carrier having a diametral passage, and an axial stub shaft rotatably driven from a motor, a pair of hammers radially slidable in the diametral passage, adapted simultaneously to strike the anvils, resilient means for urging the hammers inwardly to disengage them from the anvils, and a locking member rotatable with the tool holder and spring urged axially to lock the hammers in their retracted position, a flat face on the locking member being adapted to engage a circular cam face cut in the end of the carrier, to allow the locking member to lock the hammers, during slightly more than a half revolution of the carrier. The nut runner comprises a casing 30, Fig. 1, a reversible pneumatic motor controlled by a reversing knob 31, and an output knob 32, a splined motor shaft 34 engaging a splined bore in a hammer carrier 36, hammers 38, 39 in the carrier, a tool holder 51 having anvils 72 and a locking member 48. Hammers 38, 39, Figs. 1, 2, 3, are urged inwardly in a bore 65 in carrier 36 by a toroidal rubber ring 40 which engages grooves in pins 42, 43 carried by the carrier, and member 48 is rotatable with holder 51 through projections 54, 55 which also co-operate with a cam 66, 67 on the end of carrier 36 to move a face 64 on spring urged member 48 away from the hammers thus unclamping the latter. In operation member 48, Fig. 1, is moved axially by projection 55 and cam face 66, thus releasing the hammers, Fig. 3, which are moved outwardly by centrifugal force. Anvils 72 are held stationary by the nut to be tightened and as carrier 36 is rotated by the motor faces 73 on the hammers produce an impact on the anvils and therefore the nut to be tightened. The hammers are then moved inwardly by ring 40 and a disc 74, Fig. 7, which has cam faces 76 which engage pins 42, 43 and they are clamped by member 48 which has then moved axially. One blow is produced for each revolution of the motor. In a modification locking member 48 is replaced by two elements 48a, 48b, Fig. 24, which rotate relative to each other, but are relatively axially fixed, the hammers 38, 39 being locked by projections 82, 83, on member 48a, Figs. 41, 42, which engage elongated slots 88 in the hammers, and in this case the hammers are urged inwardly by ring 40 only.

IPC: B01D53/74
Filed: 1968-01-11
Abstract: 1,211,033. Removing SO 2  from waste gases. ONTARIO RESEARCH FOUNDATION. 10 Jan., 1969 [11 Jan., 1968], No. 1741/68. Heading C1A. Sulphur dioxide containing effluent gas is contacted with a reducing gas comprising H 2 S in the presence of a catalyst at a temperature of 50- 150‹ C. whereby the SO 2  is at least partially reduced to sulphur in accordance with the equation: and the sulphur is deposited on the catalyst, and removing the sulphur from the catalyst at least partially by reaction with carbon monoxide at a temperature of from 250-500‹ C. in order to provide regenerated, substantially sulphur free catalyst. The reaction with carbon monoxide preferably occurs at 300-450‹ C. The carbonyl sulphide produced may in turn be hydrolysed to CO 2  and H 2 S which is recycled, further H 2 S being produced if a mixture of CO and H 2  is used for removing the sulphur, steam (removing the necessity for subsequent hydrolysis) and an inert gas, such as N 2 , may also be present. Sufficient H 2 S is used in order to react with all the SO 2 , sufficient CO with or without H 2  is used to react with 2/3 of the sulphur produced, the rest being removed as sulphur vapour in the COS and subsequently removed; sufficient steam is used to hydrolyse all the COS produced. A continuous process for the removal of the catalyst from the sulphur depositing zone to the sulphur removing zone and: thereafter recycling the catalyst, is described. Catalysts disclosed for the sulphur producing stage are Pd, Pt, Rh, promoted iron oxide but preferably activated alumina or bauxite is used. This stage may be broken up into 2 parts: (a) reaction with H 2 S at 250-400‹ C. (b) completion of the reaction at 50-150‹ C. Some CS 2  may be produced especially if hydrocarbons are present in the CO or H 2 . This need not be hydrolysed since CS 2  will reduce SO 2  to S if recycled.

IPC: G05D23/24
Filed: 1955-01-20
Abstract: 791,882. Electric control and indicating systems. RHEOSTATIC CO., Ltd. Jan. 19, 1956 [Jan. 20, 1955], No. 1755/55. Class 40 (1). In a bridge circuit for indicating or controlling temperature three resistors C, D and R, Fig. 1, are mounted on a base at the part to be controlled and constitute two arms of the bridge. Resistor D is temperature-sensitive and resistors C and R are not. Resistors A and B constitute the other two arms of the bridge and an alternating supply is applied across points E, F. The output is taken from the junction of resistors A and B and the variable tap on resistor R, movement of which determines the temperature at which the bridge will balance. Figs. 4 and 5 show a construction in which resistor C is mounted on base plate 9. Resistor D comprising an open winding of fine wire is supported on pillars 10, 11 and resistor R is arcuate and is traversed by a wiper 7. Attached to wiper 7 is a pointer 15 which moves over a temperature scale and which may be decoupled from the wiper so as to be set against a calibrating temperature while the bridge is balanced. Since the resistance per unit length of this resistor may vary, the effective radius of different parts of the resistance from the wiper arm may be adjusted by means of screws 17, 18.

Abstract: 1,157,092. Automatic exchanges. ANSAFONE Ltd. 30 Sept., 1966 [14 Jan., 1966], No. 1832/66. Heading H1K. A telephone answering and recording device reverts to its standby condition in readiness for a fresh call in response to the brief cessation in line current or voltage at the breakdown of a connection. Fig. 5 shows a circuit D.C. coupled to the line for sensing an interruption in voltage. Relay RL is operated by a signal on lead 21 upon the device being put into its recording state in response to ringing current and is initially held by the voltage received by capacitor C11 as RL1 closes. Relay RLA operates after a delay to transfer the holding condition to capacitor C12 charged over contacts RLA1. At the end of a call the positive potential on wire L1 momentarily disappears allowing both capacitors C11 and C12 to discharge rapidly via the now-forward biased diode D11, so releasing relay RL which releases relay RLA and also switches the device to its standby condition. Relay RL does not immediately reoperate upon the return of line potential due to the slow recharge of capacitors C11 and C12. In another arrangement (Fig. 4, not shown), a relay D.C. coupled to the line releases upon the brief break in line current and applies a negative going pulse to a transistor to turn it on which in turn discharges a capacitor causing a second transistor to cease to conduct and so release a relay which switches the device to its standby condition.

Title: Process for the manufacture of purified germinal gland hormone preparations
Filed: 1937-01-22
Abstract: Germinal gland hormone preparations are purified by a process which comprises reacting preparations which contain the corpus luteum hormone together with inactive substances containing keto groups with chlorsulphonic acid, separating the salt forming from the non-salt forming portion, and isolating the corpus luteum hormone from the non-salt forming portion.  The salt forming portion is then saponified to isolate the inactive ketonic material.  The reaction of the chlorsulphonic acid yields sulphuric acid esters with the keto alcohols which form sparingly soluble sodium salts.  These are easily separated from the corpus luteum hormone fraction.  The process is also applicable to products which are obtained in the oxidation of pregnenolene.  In an example an ovarial extract is dissolved in a mixture of chloroform and pyridine and treated with chlorsulphonic acid.  The reaction mixture is heated on the water bath for half an hour and then treated with caustic soda and extracted with ether. The ethereal extract is washed with acid and water, the ether is removed and the progesterone crystallized from alcohol.  The sodium salt is saponified with 5N-sulphuric acid to give allo-pregnanolone. Specifications 450,325 and 451,939 are referred to.
