Title: Cardiographic apparatus with stylus control means
Inventor: WEINSTEIN BEREL
IPC: A61B7/04
Filed: 1971-04-14
Abstract: 1284513 Electro-medical apparatus BIO MEDICAL SCIENCES Inc 14 April 1971 9340/71 Heading G1N In a cardiographic device, electric signals representing heart action action are recorded by a stylus 80 on a web 54, Fig. 1, the stylus being moved in two opposite directions by a reversible motor 86 driving a screw 84 to which the stylus is attached, the motor 86 being driven in dependence upon the electrical signals from a heart action transducer 88 (electrodes or microphone). The motor control circuit 94, Fig. 3, includes a first switching device, consisting of transistors 96, 112, 114, 116 and a second switching device, consisting of transistors 118, 120, 122, 126, which switching devices cause current to be switched in opposite directions through the motor 86 in dependence upon the electrical signals. A pair of sources 140, 142 and a pair of potentiometers 138, 144 are provided to bias the stylus to a null position, the wiper 136 of potentiometer 138 being connected to the stylus 80.  In operation, the electrical signals are applied to the base of transistor 96 and the switching devices cause current to flow in one direction through the motor 86 to move the stylus 80. As the stylus moves across the web, the wiper 136 similarly moves to apply a potential opposite to that of the electrical signals applied by transducers 88. Movement of stylus 80 continues until these potentials are equal. The switching devices then cause current flow through the motor 86 in the opposite direction. The apparatus is stated to be portable, easily dismantled, and has its electrical components mounted on a printed circuit board.

Title: Preparation of printer's ink
IPC: C09D11/12
Filed: 1928-03-30
Abstract: 312,745. Maclaurin, R., and Maclaurin, I. M. March 30, 1928. Ink.-Low temperature or semi-low temperature tars are used as a basis for printing-ink. The tars used preferably contain only traces of naphthalene, a resinous or asphaltic product which is separated by the addition of petroleum or a paraffinoid oil, and a further resinous product which separates on the adddition of a 3 per cent solution of sulphuric acid or equivalent dilute acid. 'The' resinous products can be added to other portions of tar to render them suitable for use as ink. Other agents to retard drying, such as linseed oil, may be added. Tars containing 30-50 per cent resinous products are most suitable. Thinning-agents, such as turpentine, benzole, solvent naphtha, or tar from which the resinous products have been precipitated, can be used when necessary. The addition of ferrous hydrate tends to blacken the tar and renders the use of a smaller amount of pigment possible, In an example, a low temperature tar prepared from bituminous coals by a known process is heated with linseed oil and solid caustic soda, and carbon black or other black pigment added. According to the Provisional Specification, the distillates may be used as' thinning-agents, and ferrous sulphate may be added in place of ferrous hydrate.

Title: Apparatus for canning film magazines
IPC: G03B21/43
Filed: 1972-03-02
Abstract: 1372746 Canning film magazines EASTMAN KODAK CO 2 March 1972 [5 March 1971] 9713/72 Heading G2X A film magazine is loaded into a protective can by inserting it into a housing, aligning the housing with the can, and then urging the magazine from the housing into the can. As shown, the magazine 12 containing the roll of film, from which the leader end (19), Fig.6 (not shown) is left extending, is moved by a transfer arm 14 from the spooling station to the insertion station 17. Here it is pushed by a pusher 20 on the end of a sliding rod 24 into a cylindrical open-ended housing 26, the housing having an elongated slot (30) in its wall to accommodate the leader. The end of housing 26 opposite to pusher 20 is closed by a rotatable piston 32 having a finger 36 extending therefrom (seen more clearly in Fig.3 (not shown)). When magazine 12 is pushed into the housing, piston 32 is pushed back against a spring 53, finger 36 lying between the magazine and the wall of the housing. Spring 53 surrounds the rod 40 of piston 32, the rod ending in a knob 52. Housing 26 is mounted on a support 49 which carries a pinion 43. The pinion engages with a toothed gear sector 64 which is fixed to a plate 66. A rod 61 is connected by a link 58 to a member 55 to which support 49 is fixed. Thus as rod 61 moves to the right, member 55 is rotated anti-clockwise, carrying housing 26 with it through a 90 degrees rotation into the can loading position shown in dotted line in Fig.1. Pinion 43 rolls along toothed sector 64, causing rotation of rod 40, piston 32 and hence finger 36. This engages the film magazine and rotates it to wind the film leader round it Fig.6 (not shown). At the cam loading station 48 rod 40 is now in alignment with a pusher 74 fixed to an actuator plate 77. When this is actuated downwards, the pusher 74 engages against knob 52 and pushes magazine 12 out of housing 26 and into the can 100. The cans are supplied from an endless conveyor 102 (Fig.4) to an indexing mechanism 101 which comprises a circular support plate 104 and a pair of star wheels 106 which have pockets 105 into which the cans fit. As the can reaches the loading station 48 it is held by vacuum suction and the magazine pushed into it. The loaded cans are now removed along a conveyor 131. The sequence of operations is controlled automatically by electrical and/or pneumatic means.

Title: Improvements in electromagnetic relays
IPC: H01H51/32
Filed: 1937-04-06
Abstract: 491,980. Electromagnetic relays. GENERAL ELECTRIC CO., Ltd., and COLLYER, J. E. April 6, 1937, No. 9818. [Class 38 (v)] A relay operated on " and " off " by signals of two corresponding frequencies comprises two tuned reeds 9, 10 vibrating at the two frequencies to operate respectively two levers 14, 15 carrying springs 16, 17 which drive two ratchet wheels 21, 20, geared to the two side wheels 25, 24, of a differential gear. The vibration of the reeds is caused by current of the appropriate frequency in two coils 1, the polepieces of which embrace the ends of the reeds and are polarized by a magnet 2. Supposing the reed 10 vibrates, the ratchet wheel 20 is driven and in turn drives the wheel 24 so causing the centre wheel of the differential to rotate on its axis 29 and drive a wheel 30. A pin 40 on the wheel 30 then after about 120‹ lost motion engages a cam 31 situated between the forks 33 of the carrier of a mercury switch 7. The switch 7 is thus tilted " off and the cam 31 can turn no more. Should the signal continue, the rotation of the wheels 20, 24 now causes a backward idle movement of the side wheel 25 of the differential since the centre wheel is locked. Subsequent reception of a signal of the other frequency causes the reed 9 to vibrate and side wheel 25 'to rotate forwardly driving the centre wheel so that the pin 40, after lost motion, moves the mercury switch 7 back again.

Title: Improvements in or relating to nuclear reactors
Inventor: DIAMOND JACK
IPC: G21C1/00
Filed: 1953-04-11
Abstract: 796,991. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. July 12, 1954 [April 11, 1953], No. 9898/53. Class 39(4). In a nuclear reactor comprising a liquid moderator and fuel element channels in the moderator through which channels a coolant fluid is arranged to flow, heat insulating means is provided between the coolant fluid and the moderator. Referring to Fig. 3a the fuel elements 21 are arranged in coolant channels 20 which are connected together in pairs to an inlet header 23 and an outlet header 24 for the liquid metal coolant; connecting pipes 25 couple the cooling channels together so that the coolant passes twice through the reactor core in every cycle of circulation. The coolant channels are surrounded by tubes 28 which connect the two header tanks 26, 27 containing heat insulating gas. The tubes 28 are surrounded by water which acts as a moderator. The heat insulation provided by the gas in tubes 28 prevents excess heat passing from the coolant to the moderator, but some heat must inevitably flow so it is arranged that the moderator is circulated and cooled. The fuel may be of enriched uranium, and the moderator may be water, heavy water, or a liquid hydrocarbon ; the coolant may be sodium. The heat insulation may be provided by a vacuum space instead of a gas-filled space. As shown in Fig. 1, a plurality of reactor units 2 may be arranged in a stainless steel tank lining a cavity in a concrete shield 3. Each reactor vessel 5 is arranged between two gas headers 4, 6 the upper of which is surmounted by a neutron shield 7, expansion pieces 8, a heat exchanger 9, a pump 10 and motor 11 for the primary coolant, and a gamma ray absorbing shield 12. The reactors may be controlled by rods 45.

IPC: B66C1/42
Filed: 1962-03-15
Abstract: 962,487. Furnace - charging machines. ROBEY & CO. Ltd., and C. MEADOWS & CO. Ltd. March 14, 1963 [March 18, 1962], No. 9938/62. Heading F4B. [Also in Division B8] A pivotally suspended horizontal beam 1 has power-operated load holding means such as grippers 6 at one end, its pivotal support 3 between its ends, a counterweight 34 movable along the beam and a control unit 24 at the other end. The beam is particularly for handling loads within a limited headroom, e.g. for removing billets from a furnace. The control unit 24 consists of valves operable either manually from the beam itself or by remote control, e.g. an associated crane or overhead trolley from which the apparatus is suspended. These valves control the flow of pressure fluid from a pump-and-motor unit 21, 22, which may constitute, wholly or in part, the counterweight 34. The latter is movable along the beam by an hydraulic ram 23, Fig. 3 (not shown), and the whole beam may be raised and lowered by a like ram 5 from which it is suspended. A third ram 16 controls the grippers 6 and the arrangement is such that the grippers are openable only with the counterweight in the position (Fig. 1) in which it balances the unloaded beam, this being ensured, e.g. by a mechanical device operable on movement of the counterweight out of this position to actuate the valve controlling the ram 16. Operation of grippers.-The ram 16 carries a cross-head 15 on which a pair of rollers 13 are mounted to engage external cam surfaces 11 on the gripper arms and so open the gripper arms, which are pivoted together at 8, whenever the ram is retracted. A roller 14 on the cross-head likewise engages internal cam surfaces 12 on the gripper arms to open them when the ram is extended. In the extended position, the roller 14 tends to wedge between the arms so that the grippers only reclose on positive retraction of the ram.
