Title: Improvements in printing telegraph apparatus
IPC: H04L17/02
Filed: 1957-09-16
Abstract: 834,080. Type-printing telegraphy. HANDLEY, J. Sept. 12, 1958 [Sept. 16, 1957J, No. 29016/57. Class 40 (3). Telegraph transmitter apparatus comprises a plurality of combination members which can be selectively positioned according to a character code combination either under control of a key of a keyboard through a first set of interponents or according to a combination read from a perforated tape, through a second set of interponents and means are provided to sense the positions of the combination members to transmit a signal combination corresponding to the said positions. The operation of a key lever allows spring-biased code bars to move selectively to rock associated interference members 32, Fig. 1, so that their upper ends 32', when rotated to the left, can obstruct associated combination members 9 biased downwardly by springs 10. At the commencement of a revolution of a cam-shaft 11 released by the action of a key lever, a cam lowers a restoring bail 12 so that the bars 9 which are not obstructed by the rocked ends 32<1> of the members 32 can move downwardly and subsequently a cam moves a locking bail 15 to the position shown in Fig. 1 in which it locks the members 9 in their adjusted positions. Sensing levers 17 released for activation sequentially by cams 18 on the shaft 11 rock a transmitting bail 19 if their downwardly extending arms 17<1> are not obstructed by the upper portions of the associated combination members 9. For transmission from a perforated tape the cam-shaft 11 is rotated continuously and a bail 8 engaging T-shaped plate members 31 moves to the left five interference members 6 individually connected to rotatable bell-cranks 5 each carrying a block 47, Fig. 5, with a pin 4 for sensing a hole position in the tape. If a pin 4 detects a hole, the associated bell-crank 5 is rotated to allow the associated interference member 6 to move forward to the position in which it prevents the downward movement of the corresponding combination member 9. After the settings of the members 9 have been locked by the bail 15, the bail 8 restores the members 6 to the left, and a cam on the shaft 11 operates lever members to step the next row of holes in the tape to the sensing position. The mechanism for transmission from the tape is disabled by rotating a shaft carrying a rocker which obstructs the movement of the lever carrying the tape-feed pawl, and through two co-operating gear-wheels rotates a shaft 49 carrying a locking pawl 29 which in its operated position engages lower portions of the T-shaped plates 31 to hold the interference members 6 in their left-hand positions out of engaging relation with the members 9. The code bars operated by the key levers are restored and the signals transmitted in known manner.

Abstract: 857,246. Railway vehicle sanding apparatus. GRESHAM & CRAVEN Ltd. Dec. 23 1958 [Sept. 23, 1957], No. 29829/57. Class 103(3). Apparatus for applying an abrasive paste on to the tyre 1, Fig. 1, of a railway vehicle wheel to improve its adhesion on the rail 3, comprises a container 5 for the paste mounted on the vehicle frame 4 and supplied with air or steam under pressure through a pipe 9; a nozzle 14 connected to the container 5 through a flexible hose 13 and a pipe 10; and a bracket 17 carrying the nozzle and pivoted to the vehicle frame at 15, the bracket also being connected to a piston operating in a cylinder 21, through a lever 18 pivoted at 19 to a rod 20 connected to the piston. The piston when inoperative is under the urge of a spring to cause the nozzle to pivot away from the wheel. When pressure is applied to the container 5 it is at the same time applied to the cylinder 21 to cause the piston to move the nozzle into the fuel line position, whereby paste is delivered on to the tyre to be carried to the rail. The paste is contained in a cardboard cylinder of which the ends are removed so that it can be inserted into the container 5 and rest on flanges 8 therein. When the pressure is cut-off the paste ceases to flow but if a less viscous material is to be used then a valve as shown in Fig. 2, is employed to cutoff the flow. The valve 33 is normally urged by a spring 34 to close a port 35 to the pipe 10. The valve is connected by a rod 32 to a piston 30 engaging a flange 37 at the bottom of a cylinder 38 also connected to the air or steam supply by a pipe 39. Clearly when pressure is applied to the container and cylinder the valve 33 is opened and the material is also forced under pressure from the container 5 through ports 40.

Abstract: 364,667. Holding appliances for animals. MACLEOD, J. T., 88, Cadogan Street, and THOMSON, J., 13, Kerona Avenue, Scotstoun, both in Glasgow. Oct. 6, 1930, No. 29804. [Class 81 (ii).] Relates to stunning or slaughtering pens for animals, of the kind in which the floor is adapted to tilt laterally about either side and is connected to the side walls, which latter slide upwards, when the floor tilts, to provide an aperture through which the carcass is discharged. According to the invention, the floor A of the pen is of steel chequered plating and is supported by shafts B the ends of which operate in slots G in bearing plates H. The shafts pass through boxes C secured to the lower side of the floor and are pressed outwards by springs D. Either one of the shafts may be actuated to tilt the floor by an associated lever I which is keyed to a horizontal shaft K, the latter being journalled in a bracket L which is secured to a vertical channel member M. The lever actuates a spring-controlled connecting-rod P the lower end of which contacts with one arm T of a pivoted lever. Another arm W of this lever is connected to a striking block Y a finger Y<1> of which is adapted, upon the operation of the lever I, to press the shaft B inwards against the action of the springs D. This inward movement brings the ends of the shaft adjacent the substantially vertical part of the slot G and the floor tilts under the weight of the animal. The floor is connected by wire cords p to the verticallyslidable side walls of the pen, the lower parts of which are hinged to swing outwards, the cords passing over pulleys attached to top longitudinal channels of the pen. The main vertical members of the pen consists of inner and outer steel channels and are braced by longitudinal and lateral plates and channel members.

Title: Improvements relating to electronic circuits and networks of use in flame monitoring apparatus
Inventor: INNES DAVID CHARLES KENNETH GO
IPC: F23N5/08
Filed: 1963-07-29
Abstract: 1,101,181. Flame monitoring circuits. BABCOCK & WILCOX Ltd. July 29, 1964 [July 29, 1963], No. 30041/63. Heading G1A. [Also in Division F4] The invention relates to a flame monitoring circuit of the type in which flame flicker is detected by measuring the ratio of A. C. to D. C. signals produced by a photo-conductive cell. The disproportionate decrease in the A. C. signal at low light levels due to increased cell inertia is compensated by connecting the cell 41, Fig. 2, in series with a silicon or gold bonded germanium diode 44 whose A. C. resistance increases as the D.C. therethrough decreases. The parameters of the cell, diode and resistor 43 may be chosen so that the A. C. voltage applied to transistor 54 is proportional to the variations in flame intensity. The ratio of this compensated A. C. signal to the D.C. cell current is measured by means, including diode 47, as claimed in Specification 1,101,182. A signal is taken at 69 to indicate the D. C. current of the cell with enhanced sensitivity owing to the increased D. C. resistance of diode 44 at low currents. This signal indicates the cleanliness of the sight glasses associated with the cell.

Title: Leakage warning device for pneumatic tyre
IPC: B60C23/04
Filed: 1975-07-17
Abstract: 1466551 Tyre deflation warning device CHIANG SHUI SU 17 July 1975 30132/75 Heading B7C A tyre deflation warning device comprises a cylinder body 1 adapted to be fitted to the inflation valve stem of a tyre, a resiliently biased piston 2 movable to open a valve to allow passage of air from the tyre cavity into an inflatable and rupturable rubber sack 8 only when the air pressure in the tyre drops to below a predetermined value, and means for preventing the escape of air after the sack has ruptured, the rupturing providing an audible warning. In a preferred device the piston acts directly on the pin 101 of the tyre inflation valve. When the tyre air pressure drops to below the predetermined value the piston is moved to abut seat 11 and the inflation valve is opened. Air escapes into the sack which subsequently bursts, and the sudden increase in air flow forces ball 5 into sealing engagement with aperture 631 to prevent further air flow. In a modified form, the tyre inflation valve is held open by a projection 151 and the spring biased piston and tyre air pressure act directly on a valve member 16.
Patent GB-365046-A (GB)
Title: Improvements in and apparatus for the working up of substances containing asphalt, such as tars, petroleum, destructive hydrogenation products of coals and the like by separation of asphalt therefrom
IPC: C10G21/00
Filed: 1930-10-08
Abstract: <PICT:0365046/III/1> In a continuous process for separating asphalt and dust from liquid or fusible carbonaceous materials such as tar, petroleum, or cracked or destructive hydrogenation products of these, by treatment with a precipitation agent, the asphalt is separated in two or more stages.  Suitable precipitation agents are liquid aliphatic hydrocarbons, e.g. benzine, petroleum, gas oil, or cracked or hydrogenated products thereof, or alcohols, acids, ketones or esters.  When it is not desired to recover the precipitating agent from the asphalt, molten paraffin wax may be used.  Producer or brown coal tar C is fed through a pipe B, shown in the Figure, into a vessel A where it is mixed at 200 DEG  C. with kerosene admitted through a pipe C.  The resulting mixture of tar and precipitated asphalt passes through a drum filter D, and the separated asphalt is treated in a spiral E with superheated steam admitted through ports F, whereby kerosene is distilled off and condensed in the worm G. The oil filtrate from the drum D is treated in a second vessel J under stronger precipitating conditions to separate the remaining asphalt by (1) further addition of kerosene admitted through a valve H, (2) decreasing the temperature first to 150 DEG  C. and then to 100 or 50 DEG  C., (3) prolonging the time of treatment, or by a combination of these. The liquid asphalt passes through a valve K to a still N, and the asphalt-free oil passes through a pipe L to a still M, the resulting kerosene vapours being condensed in a worm Z. In a modification, the filter drum D is replaced by a spiral press which kneads together the asphalt separated in the mixing vessel, the pressed asphalt being then treated with steam, and the residual oil passing to the second precipitation vessel.  The asphalt-free oil may be used as a lubricant.

Title: Improvements in thermally operable electric switch devices
Inventor: BATTLE DEREK JOSEPH
IPC: H01H37/66
Filed: 1962-08-07
Abstract: 990,563. Thermal switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. June 21, 1963 [Aug. 7, 1962], No. 30204/62. Heading H2B. In a room thermostat, a thermally responsive bimetallic spiral 24 is separated from contacts 12, 21 and 13, 22 and other parts of the switch which may carry current, by a partition 33. The switch base 1 has four terminals 5, 6, 7 and 8, line terminal 5 being connected through a conducting strip 16, spring 19 and armature 20 to contacts 21, 22. The fixed contacts 12, 13 are connected through conducting bars 10, 11 to terminals 6 and 7. As the room temperature increases, the spiral 24 expands and the free end engages and moves a heat insulating member 23 which opens contacts 12, 21 and closes contacts 13, 22. The contacts 12, 21 may be included in a circuit with a heater. A magnet 24 cooperates with the armature 20 to provide snapaction for the contacts. A pointer, Fig. 3 (not shown), connected to the centre of the spiral 24 and viewed through a window in the casing, adjusts the spiral and thus the setting temperature of the thermostat. Contacts 12 and 13 may also be adjustable. An accelerating heater resistor 31, connected between terminals 6 and 8, is located in a niche 32 which concentrates heat on the spiral. Stops may be provided to limit the movement of the pointer and thus select day and night temperatures for the thermostat.
