Abstract: 1,160,445. Measuring and sorting bottles. HERMANN HEYE. Aug.23, 1966 [Aug.25, 1965], No.37846/66. Heading G1M. In apparatus for sorting bottles, the bottles 1 are fed on a conveyer to a testing station where they are each clamped between support rollers 22 and piston 31. The arrival of a bottle is detected by means such as a photo-cell 45 which triggers an electronic circuit to provide timing signals to (i) operate the clamp, and (ii) move a sensing element 40 into the neck of the bottle. If the diameter is non-standard an electronic signal is provided which operates an ejector piston 27 Fig. 2 to remove the bottle. The sensing element 40 has a varying diameter to vary the distance it falls into the bottle, and the positioning of projection 41 on element 40 with respect to photo-cell 42, provides the sensing signal.

Abstract: 1362071 Catalytic reactions BADISCHE ANILIN- & SODA-FABRIK AG 13 Aug 1971 [14 Aug 1970] 38030/71 Heading B1F [Also in Division C2] In a process for carrying out an exothermic reaction between a gas and a liquid in the presence of a catalytic fixed bed with improved space-time yields and improved removal of heat, the gas and liquid are passed concurrently downwardly through a reactor containing the fixed bed, and downwardly through the fixed bed in the form of transition flow referred to below by passing the gas and liquid concurrently downwardly through the fixed bed so as to cause a pressure difference #p to be set up between the upper and lower ends of the bed, and controlling the rate of the reaction so as to maintain the ratio of the rate by volume of gas fed to the bed to the rate by volume of off gas produced from the reaction after correcting to N.T.P., at from 4:1 to 100:1, the gas fed to the bed being at least partly consumed during the reaction and the rate of flow, F, of the liquid through the bed being at such a value t that, at a constant rate of feeding the gas to the bed, the change of pressure difference #p with respect to changes in liquid flow rate i.e. d(#P)/dF, is at least twice as great when F equals t as when F equals l, being a liquid flow rate which causes at least predominantly laminar flow of the liquid through the bed, and the value t not being great enough to cause pulsing of pressure differences #p. The transition flow is as defined in A.I. Ch. E. Journal, Vol. 10 (1964) pp 952-953. In Example 1, in which butynediol is formed from formaldehyde and acetylene, column 1, Fig. 2, is packed with pelleted supported catalyst comprising 85% by weight of silica gel, 12% by weight of CuO and 3% by weight of Bi, 37% aqueous formaldehyde is introduced at 11a, at 1 litre/hr, acetylene at 5 atm guage is fed through 9a at 120 litres/hr (S.T.P.) so that the pressure differential between gas feed to the column and the off gas is 0.3 atm. gauge. Product is withdrawn at 15. In Ex. 2, 2-ethyhexanol-1 is prepared by hydrogenation of 2-ethylhexen-2-al-1, and in Ex. 3 trimethylhydroquinone is prepared by the hydrogenation of trimethyl-p-benzoquinone in isobutanol.

Title: Servo shoe brakes
IPC: F16D51/50
Filed: 1928-12-24
Abstract: 325,059. Riley (Coventry), Ltd., and Riley, S. Dec. 24, 1928. Blocks and shoes acting on drums.- In a servo-brake, two actuating cams 10, 11 rotatable about fixed axes engage the opposite ends of brake shoes 2, 3 and are interconnected by loadbalancing mechanism 17 such that servoaction can be obtained in either direction of rotation. The cams 10, 11 are connected by their arms 13, 14 and links 16 with the ends of a balance beam 17 connected with the brake rigging 18. The opposite ends of the shoes 2, 3 may be connected by links 19 with a floating radius arm 7 so that as the shoes are applied there is an outward thrust on their ends 4, 5. On application of the brakes, with the drum 9 rotating in the direction of the arrow, the cams 10, 11 turn and force the shoes into contact with the drum, and the shoe 2 leaves the cam 10 when a rotational effect is imparted to it by the drum. The frictional drag on the shoe 2 is imparted through the links 19 to the shoe 3 which abuts the cam 11 and turns this cam back into its original position. Further movement of the brake rigging turns the cam 10 to follow up the movement of the end of the shoe 2 and applies additional brake pressure. The abutting faces of the cams 10, 11 with the ends of their respective shoes may be parallel so that there would be an outward component of pressure from the cams against the adjacent ends of the shoes. The Provisional Specification states that the ends 4, 5 may engage guides so that as they move from their " off " position they move outwards slightly.

Title: Refrigerating apparatus
IPC: F25B13/00
Filed: 1974-09-03
Abstract: 1464453 Refrigerating DAIKIN KOGYO CO Ltd 3 Sept 1974 [21 Sept 1973 (2)1 38462/74 Heading F4H A refrigeration system comprises in series a compressor 1, a four-way valve 2, an outdoor heat exchanger 5, a receiver 6c, an expansion valve 4, a room heat exchanger 3 and an accumulator 6. The accumulator and the receiver are in indirect heat exchange contact with one another. Also incorporated in the circuit is an auxiliary heat exchanger 7 and a four-way changeover device 9. In operation of the refrigeration system, either in a heating or cooling mode, the flow through the expansion valve 4, the auxiliary heat exchanger 7 and the accumulator 6 is always the same. The accumulator 6 includes a low pressure inlet duct 13, a main body portion 6a, an outlet duct 14 and an oil return pipe 6e. A heat exchange coil 6b connects the receiver 6c to the expansion valve 4. The auxiliary heat exchanger 7 is disposed in parallel with the accumulator 6 and comprises a main body 7a connected to the inlet pipe 13 and the outlet pipe 14. A finned tube 7b passes through the main body 7a connecting the device 9 to the receiver, so that heat exchange can take place between the refrigerant under lower pressure passing through the main body 7a and the refrigerant under higher pressure passing through the finned tube 7b. A control temperature sensing element 4a for the expansion valve 4 is mounted on the outlet pipe 12 of the auxiliary heat exchanger 7. In another embodiment (Fig. 4, not shown), an electric heater is hermetically inserted in the auxiliary heat exchanger 7 to serve as a heat source instead of utilizing the high pressure side of the refrigeration system. In a further embodiment, Fig. 6, the four-way changeover means 9, the auxiliary heat exchanger 7, the receiver 6c and the accumulator 6 differ in construction from that shown in Fig. 1. In operation, irrespective of the mode of operation, refrigerant flows in a constant direction through the auxiliary heat exchanger 7, the receiver 6, the expansion valve 4 and the accumulator 6. Pipes 11, 12 of lesser diameter than the pipes 13, 14 connect the auxiliary heat exchanger 7 is parallel with the accumulator 6. The openings into and out of the pipes 11, 12 are as shown in Figs. 7, 8. Heat exchange can therefore take place in the heat exchanger 7 between all the refrigerant under higher pressure which passes through the outer tube 7a and a portion of the refrigerant under lower pressure which passes through the inner tube 7e. A temperature sensing element 4a for controlling the expansion valve 4 is mounted in the pipe 12 to detect the degree of superheating of the refrigerant and to adjust the opening of the expansion valve accordingly.

Title: Improvements in or relating to electric motor control arrangements for use in the transportation of web
Inventor: CHALMERS DAVID ARTHUR
IPC: H02P5/50

Abstract: 933,862. Control of several A.C. motors. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 30, 1959 [Nov. 28, 1958], No. 38498/58. Class 38 (3). When a switch SWA is closed, full power is applied to a take-up motor 10 for reeling magnetic tape, reduced power being supplied to the running winding 13 of capstan motor 12 through resistors R1, R2, in parallel. Full mains power is also applied to starting winding 14, the motor 11 coupled to the supply spool being de-energized. At a predetermined speed of the capstan roller, centrifugal switch 15 opens so that full power is now applied to the running winding 13 and the starting winding is disconnected. The take-up motor 10 receives reduced power through resistor R1, whilst the motor 11 is excited with D.C. braking current through resistor R3 to provide a back-tension. The tape thus reaches full speed and continues so to travel until the end of the tape is approached, whereupon a signal from photo-sensitive device P1 or P2 causes the starting winding 14 to receive full power in the reverse direction, the running winding 13 receiving reduced power. The capstan motor slows down, and simultaneously the motor driving the new take-up spool receives full power. The tape is accelerated until the centrifugal switch 15 opens whereupon the power supplies are changed to bring the tape to full speed. During the change-over it is necessary for relay RLF4 to be energized even though the centrifugal switch 15 is open and this is achieved by means of mercury switch 16 responsive to the direction of rotation of the capstan motor. Movement of the tape is stopped by opening switch SWA to de-energize the capstan motor, apply a small alternating-current to the take-up motor, and a direct braking current to the supply motor. After a predetermined period, both motors are de-energized. In the system described the tape is brought to rest due to the provision of transparent portions at the ends thereof, a switch SWB being operated when a spool is half full. With such an arrangement the length of transparent portions of the tape may be reduced. The photo-sensitive devices may be replaced by recorded signals at the ends of the tape. A switch 23 is coupled to switch 16 to ensure response to the signal from the photo-cell which occurs nearest to the end of the tape which is being approached and not to a signal which is received during acceleration of the tape. If the tape stops in the middle of its length due to power failure, the switch SWB ensures that, upon re-starting, the take-up spool is the one with the least amount of tape.

Abstract: 1276773 Seaming non-metallic sheet material KOEHRING CO 13 Aug 1970 [13 Aug 1969] 39065/70 Heading B5K In a method of friction welding two thermoplastic parts 12, 14 together by relatively rotating the parts 12, 14, the relative rotation is stopped to locate the parts in a particular position of relative angular orientation. The part 12, Fig. 2, having sockets 13 into which nozzle fittings 14 are to be friction welded in a particular angular position, is located on a non-rotatable plate 10, see also Fig. 3, with metal pins 11 extending through the sockets 13 and the particular socket into which a part 14 is to be welded being concentrically disposed relative to a support plate 10a. The part 14 is loaded into a socket in a tool 19 and is a friction fit therein. An air cylinder 41 is energized to move a pulley 36 outwardly and swing an endless belt 37, driven by a power transmission unit 31 coupled to a motor M, into engagement with a spindle 21 secured to the tool 19 to bring the spindle 21 up to the desired speed, e.g. 5000 revolutions per minute. The cylinder 41 is then de-energized and the belt 37 disengaged from the spindle 21. Cylinders 18 move the plates 10, 10a upwardly and cylinders 27 move the tool 19 downwardly to seat the part 14 within the socket 13. Fingers 44, 45, Fig. 6, pivotally mounted by pins 46, 47 on a flange 21a of the spindle 21 and connected by springs 50, 51 to posts 52, 53 fixed to the flange 21a, are in the solid line position of Fig. 6 under the influence of centrifugal force, the portions of the fingers 44, 45 rearwardly of the pins 46, 47 being heavier than the forward portions. The springs 50, 51 are so chosen that, at about the time the part 14 has one more revolution prior to a weld being completed, they overcome the centrifugal forces exerted at this lower speed and cause the fingers 44, 45 to move to positions 44<SP>1</SP>, 45<SP>1</SP>. As rotation in the last revolution occurs, the finger 44 slips past a fixed stop pin 43 whilst the finger 45, upon engaging the pin 43, halts the rotation of the spindle 21. The finger 44 prevents the spindle 21 from rebounding in the reverse direction. A polyurethane cushion 43a may be provided on the pin 43. The cylinders 18, 27 are de-energized to withdraw the plate 10 and the tool 19. The part 12 is withdrawn from the plate 10 and located thereon in another position to weld another part 14 into another socket 13.

Abstract: 842,190. Boring earth &c. IMPERIAL CHEMICAL INDUSTRIES Ltd. Dec. 15, 1958 [Dec. 18, 1937], No. 39309/57. Class 85. Deviations of a cutting head in a borehole are detected and corrected by means within the head operable from ground level. In Fig. 1, the cutting head 3 is connected to the drill pipe string 1 by a member 2 having some flexibility, and a sensing-means 8 rotatable in a ball and needle roller bearing 15, 7 is projectable, into a frusto-conical cavity 12 of the head, by an axially movable string 5. Passages 4 in the bearing 9 admit drilling fluid to passages 60 and 61. If the'cutting head deviates radially to the bore axis, the direction and extent of the deviation may be detected by stopping the drill and probing the cavity with the sensing device 8 which is moved around as well as vertically, in the cavity, the results being shown by indicators 10, 11. The deviation is corrected by applying resilient, e.g., spring or pneumatic pressure, by means of the sensing means 8, to the appropriate side of the cavity. The cutting head is then rotated without downward pressure, the means 8, 5 remaining static until the deviation is eliminated, when the drilling again proceeds with the means 8, 5 rotating with the drilling assembly. In a modification, the cutting head is driven by a dog-clutch connection with the end of the drill string which, with a ball-andsocket mounting on the string, permits slight radial deviations of the head. Such a deviation is detected by a roller-ended sensing device on the cutting head ball-andsocket mounting which projects upwardly into a canted cylindrical recess in a plunger-like end of the axially movable string 5. The nature of deviation is detected by probing the canted recess with the roller-ended sensing device which latter is positioned to bring the head back into alignment. In a further modification, the deviation is detected hydraulically, the drilling fluid, issuing into the cavity 59 from a nozzle 58, remaining at constant pressure as long as the cutting head is concentric with the nozzle tube 53. The nozzle is rotated at a speed different from that of the cutter 3 and eccentricity is detected by variations in hydraulic pressure. The pressure builds up at the side which needs internal pressure from the nozzle to correct the alignment. In a modification of the hydraulic embodiment, the nozzle 58 is used only as a sensing device and is vertically movable by a string corresponding with 5 of Fig. 1. The cutter 3 is driven by a dog-clutch arrangement from the bottom of the drill pipe. When the string 5 is raised, steep pitched helical grooves in the bottom of the string engage pins projecting inwardly from thrust collar bearing members which turn in opposite directions when the string 5 is moved axially. The bearing members have sloping end faces which act cam-wise to cant the cutter 3 in the required direction.
