Title: Improvements in machines for pressing soap cakes
IPC: C11D13/16
Filed: 1950-11-24
Abstract: 697,741. Pressing soap cakes. S.A.F.F.A. SOC. ANON. FABBRICHE FIAMMIFERI ED AFFINI. Nov. 24, 1950 [Nov. 25, 1949]. No. 28833/50. Class 87 (ii). [Also in Group XXX]. Unpressed cakes of soap are transferred from a conveyer to a pressing table by means of a plunger which is released by the movement of the oncoming soap cake and is timed to operate in conjunction with the press mechanism. A piece of soap A on the feeding belt 1 abuts the blade 2 and short-circuits contacts 7. 8, in the circuit of an electro-magnetically controlled stop 10. The stop withdraws to release the cam-controlled lever 11 of pusher 12 which thereupon pushes the piece A onto the work-table between the oscillating checks 16, 16<SP>1</SP>. In order that the transfer movement may only take place at a given time during the workcycle of the machine, the circuit of the electromagnetic stop 10 is also controlled by a brush 14 which revolves on the machine shaft and closes the circuit once per revolution. The soap piece is gripped between the cheek 16<SP>1</SP> and spring- cushioned, embossed plates 17 mounted on the opposite cheek 16. The cheeks 16, 16<SP>1</SP> advance the soap piece in steps through positions B, C, D, etc. They perform three movements viz., (a) a horizontal, transverse gripping and releasing move-. ment controlled by the cams 19, 19<SP>1</SP>, Fig. 3; (b) a vertical lifting and depositing movement controlled by cams 21, 21<SP>1</SP>; (c) a longitudinal feed and return movement controlled by cams 51 and levers 22. During the return movement of the cheeks 16, 16<SP>1</SP> a pressure lever 26 descends and holds the soap cake firmly on the table. In the position E the soap cake is gripped and guided into the mould 23' by two arms 41, 41<SP>1</SP> pivoted at 43, 43' which perform (a) a horizontal gripping and release movement controlled by racks 44, 44', pinion 45 and cam 47; (b) a vertical reciprocatory movement controlled by levers 48, 48' and cam 49. When the cake is in position, an upper die 24 pushes it into the mould. Simultaneously a lower die 23 rises slightly and the soap is compressed and printed on its upper and lower surfaces. The die 23 then ejects the cake and it travels through position F to take-off conveyers 5, 6. The stop push-button 27 of the machine is arranged in parallel with a cam-controlled switch Fig. 6 (not shown) which is opened once during every working cycle of the machine when the top and bottom dies 23, 24 are at the top dead centre and the plunger 12 is locked in the position of rest. This ensures that the machine will always stop with the dies &c. in these positions. An automaticallyoperated brake prevents the machine from running on after the motor has been switched off. An electromagnet Fig. 7 (not shown). arranged above the blade 2 is connected to a switch in the relay controlling the machine motor. When the motor is stopped the electromagnet is energized and raises the blade 2 thus allowing soap cakes on the conveyer 1 to pass the plunger 12.

Title: Improvements in or relating to the automatic frequency regulation of alternating current supplies
IPC: H02J3/08
Filed: 1935-10-18
Abstract: 469,386. Automatic control systems. GENERAL ELECTRIC CO., Ltd., and GIBSON, J. W. Oct. 18, 1935, No. 28866. [Class 38 (iv)] Frequency; load distribution.-In automatically regulating the frequency of a generator or group of generators, the load on a tie line or interconnector between the said generator or group and another generator or group adjusts the permitted integrated frequency error so as to maintain the tie line load. The permitted integrated frequency error is also varied in dependence on the load on the generator or group. Telephone relay contacts 77 are regularly closed by a master clock. Under correct conditions segments 80, 81 of a com mutator driven at a speed proportional to system frequency are not in contact with brushes 86, 87 at such times but when the permitted integrated frequency error is excessive a governor motor 91 is energized by a relay 89 through engagement of one or other of the contacts 80, 81 to annul the excess. A relay 103 responsive to the tie-line current controls a reversible motor 104 through a relay to adjust a torque motor 118, cascaded with torque motors 117, 119 coupling the governor with the contacts 86, 87, so that the permitted integrated frequency error is changed as required to maintain the tie-line load. The torque motor 117, responsive to governor setting, adjusts the said frequency error so that time as indicated by the generator output is retarded with increase of its load. Contacts on the relay 103 control an auxiliary relay 115 to increase the speed of response of the motor 104 upon comparatively large changes in tie-line load.

Title: Breakout table for use with a portable drilling rig
Inventor: FAILING GEORGE EVERETT
IPC: E21B19/16
Filed: 1953-10-20
Abstract: 733,759. Rotary earth-boring apparatus. FAILING CO., G. E. Oct. 20, 1953, No. 28945/53. Class 85. In a portable drilling rig comprising a frame, 2 mounted on a motor vehicle chassis and having spaced guide rails 3, 4 on which a drill head 5 can slide forwardly into the drilling position or be retracted to allow the drill pipe 15 to be lifted from the bore hole, the drill head incorporates a pipe rotating mechanism 6 positioned between hydraulic cylinders 9, 10 the piston rods 11, 12 of which are connected by a crosshead 13 which bears on the top end of a drive rod 14 passing through and rotated by the mechanism 6, the rod 14 carrying a removable chuck at its lower end which grips the drill pipe to rotate the latter whilst it is under downward pressure from the crosshead. To uncouple the stands of drill pipe when the pipe is pulled from the hole a breakout table 17 is provided which utilises the drive from mechanism 6. The table consists of a hollow T-shaped body 18 which is hingedly connected to frame 2 by links 37 so that it can be lifted from the horizontal drilling position shown to an upper position for stowage during transport or lowered to a position clear of the borehole to allow casing to be run, the body housing a rotary element 21 having an axial bore 51 through which the drill pipe extends when drilling and into which roller-type pipe slips 53 can be inserted when the pipe is to be held for uncoupling. A chain 63 connects member 21 to a driving member 33 consisting of a sleeve 66 having upstanding lugs 76 which are engaged by similar lugs on a fitting attached to the drive rod 14 after the drill pipe chuck has been removed therefrom. During drilling, the drive rod 14 is positioned axially over the drill pipe 15 which extends through member 21. When the pipe is to be lifted, the rod 14 is uncoupled by reversal of the drive mechanism after a pawl 85<SP>1</SP> has been engaged with ratchet lugs 86 formed on member 21 to prevent backward rotation of the latter. The drill head is then retracted and the drive rod connected to member 33. The pipe 15 is lifted by a derrick and tackle, the slips 53 being engaged at the first joint 16 which is then unthreaded by rotating the drive rod 14 and members 33 and 21, suitable tongs being applied to the stand of drill pipe to prevent rotation. The lifting tackle is then coupled to the next stand and the operation repeated until the last stand has been removed.

Title: Improvements in or relating to the generation of pulses of high frequency energy
IPC: H03K3/80
Filed: 1946-09-28
Abstract: 638,354. Velocity-modulated tubes. SPERRY GYROSCOPE CO., Inc. Sept. 28, 1946, No. 29042. Convention date, Sept. 28, 1945. [Class 39 (i)] [Also in Group XL (c)] In a reflex velocity modulation valve pulses of ultra-high-frequency are generated by applying an alternating voltage from a transformer 23 to the cavity resonator 12 to cause oscillations only at the voltage peaks and a constant frequency in any one oscillation mode during the peak voltage variation is maintained by applying a varying auxiliary voltage to the reflector 14. The transformer voltage is also rectified and smoothed to produce a negative D.C. voltage across a resistance 37, a part of which is applied by way of a potentiometer 38 connected across a further winding 24 to the reflector 14, an adjustable alternating voltage cophasal with the resonator voltage being thereby added to the reflector voltage. Fig. 2 shows the relations between accelerating and reflector voltages for various oscillation modes; oscillations are generated during a part 57, 56 of the accelerating voltage variation 55, 56, exceeding the minimum voltage 57 for the oscillation mode 51, the mean reflector voltage being determined by the point 53 on the reflector voltage axis and its variation by the difference in ordinates between the points 55 and 56, the line 55, 53, 57, 56 being straight and tangential to the curve 51 since the part 57, 56 is approximately linear and the variations in accelerating and reflector voltage are cophasal and proportional. For the mode 78 no variation of the reflector voltage is necessary. A deformable wall is provided between the resonator 12 and drift tube 20 to tune the former.

Title: Apparatus and method for remedying crosstalk
IPC: H04B3/34
Filed: 1936-10-27
Abstract: 468,735. Preventing inductive disturbance. STANDARD TELEPHONES & CABLES, Ltd. Oct. 27, 1936, No. 29177. Convention date, Nov. 9, 1935. [Class 40 (iv)] The mutual inductance and capacity between each pair of circuits of a multi-core cable are adjusted within a repeater section at a panel or panels at which each circuit intersects every other circuit. The adjusting unit comprises coils 48, 49 in the sides of one circuit and an intermediate movable coil 50 in one side of the other circuit, and a condenser having fixed plates 52, 53 connected to the sides of one circuit and a movable plate 54 connected to one side of the other circuit. Each fixed coil 48, 49 is shunted by a resistance and inductance in series. If there are a small number of circuits, say six, they are led across a single square panel in the manner shown in Fig. 2, so that each of the circuits 1-6 intersects every other circuit. If there are a large number of circuits, they are arranged in groups, and adjustment within each group is made at a square panel, while adjustment between each two groups is made at a rectangular panel shown in Fig. 3; where each of the circuits 1-6 intersects each of the circuits 7-12. The portion of a panel at an intersecting point is shown in Fig. 4, 43, 44 being the incoming and outgoing terminals of one circuit and 45, 46 those of the other circuit. Figs. 8-12 show the spacing of the square and rectangular panels for one up to five groups of circuits, the arrangement being such that the addition of a group or groups to the cable merely requires the interpolation of further panels without disturbing the existing panels. When the scheme is extended beyond six groups, shifting of one or two existing panels may be necessary. It will be noticed that in all cases the panels form a series of groups in which each circuit appears on a panel only once in each group, and that the number of intersections along any pair of circuits preceding or succeeding their point of intersection is the same or differs by unity, thus equalizing the phase shift.

Title: Improvements in and relating to electric signalling systems for indicating measurements at a distant point
IPC: G08C19/26
Filed: 1930-10-04
Abstract: 349,884. Electric signalling systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Pratt, W. H. ; 226. Ocean Street, Lynn, Massachusetts, U.S.A.) Oct. 4. 1930, No. 29741. Convention date, Oct. 4, 1929. (Class 40 (i).] A system for indicating at a distance the readings of a meter comprises a transmitter for transmitting electric current impulses at a rate proportional to a measurement, a receiver comprising an electrical measuring instrument actuated in accordance with the average impulse current, a source from which such impulses are supplied, and means responsive to voltage variations in the source for altering the impulse rate of the transmitter in inverse proportion to the voltage variation. In the construction shown, an integrating watthour meter element 10 is adapted to send impulses over a circuit 11 to a receiver 12. The element produces a torque in a disc 15 mounted on a shaft 16. A magnet 17 acts to damp the rotation of the disc. A member 18 on the shaft 16 closes a contact device 19 once for each revolution of the shaft, whereby current impulses are transmitted through a relay 22. The armature 26 of the relay is connected through a condenser 25 to a source of current 24, which is also connected to a contact 27 adapted to be engaged by the armature when in the attracted position. The armature normally engages a contact 28 connected to the metering circuit 11. Each time the contact device 19 is closed the armature 26 is attracted, whereby the condenser 25 is charged from the source 24, the condenser being discharged over the circuit 11 when the armature 26 returns to normal. In order to allow for variations in the voltage 24, an additional disc 20 is mounted on the shaft 16 for co-operation with an electromagnet 21 to form an electromagnetic induction disc damper for the transmitting instrument. This damper causes the rate of rotation of the transmitter to vary from its true measurement rate, making it slow when the voltage of the source 24 is high and vice versa. The arrangement is such that for variation within certain limits of the voltage of the source 24 accurate indications of the true measurement are obtained at the instrument 12.
