Steering-gear; adjusting bogies for steering.- Articulated motor or other vehicles are provided at each end with steering wheels and the centrallypivoted bogies or axles are coupled together resiliently by rods ball-jointed to the bogie pivots, these coupling rods being connected to the steering wheels so as to control the latter. In the construction shown in Fig. 7 a tractor is mounted on two bogies 1, 2 and a trailer on bogies 3, 4 the bogies being coupled together by rods 8, 9, 10, connected to the main frame (not shown) by opposed springs 7. Each vehicle has outer steering wheels 11 and inner non-steering wheels 12. The bogie 3, Figs. 9 and 10, supports the load platform by means of rollers 6, and has the rods 9, 10 connected to it by a ball joint 5, the rod 9 being also connected by a pivoted arm 20 to a lever 21 having a pivot concentric with the ball joint and the bogie pivot. The lever 21 is connected by a pin and slot 24 with a lever 22 pivoted at 15 and adapted to be connected by a sliding pin 18 to a lever 16 which actuates the track rod 19 of the steering wheels 11. The lever 22 is slotted to allow movement of the connection 17 from the lever 16 to the main track rod 19. The coupling rod 10 is connected by an arm 13 to a lever 14 also adapted to be connected by the pin 18 to the lever 16. For running in the forward direction FD, Fig. 9, the pin 18 is lowered by means of a rod 27 and a bell-crank 25 to couple the levers 22, 16 together so that the rod 9 actuates the steering wheels. For the reverse direction of running the pin is raised to connect the rod 10 and lever 14 to the lever 16. The transmission ratios in the steering linkages for forward and reverse running are stated to be altered in the proportions A: (LxA), where A is the distance between the bogie axles and L is the length of the coupling rods.

IPC: F16C1/08
Filed: 1960-11-10
Abstract: 918,547. Flexible shafts. TELEFLEX PRODUCTS Ltd. Nov. 3, 1961 [Nov. 10, 1960], No. 38705/60. Class 80 (2). [Also in Group XXXIV] A torsion cable 8 in a conduit 31 is connected to an operating handle 9 through an irreversible transmission of the type comprising a coil spring frictional locking device 22 arranged so that when the handle drives the cable, clockwise or anticlockwise, the frictional lock is automatically released but if the cable reacts, clockwise or anticlockwise, on the handle the frictional locking grip is increased. As shown, the handle 9 is connected through a ball detent 17 to a drive member 14 rotatable in a fixed casing 10. A drive tag 19-20 (see Fig. 4) loosely mounted on the member 14 lies with clearance in a slot 21 therein and engages a slot in a rotatable member 26 secured to the cable 8, thereby coupling the cable 8 to the member 14 with lost motion. The spring 22 surrounds the member 14 and has inturned ends 23, 24, Fig. 3, engaging between the tag 20 and the shoulders of the slot 21. The coils of the spring 22 frictionally engage the interior of the fixed casing 10. On rotation of the member 14 by the handle 9, one or other shoulder of the slot 21 engages the respective spring end 23 or 24 and contracts the spring coils to release the frictional lock and then rotates the cable 8 through the tag 20. Torsional reaction of the cable, however, acts through the tag 20 to expand the spring coils and increase the frictional lock. In a modification the cable is driven through bevel gearing from a sleeve connected with lost motion to a handle rotating on a fixed spindle which is frictionally gripped by a surrounding locking spring, the spring being expanded to release the lock as the lost motion is taken up when the handle is operated. In other modifications the handle operates through epicyclic or other gearing.

Title: Improvements in or relating to telephone answering machines
Inventor: RHODES JOHN GEORGE LAYCOCK
IPC: H04M1/654
Filed: 1962-10-15
Abstract: 1,056,277. Telephone answering machines. SHIPTON ELECTRONICS Ltd. Oct. 15, 1963 [Oct. 15, 1962], No. 38934/62. Heading H4K. A telephone answering machine includes a " ringing " detector circuit which is provided with a switch for selectively causing the machine to answer a call either upon a ringing signal being received for a predetermined minimum time or, at a predetermined time after the receipt of a ringing signal. The two conditions are selected respectively when the apparatus is connected to an automatic exchange or when connected to a manual exchange. The Figure shows the embodiment in which, in a quiescent state, transistor 1 is cut off, due to the emitter bias from potentiometer R1 and R2, and transistor 2 is conducting and capacitor C3 is therefore partially discharged. On receipt of a ringing signal transistor 1 is turned on thereby discharging capacitor C1 (and C2 if switch S1 is made) and cutting off transistor 2 thus allowing capacitor C3 to charge through resistor R7 with a time constant such that capacitor C3 would reach a potential sufficient to operate relay amplifier 4, and initiate the operation of the answering machine, after approximately 12 seconds. With switch S1 open, however, the charging time constant of capacitor C1 is three seconds, thus unless the ringing signal is repeated, to keep capacitor C1 discharged, transistor 2 will be turned on, discharging capacitor C3, and preventing the operation of the answering device. For use on a manual exchange where the exchange operator may give only a single ring, switch S1 is closed to put capacitor C2 in parallel with C1 to increase the charging time constant to fifteen seconds, the relay amplifier will therefore operate twelve seconds after the first ringing signal, even if the ringing signal is not repeated.

Title: A method of removing solid undesirable inclusions from raw materials
IPC: B03B9/00
Filed: 1963-10-04
Abstract: Raw materials for cement, expanding clays or iron ore sinter which are burnt in a kiln preceded by a multiple stage preheater have unwanted inclusions, which are harder than the raw materials, removed by screening after the raw materials have been broken down in the dry state by raising and dropping them whilst being dried, the heat required for drying being correlated to their moisture content by varying the number of operative stages in the preheater.  In the dropping the raw materials are reduced to a smaller size than the hard inclusions.

Title: Control device for cop changing in an automatic cross winding machine for warp yarn
IPC: B65H67/02
Filed: 1966-09-08
Abstract: 1,130,618. Doffing and donning yarn supply cops. ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI, OBOROVE REDITELSTVI. 8 Sept., 1966 [8 Sept., 1965], No. 40164/66. Heading DID. The invention is concerned with a mechanism for doffing an exhausted cop from an automatic cross winding machine, said doffing taking place only in the absence of yarn from the supply cop. If yarn is present, a knotting operation is substituted for the doffing operation. When the supply of yarn to the take-up package ceases, a shaft 1, Fig. 1, performs one revolution. A two-armed lever 5, on a shaft 4, has an arm 6 biassed against a cam 2 on the shaft 1. If the supply cop is exhausted the twoarmed lever 5 is prevented from being rocked by the cam 2 by means of a plate 63 in the path of movement of the lever 5. If the supply cop is not exhausted, the yarn 59 therefrom extends between the fingers 60, 61 of a comb to displace the fingers thereof in a manner causing a plate 63 to be moved away from the lever 5. When a cop is exhausted the lever 5, as stated, is prevented from following the control cam and shaft 4 is thus not oscillated from a setting in which (a) a first cam 10 on shaft 4 forces a spring biassed pin 15, in a lever 12, to extend into a flange part 18 having a lever 16 engaging a cam 3 on shaft 1; and (b) a second cam 22 on shaft 4 forces a spring biassed pin 27, in a lever 24, to extend into a flange part 31 having a lever 28 engaging a cam 67 on shaft 1. The levers 12 and 24 are thus forced to oscillate about the shaft 4 when the shaft 1 turns the cams 3 and 67; the resulting movement of lever 12 is used to initiate the ejection of an exhausted bobbin; and the resulting movement of the lever 24 is used to initiate the transporting of a full cop to the wind-off position. When a cop is not exhausted the lever 5, as stated, is permitted to follow the cam 2 and rock the shaft 4. Rocking of the shaft 4 causes the cams 10, 22 to move to a setting in which they permit the spring biassed pins 15, 27 to retract from the flanges 19 and 31. When this happens the levers 12, 24 no longer respond to the cams 3 and 67 and cop ejection and replacement do not take place. Cop ejection. When the lever 12 is rocked, as above, a two-armed lever 44 Fig. 2 lowers the exhausted cop onto a chute 39 where it is doffed. Cop replacement. When the lever 24 is rocked, as above, it causes a ratchet mechanism 52 to turn a wing element 41 in a pot-shaped magazine 36 in a manner moving a full cop 38 to the chute 39 and hence to the wind-off position. The pot-shaped magazine 36, wing element 41 and chute 39 are the subject of the claims in Specification 1,130,619.
