Abstract: 968,630. Washers for rock bolts. ANCIENS ETABLISSEMENTS GOLDENBERG & CIE. May 14, 1962 [May 23, 1961], No. 18478/62. Heading F2H. A layer C of granular material such as sand bound with bitumen, rubber composition or latex or a synthetic resinous composition is located between a plate (on which the layer C may be premoulded, Fig. 3, not shown) and the roof or wall 2 of a mine in which a rock bolt 7 is anchored. The layer C moulds itself to the roof or wall when a nut 8 is tightened on the bolt 7. A preformed hole through the layer may be tapered, Figs. 3, 4 (not shown), or like that 9b in the layer C on the plate P 2  of Fig. 5, it may end in an enlarged frusto-conical recess 11.

Patent GB-220323-A (GB)
IPC: H04L25/49
Filed: 1924-08-07
Abstract: 220,323. Siemens & Halske Akt.-Ges. Aug. 8, 1923, [Convention date]. Order apparatus.-The selector shaft at the transmitting station and the signal reproducing shaft at the receiving station are each adapted to be coupled by magnetically-attracted clutch members to a continuously-rotating driving spindle and to be automatically uncoupled and stopped after one complete revolution. The transmitter keys 26 - - 29, Fig. 2, correspond in number to the number of signals to be transmitted, but for simplicity four only are shown, and each is connected as shown to a corresponding contact segment 21 - - 24 on a fixed distributor disc 18 over which a brush 17 on the selector shaft 5 is arranged to move. This shaft is looked in the initial position, shown in Figs. 1 and 2, by the engagement of a spring-controlled lever 10 in a notch 9 of a disc 8 fixed to the shaft. Depression of any one of the keys 26 - - 29 holds down a spring-controlled yoke 35 and moves a lever 36 from a contact 37 to a contact 38. A condenser 40 which has been charged by a battery B<1> thereupon discharges through an electromagnet 13, thus disengaging the lever 10 from the notch 9. A contact 14 on the lever 10 is thus brought against a fixed contact 15 to close a circuit through an electromagnet 2 fixed on the constantly rotating spindle 1 of the motor M, whereupon an iron disc 6 fixed on the shaft 5 is attracted and coupled to the magnet 2 and the. shaft 5 is rotated. The brush 17 first engages a contact segment 20 on the disc 18 and an impulse sent to line from battery BL energizes an electromagnet LR, Fig. 5, at the receiving station, and moves a lever 51 from a contact 52 to a contact 53 to close circuits for effecting the unlocking and rotation of the type-wheel shaft 5' in a manner similar to the unlocking and rotation of the shaft 5 at the transmitting station. When the brush 17 engages the contact segment connected with the depressed transmitting key another impulse is sent to line and the lever 51 is again moved to close a circuit, through a brush 17<1> on the shaft 5<1> and an extended segment 49 on a fixed distributor disc 18<1>, to a magnet 45 which moves a hammer 46 to press the paper .band 44 against the signal-reproducing wheel 43.. The shafts 5. 5' are each stopped upon completing a revolution by engagement of the levers 10, 10<1> with the notches 9, 9<1> respectively. In a modified arrangement the discs 8, 8<1> are dispensed with, and the shafts 5, 5<1> are each locked by the energizing of a fixed magnet acting to brake the discs 6, 6<1>.

Abstract: 129,900. Wharrad, L. A. Nov. 18, 1918. Handles.-Tool handles and hand-grips for levers or other hand-operated devices, such as change-speed-gear levers, are formed by bending a length of metal of channel or trough section, such that when the ends are brought together parallel a socket is formed for the tang or end of the tool or lever. The tang may be fixed in the socket by soldering or brazing, or may be removably fixed by a contracting nut. As shown in Fig. 1, the tang or end b<2> of a screwdriver b is soldered or brazed in the socket formed by the ends of the bent trough-section piece forming the handle a. The end of the handle may be bevelled as shown, or may fit a shoulder on the tool. As shown in Fig. 6, the handle is clamped on the tang b by a conical nut a<1>. An insulating cap or lining c of celluloid &c. may be placed on the tang b to insulate it from the handle.

Abstract: 1369870 Disproportionation of CHCI 2 F to CHClF 2  FARBWERKE HOECHST AG 25 Oct 1971 [27 Oct 1970 (2)] 18887/74 Divided out of 1369869 Heading C2C Difluoromonochloromethane is obtained by disproportionating monofluorodichloromethane at 0‹ to 50‹ C. in the presence of a chromium oxifluoride catalyst such that the partial pressure of chloroform produced is maintained at less than the vapour pressure of chloroform at the prevailing temperature (e.g. at 70 to 90% of the latter). The disproportionation is generally effected at 0À01 to 1À0 atm. absolute and such that not more than 90% (e.g. 40 to 80%) of the CHCl 2 F is converted. The catalyst used is preferably prepared by fluorinating an hydrated oxide of Cr(III) (e.g. Cr 2 O 3 .2H 2 O) with HF at 150-600‹ C. and is optionally mixed with a binder, e.g. graphite, before use. Examples describe the conversion of CHCl 2 F to CHCIF 2  with the formation of minor quantities of CHF 3  as by-product.

In a circuit arrangement for checking the correct recording or transmission of teleprinter code combinations having a specified number of marking elements by means of a Wheatstone bridge circuit having in one arm a number of resistors R1 ... R5, equal to the number of code elements, and of which a number can be bridged by contacts k1... k5 actuated in accordance with the marking elements of the combination, in a conjugate arm a resistor of value corresponding to the bridging of the specified number of the resistors R1 ... R5, in one diagonal arm a constant voltage U1 and such that from its second diagonal arm a derived voltage U2 can be taken to control a relay TR when the bridge is unbalanced, the resistor R8 in the conjugate arm comprises a number of resistors R81 ... R84 which in toto correspond to signals having one marking element and of which one or more of the resistors can be shortcircuited by a switch S to provide tests for signals having two, three or four marking elements in the 5-unit signal combinations. The arrangement may be used to test 5-unit signals which have two marking elements to represent numerals and the operation of the originating machine to a condition using 5-unit signals with 3 marks for specified functions may control the movement of the switch S to the position (5/3). If the five signals having 4 marking elements and one spacing element are to be used, these signals can be tested by moving the switch S to the position (5/4). The contact Pk is closed during each testing operation, and if the number of contacts k1 ... k5 closed by a signal is incorrect, the bridge Gl is unbalanced and a relay, TR, which may operate an alarm, is energized.

Filed: 1943-11-15
Abstract: 573,549. Cranes. DENYER, A. L. S. Nov. 15, 1943, No. 19024. [Class 78 (iv)] A hoisting device, which is particularly adapted for lifting loaded sacks on to a vehicle, consists of a conventional crane in combination with a prime mover, such as an internal combustion engine. The crane post fits into a socket N on the vehicle and carries an internal combustion engine P, a pump A, a tank F and a cylinder and ram C. The pump is driven through gearing by the engine P and delivers fluid through a controlling valve B to the cylinder C. The upper end of the ram carries sheaves D which are connected by a belt H to sheaves E. The load carrying chain M is connected by a flexible member J passed over sheaves K to the sheaves E. When hoisting is completed the valve B is operated to cut off the delivery of fluid from the pump to the cylinder and to by-pass it back to the tank F. The load is lowered by opening the release valve O which permits the discharge of fluid from the cylinder to the tank. A friction brake G prevents the piston from returning to its lowest position unless it is pulled down by the flexible member. A release valve R is set to blow off at a pressure slightly greater than that required to lift the load.
