Title: Improvements in or relating to prisms for optical instruments
IPC: G02B23/00
Filed: 1946-03-13
Abstract: 622,107. Prisms. SORDOILLET, P. March 13, 1946, No. 7882. Convention date, March 13, 1945. [Class 97 (i)] A glass prism is inserted between the object lens 12 and the eyepiece 18 of an optical instrument, e.g. field glasses, so that the light passing through the object lens is incident normally on the face 3<SP>1</SP> of the prism. After passing through this face undeviated, the light is reflected at an inclined flat face 4 on to a surface 3<SP>2</SP>, parallel to surface 3<SP>1</SP>, and is then directed on to the silvered portion 9 of a face 2<SP>1</SP>, which is parallel to the optical axis of the instrument and which reflects the light onto the silvered portion 10 of the face 2<SP>2</SP>. Face 2<SP>2</SP> is parallel to the face 2<SP>1</SP> and reflects the light on to a roof-shaped face 6 whereby it is reflected through surface 3<SP>2</SP> on to the eyepiece 18. The light rays thus avoid the central part of the prism, which may have a central cavity 19 to reduce the weight of the prism and to allow the insertion therein of a fixing member.

Title: Improvements in automatic bobbin changing mechanisms for looms
IPC: D03D45/20
Filed: 1959-03-09
Abstract: 914,066. Automatic bobbin changing looms. RUTI MACHINERY WORKS Ltd. March 9, 1959 [March 8, 1958], No. 8071/59. Class 142 (2). Colour selection.-In a multi-colour bobbin changing loom, a bobbin is released from the appropriate compartment of the magazine by depression of a rod 65, Fig. 4 (one for each compartment), by a continuously-oscillating presser 61, such depression occurring when an intermediate member 52 is interposed as shown between the presser and the rod under the control of the change box motion and the cop feeler. The intermediate members are carried by slideways 50 pivoted on a spindle 51 and slidable along the spindle to accompany a bar 30 which is moved endwise by the change box motion. The intermediate members are set by striking plungers 33 held retracted by locking- plungers 37; a locking plunger can be disengaged by a finger 41 on a shaft 40 rocked by an electromagnet controlled by the cop feeler. The spacing of the intermediate members differs from that of the fingers 41 and rods 65 so that at any position of the bar 30 only one locking plunger 37 is in range of a finger 41 and only the associated intermediate member registers with the associated presser 61 and rod 65. When a depleted shuttle arrives in the single-celled shuttle box at the magazine end of the loom, the feeler causes the corresponding intermediate member 52 to be interposed, as shown, between its presser 61 and rod 65; the shuttle is then picked into the change box. If the shuttle immediately returns to the magazine end, the presser 61 depresses the intermediate member 52, which slides down the slideway 50, thereby depressing the rod 65 to release a bobbin from the magazine; a pin 72 on the rod 65 rocks a fork 71, and hence a shaft 70, to bring the transfer hammer into operation. As the intermediate member descends, a roller 57 on its upper end rocks a bent lever 55 to retract the striking plunger 33 which is again locked by the plunger 37. If the change box moves after a depleted shuttle has been felt, endwise movement of the bar 30 takes the intermediate member out of line with the presser 61 and rod 65; the need for replenishment remains stored until the shuttle is again picked to the magazine end of the loom. Magazine.-The bottom bobbin in each compartment of the magazine, Fig. 7, is held by flaps 88, one under the head and one under the tip of the bobbin. When a rod 65, Fig. 4, is depressed, it rocks a shaft 85, Fig. 7, to withdraw the flaps 88, allowing the bottom bobbin to fall under the transfer hammer (not shown) where it is retained by a spring-loaded flap 93. Meanwhile, spring- loaded flaps 90, normally held clear by projection on the flaps 88, grip the next bobbin.

Title: Automatic insertion system for a stand-by clock signal in a pcm multiplexing system

Abstract: 1374146 Pulse signalling SOC ITALIANA TELECOMTJNICAZIONI SIEMENS SpA 22 Feb 1972 [22 Feb 1971] 8216/72 Heading H4L  A standby clock signal is inserted automatically in a PCM time division multiplex system in the event of failure of the normal clock signal generator. As shown, a main terminal, Fig. 1, is connected by lines r, a with a remote station, Fig. 2. At the main terminal, clock signals from CP are supplied via AND gate n 1  and OR gate 01 to a multiplexer Áp receiving two-level P.C.M. signals on lines J 1  to J K  and converting them to three-level P.C.M. signals for transmission. The clock signal is also supplied to a unit Kp which enables gate n 1  when the clock frequency is correct. A three-level P.C.M. signal received on line r is converted to two-level at Sp and a clock signal is derived and supplied to a gate n2 which is normally inhibited by the inverted output from Kp. The received P.C.M. signal, after conversion to two-level, is de-multiplexed at #p and supplied to outputs B 1  to B K . At the remote terminal, Fig. 2, the P.C.M. signal received on line a is converted to two-level at S L  and a derived clock signal is supplied via normally open gate n 4  and OR gate 02 to a multiplexer Á L  which receives two-level P.C.M. signals on lines G 1  to G K  and converts them to three-level signals for transmission via line r. The two-level P.C.M. signals from S L  are demultiplexed at # L  and supplied to lines E 1  to E K . The demultiplexer also supplies to unit K R  a signal g* in which logic value 1 indicates that the received clock signal is of the correct frequency and a signal f* in which logic levels 1 and 0 indicate regular receipt of the P.C.M. signal and absence of the P.C.M. signal respectively. With normal working, circuit K R  produces an output of logic level 0 which is inverted and supplied to gate n4. If the clock frequency is incorrect, this is detected at Kp, Fig. 1, and its output u goes to logic value 0 so that gate nl is blocked and gate n2 is enabled, allowing the derived clock pulses to be supplied via OR gate 01 to the multiplexer. At the remote terminal, the demultiplexer detects the change in clock frequency and switches signal g* to level 0 so that the output from K R  is at level 1. This blocks gate n4 and enables gate n3 so that clock signals from a standby generator C R  are supplied via OR gate O 2  to the multiplexer Á L . A unit K S , identical to unit Kp, monitors this clock signal and stops the multiplexer Á L  if the frequency is incorrect. If the clock generator C P  at the main station stops, no signals are received at the remote station so that signal f* from the demultiplexer # L  switches to level 0 and the output of KR switches from level 0 to 1. This blocks gate n4 and enables gate n3 to bring the clock generator C R  into use. At the main station, the absence of a clock signal causes unit Kp to block gate nl and enable gate n2 to bring the derived clock signal into use.
